Although no case of metastasis has been reported, this malignancy can be locally aggressive, and it often recurs following incomplete excision. We report the case of a young woman with a very large GCRG of the right temporal bone. We discuss the clinical picture, differential diagnosis, histologic evaluation, appearance on computed tomography and magnetic resonance imaging magnetic resonance imaging (MRI), noninvasive diagnostic technique that uses nuclear magnetic resonance to produce cross-sectional images of organs and other internal body structures. , and treatment options. We also review the cases of temporal bone GCRG that have been reported in the literature so far.
The term giant-cell reparative granuloma (GCRG) was introduced by Jaffe in 1953 to describe a lesion of the mandible and maxilla that occurred following a trauma-induced intraosseous hemorrhage. (1) He also distinguished GCRG, which is not a true neoplasm neoplasm or tumor, tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. , from giant-cell tumor. Since 1953, GCRG has been reported in many other sites, including the axial skeleton and long bones, (2) the hands and feet, (3) the facial bones, (4) the cranial vault, (5) the sphenoid sphenoid /sphe·noid/ (sfe´noid)

Although GCRG of the temporal bone has been purported to be a reaction to cranial trauma, (1,2,11,12) its pathogenesis remains unclear. (13,14) It can occur at any age, and there does not appear to be a clear gender predilection. (13) Reported symptoms include hearing loss, tinnitus, a palpable mass, pain, vertigo, and facial weakness. (14) Complete surgical excision is regarded as the treatment of choice.

medical curettage of the lesion is not sufficient. (13,14) Whenever complete removal is not possible, radiotherapy should be considered. (13-15) Following complete excision, the prognosis is good, and reported recurrence rates have ranged from 10 to 15% in most studies. (11,16-18)

To our knowledge, infiltration of the temporal lobe by a temporal bone GCRG has not been previously described in the literature.
A 17-year-old girl came to the Department of Otorhinolaryngology-Head and Neck Surgery in October 1998 with a 2-month history of hearing loss in her right ear. She reported no other symptoms, and she had no history of head or acoustic trauma or exposure to ototoxic ototoxic /oto·tox·ic/ (o´to-tok?sik) having a deleterious effect upon the eighth nerve or on the organs of hearing and balance.

Examination of the head and neck revealed that a mass was obstructing the right auditory canal and had almost completely occluded the lumen. Pure-tone audiometry revealed normal function in the right inner ear and a 20 dB air-bone gap at all frequencies tested. Serum levels of calcium, alkaline phosphatase, phosphorus, and parathyroid hormone were within normal limits. Computed tomography (CT) demonstrated a 4-cm osteolytic lesion of the right temporal bone and infratemporal fossa with intracranial intracranial /in·tra·cra·ni·al/ (-kra´ne-al) within the cranium.

Because of the contrast enhancement, a preoperative embolization of the lesion was performed. Intraoperative rapid section revealed a tumor of unclear dignity. For that reason, the operation was abandoned after the mastoidectomy Mastoidectomy Definition

The patient was scheduled to undergo a complete removal of the lesion, but unfortunately she and her mother refused the recommended surgery.
In February 2001, the young woman returned to our institution. Since her initial treatment, time tumor had grown significantly and the patient was experiencing total right-sided sensorineural deafness, intermittent vertigo, tinnitus, facial weakness (House-Brackmann grade II-III), and paresthesia paresthesia /par·es·the·sia/ (par?es-the´zhah) morbid or perverted sensation; an abnormal sensation, as burning, prickling, formication, etc.

There were erosions of the labyrinth and the bony canal of the internal carotid artery as well as destruction of the right cochlea cochlea (kŏk`lēə): see ear. .

The lesion was resected via a combined pterional and infratemporal approach. The operation was performed in cooperation with the Department of Maxillofacial Surgery and the Department of Neurosurgery, and we were continuously assisted by computer-navigation control (Stryker Leibinger Navigation System; Freiburg, Germany). The tumor had damaged a large portion of the right temporal bone. The internal carotid artery, the facial nerve, and the mandibular nerve were ensheathed.

MRI with gadolinium contrast 2 weeks following surgery revealed no signs of residual tumor (figure 3). Postoperatively, the patient exhibited a profound weakness of the right facial nerve (House-Brackmann grade V), but she gradually experienced a complete recovery within 6 months. Her vertigo gradually resolved over 4 weeks. During the first 12 months postoperatively, she complained that her powers of concentration had diminished. She also reported a permanent numbness in the area of the right mandibular nerve and total right-sided deafness.
In view of the size of the tumor and the involvement of bone, muscle, connective tissue, the mandibular joint, the dura mater, and the brain, postoperative radiation was recommended by the Department of Radiation Therapy, but the patient declined. Further treatment of the altered occlusion of her mouth was administered in the Department of Maxillofacial Surgery. The most recent MRI was conducted in March 2003, and there was no sign of recurrence.

(19) When it does occur, it most often arises in the mandible and maxilla; it can also involve any other bone in the jaw, cheek, and extragnathic region. (20) Including our patient, only 18 cases of GCRG of the temporal bone have been reported in the international medical literature (table). This group includes 6 females and 12 males, aged 4 months to 72 years (mean: 30.2 yr). Although different authors have reported that GCRG of the jaw has a predilection for females, (1,17,21,22) such does not appear to be the case for GCRG of the temporal bone. Even so, because of the small number of cases that have been reported, it is not possible to speculate whether there is a true gender predilection for temporal bone GCRG.
Among the 13 cases in which the authors specified the length of follow-up, monitoring time ranged from 10 months to 15 years (mean: 3.8 yr). Three reports contained no information on the length of follow-up, and two contained no information on follow-up at all. Of the 16 patients who were followed up after treatment, only two (12.5%) experienced a recurrence.
Symptoms. The reported symptoms of GCRG of the temporal bone include heating loss, tinnitus, a palpable mass, pain, vertigo, and facial weakness. Conductive hearing loss Conductive hearing loss

Tinnitus and a palpable mass were noted in 5 patients each (27.8%), pain in 3 (16.7%), and vertigo and facial weakness in 2 each (11.1%). One patient (5.6%) also complained of dysphagia and protrusion protrusion /pro·tru·sion/ (-troo´zhun)
1. extension beyond the usual limits, or above a plane surface.
2. the state of being thrust forward or laterally, as in masticatory movements of the mandible. .
Etiology. The pathogenesis of GCRG is still controversial. (13,14) Jaffe wrote that the lesion represents a hyperplastic, reparative reaction to an intraosseous hemorrhage induced by trauma. (1) Many authors still share this opinion. (2,12) It must be mentioned, however, that there was no history of head trauma or previous surgery in 9 of the 18 cases of temporal bone GCRG. In another 5 cases, the authors did not report whether there had been any trauma. In fact, only 4 cases involved some previous trauma to the head. In one of those reports, the authors claimed that the lesion had occurred secondary to blunt trauma inflicted by a cricket bat. (19) However, the fact that this trauma had occurred only 6 weeks before the patient sought treatment for his tumor makes it most unlikely that the 3 x 2 x 1.5-cm GCRG had actually been caused by that particular trauma. Other causes that have been proposed include infections, (11) developmental anomalies, (17) and hormonal influences, (23) but no single theory has gained wide acceptance. (14)
Differential diagnosis. The diagnosis of GCRG is based on the combination of clinical information, radiologic data, histopathologic characteristics, and response to treatment. (13) GCRG must be differentiated from the brown tumor of hyperparathyroidism Hyperparathyroidism Definition

(12-14,18)
Brown tumor of hyperparathyroidism. The histologic appearance of the brown tumor of hyperparathyroidism is often indistinguishable from GCRG. (10,13,14) Still, the differentiation between the two can be made without difficulty by measuring serum calcium, phosphorus, and alkaline phosphatase levels. (21) as well as phosphate clearance and levels of parathyroid hormone and urine hydroxyprotein. (13)
Aneurysmal bone cyst. Aneurysmal bone cyst is another non-neoplastic, reparative process with a giant-cell component. (13,24) A cystic blow-out of the bone is a typical finding on plain x-ray. (21) On MRI, aneurysmal bone cyst is usually not homogeneous and is characterized by a high signal intensity. (12,13) Histologically, it is characterized by thin-walled, blood-containing cystic cavities that are lined with flat fibroblastic cells and bony giant cells. (24) Aneurysreal bone cyst cyst, abnormal sac in the body, filled with a fluid or semisolid and enclosed in a membrane. Cysts can be congenital but are usually acquired, the most common locations being the skin and the ovaries. of the temporal bone is exceedingly rare, as only 10 cases have been reported in the literature. (24) Chondroblastoma. Chondroblastoma of the head and neck is most often located in the temporal bone. (20) It is characterized by local recurrence and metastasis, and it should be considered clinically to be a malignant tumor. (25) Its important histopathologic features are focal chondroid differentiation, intercellular intercellular /in·ter·cel·lu·lar/ (-sel´u-lar) between or among cells.

n. , immature bone trabeculae, and fibro-osseous tissue in the affected part of the bone. (27) Its signal intensity is typically low on both T1 and T2-weighted MRI. (12) Fewer than 80 cases of temporal bone fibrous dysplasia have been reported in the international medical literature. (27)
Cherubism. Cherubism is a rare, benign, autosomaldominant inherited condition characterized by cystic proliferation of the mandible and maxilla in childhood. (28,29) Histologically, it features proliferating vascular fibrous tissue with osteoclastic, multinucleated giant cells. (28) Radiologically, there is a specific finding of bilateral, multilocular multilocular /mul·ti·loc·u·lar/ (-lok´u-ler) having many cells or compartments.

Osteosarcoma. There might be a large, benign giant-cell component to osteosarcoma, but the presence of atypia of the mononucleated cells is a useful criterion in making the differential diagnosis between it and GCRG. (20)
Giant-cell tumor. Giant-cell tumor is often difficult to distinguish from GCRG. (13,14,20) Prior to Jaffe's report in 1953, (1) all giant-cell lesions were designated as giant-cell tumors.(14) GCRG has often been misdiagnosed as giant cell tumor, (14,21) especially during the years before the first reported case of temporal bone GCRG by Hirschl and Katz in 1974. (11) True giant-cell tumor is a real neoplasm, and it accounts for 3 to 7% of all primary bone tumors. (13) In most cases, it occurs at the ends of long bones. (20,30) Bertoni et al reviewed 2,046 cases of giant-cell tumor and found that only one had occurred in the temporal bone. (20)
The primary difference between giant-cell tumor and GCRG is the prognosis. (13) Giant-cell tumor is reported to have a higher incidence of recurrence than GCRG; reported recurrence rates of giant-cell tumor of the long bones range between 45 and 62%. (14) Giant-cell tumor may undergo malignant transformation, (13,14) and metastatic spread, usually to the lung, occurs in 1 to 6% of cases of giant-cell tumor of the extremities. (14,31) In giant-cell tumor of the craniofacial craniofacial /cra·nio·fa·cial/ (kra?ne-o-fa´sh'l) pertaining to the cranium and the face.
Of or involving both the cranium and the face. bones, only one case of lymph node metastasis and no case of pulmonary metastasis has been noted. (14)
On radiologic evaluation, giant-cell tumor and GCRG are indistinguishable. (13,14) On CT, both usually appear as a nonspecific nonspecific /non·spe·cif·ic/ (non?spi-sif´ik)
1. not due to any single known cause.
2. not directed against a particular agent, but rather having a general effect.

2. producing lysis.

2. lesion. (13,14) On MRI, most lesions reflect a low signal intensity on T1-and T2-weighted imaging. (13,14) Both tumors enhance with gadolinium contrast; the degree of enhancement ranges from slight (12) to strong. (13)
Because of the nonspecific nature of the radiologic findings, the differentiation between giant-cell tumor and GCRG must be made histologically. Giant-cell tumor originates in the connective tissue of bone marrow, whereas GCRG arises from periosteal periosteal /peri·os·te·al/ (-os´te-al) pertaining to the periosteum.
pertaining to or emanating from the periosteum. connective tissue. (13) Several histopathologic differences between the two lesions have been described in the literature. GCRG has been reported to contain fewer multinucleated giant cells than has giant-cell tumor. (14) The giant cells in giant-cell tumor tend to be more evenly distributed and have a more uniform appearance.(11,14,18) GCRG is associated with a greater degree of osteoid formation, hemorrhage, hemosiderin deposition, and inflammation. (14) The spindling spin·dling
Spindly. quality of the cells that encircle the giant cells has been described as a consistent feature of GCRG. (4,18,20) In giant-cell tumor, typical findings are foci of necrosis and the presence of marked mitotic activity. (14)
There may be areas of a GCRG lesion that cannot be histologically differentiated from giant-cell tumor. (20) Ung et al recommended maintaining the current nomenclature of giant-cell tumor and GCRG whenever a clear distinction between the lesions can be made histologically. (14) In borderline cases, however, they preferred the term giant-cell lesion, which can be further classified as aggressive or nonaggressive on the basis of symptoms. (14) However, we agree with Bertoni et al that it is important to make every effort to separate giant-cell tumor of the skull from GCRG because the prognosis of giant-cell tumor is generally much worse. (20) Bertoni et al described 15 cases of giant-cell tumor of various skull bones; 3 of those patients died of giant-cell tumor. (20) To the best of our knowledge, there is not a single reported case of death caused by GCRG.
Treatment. Complete surgical excision is the therapy of choice for GCRG. (13,14) Some authors have claimed that curettage is sufficient for treatment. (1,15,21) However, Auclair et al noted that the recurrence rate following simple curettage of GCRG was 50%, compared with a recurrence rate of only 10% following complete surgical excision. (31) For large tumors, preoperative superselective intravascular intravascular /in·tra·vas·cu·lar/ (in?trah-vas´ku-lar) within a vessel.
Within one or more blood vessels. embolization has been advocated. (32) Unlike giant-cell tumor, GCRG does not undergo malignant transformation, and there is not a single documented case of GCRG metastasis. (14)
Complete excision of giant-cell tumors of the long bones can usually be performed without major difficulty. However, the skull base, with its large number of vital structures, provides a significant challenge to complete surgical removal. (14) In cases where complete resection is not possible, postoperative radiation has been advocated. (13,16) Of the 18 patients who have had GCRG of the temporal bone, 3 underwent radiation therapy--2 after a complete resection and 1 after an incomplete resection. The size of the radiation doses varied greatly--from 600 and 5,000 cGy. Especially in young patients, radiation therapy for this primarily benign lesion should be performed only when complete resection is not possible or when the tumor has infiltrated many different structures, as happened in our patient. Keep in mind that any radiation therapy carries the potential risk of sarcomatous transformation in the decades to come. (14) On the other hand, patients with giant-cell tumor of the temporal bone should always undergo radiation following resection in light of the high risk of recurrence. (20)
De Lange et al (22) and Pogrel et al (33) reported a total of six patients with GCRG of the jaw who experienced a complete remission alter they were treated with calcitonin calcitonin /cal·ci·to·nin/ (-to´nin) a polypeptide hormone secreted by C cells of the thyroid gland, and sometimes of the thymus and parathyroids, which lowers calcium and phosphate concentration in plasma and inhibits bone resorption. . Anti-inflammatory drugs may play a future role in the treatment of GCRG, but more data are needed, especially long-term results, before calcitonin treatment can be regarded as an adequate alternative to surgery.
