A 42-yr. old man presented with chief complaints of nasal blockage, nasal bleeding and later on pain in the eyes and headache and progress to nasal mass within period of 3 months. Routine haematological and biochemical investigations were done, which were normal at the time of presentation. Nasal endoscopy was done which showed nasal mass which bleeds on touch. A computed tomography (CT) scan face and neck revealed an inhomogenously enhancing soft tissue density lesion measuring 5.7*3.3*3.9 cm involving left maxillary sinus extending to left ethmoid sinus, left nasal cavity reaching up to posterior choana abutting the nasal septum (Figure 1).

Sinonasal teratocarcinosarcoma (SNTCS) is a very rare and aggressive neoplasm of malignant potential histologically characterized by the combination of one or many components of epithelial and mesenchymal elements. (1) It is characterized by the histologic combination of malignant teratoma and carcinosarcoma with a triphasic growth pattern including epithelial, mesenchymal and primitive neuroectodermal components (2), and it mainly occurs in the nasal cavity and paranasal sinuses, although tumours occurring at other locations like nasopharynx and oral cavity have also been described. (3,4,5)

These tumours has an insidious onset and patient become symptomatic after the tumour invades the surrounding tissues in advanced stages making the overall prognosis poor. (6) The rare presentation of these tumours and varied combination histopathological features, with its infrequency and the complex phenotypic compositions the lesions are often misdiagnosed, leading to difficulties in management. (7) Here we report a case of locally advanced nasal teratocarcinosarcoma managed by chemoradiotherapy.


Endoscopic excision biopsy was done and the dark brown soft tissue pieces measuring 4*3.5*1.5 cm were sent for histological examination. All blocked in 3217A-C/16. The viable fragments show a biphasic tumour composed of epithelial and mesenchymal components. The epithelial component is composed of small round to oval cells and scant cytoplasm arranged in sheets. Some areas of epithelial component show Homer-Wright and Flexner Wintersteiner rosettes while some areas show primitive neuroectodermal component with gland formation.

The intervening mesenchyme is composed of plump to spindle shaped cells. Areas of epithelium to mesenchymal transition are also seen. Further on immunohistochemistry, tumour showed CK, Chromogranin A, NSE in epithelial component; CD99 focally positive in epithelial component; Vimentin diffusely positive in stromal and focally positive in epithelial component; Ki67 focally high in epithelial component; Myf4 was negative.

Thus, a histopathological and immunohistochemical diagnosis of teratocarcinosarcoma was made. Blocks were reviewed showing features consistent with the diagnosis.


Patient underwent excision biopsy of nasal mass via transnasal approach. In view of residual disease, patient was managed with Intensity Modulated Radiotherapy with 6 MV energy on linear accelerator and total radiotherapy dose of 68 Gray (Gy) to Gross tumour volume (Which is gross residual disease post operation), 66 Gy to Clinical Target Volume (To include micro metastasis), 64 Gy to Planning Target Volume and 58 Gy to neck nodes in 33# over 6.3 weeks along with concomitant systemic chemotherapy with injection Cisplatin-40 mg/[m.sup.2] weekly. Common complications of concurrent chemoradiation were Grade II to Grade III mucositis leading to swallowing dysfunctions which were managed with supportive care.

Follow up CECT neck on 6th April 2017 shows soft tissue thickening measuring 1.2*1.7*1.9 cm involving the left maxillary sinus extending to left ethmoid sinus, left nasal cavity reaching up to posterior choana suggestive of post treatment changes. Now patient is on follow up from last 2 years with no evidence of recurrence.



Microscopically sinonasal teratocarcinosarcoma consists of primitive neuroepithelial elements with more than one malignant epithelial and mesenchymal components probably originating from stem or pluripotent progenitor cell with multidirectional differentiation. (8,9) Cervical node metastasis are seen in 17% and no elective neck dissection is indicated. (6) The term teratocarcinosarcoma was coined in 1984 by Heffner and Hyams in view of its complex histopathological pattern. Histologically, it is different from true carcinosarcoma which consists of a single malignant mesenchymal component, whereas SNTCS has one or many epithelial and mesenchymal components (both benign and malignant). (1) Despite several studies, the histogenesis of this tumour remains controversial. Common clinical features include nasal obstruction and epistaxis with the average duration of symptoms being reported at 3.5 months/10) Incidence is seven times higher in males. (11,12) Currently, 97 cases have been reported in world literature/6) Heffner and Hyams justified the term "teratocardnosarcoma" in his case series on 20 patients ranged from 18 to 79 yrs. with median age of 60 yrs., the histological features differed from gonadal germ cell neoplasms. They suggested aggressive multimodality method of treatment including surgery, radiotherapy and chemotherapy, as only 40% of the patients lived more than 3 years and average follow up was 6.1 yrs. (13)

Multiple modality treatment including surgery, chemotherapy and radiation therapy is the treatment of choice. According to Budrukkar et al, combination of radiotherapy and surgery offer best five-year survival rate of 50% followed by surgical treatment.

Local recurrence after surgery was seen in 30 to 43%, hence adjuvant treatment is recommended in the form of radiation and chemotherapy. (10,14) As the tumour is highly aggressive and rare, no adequate radiotherapy doses are described and individualization of therapy should be considered. (8,9) The complex tumour shape and close proximity to critical structures has made 3D CRT (3dimensional conformal radiotherapy) and IMRT (Intensity Modulated Radiotherapy) better in delivering higher radiation doses to the target volumes.
