From autoimmune thyroid disease and CREST syndrome to incidental discovery of incipient gastric carcinoma: a case report.


Autoimmune thyroid disease (AITD), including Graves' disease and Hashimoto's Thyroiditis (chronic autoimmune thyroiditis), is a well-documented clinical entity and the most common organ-specific autoimmune disorder, occurring mostly in middle-aged women [1-3].

The main characteristic of the disease is the lymphocytic infiltration of the thyroid gland and the presence of circulating anti-thyroid antibodies (anti-thyroperoxidase, anti-thyroid stimulating hormone, anti-thyroglobulin) [4].

AITDs often concur with other autoimmune diseases, giving rise to the concept of overlap syndromes, which are defined as the coexistence of two or more autoimmune disorders in one individual [5, 6].

Previous studies have reported the association between AITDs and systemic scleroderma, an autoimmune connective tissue disorder characterized by systemic inflammation, microvascular abnormalities, and fibrosis of the skin and internal organs [7-10].

However, there have been only few reports of AlTDs associated with CREST syndrome (Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly and Telangiectasias), a limited form of scleroderma [11].

Furthermore, these disorders have been associated with lymphoid malignancies [12, 13], but only rarely with other cancers such as lung, breast, duodenum [14-16].

We herein report a case of incipient gastric adenocarcinoma uncovered during the evaluation of overlap syndrome between autoimmune thyroiditis and CREST syndrome.

Case Report

We report the case of a 59 year-old female patient who came to the Endocrinology Clinic for vertigo, dysphoria, and fatigue.

The patient's history revealed that she suffered from Raynaud's phenomenon for the past ten years, for which she did not seek medical attention. She was hypertensive for approximately seven years, currently under treatment with angiotensin II receptor blockers (ARBs) and calcium channel blockers (CCBs).

The patient had a family history of cardiovascular diseases and metabolic syndrome, but no autoimmune diseases or malignancies were reported.

On admission to our clinic the patient was overweight (with a BMI of 28.1 kg/[m.sup.2]), with normal pulmonary and cardiovascular parameters, a resting heart rate of 70 bpm and a blood pressure of 150/100 mmHg.

Clinical examination revealed: erythema of the face, thin lips, erased expression lines, mild hardening of the skin, telangiectasias (Figure 1) of the lips, face and palms, sclerodactyly (Figure 2), non-pitting edema of the lower limbs, subcutaneous calcinosis (Figure 3) in the extensor surface of the joints (elbow and knee), bilaterally and mildly impaired strength prehension.

Laboratory findings showed normal blood cell count, mild elevations of the sedimentation rate (16 mm/h), high total cholesterol (268 mg/dl), LDL cholesterol (180 mg/dl) and triglycerides (232 mg/dl). Renal and hepatic parameters were within normal limits, while glucose levels were slightly elevated (107 mg/dl).

Immunological assays revealed autoimmune thyroiditis (high levels of anti-thyroperoxidase antibodies) with euthyroid status (normal thyroid stimulating hormone and free thyroxin levels) and the presence of anti-nuclear antibodies (ANA), with high titers of anti-centromere antibodies (675 UI/ml) and anti-chromatin antibodies (243 UI/ml), but negative Scl-70 antibodies.

Neck ultrasound revealed a small thyroid parenchyma (total volume of 6.6 ml), highly heterogeneous, with multiple discrete hypoechoic micronodules and normal vascularity, which is strongly suggestive for chronic thyroiditis.

With the purpose of investigating the patient's main symptom (severe vertigo) we recommended a neurological exam which did not reveal any pathological elements and the brain MRI did not find any cerebral lesions.

Electrocardiogram at rest was normal and the 2D transthoracic Doppler echocardiography showed concentric left ventricular hypertrophy, normal and symmetrical contractions with a normal ejection fraction of 68%. Doppler ultrasound of the carotid arteries revealed atherosclerosis with calcified plaques at the origin of the left internal carotid artery, with a 20% stenosis.

Cervical spine x-ray showed an inverted physiological curvature at the C3-C4 level, with arthrosis and a narrowing of the spinal canal at the C4-C7 level.

The otorhinolaryngology examination found a normal audiogram, normal caloric-vestibular test, negative head-shake, therefore could not establish an organic cause for the symptoms.

Based on the clinical picture (calcinosis, Raynaud's phenomenon, sclerodactyly and telangiectasias) and immunological findings (high levels of anti-centromere and anti-chromatin antibodies), a diagnosis of CREST syndrome was made and cyclosporine treatment was recommended.

To further evaluate any esophageal involvement of the scleroderma, an esogastric radioscopy was performed, which visualized two lacunar images in the pyloric antrum and hypertrophic gastric folds (Figure 4).

Upper gastrointestinal endoscopy revealed on the greater gastric curvature two ulcerated polypoid tumors with an apparent common base of 1.5-2 mm and biopsy from the tumors found intramucosal gastric adenocarcinoma.

The patient was then directed to the Surgery Department of the Regional Institute of Oncology Iasi, where a total gastrectomy was performed, with a "roux-en-y" anastomosis (termino-lateral eso-jejunoanastomosis and termino-lateral jejuno-jejunoanastomosis).

Pathology report revealed a well-differentiated tubular adenocarcinoma with superficial submucosal infiltration--[pT.sub.1b][N.sub.0][M.sub.1].

The patient had a favorable postoperative evolution and the prognosis is good due to the very early diagnosis of the gastric malignancy.

However, taking into consideration this recent diagnosis, the immunosuppressive treatment with cyclosporine for CREST syndrome was deferred.


AITDs are the most common autoimmune disorders in humans and have a higher prevalence in the female population, women: men ratio of 4:1 [3, 17, 18]. AITDs have been reported to be commonly associated with other autoimmune diseases such as vitiligo or systemic sclerosis (scleroderma), but only rarely with CREST syndrome [19, 20].

Studies have shown that the association of autoimmune disorders is more than coincidental, identifying a common genetic background and an autoimmune underlying mechanism [6, 21].

Several publications informed of a possible increased risk of malignancies in scleroderma, particularly lung, breast, lymphoid and hematological neoplasms [14].

A few older papers suggested a possible link between gastric carcinoma and systemic sclerosis, on an atrophic gastritis and Helicobacter pylori (H. pylori) background, which were strongly associated with esophageal hypomotility [22]. However, our patient had hypertrophic gastric folds on gastroscopy and was negative for H. pylori.

Our case presentation confirms the possibility of overlap syndrome between autoimmune thyroiditis and CREST syndrome and highlights the importance of a multidisciplinary approach of the patient with autoimmune disorders.

Moreover, the serologic confirmation of CREST syndrome in a patient without any digestive symptoms could have masked the presence of the gastric malignancy.

The screening for esophageal dysmotility in our patient allowed for the early diagnosis of an otherwise silent disease, frequently discovered in the complications stages.


In summary, thyroid and connective tissue autoimmune diseases may overlap with each other and together may mask the existence of malignancies.

It is important to be aware that CREST syndrome and autoimmune thyroiditis can coexist and a thorough evaluation of both conditions and gastric cancer screening may be necessary even in patients who do not complain with digestive symptoms.
