Seborrheic Keratosis: Report of a Rare Presentation and Reminder of the Current Knowledge of the Problem.

A 75-year-old man presented with an abdominal enlarging painless tumor of the skin evolving over the last 30 years. His past medical history was unremarkable. Physical examination revealed a brownish pedunculated cutaneous mass which had an irregular keratotic warty surface with no discharge or ulceration. The mass was clinically presumed to be a melanocytic tumor, or a verrucous carcinoma. A monoblock excision of the mass was performed with a good outcome. The specimen was then sent to our pathology department to rule out malignancy. Macroscopic examination revealed a brownish tumor of 7.5 × 7 × 1.5 cm which had fissures and cauliflower-like appearance. Final histological report concluded to a giant seborrheic keratosis.

Small Intestine Gastrointestinal Clear Cell Sarcoma: A Case Report and Review of the Literature.

Gastrointestinal clear cell sarcoma (GICCS)/malignant gastrointestinal neuroectodermal tumor (GNET) is an extremely rare form of cancer with aggressive clinical behavior. It has distinct pathological, immunohistochemical, ultrastructural, and molecular features. Herein, we present the case of a 20-year-old woman with no notable medical history who presented to the outpatient department with complaints of abdominal pain and vomiting. Symptoms had been evolving for 3 months. The physical examination revealed slight abdominal tenderness and melena. Biological investigations revealed iron-deficiency anemia. The upper and lower endoscopies showed no abnormalities. Magnetic resonance enterography revealed small bowel wall thickening of 15 mm × 2 mm. Exploratory laparotomy revealed an ileal mass with mesenteric lymphadenopathy. A wide resection of the mass was then performed. The final pathological report confirmed the diagnosis of small bowel GICCS/GNET. After 11 months of follow-up, the patient presented with mesenteric lymph node metastases.

Cholesterol Granuloma of the Breast Mimicking Cancer: A Case Report and Review of the Literature.

Cholesterol granuloma of the breast is an infrequent benign lesion with clinical and radiological findings suggestive of cancer. Herein, we present the case of a 52-year-old woman with no significant past medical history, who presented to the outpatient department for her routine breast screening. Physical examination revealed a painless palpable nodule in the upper external quadrant of the left breast, measuring 0.7 cm. On imaging, the mass met the criteria for Breast Imaging Reporting and Data System (BI-RADS) category 4B. Subsequently, a core needle biopsy of the mass was performed. Despite the alarming radiologic features, microscopic findings were consistent with breast cholesterol granuloma.

Cribriform-morular thyroid carcinoma: A case report with review of the literature.

Cribriform-morular thyroid carcinoma (CM-TC) is a rare entity that usually occurs in association with familial adenomatous polyposis (FAP) but may be sporadic. Herein, we present a new case of cribriform-morular thyroid carcinoma occurring in a 28-year-old woman with no history of FAP.
