ABSTRACT
Rosai-Dorfman disease (RDD) is a rare benign proliferative histiocytic disorder characterised by massive lymphadenopathy. While extranodal involvement can occur in generalised RDD, isolated soft tissue RDD (STRDD) is extremely rare. We report a 17-year-old male patient who presented to the maxillofacial outpatient department of the Sultan Qaboos Hospital, Salalah, Oman, in 2015 with a painless cheek mass which had been slowly growing over the previous two months. Routine histopathological examinations and immunohistochemistry confirmed a diagnosis of STRDD. Currently, surgical excision is considered to be the most effective curative treatment for STRDD, as the outcomes of other treatment modalities are still unknown. Despite its rarity, STRDD should be considered in the differential diagnosis of histiocytic soft tissue lesions.

CONTEXT: Heterotopic pancreas is the presence of pancreatic tissue found outside the usual anatomical location of the pancreas. It is a rare condition and can occur anywhere in the gastrointestinal tract with the stomach and the small bowel being the most common sites. It is usually asymptomatic and often discovered incidentally. CASE REPORT: We report the case of a 48-year-old Omani female who presented with recurrent epigastric pain. Endoscopy revealed a sessile mass in the antrum which was snared and showed heterotopic pancreatic tissue in the submucosa on histopathology. CONCLUSION: Heterotopic pancreas should be considered in the differential diagnosis of gastric mass lesions.

Lymphoepithelioid cell lymphoma Lennert's Lymphoma is a rare morphological variant of peripheral T-cell lymphoma characterized by the presence of numerous clusters of epithelioid histiocytes without formation of discrete granulomas and the intervening atypical lymphocytes. Lennert's lymphoma is often misinterpreted as granulomatous lymphadenitis or Hodgkin's disease. This report describes fine needle aspiration cytology and histological findings in a case of Lennert's lymphoma.

A case of myofibroblastoma of the breast was recently diagnosed in an adolescent Omani boy. In this report, the clinical, histopathological and the radiological features of this rare disease are being discussed. We conclude that, myofibroblastoma of the breast, which was earlier described, predominantly, in elderlies, can occur in people from any age group.
