Soft tissue rosai-dorfman disease case report

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

Bilateral pregnancy luteoma: a case report

Pregnancy luteoma is a non-neoplastic lesion of the ovary occurring during pregnancy and is usually discovered incidentally at the time of a cesarean section or during postpartum tubal ligation. An accurate diagnosis is important for the mother and the fetus as it can be confused with ovarian malignancy leading to unnecessary surgery. We report a case of a pregnant female who was discovered to have bilateral enlarged ovaries at the time of emergency cesarean section

Large Brunner's gland hamartoma: a case report

Brunner's gland hamartoma is an extremely uncommon benign tumor of the duodenum. Most of the lesions are small, asymptomatic and are detected incidentally. It may rarely attain a large size and produces a variety of clinical manifestations. Imaging modalities and endoscopy may locate the lesion, but definitive diagnosis requires histopathological examination. We report a case of a 58-year-old Omani female who presented with obstruction due to a large Brunner's gland hamartoma

Chondroid lipoma: a case report

Chondroid lipoma is a unique, uncommon benign lipomatous tumour. Due to distinct morphological simily, it is important to distinguish it from extraskeletal chondrosarcoma and myxoid/round cell liposarcoma [MRCLS]. We report such a neoplasm with brief a review of literature

Lennert's Lymphoma

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

Primary amelanotic melanoma of tongue. a case report

We report a case of primary amelanotic melanoma in a twenty-four year old Omani male patient who presented with a swelling of the tongue of one year and two months' duration. Malignant melanoma, especially the amelanotic type, is a very rare tumor of the oral cavity and tongue
