Sclerosing extramedullary hematopoietic tumor (SEMHT) is a rare lesion and presented as retroperitoneal or serosal-based mass. A 53-year-old man with a long history of primary myelofibrosis, presented with abdominal distension and inguinal mass. Pathologic examination of inguinal mass revealed a prominent sclerotic background with thick collagen deposits and mono, bi, or tri-lineage hematopoiet...

Intranodal palisaded myofibroblastoma is a rare lymph node benign tumor, of unknown pathogenesis. Although benign, this lesion is frequently confused with metastatic lesions, especially in atypical sites. We report a 39-year-old man with a history of testicular malignant mixed germ cell tumor, presented with abdominal painless mass. The computed tomography of the abdomen confirmed the presence ...

CONTEXT Paragangliomas are rare tumours of neural crest origin. Extra-adrenal pancreatic paragangliomas are exceptionally rare. CASE REPORT A 66-year-old man with abdominal pain was noted to have a complex pancreatic head and uncinate process mass on imaging. He underwent complete resection by pancreaticoduodenectomy with final pathology confirming a 6 cm paraganglioma without evidence of met...

BACKGROUND The study of neoplasia in wildlife species contributes to the understanding of cancer biology, management practices, and comparative pathology. Higher frequencies of neoplasms among captive non-domestic felids have been reported most commonly in aging individuals. However, testicular tumours have rarely been reported. This report describes a metastatic testicular sex cord-stromal tum...

A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion. During surgery, a mass was observed only in the left ovary with no invasive growth, but ...

Primary adrenal leiomyosarcoma has been reported previously in 25 patients. The patient presented herein is the only case where the definitive diagnosis was made with core needle biopsy evaluation. A 45-year-old male presented with pain in the back and right groin. Radiological evaluation demonstrated a heterogeneous 11 cm right adrenal mass, multiple liver masses, and an enlarged aortocaval ly...

Lymphangioma is a benign form of neoplasm arising from the lymphatic system. It occurs as a result of congenital malformations of the lymphatics leading to the obstruction of local lymph flow and the development of lymphangiectasia. Lymphangiomas are common in pediatric patients, in the soft tissues of the neck and the axillae, but lymphangioma of the pancreas is extremely rare, accounting for ...

Rhabdomyosarcoma (RMS) is a soft tissue neoplasm of mesenchymal origin. It is a commonly encountered malignant tumor amongst pediatric patients, yet relatively rare in adults. It usually involves the head and neck region, genitourinary organs and retroperitoneal structures. In adults, the most commonly affected area is the head and neck region. We present here a case of a 30-year-old male patie...

KHE: kaposiform hemangioendothelioma KMP: Kasabach-Merritt phenomenon INTRODUCTION Kaposiform hemangioendothelioma (KHE) was first described by Zuckerberg et al in 1992. KHE is defined as a rare, locally aggressive infiltrative vascular neoplasm that typically occurs during infancy and childhood. KHE generally originates on the skin as a distinctive cutaneous lesion with ill-defined borders, la...
