A case report of mantle cell lymphoma manifesting as a foot lesion.

Introduction: Mantle cell lymphoma (MCL) is a rare B-cell non-Hodgkin lymphoma that most commonly affects men above the age of 60 years. The disease is called MCL because the tumor cells originate from the mantle zone of the lymph node. The most commonly affected sites are the lymph nodes, bone marrow, gastrointestinal tract, Waldeyer's ring and rarely the skin, breast and central nervous system.

Pediatric orbital hemangiopericytoma associated with trisomy 15.

We report a case of an orbital hemangiopericytoma (HPC) in a female infant diagnosed at 7 weeks of age. Cytogenetic analysis of the tumor revealed trisomy 15. To the authors' knowledge, this is only the second reported case of this chromosomal aberration being associated with HPC, both cases occurring in infants.

Giant cell tumor of bone with secondary aneurysmal bone cyst-like change producing β-human chorionic gonadotropin.

Giant cell tumor of bone is a benign, locally aggressive neoplasm that is composed of sheets of neoplastic mononuclear cells interspersed amongst non-neoplastic, uniformly distributed, osteoclast-like giant cells. They represent approximately 4-5% of primary bone tumors. Rarely, bone tumors have been noted to produce human chorionic gonadotropin, a finding most often reported in osteosarcoma.

Pseudoangiomatous stromal hyperplasia of the vulva presenting as a polypoid vulvar lesion: a lesion associated with anogenital mammary-like tissue-report of a case and review of the literature.

Objective: The study aimed to report the case of a patient with a polypoid vulvar lesion clinically thought to be an aggressive angiomyxoma.
