[Transformation of Follicular Lymphoma into Composite Lymphoma: A Case Report and Literature Review].

Follicular lymphoma is a relatively indolent B-cell lymphoma composed of neoplastic centrocytes and centroblasts. The histologic transformation of follicular lymphoma is a well-described phenomenon with an average risk of 30% at ten years. The occurrence of Hodgkin lymphoma after follicular lymphoma, as well as composite lymphoma, is extremely rare.

An unusual case of small bowel volvulus due to pneumatosis cystoides intestinalis: Case report and literature review.

Introduction And Importance: Pneumatosis cystoides intestinalis (PCI) is an uncommon condition characterized by intramural gas accumulation in the intestinal submucosa. Idiopathic or secondary is presented with non-specific clinical signs; in some cases, diagnosis is incidental. Its acute presentation is uncommon, and surgical management could be performed in selected cases.

[Primary testicular NK/T cell lymphoma. Case report and review of literature].

Natural killer/T cell lymphomas chiefly involving the midline facial structures including the nasal cavity or nasopharyns are a relatively rare type of non-Hodgkin's lymphoma. Apart from the upper respiratory tract, the disease occasionally presents in certain extranodal sites, such as the central nervous system, skin, gastrointestinal tract, or testes. We report a case of natural killer NK/T cell lymphoma as a testicular tumor in a 36-year-old man with a history of progressive swelling of his right testicle.
