A patient suffering from brucellosis developed maculonodular and purpuric lesions. The skin biopsy showed granulomatous vasculitis with no deposition of immunoglobulins and complement on the vessels.

A case of Langerhans' cell granulomatosis associated with gastric adenocarcinoma is reported. A review of the literature demonstrate an association of this entity with Hodgkin or non-Hodgkin lymphomas alone. The discussion is centred on differential diagnosis from the pseudo-sarcoid granulomatous reaction. Further reports may assist in classifying the granulomatous reaction to tumours into two types, epithelioid and Langerhans.

Presentamos el caso de un varón de 42 años que acude a nuestro Hospital por cuadros recurrentes de anemia ferropénica. Los estudios endoscópicos y radiológicos no evidenciaron el origen de la anemia. La angiografía detectó lesiones compatibles con angiodisplasia. Se practicó hemicolectomía derecha confirmándose el diagnóstico en el estudio anatomo-patológico.
