Solitary Langerhans' cell granulomatosis of the stomach associated with gastric carcinoma.

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.
