[A primary malignant lymphoma of the appendix]

Abstract

A malignant lymphoma (ML) of the gastrointestinal tract occurs most frequently in the stomach, and ML of the appendix is very rare, with only 16 cases reported in the Japanese literature. Reported is a case of a primary ML the appendix in a 48 year old male, in whom an ileocecal resection was carried out. This case was pathohistologically diagnosed as a diffuse large lymphoma of the B cell type, according to the LSG classification. Therapeutic problems were encountered because of the difficulty in making an early diagnosis.
