title: Malignant angioendotheliomatosis (Angiotropic lymphoma) of the gallbladder.
abstract: We present a case of malignant angioendotheliomatosis of the gallbladder, the first reported. Diagnostic problems connected with this rare malignancy are underlined. Immunohistochemical studies were useful in providing further evidence of the lymphoid nature of the neoplasm and avoiding possible misdiagnosis. We suggest that the term "angiotropic lymphoma" might be more appropriate to define this malignancy.
