Four BSL cases had been reported in Japan, all of which had been found in the posterior neck. This report presents an atypical case of BSL manifested in the tongue.<BR>A lipoma-like tumor was observed in the bilateral borders of the tongue. The laboratory data were almost normal. He had suffered from apoplexy and alcoholism. A lingual biopsy was performed, and a diagnosis of BSL was made in terms of both the clinical and histological findings.<BR>The discussion includes the clinical findings of BSL and differential diagnosis between lipomatosis and lipoma. Especially the differences of macro-and microscopic findings between lipomatosis and lipoma are emphasized.
