Benign Symmetric Lipomatosis: A Patient Report

Benign symmetric lipomatosis (BSL) is a disease characterized by symmetrical and diffuse adipose tissue deposits on the neck, shoulder, chest, abdomen and groin. It is comparatively common in the Mediterranean basin, but rare in Japan. We report on a 53-year-old male patient with BSL along with a review of the literature. The lesions were distributed bilaterally in the submandibular, neck and upper back region. This patient had consumed an excessive amount of alcohol with elevated liver enzymes including aspartate aminotransferase (133 IU/L), alanine aminotransferase (159 IU/L) and gamma-glutamyl transpeptidase (355 IU/L). The liver function was normalized after a 1-year restriction of alcohol consumption through life management. Tumors in the posterior and anterior cervical regions were resected. The patient is still in a good condition at 3 years and 5 months after the operation.
