Lipoma : Clinical Features
Clinical Features: Most lipomas present between 4th and 6th decades of life with a male predilection. They are uncommon in children and young adults. Lipomas may be solitary (most common) or multiple. Multiple lipomas are more common in men and may occur in familial setting. Once formed, they don't regress. Superficial lipomas usually present as slow-growing, asymptomatic, painless, round or oval masses with a soft consistency. Angiolipomas or lipomas that compress peripheral nerves can produce pain. Large tumors may be cosmetically disfiguring (as seen in this case). Deep lipomas, based on their location and size, can cause abdominal fullness, discomfort, dyspnea or palpitation (mediastinal tumors). Lipomas arising near juxtaarticular region or periosteum can produce nerve compression, bone erosion and movement restriction. This photograph shows a giant, disfiguring, superficial lipoma on the upper back of a 65 y/o male. It was slow growing and had attained a size of 30 x 20 x 15 cm over the course of 20+ years. Microscopic examination showed a typical lipoma. Image courtesy of: Dr. Sanjay D. Deshmukh, Professor of Pathology, Dr. Vithalrao Vikhe Patil Medical College & Hospital, Ahmednagar, India.
