D17: Benign lipomatous neoplasm

Benign lipomatous neoplasms, often simply called lipomas, are a group of conditions characterized by the growth of benign (non-cancerous) fat tissue tumors. These growths can occur virtually anywhere in the body where fat cells exist, but are most commonly found under the skin in areas like the back, arms, and thighs. Typically, lipomas are soft to touch, painless, and slow-growing. They often present as palpable lumps beneath the skin, with sizes that can range from a small pea to a large grapefruit. The precise causes of lipomas are not entirely understood, but they appear to have a hereditary link and can sometimes be associated with certain genetic conditions like familial multiple lipomatosis. While benign, they might cause discomfort or distress if they interfere with function or have an aesthetically displeasing appearance. It's important to remember that while these growths are generally harmless, any new, growing, or changing lump should be evaluated by a medical professional to rule out more serious conditions.
