Excision of a bump, was unsure of the diagnosis during surgery

I was unsure exactly what this was and sent her tissue out to confirm that this is a Pilomatricoma (aka Calcifying Epithelioma of Malherbe, or pilomatrixoma) is a benign growth derived from hair matrix cells. Usually occurs as a single lesion on the face, neck or upper arms. They cause no pain, but are firm bumps under the skin. The diagnosis is usually made only after looking at the tissue under the microscope. We look for “shadow cells” under the microscope. Calcification and ossification can occur (calcium and bone can develop within) which can make these very firm and hard, much like a pebble or little jagged rock under the skin. These are benign and don’t need to be removed, but if someone requests removal, a surgical excision is needed.
