@mattypowz.md: Hey doc, what’s this painful bump? 🚨 The answer is… A) pilar cyst, confirmed on biopsy. Inflammation can make a benign cyst look concerning, and a tender, keratotic bump can also raise suspicion for skin cancers. Pilar cysts are benign cysts that develop from the outer sheath of a hair follicle and fill with keratin. They commonly occur on the scalp and can run in families. If bothersome, they can be surgically removed along with the cyst wall to reduce recurrence. A painful bump isn’t automatically cancer, but a new, growing or changing lesion deserves an in person assessment. For education only. Patient consent obtained. #skincancerawareness #cyst #acne
