ABSTRACT
Intramuscular lipoma is a rare, benign uncapsulated tumor. It is also called infiltrating lipoma because of its infiltrative growth pattern which, deeply localized, seizes the skeletal muscle. The only obvious symptom is a palpable mass. Microscopically, fat tissue shows up between the muscle fibers. We report a case of intramuscular lipoma. The patient, a 60-year-old man, developed a nut-sized, painless, skin-colored tumor on the forehead. Laboratory studies were negative or within the normal range. Histopathological findings showed mature lipocytes infiltrate muscle in diffuse manner. The lesion had been excised completely and showed no evidence of recurrence.

A basal cell carcinoma developed in the forehead of a 57-year-old man at the scar site from a blunt trauma that happened 10 months previously. The patient had never been noted to have premalignant or other malignant skin lesions. The significance of injury in the etiology of basal cell carcinoma is discussed.
