Swelling of the temporal region: a case of benign masticatory muscle hypertrophy.
A 35-year-old Caucasian woman had bilateral indolent swelling of the temporal regions. Imaging studies with nuclear magnetic resonance, ultrasonography and histopathological investigation revealed enlargement of the temporal and masseter muscles, with no pathology in the skin or subcutaneous tissue. A small prolactinoma of the pituitary gland was incidentally found. The condition, designated benign masticatory muscle hypertrophy, should be distinguished from similar diseases affecting the skin and the subcutaneous tissue of the scalp. The cause remains unknown.
