Clinically, folliculosebaceous cystic hamartoma (FSCH) lacks distinct features, but it has been reported as an asymptomatic, 1- to 3-cm, dome-shaped nodule on the face. Histopathologically, FSCH is characterized by adnexal and folliculosebaceous cystic proliferation with various mesenchymal changes. This case presented an unusually large, small-fist-sized mass in the right mandibular area that was accompanied by intermittent itching. Histopathologic findings demonstrated appropriate features of FSCH. We present an interesting case of giant FSCH in a 48-year-old female.
