Rhabdomyoma of the Lip: A Case Report With Review of the Literature.
Rhabdomyoma (RM) is a rare benign mesenchymal tumor associated with skeletal muscle differentiation. We report a case of adult-type RM occurring in the lower lip of a 48-year-old man, clinically suspicious for squamous cell carcinoma. Only 3 cases of adult-type RM have been described in the literature in this anatomical site. The histologic differential diagnoses with other lesions are presented, with emphasis on immunohistochemical aspects.
