title: Tarsal dermoid cyst: clinical presentation and treatment.
abstract: The authors present 2 cases of eyelid dermoid cyst attached to tarsus in pediatric patients. Both patients were infants who presented with a firm, nontender upper eyelid mass firmly adherent to tarsus. In both cases, the lesion was excised en bloc, and histopathology revealed a dermoid cyst. To the authors' knowledge, there are no previously reported cases of tarsal dermoid cyst. These cases demonstrate the importance of including dermoid cyst in the differential diagnosis of a tarsus-based eyelid mass. Misdiagnosis may lead to incision and curettage, resulting in spillage of cyst contents and the risk of severe inflammation and scarring.
