Clinical manifestations of terminal osseous dysplasia and pigmentary defects in a young girl.

Terminal osseous dysplasia and pigmentary defects is a rare X-linked dominant disorder with prenatal male lethality. Affected females display multiple systemic abnormalities such as limb deformities and pigmented lesions of the face and scalp. Phenotypic expression of the syndrome varies among the affected individuals. In this case report, we describe the syndromic dental and oral abnormalities in a female child aged 3 and 1/2 years. A widened bigonial width of the mandible and a brachyfacial pattern are observed. Intraoral findings include multiple frenulae, shallow mucobuccal fold, hypodontia, conical incisors, and other developmental structural defects.
