Terminal osseous dysplasia-pigmentary defects syndrome

Definition

A rare acromelic dysplasia characterized by abnormal and/or delayed ossification of bones primarily in the hands and feet (that may lead to brachydactyly, camptodactyly, and clinodactyly), severe limb deformities, joint contractures, pigmentary skin lesions on the face and scalp and digital fibromatosis of the fingers and toes which appear a few months after birth. While the skeletal manifestations primarily affect the hands and feet, more generalized bone involvement including mesomelic bowing and/or shortening of the arms and legs have also been reported. Some patients may also present with craniofacial dysmorphism including midface hypoplasia, hypertelorism, ptosis, coloboma of the iris and eyelids, low-set ears, depressed nasal bridge, and multiple hypertrophic frenula. Additional clinical features may include short stature, short broad thorax, scoliosis, atrial septal defect and ventricular septal hypertrophy, pulmonary artery stenosis and anal stenosis.
