Hajdu-Cheney syndrome is a rare connective tissue disorder characterized by ulcerating lesions of the palms of the hands and soles of the feet, and softening, absorption, and destruction of bones (acroosteolysis). Affected individuals may also have tiny, smooth segmented bones that are soft, moist, and warm to the touch (wormian bones); a small recessed jaw bone (mandible); a thick depression in the back of the head; and a persistent open joint between the bones of the cranium. Individuals with Hajdu-Cheney syndrome may also have loose joints (e.g., wrists and knees); webbing or fusion of the fingers and toes (syndactyly); and/or develop a condition called osteopetrosis. Osteopetrosis is characterized by a decrease in bone mass. This decrease makes an affected person susceptible to bone fractures and compression of the spine.
