title: Solitary bone cyst with epiphyseal involvement: a case report.
abstract: A large solitary bone cyst involving the epiphysis produced 5.0 cm shortening of the proximal humerus in a 15-year-old girl. Biopsy revealed the cyst was filled with thin yellow fluid under pressure and lined by a fibrous membrane. X-rays 9 months after biopsy demonstrated progressive cyst obliteration. A review of literature revealed no similar case. It is postulated that solitary cysts rarely may involve the physeal and epiphyseal structures and thereby retard longitudinal bone growth.
