A CASE REPORT OF CALCIFYING APONEUROTIC FIBROMA IN AN 11-YEAR-OLD BOY

In this case report we present an 11-year-old boy with a history of trauma to distal phalanx of the forth finger of his left hand from three years ago. This trauma led to a lesion which was resistant to antibiotic therapy. Underline bone and nail of finger have been destructed by tumor. Microscopic examination revealed plump spindle cells arranged in sheets with paralleled orientation and foci of calcification. Final diagnosis was calcified aponeurotic fibroma, a very rare tumor of soft tissue which has been reported only in few cases since its discovery. Additionally, clinical presentation of tumor in this case is also very rare.
