Abstract This 5-year-old girl was referred to an orthopedic surgeon because of pain in her left wrist for a period of weeks. Three months previously, she had hurt the dorsum of her left hand and wrist in a fall. The lateral aspect of the dorsum of the hand was swollen. A roentgenogram of the left hand was obtained (Fig 1 and 2). A chest roentgenogram was normal. Skin tests for microbacterial and fungal causes were negative. A complete blood cell count was normal. The carpal lesion underwent biopsy and was partially resected. Denouement and Discussion Juvenile Aponeurotic Fibroma Microscopie examination of sections of the lesion (Fig 3 and 4) showed degenerating focally hyalinized fibrocartilagenous tissue and fragments of proliferating fibroblastic cells arranged in nodules, palisading or intertwining tangles of eosinophilic spindle-shaped cells. Nuclei were oval or spindle shaped, moderately hyperchromatic, and uniform in size. Several islands of cartilagenous metaplasia with focal calcification were present References 1.
