외상에 의해 유발된 보행장애를 동반한 석회화 건막 섬유종

Abstract

A calcifying aponeurotic fibroma is a rare benign fibrous tumor with well-characterized histopathological features. Calcifying aponeurotic fibromas are generally slowly-growing lesions related to tendons and aponeuroses in the distal extremities of children and adolescents. While the neoplasm is usually asymptomatic, cases of progressive local discomfort have been reported. The exact etiology of this neoplasm is unknown, and there is frequently no history of trauma or local irritating factors. A 10-year-old female presented with a 2.5×2.0 cm, subcutaneous mass on the right sole 4 years after she bumped against a table. The histopathologic examination showed a poorly circumscribed fibrotic mass with foci of chondroid differentiation and calcification. These findings were consistent with the diagnosis of a calcifying aponeurotic fibroma. After total excision of the mass, there has been no recurrence of the lesion in 8 months of follow-up.
