ABSTRACT
Introduction:
Infantile digital fibromatosis, also known as Reye tumor, is a rare, asymptomatic, benign nodular proliferation of fibrous tissue, which occurs almost exclusively in the dorsolateral region of the fingers and toes. This article reports a case of infantile digital fibromatosis.
Case report:
This case was diagnosed by clinical, imaging, and histopathological examination. The patient presented at the Orthopedic Department of our hospital, with a 4-year history of a painless, erythematous nodular lesion on the second toe of the left foot. On physical examination, a deformity of the second toe caused by a nodular, erythematous, painless lesion of approximately 1.5 cm diameter was noted; the lesion did not result in functional changes. Ultrasound examination revealed a solid, hypoechoic nodule involving the extensor tendon in the middle phalanx of the second toe. The initial diagnosis was fibroma or synovioma. Due to the clinical characteristics of the lesion, its evolution, and the imaging findings, the team chose to perform a biopsy. However, due to the small size of the lesion, upon open biopsy, surgical excision was performed. Histopathological examination confirmed the diagnosis of infantile digital fibromatosis.
Conclusion:
Infantile digital fibromatosis is a rare clinical entity, which should be differentiated from other lesions found in the fingers and toes. The correct diagnosis is rarely made preoperatively, due mainly to a failure to recognize this entity. For this reason, it is essential to onsider this lesion in the differential diagnosis of digital nodules.
