The biopsy specimen revealed an intradermal benign neoplasm composed of spindle cells with blunt, vesicular nuclei arranged in interweaving fascicles. There were characteristic intracytoplasmic eosinophilic globules measuring approximately 5 to 9 µm in diameter.
The clinical and histologic findings led to a diagnosis of recurrent infantile digital fibromatosis. After being informed of the benign nature of these lesions, the patient's mother preferred conservative treatment with observation only.
