History: Infantile digital fibromatosis is a distinctive benign fibrous tumour of infancy. It usually presents in the first year of life and occurs exclusively in the fingers and toes but spares the thumbs and great toes. Single or multiple small nodules (less than 2 cm) are found on the sides or dorsum of the interphalangeal joints. Histologically the lesion is characterised by an inclusion body within the cytoplasm. Radiographic examination reveals a noncalcified soft tissue mass. There is often phalangeal dysplasia but rarely bone erosion. Spontaneous regression without surgery has been reported. It has therefore been suggested that surgery should be delayed unless function is compromised. Following surgery 60% of cases recur locally but the final prognosis is excellent
