Recurring digital fibroma of infancy.

CASE REPORTS Case 1-A boy aged six months was seen in 1969 because of a swelling on the back of the distal part of the right middle finger. He was the fourth child of healthy parents. The tumour had appeared in the third month of life ; it was about 5 millimetres in diameter, firm, not tender, and fixed to the skin but not to the underlying tissues. Biopsy showed a dermatofibroma with no sign of malignancy. The tumour then started to grow more rapidly, and it was decided to excise it completely and apply a skin graft. Three months later a recurrence was excised. After three more months a second recurrence had occurred and the parents refused further operations. Now after four years this has disappeared and only a small local thickening is evident on the lateral aspect of the finger where the graft meets normal skin.
