Recurring infantile digital fibromatosis: report of two cases.

There have been 100 reported cases resembling this rare entity. This type of fibroma differs from others in three respects: (1) clinically it is limited to the fingers and toes in infants, (2) it has a remarkable tendency to recur, and (3) morphologically it is characterized by the presence of cytoplasmic inclusion bodies. Herein the authors discuss two cases. This type of fibroma appears from birth to age 3 years in the digits; if correctly diagnosed and left alone, it will regress spontaneously. On the basis of the literature, the present cases were treated conservatively and had follow-up until the fibromas disappeared and did not recur.
