Infantile digital fibromatosis is a rare benign tumor on the fingers and toes of infants and childhood which is characterized by fibroblastic proliferation.
Usually the lesions occur singly or severally on the dorsal or lateral aspects of the distal phalanges of the toes and fingers. The thumb and great toe are usually spared. There asymptomatic, firm, red, smooth nodules, some 1cm diameter, occur
during
the first vear of life. Forty-seven percent occur in the first month of life.
This disease can occur after trauma. The lesions do not metastasize. Occasionally, spontaneous regression has been reported. After excision, recurrence can be possible.
A 2 years old female infant had three large bean sized erythematous masses on the left 2,3,4th fingers. The erythematous macule was developed at 6 months old and grew slowly, We could find inclusion body stained bright red with Masson's trichrome
and
purple with PTAH in cytoplasm of fibroblast.
The patient was treated with a simple excision followed by a skin graft. During 5 months after operation, recurrence was not occurred. (Kor J Dermatol 1995;33(5) : 978~982)
