Dermatological presentations of infantile myofibromatosis: a review of 27 cases.

Twenty-seven cases of infantile myofibromatosis presenting with dermatological manifestations were retrospectively reviewed. Approximately 80% were solitary lesions and 50% of these appeared on the head and neck. Around 60% were present at or soon after birth. Most lesions were dermal or subcutaneous, although some were intramuscular and intraosseous. The clinical appearance was non-specific leading to frequent misdiagnosis. While most patients presented with nodules, atrophic depressed lesions and warty pedunculated lesions were also seen. Although 7% of lesions recurred after excision, spontaneous resolution was also documented.
