Aggressively recurrent infantile myofibroma of the axilla and shoulder girdle.
Infantile myofibroma is the most common fibrous tumor of infancy, typically affecting neonates and children under 2 years of age. Though the multicentric variant portends a grave prognosis, solitary lesions have an excellent prognosis and frequently undergo spontaneous regression. Surgical excision of solitary lesions is usually curative. In this report, we describe a pediatric patient with an unusually aggressive solitary myofibroma of the axilla who ultimately required a forequarter amputation as a lifesaving measure following multiple tumor recurrences and progressive tumor growth. The clinical course, radiographic findings, histology, and management rationale are presented.
