Popis: Myofibroma, the most common juvenile fibrous disorder in infancy, usually manifests as a solitary soft tissue tumor and less commonly as simultaneous multiple tumors in both soft tissue and bones. Infantile myofibromatosis is well described in the head and neck, but cutaneous lesions rarely occur in the periorbit and orbit, where fast growth and bone damage can mimic malignant tumors. We describe a case of a solitary periorbital myofibroma in a newborn. Treatment consisted of partial excision of the tumor. Histologic and immunohistochemistry analyses provided the diagnosis of infantile myofibromatosis. The patient remains disease-free at 10 years of age, but with some visual impairment. Infantile myofibromatosis is an uncommon tumor with exceptional periorbital involvement. Differential diagnosis can be difficult when it is solely based on histologic assessment. Immunohistochemistry evaluation demonstrating cytoplasmic actin filaments in neoplastic spindle cells confirms the diagnosis. As soon as the diagnosis is made, chest and abdominal imaging must be performed to evaluate the overall prognosis and direct treatment. The treatment of choice is early conservative surgery to minimize functional and/or esthetic damage. Complete tumor excision is not always possible. Lengthy ophthalmologic monitoring is required to detect the onset of amblyopia.
