Infantile myofibromatosis presenting with scalp dermoid cyst.
Infantile myofibromatosis is a disorder of infancy and early childhood, typically presenting as a solitary lesion or multiple widespread nodular tumors localized to skin, subcutaneous tissue, muscle, bone, viscera, or central nervous system. We present a case of infantile myofibromatosis, multicentric type, in a 4-month-old male infant who initially presented with an occipital scalp mass and other skin-colored nodular mass lesions over his face, trunk, and four limbs. He received tissue biopsy to establish a definite diagnosis. Craniotomy was also arranged for tumor removal due to dural involvement with internal extension and compression of adjacent sigmoid sinus. The patient eventually died of cardiopulmonary failure secondary to primary pulmonary hypertension at age 11 months. Before his death, he had suffered from abdominal distention and frequent vomiting, followed by aggravated respiratory distress and cyanosis. Aggressive surveillance for cardiopulmonary or gastrointestinal involvement is recommended in such cases because prognosis varies according to the involvement of vital organs.
