Abstract

Abstract REPORT OF A CASE A 2-month-old boy had been born with a solitary nodule on his right occipitotemporal region. He was the full-term product of a 23-year-old gravida 2, para 2 woman; the pregnancy had been complicated by mild hypertension during the last eight weeks.Physical examination revealed a healthy boy with a 1.8 × 1.7-cm firm, erythematous, rubbery, slightly umbilicated nodule on the right occipitotemporal region, not attached to the underlying structures (Fig 1). A CT scan showed a normal skull and a chest roentgenogram was normal. No other abnormalities were noted. The lesion was surgically excised. Representative histologic sections are shown in Figs 2 through 4.What is your diagnosis? DIAGNOSIS: Infantile myofibromatosis (solitary type).
