Infantile Myofibroma of the Frontal Bone: A Case Report

Abstract

Infantile myofibroma stands as the most prevalent fibrous neoplasm within the pediatric population, despite its rarity. The majority of these tumors manifest within the initial 2 years of life. Clinically, myofibroma lesions are classified into solitary and multicentric tumors. We present a case of infantile myofibroma located within the frontal bone of a 16-month-old infant. Initial evaluation of the swelling and its spread was conducted using CT and MRI scans. Subsequently, the diagnosis was confirmed through a core needle biopsy. The tumor underwent surgical excision with 1 cm safety margin and immediate reconstruction with strips of calvaria bone graft. Histopathology of the specimen showed complete tumor clearance with actual margin of 7 mm. The surgical resection of cranial benign bone tumors should be meticulously planned with a multidisciplinary approach. Wherever possible, immediate reconstruction should be conducted to avoid the morbidity of a subsequent procedure.
