A Case of Angiomatoid Fibrous Histiocytoma of Soft Tissue / 대한피부과학회지

ABSTRACT

Fibrous histiocytoma is a common benign tumor which occurs usually in the dermis. It can be classified as fibrous type, cellular type, mixed type and angiomatoid type, depending on its major cellular components. Angiomatoid fibrous histiocytoma is a rare subtype, showing characteristic hemorrhagic cyst. Fibrous histiocytoma arises rarely in deep soft tissues such as fascia, muscle or periosteum, and shows clinical and histopathological characteristics somewhat different from the cutaneous histiocytoma. We report a case of angiomatoid fibrous histiocytoma of deep location which arose in the galea of scalp in a 7-year-old boy, who had a tender slightly fixed deep seated nodule, measuring 0.5 cm, for 5 months.
