Abstract
Background:The incidence of extraorbital giant cell angiofibroma (GCA) is rare, with only one case located in the scalp reported in the literature. The morphological hallmark is histopathological examination showing richly vascularized pattern-less spindle cell proliferation containing pseudovascular spaces and floret-like multinucleate giant cells.Case Description:We report a case of a 30-year-old female with a primary complaint of a painless solitary nodule arising on the left parietal region of the scalp. Complete tumor removal through surgical intervention was achieved, and the postoperative period was uneventful.Conclusion:Diagnosing a highly vascularized tumor in the head and neck is challenging. Our case is unique in that it is presented as a GCA of the scalp, which is an extremely rare clinical entity, and also demonstrated bone destruction.
Highlights
The incidence of extraorbital giant cell angiofibroma (GCA) is rare, with only one case located in the scalp reported in the literature
Approximately 39 cases have been reported in the literature. Most of these lesions involve the orbital region, and it predominates in males; females predominantly present GCA at extraorbital sites, including the nasolacrimal duct, buccal mucosa, submandibular region, trunk, mediastinum, retroperitoneum, vulva, and extremities.[2,8]
GCA may belong to a solitary fibrous tumor (SFT)
Summary
Diagnosing a highly vascularized tumor in the head and neck is challenging. Our case is unique in that it is presented as a GCA of the scalp, which is an extremely rare clinical entity, and demonstrated bone destruction. Giant cell angiofibroma (GCA) is a nonrecurring benign neoplasm that was first described in 1995 in a study of seven patients with a distinctive orbital tumor.[2] Since approximately 39 cases have been reported in the literature. Group, as it contains multinucleated giant stromal cells and angiectoid space.[14] GCA may grow rapidly and stimulate an aggressive or malignant process It may have an indolent course; it sometimes presents as a painful mass that grows slowly or remains stable in size over many years.[5,8]. A 30‐year‐old female presented with a bony swelling over her left parietal region that had increased in size over the past 2 years She had no history of trauma, bone pain, systemic disease, or neurological symptoms. She was discharged from the hospital uneventfully, and no recurrence of the mass was detected at her one‐year follow‐up
