RESUMO

Objective: Mesenchymal in origin, solitary fibrous tumors are primarily seen within the pleura of the lung or in serosal-lined body cavities. Constituting 1% to 2% of all soft-tissue tumors, solitary fibrous tumors are rare entities, especially when found in extrapleural and in superficial locations. A review of PubMed MEDLINE literature for superficial solitary fibrous tumors revealed 71 reports in case reports and small case series. Methods: In this report, we describe a 74-year-old man with an extrapleural superficial solitary fibrous tumor, as well as present a review of the current published literature to date. Results: We present the clinical course, surgical procedure, histopathological features, and treatment options, as well as present a compilation of the published data on superficial solitary fibrous tumors. Conclusions: Based on the current literature, solitary fibrous tumors are more common in middle-aged women and in the head and neck region. Diagnosis of solitary fibrous tumors requires tissue sampling and staining for immunohistochemical markers. Management of these tumors is based on wide local excision with histologically negative margins. If negative margins cannot be surgically achieved, adjuvant therapies including radiation have been described. With extrapleural manifestations of solitary fibrous tumors seldom reported in the literature, it is our hope that reporting these unusual instances will raise awareness of such disease manifestations and allow for earlier diagnosis and treatment.
