Inguinal Solitary Fibrous Tumor: A Case Report.

INTRODUCTION

A solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm that may occur in a wide range of sites, more commonly in the pleura. We report a well-documented case of an SFT with malignant histology arising in the inguinal region.

CASE PRESENTATION

A 59-year-old man, with an unremarkable medical history, presented with a slow-growing painless mass in the left side of the inguinal region, which he had ignored for 3 years. On clinical examination, there was an indurated, irreducible, mobile, and painless mass in the left side of the inguinal area. Magnetic resonance imaging and computed tomography results revealed a 15-cm mass made up of soft tissue and with nonspecific radiologic aspect. The tumor was totally excised, and the results of the pathologic examination concluded it was an SFT.

DISCUSSION

The aim of our case report is to present a rare extrapleural localization of an SFT. Although its radiologic features are not specific, SFT should be considered in the differential diagnosis of inguinal masses.
