Abstract

The Fusiform cell Lipoma is a rare entity of benign adipose tumors. Characterized by the presence of fusiform cells forming collagen, and can be confused with the fusocellular component Liposarcoma.

We report the case of a patient aged 46 years supported in our formation for a subcutaneous mass of the infero-internal region of the left thigh, whose appearance at ultrasound and MRI evokes at first a Liposarcoma. It is the histological and immuno-Histochemical examination that allows the confirmation of the diagnosis.

Introduction

Fusiform cell Lipoma is a rare entity of benign fat tumors [1]. Characterized by the presence of fusiform cells forming collagen [2,3], and can be confused with fusocellular component Liposarcoma [4,5], affecting mainly the young male between 45 years and 65 years, with preferential seat under posterior neck and shoulder area and 13% atypical localization [6].

Here we report the case of a patient supported in our formation for Lipoma with fusiform cells of the left thigh.

Case Presentation

It is a patient of 46 years without significant pathological history, who consults for a subcutaneous swelling of the infero-internal region of the left thigh, progressive onset and evolving for 6 months; it is a painless mass with firm consistency, movable in relation to the skin plane and adherent to the deep plane, of 8 cm of large axis. The patient benefited from an ultrasound that showed a very limited, subcutaneous ovalar formation with regular contours, of a heterogeneous tissue echostructure, respecting the adjacent muscular plane, simulating a Liposarcoma. MRI has objectified the presence of a superficial mass, measuring 50 × 43 × 21, very limited, with regular contours, in hypo signal T1et hyper signal T2; with T1 and T2 hypersignal zones. This mass is increased after injection of gadolinium, without muscular, bone or ligamentous lesions. First evoking a Liposarcoma (Figure 1,2). A surgical biopsy was performed whose anatomopathological result was in favor of a fusiform cell Lipoma. The patient has benefited a surgical resection of the tumor mass.
