Abstract
Sclerosing epithelioid fibrosarcoma (SEF) is a rare mesenchymal tumor.
SEF appears to be a slowly growing tumor often present for several months or years before diagnosis.
A tumor of the gluteal region may mimic a sciatic nerve pain.
SEF has a poor prognosis with high risk of metastasis.
The treatment is surgical.
Introduction and importance
Sclerosing epithelioid fibrosarcoma (SEF) is a rare variant of low grade fibrosarcoma, with specific histological and immunohistochemical features. SEF is a difficult to diagnose. The prognosis is poor with a 40% mortality rate.
Case presentation
We report a case of 45-year-old female patient who presented to our department with a history of right sciatalgia evolving for three months. On physical examination, a firmly not well-defined mass was found in the right gluteal region. The histological diagnosis revealed a SEF.
Clinical discussion
SEF appears to be a slowly growing tumor often present for several months or years before diagnosis. The 3-month delay of our diagnosis shows the difficulty arising from the inconclusive clinical of this tumor.
Conclusion
SEF of the gluteal region can induce sciatalgia. The diagnosis should be made as early as possible in order to improve the prognosis.
