Abstract

Extraskeletal osteosarcoma (EOS) is a high-grade malignant tumor that accounts for less than 2% of soft tissue sarcomas and mainly engages people between the fifth and sixth decade of life. It is typically of late diagnosis, with an extensive symptomdiagnosis period greater than 6 months compared to conventional osteosarcoma. We report the case of a 43-year-old patient who presented in our service with a 1-year-old tumor localized in the gluteal and left thigh region. After inconclusive paraclinical studies and biopsy, the tumor was surgically resected with wide margins and diagnosed as EOS after the histological analysis of the piece. The patient showed a very good clinical and paraclinical progression without signs of local or distant recurrence after 20 months of follow-up.
