ABSTRACT

Background: Liposarcomas are a type of soft tissue tumor. The dedifferentiated subtype is one of the most common variants along with well-differentiated liposarcoma.
Clinical case: A 68-year-old female patient presented for consultation due to the appearance of a mass in the vaginal area which was clinically diagnosed as a direct inguinal hernia. Surgical resection of the mass was performed. The histopathological report was myofibrolipoma, without atypia and with borders free of neoplasia. Three years later, the patient returned to the office for recurrence of the mass and refused a new biopsy. Subsequently, in 2020, the patient accepted the resection of the mass; the histopathologic report was: dedifferentiated liposarcoma with lipoblastic differentiation homologous to pleomorphic liposarcoma.
Conclusion: Histopathological studies are necessary for confirmation of the diagnosis and surgical resection is the treatment of choice.
