RESUMEN
BACKGROUND: Pure heterologous sarcomas of the uterine corpus are extremely rare, accounting for 4% of all uterine sarcomas. Primary chondrosarcoma, which is characterized by the absence of epithelial or other heterologous mesenchymal elements, is included in this group. To this date, only 17 cases, including the presenting case, have been reported. CASE: A 55-year-old female presenting with post-menopausal bleeding was diagnosed with chondrosarcoma of the uterus, after abdominal hysterectomy and bilateral salpingoophorectomy. After 8 months of surgery, there is no evidence of recurrence after receiving external radiotherapy and brachytherapy. CONCLUSION: Primary chondrosarcoma of the uterus is an extremely rare uterine tumour most frequently diagnosed by the pathologist. They are usually aggressive malignant tumours with an early relapse and metastases.
