Mullerian adenosarcoma (MA) of ovary with sarcomatous (rhabdomyoblastic) overgrowth is an extremely rare malignant type of female genital tract neoplasm. These tumours are highly aggressive and presence of heterologous elements is associated with worse prognosis. A 44 year old female presented with lower abdominal pain and distension. She had history of removal of tumour from pouch of Douglas in 2006 for which she did not receive any additional treatment nor did she keep continuous follow up. Current preoperative radiological examination revealed bilateral ovarian masses. She underwent abdominal hysterectomy with bilateral oophorectomy. Microscopic examination revealed biphasic tumours exhibiting sarcomatous overgrowth with rhabdomyoblastic differentiation. Review of the previous biopsy revealed low grade Mullerian adenosarcoma without sarcomatous overgrowth. Hence the current tumour was considered recurrent. This report highlights the aggressive nature of MA even with low grade morphological features and emphasizes the importance of continuous follow up and additional treatment
