Cytopathologic aspects of a metastatic malignant mixed Müllerian tumor of the uterus. Report of a case with transabdominal fine needle aspiration biopsy.

The cytologic details of a fine needle aspiration biopsy of an intraabdominal metastatic malignant mixed Müllerian tumor of the uterine corpus are presented. Cytologically, the malignant stromal and epithelial elements resembled those in previous histologic materials. Given the aggressive nature of this lesion, the patient may initially present with an inoperable tumor; cytologic examination of an aspiration biopsy may be diagnostic without the need for an exploratory laparotomy.
