Abstract

Uterine mesenchymal neoplasms are generally divided into smooth muscle tumors, endometrial stromal tumors, perivascular epithelioid cell tumors, and other mesenchymal tumors of both homologous and heterologous tissue types. In addition, tumors with mixed epithelial and mesenchymal components are also included in this chapter. While benign leiomyomas are very common, uterine leiomyosarcoma and endometrial stromal tumors are rare, frequently unexpected lesions at the time of frozen section. The primary function of intraoperative consultation of uterine mesenchymal lesions in a hysterectomy specimen is to rule out malignancy. Careful gross inspection with attention to tumor border infiltration, color, and texture is crucial for adequate sampling of a uterine mesenchymal neoplasm for frozen section evaluation.
