Myxoid leiomyosarcoma of the uterus in a patient receiving tamoxifen therapy: a case report.

In this paper, we present a case of myxoid leiomyosarcoma development in a patient receiving tamoxifen for 3 years because of breast cancer. The myxoid leiomyosarcoma should be included in the differential diagnosis of any uterine tumor with a predominantly myxomatous composition. A review of the literature indicates that tamoxifen may increase not only the risk for endometrial cancer but also for uterine sarcoma, suggesting vigilance for uterine cancer in women who are being treated with this drug.

Frequency, histological, and immunohistochemical properties of massive inflammatory lymphocytic infiltration of leiomyomas of the uterus: an entity causing diagnostic difficulties.

Massive lymphocytic infiltration of the leiomyomas of the uterus is rare and causes diagnostic difficulties. The objective of this study is to estimate the frequency, to analyze the clinicopathologic features, to explore the possible pathogenetic factors, and to discuss the differential diagnosis of this entity. We reviewed the pathology reports of 379 patients who underwent surgery for leiomyomas at our institution, from 1999 until 2003, and we identified five cases of leiomyomas with massive lymphocytic infiltration.
