A 52-year-old woman underwent a hysterectomy for a large tumor of the uterine cervix that was shown to be a xanthomatous leiomyosarcoma (LMS) by histologic examination, the first example of this tumor in this site. Two previous similar tumors have been reported in the uterine corpus.

Xanthogranulomatous pyelonephritis is an uncommon chronic destructive granulomatous process of renal parenchyma in association with long-term urinary tract obstruction and infection. It affects females more often than males, with a wide range of age, from newborn to elderly. Almost all patients are symptomatic and the most common symptoms are flank or abdominal pain, lower urinary tract symptoms, fever, palpable mass, gross hematuria, and weight loss.

Pleomorphic leiomyosarcoma (PLMS) was recently described as a morphologic variant of leiomyosarcoma; however, its diagnostic criteria, as shown by morphologic features and biologic behavior, remain controversial. We describe 28 cases of pleomorphic sarcoma with pleomorphic areas in more than two thirds of the tumor and an ordinary leiomyosarcomatous fascicular area covering less than one third as PLMS. PLMS comprised 8.

Sixty-three pure mesenchymal tumors of the uterus were studied to explore the value of immunostaining in the diagnosis of unusual mesenchymal tumors encountered in the uterus, some not reported previously. Each tumor was evaluated using a panel of immunostains including actin, desmin, vimentin, S-100 protein, and cytokeratin. The final classification, which incorporated the immunohistochemical findings, resulted in the identification of 33 relatively common pure mesenchymal tumors (13 benign and malignant endometrial stromal tumors and 20 benign and malignant smooth muscle tumors) and 30 uncommon tumors (five leiomyosarcomas with osteoclastic giant cells, two xanthomatous leiomyosarcomas, one melanotic schwannoma, one pure rhabdomyosarcoma, one neurofibroma, five plexiform tumorlets, and 15 combined smooth muscle-stromal tumors).
