Many studies have focused on cyclooxygenase-2 (COX-2) alterations as a critical step in the onset and progression of cancer. Moreover, a strong correlation between COX-2 and chemoresistance has been demonstrated in several carcinomas. Recently, COX-2 expression has been observed in uterine carcinosarcoma, osteosarcoma, and rhabdomyosarcoma. We investigated COX-2 expression in chemoresistant uterine leiomyosarcoma in 30 patients who had undergone surgical treatment. COX-2 expression was observed in 13 cases (43.3%). Of the 13 patients with distinct COX-2 positive immunoreactivity uterine leiomyosarcomas, 7 had stage I or II disease and 6 had stage III or IV disease. The expression of COX-2 in uterine stromal malignancies may reveal a therapeutic hypothesis in the context of uterine leiomyosarcoma molecular chemotherapeutic approach.

Primary cardiac rhabdomyosarcoma is rare. A dismal prognosis is usually given due to its high propensity for distant metastases, with survival rarely exceeding 2 years. We report a case that was initially considered to be a cardiac metastatic tumor from a primary uterine leiomyosarcoma, but after morphological and immunohistochemical examinations was shown to be a primary cardiac rhabdomyosarcoma. The right atrium was filled with a mass that oscillated between the right atrium and ventricle through the tricuspid valve. To reduce the risk of sudden death from tumor embolism into the pulmonary arteries, the tumor was resected. Even though the surgery was not curative, it eliminated the risk of sudden death due to tumor embolism into the pulmonary arteries and improved short-term survival.
