A novel case of left atrial and right lung mass turned out to be unconventional metastasis of uterine leiomyosarcoma with a review of literature

Uterine leiomyosarcoma (ULMS) is a rare malignancy arising from the myometrial smooth muscle wall, and cardiac metastases are extremely rare. Metastasis to the heart is a very unusual finding, and atrial metastasis is even rarer. Here, we report a case of a 45 year old woman who presented with dyspnea and pleural effusion and had a significant history of hysterectomy done for ULMS. Magnetic resonance imaging revealed a left atrial mass, which was resected and revealed to be a metastasis of leiomyosarcoma on histopathology and immunohistochemistry. Metastatic ULMS may rarely present as a left atrial mass with acute clinical presentation. Detailed clinical history and accurate diagnosis are vital for further management.

Leiomiosarcoma cutáneo ulcerado: Reporte de un caso clínico y revisión de la literatura / Ulcerated cutaneous leiomyosarcoma: A case report and literature review

Los leiomiosarcomas cutáneos son neoplasias malignas, originadas en el músculo liso, infrecuentes, tanto en las formas primarias como en el caso de las secundarias o metastásicas. Existen pocos casos publicados en la literatura. Presentamos el caso de un leiomiosarcoma cutáneo primario, en un hombre de 76 años de edad y realizamos una revisión de sus características clínicas y diagnóstico, así como, de las diferencias pronóstico-evolutivas según las distintas localizaciones de esta afección. Por último, debe señalarse que el tratamiento es fundamentalmente quirúrgico, con escisión y márgenes de seguridad, ya que, no existe una respuesta satisfactoria o significativa al tratamiento radiante y/o quimioterápico, siendo imprescindible efectuar un control evolutivo periódico de los pacientes, debido a la tasa de recurrencia local y la posibilidad de ocasionar metástasis, según la localización histológica del tumor.

Leiomyosarcomas located in superficial soft tissue are very rare or uncommon malignant neoplasms, both as primary tumors and as secondary or metastatic lesions. We present the case of a primary cutaneous leiomyosarcoma in a 76-year-old man, reviewing the clinical and diagnostic features, as well as the different prognoses depending on the site at this level. Treatment is basically surgical, involving excision with wide margins since the response to radiotherapy and/or chemotherapy is not satisfactory or significant. Given the high rate of local recurrence and the possibility of metastasis, depending on the histological location of the tumor, periodic follow-up of the patients is essential and indispensable.
