Primary hepatic leiomyosarcoma is very rare and no primary myxoid leiomyosarcoma in the liver has been reported yet. Most cystic space-occupying lesions in the liver are benign in nature. But, rarely, malignancy could appear as a cystic lesion by ultrasonographic examination. A 64-year-old woman with a huge cystic mass detected by hepatic ultrasonography was diagnosed as primary hepatic myxoid leiomyosarcoma by immunohistochemical and ultrastructural studies after various image studies and fine needle aspiration biopsy of the liver mass.

Primary hepatic leiomyosarcoma is a very rare malignant tumor of the liver and rather slowly progressing disease. When the tumor is solitary or even multiple but located in one lobe, the treatment of choice is an operation. We report a case of huge leiomyosarcoma in a 58-year old female patient treated by surgical resection.

Leiomyosarcoma is an uncommon tumor which arises from various sites including uterus, stomach, retroperitoneum, superficial soft tissues, bladder, kidney, and lung. Primary hepatic leiomyosarcoma is a very rare tumor and fewer than 70 cases of primary hepatic leiomyosarcoma have been reported since the first publication in Japan. And there was only one case report of cutaneous metastasis from hepatic leiomyosarcoma. We recently experienced a case of primary hepatic leiomyosarcoma presenting as subcutaneous palpable mass. Herein we report this case with a review of literatures.

Primary leiomyosarcoma of the nipple-areola complex is extremely rare. Less than ten such cases have been reported in English literature so far. Herein we describe a 52-year-old female presenting with a 1.5 cmx1.1 cmx0.7 cm nodular lesion over her left nipple, and leiomyosarcoma was proved by pathological examination of the excised specimen. Positron emitted tomogram (PET) revealed no abnormal signal other than the primary site. Microscopically, this poorly circumscribed tumor was composed of interlacing bundles of smooth muscle cells with bizarre and pleomorphic nuclei, as well as prominent nucleoli. Its mitotic count was up to 7 mitoses per 10 high power fields (HPF). Immunohistochemical study of tumor cells revealed positive stain for alpha-smooth muscle actin and vimentin; and negative for cytokeratin, CD34 and S-100. Left simple mastectomy was undertaken and no residual mass lesion was noted on the resected specimen. Related literatures about the diagnosis and treatment for breast leiomyosarcoma will be presented here.
