Primary Omental Myxoid Leiomyosarcoma: Report of a Case and a Review of the Literature

A 41-year-old Japanese woman who presented with right lower abdominal pain underwent partial omental resection with tumor excision, leaving no residual tumor. The tumor was diagnosed as a myxoid leiomyosarcoma that apparently originated in the greater omentum. A recurrent omental tumor was excised at 4.5 months after the first operation, and then at 5.5 months after this, CT revealed metastatic sarcoma at the surface of the liver (S7) and the left upper abdomen. She died 20 months after the last operation despite treatment of the metastases with MAID therapy (mesna, adriamycin, ifosfamide, dacarbazine). A literature review revealed that this tumor mainly occurs in the uterus, soft tissue, and cardiovascular system, with a preponderance among middle-aged to elderly women. The present report is the first description of primary omental myxoid leiomyosarcoma

Atypical Carcinoid Tumor of the Lung: Report of a Case with Intrapulmonary Metastasis

A 71-year-old man was noted to have a nodular opacity in S8 of the right lung. Thirteen months later, the chest CT showed a lesion "gloved finger shape " with focal calcification, and a small nodular opacity appeared in right S7. A right lower lobectomy was performed under video-assisted thoracic surgery. The tumor filled the S8 bronchus, with invasion into the pulmonary parenchyma and S7 metastasis. Mitotic figures were seen in 5 of 10 high power fields. Positive staining for chromogranin A and synaptophysin led to the diagnosis of atypical carcinoid. The patient has been disease-free without treatment for 9 months
