RESUMEN
Leiomyomas are benign smooth muscle tumors, and retroperitoneal leiomyomas without coexisting uterine leiomyomas are extremely rare. Mitotically active leiomyomas, which are leiomyomas with increased mitotic activity, are rarely observed in postmenopausal women, except under the influence of exogenous hormones. This report presents a rare case of a retroperitoneal mitotically active leiomyoma in a postmenopausal woman. The patient presented with an abdominal mass and underwent surgical resection of the retroperitoneal tumor. Pathological examination revealed a mitotically active retroperitoneal leiomyoma with 31 mitotic figures per 10 high-power fields. The patient did not experience recurrence during the 2-year follow-up period. This case highlights the need to consider retroperitoneal mitotically active leiomyomas in postmenopausal women and suggests that myomectomy can prevent their recurrence.
RESUMEN
In recent years, laparoscopy and endoscopy cooperative surgery(LECS)is reported as the treatment of gastric cancer. We report closed LECS performed for an elderly patient with remnant gastric cancer and gastric cancer in a patient with lung cancer. Case 1 is an 85-year-old male. Early gastric cancer was pointed out in the remnant stomach after distal gastrectomy. ESD was not indicated because of the size of tumor. Because of his age and many comorbidities, closed LECS was performed. Postoperative pathological diagnosis was pT1a(M), pPM0, pDM0, Ly0, v0. Case 2 is a 56-year-old male. He was undergoing chemotherapy for lung cancer with pleural dissemination. Upper gastrointestinal endoscopy revealed early gastric cancer. ESD was not indicated for this lesion because of the depth of tumor. Pleural dissemination of lung cancer is his prognostic factor, and gastrectomy with lymph node dissection was considered excessively invasive. Therefore, closed LECS was performed. Postoperative pathological diagnosis was pT1b2(SM2), pPM0, pDM0, Ly1c, v1a. Closed LECS could be useful therapeutic option for early gastric cancer.
