Computed tomography showed right lung nodule and abdominal mass attached to the gastric wall, measuring approximately 30 mm and 70 mm in diameter. Since biopsy samples from the lung and abdomen revealed poorly differentiated adenocarcinoma and malignant tumor, clinicians first interpreted the abdominal mass as metastatic carcinoma, and a right lower lobectomy with following resection of the mass was performed. Gross examination of both lesions displayed gray-whitish to yellow-whitish cut surfaces with hemorrhagic and necrotic foci, and the mass attached to the serosa of the lesser curvature on the gastric body. On microscopic examination, the lung tumor was composed of a proliferation of highly atypical epithelial cells having abundant eosinophilic cytoplasm, predominantly arranged in an acinar or solid growth pattern with vessel permeation, while the abdominal tumor consisted of sheets or nests with markedly atypical epithelioid cells having pleomorphic nuclei and abundant eosinophilic to clear cytoplasm focally in a radial perivascular or infiltrative growth pattern. Immunohistochemically, the latter cells were positive for HMB45 or α-smooth muscle actin, but the former ones not. Therefore, we finally made a diagnosis of malignant perivascular epithelioid cell tumor(PEComa) arising in the gastric serosa, combined with primary lung adenocarcinoma. Furthermore, small papillary car-cinoma of the thyroid gland was identified. The current case describes the coincidence of malignant PEComa with other carcinomas, posing a challenge in distinction from metastatic tumor disease.展开更多

Methods: 18 patients with gast ropa resis afte r gast ric cance r sur gery were divided into two gr oups, including 10 pa ti ents in the obse rva tion group and 8 pati ents in the cont rol group. The observation group was treated with traditional Chinese medicine combined with warm acupuncture and moxibustion, and the control group was treated with western medicine. Results: After 7 days tr eatment, the re was significant diffe rence in cure r ate and total effective rate between the two groups (P < 0.01), and the treatment group was obviously superior to the control group. Conclusion: Traditional Chinese medicine combined with warm acupuncture is effective in the treatment of postoperative gastroparesis of gastric cancer.展开更多
