The Conservative Treatment of Rectal Perforation after Insertion of A Stent and Chemo-Radiotherephy in the Patient with Obstructive Rectal Cancer

The use of self-expanding metal stent has been widely reported that its utility can make a palliative decompression treatment and one stage operation without doing colostomy in the patient with unresectable and resectable obstructive colorectal cancer, respectively. It, however, can sometimes cause complications such as intestinal perforation. We report that the conservative treantment could be possible without removing stent or performing laparotomy in case of intestinal perforation during chemoradiotheraphy after insert of stent for relieving colonic obstruction in the 53 years old female patient with stage IV rectal cancer.

Primary Osteosarcoma of the Breast: A case report

Primary osteosarcoma of the breast is very rare. There have been no previously reported cases in Korea. In this paper, a case of primary osteosarcoma of the breast is reported. It should be distinguished from a carcinoma with extensive osseous metaplasia. Immunohistochemical and ultrastructural studies proved that the lesion, in the absence of epithelial differentiation, was a primary osteosarcoma of the breast rather than a carcinoma with extensive osseous metaplasia. Diagnostic aspects and treatment are discussed and a literature review is given.

Breast Cancer and Additional Primary Cancer : Two case reports

The pathologic standards of multiple primary malignant neoplasms are : 1) Each tumor should be pathologically malignant. 2) Each tumor should be an independent malignancy, and not the result of submucosal or intraepidermal malignant changes. 3) Additional malignancies should not be metastatic. Multiple primary malignant neoplasms which have these standards have been studied continuously, no conclusive evidence for causal relationship has been established. Especially, many reports on the association of breast cancer with thyroid disease or salivary gland tumors have been published, but without any definite evidence. In 1984, Dr. Schenker, however, declared that during an 18-year study, 10,302 cases of breast carcinomas were diagnosed, and, of these, 984 patients(8%) had multiple primary malignant tumors. A significantly higher than expected incidence of second primary cancers occurred at the following five sites : the opposite breast, the salivary glands, the uterine corpus, the ovaries, and the thyroid. The authors report one example of Grave's disease and an other example of pleomorphic adenoma in breast cancer patients.
