A Case of Metachronous Metastasis to the Breast from Non-Small Cell Lung Carcinoma / Journal of the Korean Cancer Association, 대한암학회지

Breast metastases from an extramammary primary tumor are very rare and the prognosis for such patients is generally poor. We report here on a case of a 42-year-old female with metastasis of non-small cell lung cancer to the breast, and she is now being followed up on an outpatient basis. In 2004, she presented with a solitary pulmonary nodule in the left lung, and this lesion had been noted to have gradually increased in size over time. The final pathological diagnosis was adenocarcinoma, and the diagnosis was made by performing percutaneous needle aspiration and lobectomy of the left upper lobe. Adjuvant chemotherapy and radiotherapy were given. Unfortunately, a nodule in the left breast was noted three years later, and metastatic non-small-cell lung cancer to the breast was diagnosed by excisional biopsy. Making the correct diagnosis to distinguish a primary breast carcinoma from a metastatic one is important, because the therapeutic plan and outcome for these two types of cancer are quite different.

A case of colonic adhesion caused by appendiceal origin pseudomyxoma peritonei / 대한내과학회지

Mucocele of the appendix is an uncommon disorder, usually found incidentally during ultrasonography or radiographic studies. It occurs predominantly in the sixth or seventh decades,and has a distinct female predominance. Pseudomyxoma peritonei is a rare condition resulting from a ruptured mucin-producing lesion of the appendix or ovary. It is not easily diagnosed clinically before operation and only histopathologic finding provides the correct final diagnosis. Treatment should consist of evacuation of the mucinous ascites and removal of the mucocele. Reoperations for correction of intestinal obstruction may be needed. The role of chemotherapy is uncertain, and external radiation is probably of no value. We experienced a case of colonic adhesion caused by pseudomyxoma peritonei that originated from the vermiform appendix. This patient was 75 year old female who had suffered from lower abdominal pain associated with constipation and tenesmus for 5 days. We performed ileocecal resection and ileocecal anastomosis. We report this case with brief review of the literature.
