A heterotopic or ectopic pancreas is defined as the presence of pancreatic tissue that lacks anatomic and vascular continuity with the main body of the pancreas. Pancreatic heterotopia is characterized by the presence of pancreatic acinar, islet, and ductular elements. Most examples are incidentally encountered during surgery, and, on rare occasions, epigastric pain, weight loss, hemorrhage, gastric outlet obstruction, and intussusception have been directly attributable to the presence of the heterotopic pancreas. A malignant transformation in an ectopic pancreas is exceptional and intestinal obstruction of the small bowel by an adenocarcinoma arising in an ectopic pancreas has not been reported yet. We present the case of a ductal adenocarcinoma originating in the heterotopic pancreas in the jejunum of a 73-year-old man. The tumor was found to obstruct the jejunum at a distance of about 25 cm distal to the ligament of Treitz. The resected jejunum histologically showed a ductal adenocarcinoma that originated from the ectopic pancreas. To our knowledge, this would be the first case in Korea, which the patient presented with a small bowel obstruction due to a malignant transformation of an ectopic pancreas.

One hundred and fifty two patients presenting with palpable primary breast cancer were studied to evaluate accuracy of clinical assessment, mammography, and ultrasonography in measuring tumor size. The clinical, mammographic, and ultasonographic diameter of tumor size was compared to histological diameters. The histological diameter of tumors was 27.9+/-12.7mm. The average diameter of tumor on clinical assessment was 33.8+/-13.1mm and its correlation coefficient to the histological size was 0.73. The average size on the mammography was 21.4+/-9.0m and its correlation coefficient to the histological size is 0.71. The tumor size on the ultrasonography in 22 patients was is 22.3+/-10.4mm. The sonographic measurement dimonstrated the highest correlation coefficient (0.83). The clinical assessment overstimated the tumor size, but the mammogaphic and sonographic measurement understimated it compared with histological size. The combined measurement with clinical and ultrasonography could be useful method to estimate tumor size preoperatively. And when it is combined with clinical assessment, it is the most reliable and accurate technique.

Apocrine carcinoma is an uncommon, poorly characterized type of breast tumor. The histologic characteristics of apocrine epithelium in malignant breast lesion were first noted by Krompecher(1916), while the first detailed description of an apocrine carcinoma is credited to Ewing in 1928. The reported incidence of apocrine carcinoma is approximately 0.4% of breast cancers. Apocrine carcinoma has distinct histologic and ultrastructural features that distinguish it as a specialized form of infiltrating ductal carcinoma. The finding of a uniform pattern of apocrine differentiation with dense granularity typifying the majority of cells characterizes this variant. We experienced two cases of invasive apocrine carcinoma of the breast and report with a review of the related literature.
