Secretory Carcinoma of the Breast: A case report.: Kyu Rae Kim, Jung Hyun Yang, Yeon Lim Seo, Howe Jung Ree; Korean J Pathol. 1996;30(4):347-350.

Abstract PDF: We report a case of secretory carcinoma with axillary lymph node metastasis in a 21-year old woman. She was aware of a mass in her breast for 10 years and noticed a rapid growth of the preexisting mass during the last years. Histologically, the tumor was composed of micropapillary and microcystic or cribriform glandular structures which contained eosinophilic, mucinous, intraluminal secretions. The center had a dense hyalinized strama with a solid infiltrative growth of tumor cells with intracytoplasmic secretory vacuoles at the periphery. In addition, marked intraductal papillary epithelial proliferations were present at the superficial portions of the tumor near the nipple. Prognostic factors and their relationship to juvenile papillomatosis are discussed with a review of the literature.

Biliary Papillomatosis: A Report of Two Cases.: Mi Jin Gu, Joon Hyuk Choi; Korean J Pathol. 2003;37(6):446-450.

Abstract PDF: We report two cases of biliary papillomatosis, a rare disease which is characterized by multiple, papillary adenomas of the intrahepatic and/or extrahepatic bile ducts.
Case
s 1 and 2 were a 45-year-old woman and a 61-year-old woman, respectively, with upper abdominal pain. Abdominal computed tomography scan of case 1 revealed a 4-cm sized cystic and solid mass within the dilatated intrahepatic bile duct. Hepatobiliary ultrasonography of case 2 showed dilatation of the main intrahepatic and common bile duct with nonshadowing echogenic material. Soft, friable papillary masses were noted grossly in the dilated intrahepatic bile duct. Microscopically, the tumor was composed of papillary structures, most of which were lined by a layer of tall columnar cells. Complex papillary fronds with pseudostratification, cellular atypia, structural atypia and foci of invasion were noted in case 2. The p53 expression increased in the dysplastic and carcinomatous area and was correlated with the Ki-67 labeling index.
