Article Abstract
Primary mucinous cystadenocarcinoma (MCA) is a rare breast carcinoma subtype showing overlapping histopathological features with mucinous cystadenocarcinoma of the ovary and pancreas. Current literature data suggest a favorable prognosis of breast MCAs despite its immunoprofile usually revealing lack of expression of estrogen receptor, progesterone receptor and HER-2 and high Ki67. As far as we know, only 36 cases have been reported in the literature to date. Its ambiguous morpho-phenotypic profile makes histological diagnosis very challenging. It must be distinguished from typical mucin-producing breast carcinomas and, above all, metastases from the same histotype in other sites (ovary, pancreas, appendix). Herein, we report the case of a primary breast MCA occurring in a 41-year-old female with peculiar histological features.

Background: Ovarian cancer remains a major clinical challenge with more than 40.000 annual deaths in Europe and in the United States, highlighting the need for better diagnostic and therapeutic strategies. This study first presents an immunohistochemical evaluation of the extra-domains A and B containing fibronectin (EDA-FN, EDB-FN), fibroblast activation protein (FAP), and carcinoembryonic antigen (CEA) in ovarian cancer specimens.

Introduction And Importance: Mucinous cystic pancreatic neoplasms (MCPNs) are cystic lesions often seen in the body and tail of the pancreas.
Case Presentation: In the case reported here, we presented a 39-year-old woman with complaints of upper abdominal pain. It presents with a variety of signs and symptoms, the most common being upper abdominal pain, early satiety, and dyspnea.
Tumors of the right uterine appendages cannot always be distinguished from mucous neoplasms of the appendix (MA) at the preoperative stage. According to the literature, MA is traditionally considered more common in women than in men at the age of 50 years, with a ratio of 4:1. We have identified 2 cases of surgical treatment of MA in gynecological practice, one of mucinous cystadenoma and the other of mucinous cystadenocarcinoma.

Mucinous cystadenocarcinoma arising from mature cystic teratoma is an uncommon entity. The possibilities are either due to malignant transformation of benign teratoma into adenocarcinoma or a collision tumor between a mature cystic teratoma and a mucinous tumor. Here we present a case of a woman with abdominal distension and vague abdominal pain.
