Primary retroperitoneal mucinous cystadenocarcinoma is an extremely rare tumor. Preoperative diagnosis is very diffi cult and the treatment remains controversial. A 37-year-old Korean woman (gravida 0) presented with a huge abdominal mass. Computed tomography scan revealed an 18 × 11 cm sized unilocular cyst with irregular wall thickening and solid component at right adnexa. Serum CA 19-9 was s...

INTRODUCTION Mucinous cystadenoma is the most common of benign neoplasms of the appendix and carcinoid is the most common type of primary malignant lesions of the appendix.We report a rare case of a 57-year-old female with combined mucinous cystadenoma and carcinoid tumor of the appendix.Dual carcinoid and epithelial neoplasia is a rare occurrence in the appendix. CASE REPORT A 57-year-old Ca...

RATIONALE Sarcomatous or anaplastic carcinoma mural nodules presenting in ovarian mucinous cystic tumors are very rare. Here, we reported the ultrasonic and pathological features of 2 such cases. PATIENT CONCERNS A 60-year-old woman presented with a complaint of lower abdominal pain. Physical examination revealed a hard, palpable mass in her right lower abdomen with mild tenderness. In additi...

UNLABELLED We report a hitherto not documented case of primary mucinous cystadenoma arising in the spermatic cord within the right inguinal canal of a78-year-old man. The tumor was painless, hard and mobile. A computed tomography scan on the pelvis revealed an oval shaped, low attenuation mass, measuring 5.0x2.5x2.1 cm, that was present adjacent to the vas deferens. Grossly, the excised mass wa...

CONTEXT Despite the recent progress of diagnostic and therapeutic modalities, survival rates of pancreatic adenocarcinoma remain poor, mainly due to late diagnosis. CASE REPORT We report the case of a 56-year-old man who was diagnosed with a symptomatic intraductal papillary mucinous tumor of the pancreas located in the uncus. This tumor was associated with a concurrent stenosis of the isthmi...

We report a very rare case of Peutz-Jeghers syndrome (PJS) composed of multiple genital tract tumors and mucinous adenocarcinoma. A 46-year-old woman presented to our hospital with lower abdominal pain resulting from PJS involves sex cord tumor with annular tubules (SCTAT), ovarian mucinous tumor, ovarian serous tumor, mucinous adenocarcinoma of colon. The CEA concentration is high before surge...

Mucinous cystadenocarcinoma is an extremely rare variant of primary breast tumor which is histologically similar to mucinous cystadenocarcinoma of the ovary and pancreas. Herein we report a case of a 63 years old woman diagnosed with diverse histological types of non-synchronous rare primary breast tumors, a medullary carcinoma of the right breast and a mucinous cystadenocarcinoma of the left b...

BACKGROUND Mucinous breast carcinoma (MC) is a special type of breast cancer that presents with a large amount of extracellular mucin. MC comprises approximately 4% of all invasive breast cancers. This type of tumor has a better prognosis and higher incidence in peri- and post-menopausal patients. Pathologically, there are two main subtypes of MC: pure and mixed. In this study, we describe 10 y...

OBJECTIVE The objective of our study was to determine the accuracy of MRI in the preoperative staging and classification of mucinous appendiceal neoplasms and to describe the MRI features that are useful for selecting patients for surgical resection. MATERIALS AND METHODS Twenty-two patients underwent preoperative MRI including T1-weighted, T2-weighted, immediate gadolinium-enhanced, and dela...

background: ovarian cancer comprises a heterogeneous group of neoplasms. the prognosis cannot be predicted by histopathologic examination alone. the aim of this study is to evaluate p53, pten, and β-catenin expressions in primary ovarian carcinomas in an attempt to find a possible relationship with morphologic parameters and clinical findings. methods: the study included 100 epithelial ovarian ...
