A case of mucinous carcinoma of the breast with neuroendocrine differentiation in an 89-year-old woman is presented. The patient presented with a rapidly growing right breast mass, which she had had for 2-3 years. The tumor, 15 x 8 x 5 cm, was located mainly in the upper outer quadrant. Light microscopy revealed a pure mucinous carcinoma of type B. Neuroendocrine differentiation was demonstrate...

A 79-year-old Indian male was admitted with upper abdominal discomfort of 1-year duration which was associated with loss of weight and appetite. Serum tumor markers, including carcinoembryonic antigen and carbohydrate antigen 19-9, were within normal limits. A computed tomographic scan demonstrated a cystically dilated and tortuous pancreatic duct measuring 1.9 cm, suggestive of an intraductal ...

in females, the most common cancer is breast carcinoma in which squamous cell carcinoma (scc) is a rare type of malignancy. histologically, infiltrating ductal carcinoma is the most common type and lobular, mucinous, and medullary types have lower incidence. pure scc of the breast can originate from the skin, nipple, or epithelium of a deep‑seated dermoid cyst or squamous metaplasia on chronic ...

A 48 years old man presented with subacute intestinal obstruction resulting from an intraluminal colorectal mass. He underwent partial colectomy. Histological diagnosis of mucinous adenocarcinoma with focal areas of heterotopic ossification was made. Although the presence of heterotopic ossification has no known prognostic implication in colorectal carcinoma, however, it is important that both ...

Mucinous carcinoma is a rarely occurring form of breast cancer that exists in two forms, pure and mixed. Differentiation between these is based on the amount of extracellular mucin in the tumor. This malignancy has a more favorable prognosis when compared to other forms of breast cancer, however diagnosis can be challenging as the imaging findings may not be suggestive of breast cancer. Because...

Solid mural nodule within a mucinous cystic ovarian tumor occurs more often than generally presumed. One especially interesting case involving coincidental cervical carcinoma is presented. A 38-year-old woman underwent exploratory laparotomy for a right ovarian tumor. After ovarian malignancy had been diagnosed from frozen section, the bilateral salpingo-oophorectomy and hysterectomy was perfor...

1.3.1. Histopathologic types (according to World Health Organization/ International Society of Gynecological Pathology classification) All tumors are to be microscopically verified. The histopathologic types are: • Endometrioid carcinoma: adenocarcinoma; adenoacanthoma (adenocarcinoma with squamous metaplasia); and adenosquamous carcinoma (mixed adenocarcinoma and squamous cell carcinoma). • Mu...

Background: Mucinous ovarian tumors differ from other types of epithelial cancers in their clinical behaviour and the need for innovative treatment approaches to achieve improved patient outcomes. Immunohistochemistry plays an important role diagnosis differentiates primary secondary mucinous tumors. To know distribution expression CK7 CK20 ovary gastrointestinal tract.Methods: Ninety eight cas...

The goals of the study were to determine what percentage of neoplasms with a bronchioloalveolar (BAC) component were considered pure BAC by current World Health Organization (WHO) criteria. Next, we wanted to determine the number of mucinous BACs using histochemical staining with Alcian Blue PAS. Finally, we aimed to elucidate by immunohistochemistry the thyroid transcription factor-1 (TTF-1) f...

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...
