Signet Ring Cell Carcinoma Pathology Outlines

Tumor budding is an important additional prognostic factor for patients with colorectal cancer (CRC). Defined as the presence of single tumor cells or small clusters of up to 5 cells in the tumor stroma, tumor budding has been likened to an epithelial-mesenchymal transition.

Metastatic gland forming and especially signet ring carcinoma in the abdomen and pelvis should always raise the possibility of gastric adenocarcinoma. Tall columnar cells with prominent dirty necrosis should suggest colorectal primary instead. Immunohistochemistry is usually not definitive.

Signet-ring cell carcinoma (SRCC) of the ampulla of Vater is an uncommon histologic type at this site. It was first described by Sekoguchi et al in 1979. Nine more cases have been reported [4–10,26,28]. We report a woman with signet-ring cell carcinoma in the ampulla of Vater.

This article deals with prostate cancer. The vast majority of prostate cancers are carcinomas and could be labelled prostatic carcinoma.Most prostatic carcinomas are gland forming; thus, they can be labelled prostatic adenocarcinoma or adenocarcinoma of the prostate. Benign pathology of the prostate gland, and prostate histology and anatomy are dealt with in the prostate gland article.

contrast to the goblet cell–type MCC, signet ring–type tu-mors are associated with a poorer prognosis. In addition, one needs to distinguish mucinous cystadenomas and mu-cinous bronchioloalveolar cell carcinoma (BAC) from MCC. Mucinous cystadenoma is a benign neoplasm that is gen-erally much smaller, has a fibrous capsule, and lacks the

INTRODUCTION — Colorectal cancer (CRC) is a common and lethal disease. The risk of developing CRC is influenced by both environmental and genetic factors. The epidemiology of CRC and risk factors for its development will be discussed here.

It is difficult to distinguish primary SRC adenocarcinoma of the bladder from bladder metastasis of SRC carcinoma of the stomach only based on histological findings.

SRCC were in general poorly differentiated tumors (57%), small proportion of patients included were well-differentiated tumors with focal signet ring cell pathology (10%) and in 33% grade was unknown. Among stage 3 patients, 34% patients received only surgery while 64% received surgery with adjuvant chemotherapy and 2% received chemotherapy alone.
