Mucus-secreting 'signet-ring' cells in CSF revealing the site of primary cancer.
نویسندگان
چکیده
A case is reported of leptomeningeal carcinomatosis in which identification of mucus-secreting 'signet-ring' carcinoma cells in the CSF allowed diagnosis of an otherwise asymptomatic gastric cancer. When lumbar puncture is performed, careful cytological examination of the CSF should be carried out in any undiagnosed patient with neurological symptoms and signs.

PURPOSE Gastric cancer has the highest incidence rate among cancers in Asia. The advanced type of signet ring cell carcinoma has poor prognosis compared to other types of gastric cancer. The immuno-gene therapy with cytokine-based tumor vaccines has not yet been investigated for gastric cancer. The granulocyte macrophage colony-stimulating factor (GM-CSF)-based tumor vaccine has been demonstrat...
متن کاملA Review of Signet Ring cells in Salivary Gland Tumors
Objectives: Signet Ring Cells (SRCs) are often seen in gastrointestinal, breast, bile duct and lung invasive carcinomas. Observing these cells in benign and malignant lesions of the salivary glands is not common. Signet-ring cell adenocarcinoma is rare and is commonly seen in the secondary salivary glands. Although, the presence of SRCs in other neoplasms of the body is usually associated with ...
متن کاملKrukenberg tumour of the ovary: a case report with light microscopy, immunohistochemistry and electron microscopy study.
A rare case of a 46-year-old woman with bilateral Krukenberg tumours is reported. Histologically, oedematous ovarian stroma was infiltrated by signet-ring cells arranged singly, in cords or in nests. Immunoreactivity for cytokeratin-7, carcinoembryonic antigen as well as histochemical positivity for mucins demonstrated the epithelial nature of the tumour. The gastric primary site was suggested ...
متن کاملTesticular Signet-Ring Cell Metastasis from a Carcinoma of Unknown Primary Site: A Case Report and Literature Review
Signet-ring cell carcinoma is a highly malignant adenocarcinoma consisting of cells characterized as cytoplasmic vacuoles filled with mucin. The most common primary location of this type of cancer is the stomach, but it may also be found in other organs such as prostate, testis, bladder, ovaries, or colon. To date, metastatic signet-ring cell carcinoma of unknown primary (CUP) site to the testi...
