Signet-ring histiocytes in typhoid fever

Nonneoplastic endometrial signet-ring cells. Vacuolated decidual cells and stromal histiocytes mimicking adenocarcinoma.

We describe 5 patients (mean age, 50 years; all had uterine bleeding) whose routine endometrial biopsy and curettage specimens contained prominent signet-ring cells. Each specimen contained loose aggregates of signet-ring cells scattered within the endometrial stroma that were characterized by peripherally displaced, small, uniform nuclei with indistinct nucleoli and showed no mitotic activity....

HEMOPHAGOCYTIC SYNDROME IN TYPHOID FEVER AND BRUCELLOSIS

Hemophagocytic syndrome is a non-malignant process that is characterized clinically by fever, hepatomegaly, splenomegaly, pancytopenia in peripheral blood, and reactive histiocytes in the bone marrow. Bacterial infectious diseases like typhoid fever and brucellosis and viral infections including CMV, herpes viruses, and Epstein-Barr virus are diagnosed as the cause of this syndrome. In thi...

A 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 ...
