A characteristic type of reticular cell, the dense reticular cell is described and illustrated by electron microscopy in the thy mus and lymph nodes of mice. This cell is identified by its high nuclear and cytoplasmic density and by the presence of many ribosomes in its long, slender processes extending between lym phocytes (or thymocytes). The preservation of these processes requires special f...

Background: Cervical Lymphadenopathy is a relatively common finding in pediatric age group and is caused by a wide spectrum of diseases from transient infections to malignancies especially lymphomas. Objectives: Evaluation of the reliability of gray scale and Doppler Sonography in differentiation of reactive from malignant enlarged cervical lymph nodes. Materials and Methods: Thirty untreated p...

Little is known about tick-borne diseases in Saudi Arabia, particularly regarding the prevalence of theileriosis in small ruminants. This survey studied the potential vectors of malignant theileriosis in Saudi Arabian sheep. Blood, lymph node and tick samples were collected from animals being treated or necropsied at the Veterinary Diagnostic Laboratory in Jeddah, Makkah (western region), and B...

UNLABELLED PURPSOE: To investigate the diagnostic value of quantitative analysis of a tissue diffusion and virtual touch tissue imaging quantification (VTIQ) technique with acoustic radiation force impulse (ARFI) elastography for assessing enlarged cervical lymph nodes. MATERIALS AND METHODS Fifty-six enlarged cervical lymph nodes confirmed by pathologic diagnoses were covered in the study. A...

BACKGROUND CT plays a valuable role in assessment of patients with a wide variety of diseases of the pleura, and pulmonologists should be aware of the significance of different CT findings for the differential diagnosis of benign and malignant pleural diseases. METHODS 155 patients with pleural disease who had undergone CT scans of the lungs and thorax before treatment were enrolled. We retro...

Atypical cells have been consistently found in the palatine tonsil (PT) in patients with breast, stomach, and rectal cancer, and less often with gastric polyposis, mastopathy, and soft tissue papilloma. The vast majority of the atypical cells is represented by reticular cells, which are found in smears irrespective of the tumor stage. The number and size of PT atypical reticular cells in patien...

I HE STRUCTURE and cellular composition of lymph nodes in various species have been thoroughly studied with both the light15 and the electron micrOscope.6’8 These studies have adequately served to describe and classify the cells in the lymph node and have led to general agreement on the appearance and location of the various cell lines. From these studies have also come descriptions of structur...

Naive T cells encounter antigen-presenting cells within the cortex of lymph nodes to initiate primary immune responses. Within this T cell cortex is the reticular network (RN)--a system of collagen fibers and extracellular matrix (ECM) wrapped by fibroblastic reticular cells (FRC). We have investigated the distribution of various molecules, including ECM proteins and proteoglycans, in the T cel...

Oral lichen planus (OLP) is an immunologically T cell-mediated disease caused by an unknown stimulus. Despite intensive investigation its pathogenesis still remains unknown. A few possible associations between OLP and certain diseases such as thyroid and malignant diseases as well as specific medication intake have been proposed in the literature with inconsistent findings. We aimed to investig...
