Morphologic Features Suggestive of Gluten Sensitivity in Architecturally Normal Duodenal Biopsy Specimens

Morphologic features suggestive of gluten sensitivity in architecturally normal duodenal biopsy specimens.

We studied small bowel biopsy specimens with architecturally normal villi from 78 adult patients with potential gluten sensitivity (GS) and correlated them with outcome to characterize morphologic features that would allow a pathologist to suggest GS. No patient had a previous GS diagnosis. Twelve study patients had GS. The mean number of intraepithelial lymphocytes (IELs) per 20 enterocytes fr...

Morphologic features of endometriosis in various types of cytologic specimens.

Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. This study evaluates the cytomorphologic features of endometriosis in various cytologic specimen types [fine-needle aspiration (FNA), effusion cytology (EF), touch imprint (ToP), and cervical smear (PAP)], and assesses the key elements helpful in recognizing this lesion. A total of 18 cases (8 FNA, 4 EF, ...

Diagnostic value of direct immunofluorescence of mucosal and skin biopsy specimens on formalin-fixed paraffin-embedded biopsy specimens compared to specimens placed in normal saline as the gold standard method in the diagnosis of a group of autoimmun

Background and Aim: Direct immunofluorescence (DIF) is represented as a gold standard method in diagnosis of autoimmune blistering dermatoses. Normal saline, liquid nitrogen and michel’ solution are a widely accepted media for preserving biopsy samples of skin or mucosa before DIF examination. Occasionally clinicians put the biopsy specimen taken for DIF in formalin 10%, occasionally clinicians...

Intraepithelial lymphocytes in the villous tip: do they indicate potential coeliac disease?

BACKGROUND The counting of intraepithelial lymphocytes (IELs) in the villous tips of architecturally normal small bowel biopsy specimens was proposed as a method to measure mucosal infiltration in gluten sensitive patients. AIMS To apply this straightforward method in duodenal biopsy specimens from patients affected by potential coeliac disease (PCD) to verify whether it can discriminate thes...
