Background: Hirschsprung disease is a complex genetic disorder of the enteric nervous system (ENS), often called congenital aganglionic megacolon and characterized by the absence of enteric neurons along a variable length of the intestine. The definitive diagnosis of Hirschsprung disease relies on histologic and/or histochemical staining of sections fr...
introduction constipation is one of the most common causes of referral to pediatric gastroenterology clinics. the histopathology and immunohistochemistry (ihc) studies indicated that several neurons are currently detectable in motility of the gut. we aimed to evaluate calretinin in the children with chronic constipation. materials and methods in this cohort study, 40 children with chronic const...
BACKGROUND Hirschsprung disease is a complex genetic disorder of the enteric nervous system (ENS), often called congenital aganglionic megacolon and characterized by the absence of enteric neurons along a variable length of the intestine. The definitive diagnosis of Hirschsprung disease relies on histologic and/or histochemical staining of sections from suction rectal biopsies. Calretinin immun...
Background Rectal biopsy and its histopathological study with hematoxylin and eosin (HE) is the gold standard for Hirschsprung's disease (HD) diagnosis. However, there are some limitations in the diagnosis of ganglion cells in HE approach. Recently, it was reported that the utility of Calretinin is a reliable ancillary immunohistochemistry (IHC) test for HD diagn...

BACKGROUND Hirschsprung's disease (HD) is a congenital intestinal motility disorder with absence of ganglion cells in the colonic wall. Diagnosis of the disease is mainly based on the identification of the lack of ganglion cells in the pathology sections of the colon which is very difficult and time consuming and also needs several serial cut sections. There are many proposed markers in this fi...
BACKGROUND The use of calretinin immunostain (IHC) in the evaluation of rectal suction biopsies for Hirschsprung disease (HD) has been reported by Kapur et al. and others. The first goal of this article is to report our institutional experience with the use of calretinin in specimens for evaluation of HD. The second goal is to describe the pattern of expression of calretinin in the junction of ...
Background and Objective: Histopathological evaluation of granulosa cell tumors (GCT) of the ovary may be confused morphologically with a wide variety of the tumors. Immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. Although it has been suggested that inhibin can be a sensitive marker for GCT, it maybe had negative results in some cases. In addition, cal...

Objective(s) Definite diagnosis of Hirschsprung’s disease (HD) is based on histopathological study, but there are limitations associated with standard histology and histochemistry in this regard. The aim of this study was to investigate calretinin immunostaining patterns in both ganglionic and aganglionic HD intestinal specimens and to compare them with control specimens. Materials and Method...
