AIM To demonstrate the role of cytopathology in examining tumours found at post mortem examination. METHODS Tumour deposits were found in 25 hospital necropsies. Cytological diagnosis made at the time of necropsy was compared with subsequent paraffin wax embedded histological sections. RESULTS In 19 out of 20 cases with no previous histological diagnosis, cytology at the time of necropsy pr...

The study was undertaken to answer the question that how many patients with pigmentation of back and arms actually have amyloid deposits in pathology. 44 patients presenting with diffuse pigmentation of back and arms (DPOBA) were selected. Skin biopsies were performed in all cases from the affected sites. On all formalin fixed and paraffin embedded specimens, the following histochemical stains ...

Extensively washed, ethanol fixed and paraffin embedded colonic specimens from 15 patients with ulcerative colitis (UC) and nine patients with Crohn's disease (CD) of the colon, ileal specimens from six patients with CD of the ileum, and histologically normal control specimens obtained from 10 patients operated for colonic carcinoma, were examined by immunohistochemistry with a monoclonal antib...

The needle biopsies from 60 transplanted and native kidneys have been processed and a prospective analysis of pattern, intensity and distribution of immunoglobulin deposits (IgA, IgG and IgM) and complement components (C3c and C1q) identified in these lesions has been carried out by immunohistochemistry with three step immunoperoxidase, in the period from 2000 to 2004. Those deposits were previ...

This report contains the results of attempting to improve on the results of Scott R. Sawyer and Alan M. L’Esperance research paper “Investigation of Paraffin Wax as an Energy Storage Medium Within a Shell-and-Tube Heat Exchanger.” The overall goal of the paper mentioned was to investigate the usefulness of wax as an energy storage medium. Scott R. Sawyer and Alan M. L’Esperance determined that ...

A 57-year old woman with thyroid carcinoma manifesting overt thyrotoxicosis is presented. After the patient had been made euthyroid with propylthiouracil, right lobectomy and lymph node dissection were performed. Permanent paraffin sections revealed follicular adenocarcinoma with capsular and vascular invasion. Metastases to the right humerus, both femurs, the skull and pleural cavity became pr...

The distribution of IgM and IgG in 20 cases of lichen planus and five cases of non-specific inflammation were studied by the unlabelled antibody-enzyme (PAP) technique. Routine paraffin sections were used. In lichen planus deposits of immunoglobulins were seen in and around epithelial cells, in colloid bodies, at epidermo-dermal junctions, and in some inflammatory cells. All cases examined for ...
