Significance of mucin stain in uterine cervical cancers.

Histopathological examination of 140 cases of cervical cancer was supplemented with staining for the presence of mucin. Secretion of mucin was detected in 27 cases. Fourteen cases of large cell non-keratinizing (LCNK) squamous cell carcinoma were reclassified, 12 as squamous cell carcinoma with mucin secretion and two as adeno-squamous carcinoma. One case of undifferentiated carcinoma was labelled as adenocarcinoma on the basis of mucin stain. None of the keratinizing squamous cell carcinomas were positive for mucin. The results indicate that mucin expression should be looked for even in those carcinomas where no obvious gland formation is seen.

Bilateral testicular biopsy--is it necessary?

Bilateral testicular biopsies from 202 infertile males were examined to ascertain the differences in the degree of damage to the germinal epithelium on both sides. Depending on the histologic changes, the biopsies were divided into six groups. A significant difference in the morphology on both sides was seen only in 3% cases. The left and the right testes were equally damaged in cases with similar morphology.

Congenital deficiency of factor VII.

A case of congenital factor VII deficiency in a five-year-old child is reported. The patient, born of a non-consanguineous marriage, presented with repeated bouts of epistaxis since childhood. The prothrombin time (PT) was markedly prolonged with a normal bleeding time (BT), partial thromboplastin time with Kaolin (PTTK) and platelet count. The patient has been on follow up for the last four years and is doing apparently well.

Interobserver agreement of the Nottingham histologic grading scheme for infiltrating duct carcinoma breast.

Interobserver agreement of the histologic grading scheme for infiltrating duct carcinoma (IDC) of breast was assessed. Three pathologists independently evaluated histologic grade using the modified Bloom and Richardson histological grading system on 40 cases of IDC breast. Pairwise K value for agreement ranged from 0.68-0.83 (median 0.68) for histological grade suggesting substantial agreement. Generalized K values were 0.54, 0.34 and 0.36 for tubule formation, nuclear pleomorphism and mitotic count respectively indicating moderate and fair agreement. Similar levels of agreement were obtained specially in the final histologic grade between pathologists routinely reporting histopathology material and one pathologist who was not. This was achieved by use of precise guidelines. The ease with which this grading system could be applied by pathologists on histopathology material will greatly help its acceptability in routine histopathology.
