Changes in the humoral, cellular and phagocytic components of the immune system were investigated in 44 biopsy proven, untreated patients of non-Hodgkin's lymphoma (NHL). There was significant decrease in the total lymphocyte number, their subsets (T and B) and the T helper (T mu) population. Impaired leukocyte migration inhibition response and DNA synthesis following stimulation by phytohaemagglutinin were noted. Significant reduction of serum IgA was found in patients of both diffuse and nodular NHL. Phagocytic activity and nitroblue tetrazolium (NBT) reduction were unaltered, but chemotaxis was significantly reduced and bactericidal activity showed variable results.

Histological features and mucin characteristics of 53 cases of periampullary carcinoma, a rare group of epithelial tumors is presented. The cases comprised of 17 resected specimens and 36 endoscopic biopsies. Jaundice was the commonest symptom. The mean tumor size was 2 cms diameter (1-6 cms). Forty cases were characterised as well differentiated adenocarcinoma, 5 as moderately differentiated adenocarcinoma, 5 as mucin secreting adenocarcinoma, 3 as papillary adenocarcinoma and 1 as undifferentiated carcinoma. Desmoplasia and insignificant mitosis were amongst the commonly encountered histological features. Forty four cases (83%) stained positive for mucin (PAS-AB) with a majority of them (66%) predominantly showing acidic mucin. The likely prognostic implication of this feature is discussed.

Histological analysis of 33 rectal biopsies from 26 patients of solitary ulcer syndrome (SUS) of rectum was undertaken. Fibrous obliteration and smooth muscle extension into the lamina propria were the characteristic and most constant findings. The limitation of the biopsy procedure in procuring deeper tissue made the detection of colitis cystica profunda rare in our study. A combination of fibrosis of the lamina propria, superficial mucosal ulceration, muscularis mucosae hypertrophy and submucosal fibrosis, along with the clinical suspicion should clinch the diagnosis of SUS.
