Childhood lymphoma in southern Iran.

A study of 81 childhood lymphomas diagnosed in the Department of Pathology of Pahlavi University Medical Center, Shiraz, Iran, encompassing all histologically diagnosed childhood lymphomas from the Fars Province, Southern Iran over a 14-year period (1963--1976) revealed a 3:1 male predominance and a 1:4 frequency compared to adult lymphomas. Peripheral lymphadenopathy at the initial physical examination was almost twice as common as deep node involvement. Comparison of cumulative and age-standardized (to world population) incidence rates with those of selected Tumor Registries in various continents revealed a higher rate in our region of both non-Hodgkin's and Hodgkin's lymphoma relative to some of the Western countries. Our incidence rates were in general intermediate between Western populations on one hand and some South America, African and Asian populations on the other. Hodgkin's disease accounted for 64% (males) and 88% (females) of lymphomas and mixed cellularity was the commonest histologic subtype. Histologically almost all non-Hodgkin's lymphomas were diffuse at the time of diagnosis.

Colorectal polyps and carcinoma in Southern Iran.

A study was made of the prevalence of colorectal polyps (excluding juvenile polyps, familial polyposis coli and villous adenomas) and the minimum frequency of colorectal carcinoma in Southern Iran. A total of 801 large intestines from necropsies performed on individuals 20 years or older was examined with or without magnifying lens for presence of polyps. Our prevalence rate was then compared with those reported on postmortem material from the USA, Australia, South Africa (Bantus), Colombia, and Hawaii (Japanese immigrants). Our surgical pathology files were reviewed for colorectal polyps over a 22-year period (1952-1973). Colorectal carcinomas diagnosed in the Department of Pathology were reviewed over 11 years (1963-1973) and the minimum frequency rates compared with corresponding age- and sex-specific incidence rates from Connecticut, USA. The data indicate 1) a very low prevalence rate for colorectal polyps as well as carcinoma in our region and 2) a rather striking predominance of right-sided colonic carcinoma.
