Two hundred and ninety cases of non-Hodgkin's lymphoma from the
Fars Province Cancer Registry and Mashad University Hospital were
reviewed and classified according to the new International Working Formulation
for clinical use. The cases fall into low-grade (35 male, 26 female),
intermediate-grade (61 male, 26 female), and high-grade (84 male, 26
female) groups. Each group includes several morphologic subtypes which
are discussed in detail. In general, lymphomas occurred more frequently in
two age groups: 5-20 and 45-65 years. High-grade lymphomas were more
common than either low or intermediate-grade types. Interestingly, a high
incidence of Burkitt's lymphoma (non-African type) was observed (58 of 290
cases), which occurred most commonly in children under 14 years of age,
with the abdomen as a preferred site. Follicular small cell cleaved lymphomas
(nodular PDL) were rare in our cases, in contrast to that which is
reported in other series. Several cases of lymphomas not included in the
Working Formulation such as intermediate lymphocytic lymphoma and its
follicular variant (Mantle Zone type) were also observed (15 male, 7 female).
