آسیب شناسی و علائم بالینی 84 کودک مبتلا به لنفوم های غیر هوچکینی

Non-Hodgkin's lymphoma is the 3rd most common cancers in children. In the present study, to determine pathological and clinical features of this cancer, we reviewed records of 84 cases of non-Hodgkin's lymphoma who were admitted to Ali Asghar and Bahrami children hospitals from 1989 to 1996. 59% of cases had small non-cleaved cell (SNCC) subtype of disease. 15% were lymphoblastic and 5% diffuse large cell subtype. The most prevalent primary sites were abdomen and lymph nodes. The most prevalent symptoms were abdominal mass (34%), abdominal pain (37%) and cervcal lymphadenopathy (26%). Over half of our patients were small non-cleaved cell subtype, and further studies should be done to find out reasons for this unusual finding.
