Cytomorphology of some uncommon tumors of childhood and adolescence
- 22 Downloads
With the advent of newer adjuvant chemotheraputic regimes resulting in dramatic improvement in survival, it is mandatory to obtain quick correct diagnosis, which is provided by fine needle aspiration cytology (FNAC). Cytology of childhood tumors was studied to find any distinguishing features, which would help in arriving at a diagnosis.
Cytomorphology of 386 childhood and adolescent (0–19 years) tumors diagnosed between 1984 and 1993 were studied. Lipoma was the commonest benign tumor in 0–14 years age group. Fibroadenoma of the breast was the common benign tumor in adolescent (10–19 yrs) girls and pleomorphic adenoma in adolescent (15–19 yrs) boys. Wilms' tumor was the most frequent solid malignant tumor in preschool children and Hodgkin lymphoma, mixed cellularity in the school going age (5–19 yrs). Malignant tumors were more frequent (199).
In addition, some rare malignancies like hepatoblastoma, meningioma, ganglioneuroblastoma, adrenocortical carcinoma, clear cell sarcoma kidney and malignant histiocytosis were diagnosed. The cytological features and the differential diagnoses are discussed. It is possible to diagnose these uncommon tumors if particular attention is paid to the distinguishing cytomorphological features in correlation with clinicoradiological findings and cytochemistry.
