Neuroblastoma in uncommon age group - A case series diagnosed on cytology.

Background: Neuroblastoma is the most common extracranial malignant neoplasm in early childhood. It is rare in the adult population.

Aims And Objectives: We aimed to study the incidence of neuroblastoma in the uncommon age group diagnosed on cytology.

A rare cytogenetic presentation of acute myeloid leukemia (AML-M2).

Acute myeloid leukemia (AML) with t(8;21)(q22;q22) generating the AML1/ETO fusion gene on 8q22 is a distinct type of AML t(8;21) category (WHO)/AML-M2 (FAB), generally associated with a favourable prognosis. Variant additional chromosomal abnormalities are frequently reported. We report three adult cases of this category with unusual karyotype.
