Acute lymphoblastic leukaemia with giant intracytoplasmic inclusion--a case report.

ABSTRACT

Acute Lymphoblastic Leukaemia (ALL) with intracytoplasmic inclusions is a rare and unusual subtype of acute leukaemia. Here we describe a case of ALL with intracytoplasmic inclusions in an adult female. These inclusions stained negative for Myeloperoxidase (MPO), Sudan Black B (SBB) and Alpha-naphthyl acetate estarase (ANAE) and positive for Periodic Acid Schiff (PAS). This case is being presented for its unusual occurrence and to recognise the characteristics of this subtype of ALL to avoid a misdiagnosis of AML (Acute Myeloid Leukaemia).
