Overview

Acute lymphoblastic leukemia must be differentiated from other diseases such as acute myelogenous leukemia, hairy cell leukemia and malignant lymphoma.^[1]

Differential diagnosis

The following table differentiates acute lymphoblastic leukemia from other leukemias that may present with similar clinical features such as fever, fatigue, weight loss, recurrent infections and elevated leukocyte counts. The following are the differentials:

Disease	Etiology	Clinical Manifestation											Laboratory Findings			Gold standard diagnosis	Associated findings
		Demography	History	Symptoms				Signs					Laboratory Findings
		Demography	History	Constitutional symptoms	Weight	Bleeding	Abdominal Pain	Vital sign	Jaundice	LAP	Hepatosplenomegaly	Other	CBC	Histopathology	Other
Acute myelogenous leukemia^[2]^[3]	Clonal proliferation of malignant myeloid blast cells in the marrow Genetic abnormalities t(8;21), inv(16), and t(15;17)	The most common type of acute leukemia in adults Median age of 63 years old More in congenital disorders such as Down syndrome, Bloom syndrome	Smoking, previous chemotherapy or radiation therapy, myelodysplastic syndrome, and exposure to the chemical benzene	Fatigue	↓	+	–	Fever	–	Rare	Mild and asymptomatic	Bone tenderness Dyspnea Leukemia cutis Swelling of the gums Chloroma	Anemia Thrombocytopenia Leukocytosis or leukopenia	Leukemic blasts Positive Auer rods	NA	Flow cytometry > 20% blasts of myeloid lineage	Persistent or frequent infections Fatal within weeks or months if left untreated
