Which of the following lists represents the complete classic pentad of Leishmaniasis?

• A. Fever, Pancytopenia, Hypergammaglobulinemia
• B. Fever, Weight loss, Hepatosplenomegaly, Pancytopenia, Hypergammaglobulinemia
• C. Weight loss, Hepatosplenomegaly, Pancytopenia
• D. Fever, Weight loss, Hepatosplenomegaly, Pancytopenia

Answer: (B)

Visceral leishmaniasis presents with a five-part syndrome. The fever and weight loss show the systemic, chronic nature of the illness. Hepatosplenomegaly reflects infiltration and immune activation in the liver and spleen, causing enlargement. Pancytopenia arises from bone marrow involvement by the parasite and from hypersplenism, leading to reductions in red cells, white cells, and platelets. Hypergammaglobulinemia results from polyclonal B-cell activation in response to ongoing infection. When all five features appear together, they define the complete classic pentad. A list that includes all five components—fever, weight loss, hepatosplenomegaly, pancytopenia, and hypergammaglobulinemia—accurately represents the full presentation. Other options omit one or more elements, so they don’t capture the entire syndrome.
