The Silent Masquerader: Paroxysmal Nocturnal Hemoglobinuria Revealed.

Paroxysmal nocturnal hemoglobinuria (PNH), a rare acquired hematological disease, is identified by chronic hemolysis due to uncontrolled complement activation. We are reporting three cases-case 1: a 30-year-old male with hemolytic anemia and recurrent hospitalizations for blood transfusion who came with easy fatigability, breathlessness, jaundice, and pedal edema. Case 2: a 28-year-old female with hemolytic anemia who presented with fever, loose stools, reduced urine output, and hematuria. Case 3: a 37-year-old male presented with easy fatigability and jaundice and had splenomegaly on examination. All three cases were positive for different PNH clones on flow cytometry.
