Corpus luteal cyst rupture presents with acute pain abdomen, hemoperitoneum and features of shock. The condition clinically closely mimics acute rupture ectopic pregnancy but has negative urine pregnancy test. Massive hemoperitoneum requires urgent surgical exploration and achievement of hemostasis. Here is a case series describing 3 cases of corpus luteal cyst rupture in patients with diagnosed dengue fever presenting with features of acute abdomen with or without shock at emergency. All were managed surgically, did well in postoperative period, had transfusions of blood and blood products and finally discharged in satisfactory condition. The objective of this series is to highlight the importance of this condition as a differential diagnosis in patients with acute abdomen which is not much described in medical literature.
