**Question:** DIC is seen in -

A. Septicemia
B. Trauma
C. Eclampsia
D. Hematologic malignancies

**Core Concept:** DIC, or Disseminated Intravascular Coagulation, is a life-threatening condition characterized by a widespread activation of coagulation cascade leading to formation of fibrin strands within blood vessels. This results in vascular occlusion, organ dysfunction, and a high risk of bleeding.

**Why the Correct Answer is Right:** DIC is primarily seen in situations where there is widespread inflammation or tissue damage, leading to activation of coagulation cascade. In septicemia (A), this occurs due to bacterial endotoxins and release of pro-inflammatory cytokines, triggering clot formation. Trauma (B) also involves tissue damage and inflammation, thus increasing the risk of DIC.

**Why Each Wrong Option is Incorrect:**

C. Eclampsia (C) is a complication of preeclampsia, characterized by hypertension and proteinuria. Though it can lead to microthrombosis, it does not involve widespread inflammation or tissue damage, making it less likely to cause DIC compared to septicemia and trauma.

D. Hematologic malignancies (D) might cause hypercoagulability, but they generally do not cause widespread inflammation or tissue damage that characterizes DIC.

**Clinical Pearl:** DIC is a clinical syndrome and not a specific disease. Its presence in a patient should prompt a thorough evaluation for the underlying cause, as early identification and management of the triggering condition can improve patient outcomes.

**Correct Answer:** C. Eclampsia

DIC is primarily seen in conditions where there is widespread inflammation or tissue damage, such as septicemia and trauma (options A and B). Eclampsia (option C) can lead to microthrombosis due to hypertension and proteinuria, but it does not involve widespread inflammation or tissue damage. Hematologic malignancies (option D) might cause hypercoagulability but do not typically cause the systemic inflammation and tissue damage seen in DIC.
