Dropsy is due to consumption of mustard oil contaminated with argemone oil. It usually occurs in epidemic outbreaks with acute manifestation of bilateral pitting edema erythema and local tenderness along with cardiac and respiratory problems in severe cases leading to death. We report an outbreak in a single joint family with major manifestation of bilateral pitting edema erythema and local tenderness in seven family members. Reported case was having serious clinical manifestation involving cardiac and respiratory systems. The diagnosis of epidemic dropsy should be strongly suspected if there is repeated clustering of bilateral pedal edema cases within a single family especially in an area consuming mustard oil.
