Gossypiboma is derived from two Latin and Swahili words including gossypium (cotton) and boma [place of concealment] (1). It is a kind of retained foreign body (RFB) following surgery (2). It causes two types of reaction including exudative inflammatory reaction and aseptic fibrotic reaction. The first type causes reaction to the material of sponge and presents as a mass in the body. The second forms an abscess and results in early diagnosis leading to surgical removal (3).
