Chondroid heterotopia in the omentum: A rare entity

Heterotopia is the occurrence of mature tissue at an abnormal location. Cartilaginous heterotopia is seen in several organs, but its occurrence in the omentum is extremely rare. Here, we report a case of incidental detection of chondroid heterotopia in the omentum, not associated with any intra-Abdominal malignancy, in a 35-year-old female during lower segment caesarean section. Omental nodule measured 1x1cm with a glistening surface and microscopy revealed nodules of mature hyaline cartilage surrounded by fibrous and adipose tissue. These may be due to the peritoneal response to previous intraoperative manipulation or could be from multipotent submesothelial rests.
