Retained foreign bodies (RFB) or Gossypibomas are rare causes of lumps. They can present with symptoms several years after surgery. We encountered the presentation of a patient with RFB or gossypiboma after total thyroidectomy and ablative session of I131 therapy with complaints of swelling on the left side of the neck since 2mths, discharge from post-operative drain site since one month associated with pain during deglutition. The Discovery of such a case of RFB in the neck providentially at an early stage, during the investigation of such a lump, is exceptional. We report such a singular case.
