Abstract
Benign dermoid cysts of the caecum are rare. We present a case of benign dermoid cyst of the caecum and discuss the various explanations of pathogenesis. Various possible explanations exist, including embryological sequestration, implantation following surgery, squamous metaplasia of enterogenous cysts and teratoma. In this case there was also a finding of intratubular germ cell neoplasia of one testis, detected on follow-up studies on the patient. The significance of this is discussed.
