[A mixed form of mucocele of the colon].

The term mucocele is applied to an accumulation of mucus within a lumen lined with mucus-secreting epithelium as well as to the structure resulting from leakage of mucus into surrounding connective tissue. The case report is presented of a patient with a bizarre, mixed type of mucocele after perforation of a hemicolon retained 26 years previously, a clinical picture which could not be traced in the literature.
