[Spontaneous cholecysto-cutaneous fistula].

A recently observed personal case of spontaneous cholecystospontaneous fistula is reported. Factors leading to the relative infrequency of this form in recent years are described, and its rarity is demonstrated by the fact that the case reported was the first to be noted in about 1000 operations on the bile ducts. A brief account of the genesis, diagnosis and treatment of the condition is given. The interest of the case lay in the unusual site of the orifice (epigastrium).
