Abstract
Cryptococosis is a general term for subacute or chronic infectious disease caused by Cryptococcus neoformans. This disease can affect almost any organ of the body, but more frequently involves the central nervous system and respiratory organs, rarely involving the digestive tract. We report the clinical course of a 66-year-old male patient with mesocolon cryptococcosis. The patient visited the National Ohkura Hospital with a complaint of mass in the right hypogastric region. From the radiological findings, a benign mesenteric tumor was suspected and, accordingly, laparotomy was performed.
The tumor was present in a region between the ascending and transverse mesocolon and was diagnosed pathohistologically as a cyst that had formed due to Cryptococcus. The postoperative course was favorable but the patient died of gastric carcinoma ten years later.
No lesions of cryptococcosis were observed at autopsy.
