We report a case of severe hypoglycemia in a 70-year old female initially admitted for resection of left sided solitary fibrous tumor of pleura. Investigation revealed true hypoglycemia, and DPS was diagnosed. The tumor was completely resected, after which no further hypoglycemic episodes were seen in 2 years follow-up. This is the first case of solitary fibrous tumor of pleura with DPS reported from Nepal. Keywords: insulin-like growth factor II, IGF-II, solitary fibrous tumor, hypoglycemia
