Case: M, 42Y0M, Indian

DiseaseAssertion: VHL

FamilyInfo: No relevant family history.

CohortInfo: This retrospective study was conducted at Department of Endocrinology of a tertiary care health centre in Western India. Patients presented to our institute between 2008 and 2016 were included in the study.
