MITF tumor syndrome
Alerts and Notices
Synopsis
Affected kindreds have been reported to have lighter skin phototypes, non-blue eye color, higher nevus count (mainly reticular pattern under dermoscopy), and onset of melanoma in those younger than 40 years. Some cohorts have demonstrated predominance of nevi greater than 5 mm in diameter, atypical nevi, multiple primary melanomas, and amelanotic melanomas. While some studies found an association with darker hair colors, others did not.
