Summary

Happle–Tinschert syndrome (HTS) is a rare syndrome characterized by segmentally arranged basaloid follicular hamartomas (BFH) associated with ipsilateral osseous, dental and cerebral abnormalities. Happle and Tinschert first reported this disorder in 2008, and three cases with similar presentations have since been reported. We report another case, that of a 40-year-old man, presenting with the characteristic clinical features of HTS.
