Segmental Acne versus Mosaic Conditions with Acne Lesions

“…Five out of the 10 cases of Happle-Tinschert syndrome identified so far (50.0%) featured comedo-like plugs on top of papulonodules (appearing histologically as basaloid follicular hamartomas) distributed along Blaschko lines [8,9,10,11,12]. …”
