Histology of malassezia folliculitis
The follicles are often plugged but there is minimal other epidermal change. There is a suppurative folliculitis, primarily involving the infundibular portions of the hair follicle (figures 1, 2, 3 show the same process at progressively higher magnification). PAS stain reveals numerous oval yeast-like organisms within the follicle and often in the surrounding dermis (figure 1, inset). The yeasts have been compared to a “clown with clown nose” as there is often small budding of the yeast-like forms (figure 1, arrow). The surrounding dermis shows a reactive inflammatory reaction which may be exuberant if there is follicular rupture.
