AbstractTwenty five cases each of pityriasis versicolor (PV) and pityrosporum folliculitis (PF) were selected for this study. Histopathologically in PV, spores and hyphae in spaghetti and meatball appearance in stratum corneum, and perivascular mononuclear infiltrate were seen. In PF, spores were inside the dilated hair follicles filled with keratin, perifollicular and perivascular mononuclear infiltration were seen. Basket weave hyperkeratosis, edema and disruption of collagen were seen in 88% cases of PF and have not been reported earlier.
