5.2.2.2 Malassezia folliculitis

Malassezia (Pityrosporum) folliculitis commonly seen on the face and upper portion of the trunk has been confused with acne vulgaris [49]. A dilated hair follicle in the biopsy material was infiltrated by neutrophils and epithelioid cells forming suppurative granuloma. The patient's own serum reacted to Grocottpositive yeast-like fungi in the lesion (Figure 27) [21, 23]. Malassezial bodies, a commensal in the hair follicle of normal seborrheic skin sampled from another patient, were strongly labeled with the same serum.
