ABSTRACT
BACKGROUND:
Seborrheic dermatitis is a very common chronic inflammatory disease. Previous studies suggested that, Pityrosporum, lipophilic fungi, may play an important role in the pathogenesis of the disease.OBJECTIVE:
The purpose of this study was to investigate the disease clinically and mycologically for better understanding of the pathogenesis.METHODS:
Two hundred and one new patient.s with seborrheic dermatitis of the scalp and 67 norrnal subjects were obs!,rved clinically by the dermatologist and studied stat,istically by questionnaires. A mycologic study of Pityrosporum was also performed by direct smear.RESULTS:
Among a total of 201 patients wit,h seborrheic dermatitis, 72.6% had pityriasis sicca, 10.5% had pityr iasis steartoides and 16.9% had inflammatory seborrheic dermatitis. On clinical grading by the Kligman.. scale, grade III(slightly scaling) was the most common in the patients and 52.6% of the norma. subjects were below grade II (no scaling). Spores of Pityrosporum were observed in 76.7% of the patients and 91.5% of the normal subjects. The incidence of Pityrosporum was lower particularly in t,he patients with inflammatory seborrheic dermatitis t,han in other pa~tients groups.CONCLUSION:
According to the results of the study, it, is difficult to conclude that Pityrosporum is a main causative ager t of seborrheic dermatitis. In addition, it is thought t.hat further studies of the role of Pityrosporum in seborrheic dermatitis are needed.
