Follicular psoriasis: an under-reported entity. A report of five cases.

Follicular psoriasis is not rare in dermatological practice, although only a few cases have been reported. We describe five patients with follicular psoriasis, one man and four women. The patients ranged in age from 23 to 73 years. Lesions consisted of erythematous scaly follicular papules located on the trunk and extremities. Two patients had associated plaque-type psoriasis of the scalp. None had nail involvement at the time of diagnosis. Histological examination of several biopsy specimens revealed the changes of psoriasis in the follicular epithelium.
