We described two adolescent girls with untreated, consistently annular, plaque-type psoriasis without pustules, a presentation that is to our knowledge, not previously described. No typical confluent plaque-type lesions were present. The plaques in our patients resembled other entities such as tinea corporis and erythema annulare centrifugum, given the erythematous, scaling borders and central clearing. Biopsy specimens from our patients showed features characteristic of psoriasis vulgaris. Both patients responded to combination therapy with calcipotriene and a mid-potency steroid. We conclude that primary annular plaque-type psoriasis shares features of both typical plaque-type and annular pustular psoriasis, suggesting that these entities represent a spectrum of psoriatic disease.
