Papular pityriasis rosea.
Pityriasis rosea (PR) is a seasonal papulosquamous disorder that can be easily confused with a wide variety of similar appearing cutaneous disorders. This is particularly evident in its atypical papular form. We present a case report of atypical papular PR, along with a discussion of clinical presentation, histologic criteria, proposed etiology, and treatment options. Papular PR is atypical, presenting in a minority of patients, and may pose a diagnostic challenge. Being familiar with these atypical characteristics will facilitate accurate and timely diagnosis.
