A case report and differential diagnosis of pruritic pretibial skin lesions.

Journal: Acta Dermatovenerologica Alpina, Pannonica, Et Adriatica

Pretibial pruritic papular dermatitis (PPPD) is a clinical entity first described in 2006. The etiology is uncertain; however, gentle chronic rubbing is likely to be the reason for the skin reaction. Pretibial pruritic lesions may reflect many different systemic diseases and dermatoses. We present a 61-year-old patient with a 2-year history of pruritic pretibial xerosis, keratotic erythematous to brownish papules, and excoriations. Differential diagnosis excluded papular mucinosis, myxoedema, stasis dermatitis, lichen simplex chronicus, prurigo nodularis, lichen amyloidosis, and lichen planus. Regarding clinical-histological correlation, we confirmed a diagnosis of PPPD.
