Exudative discoid and lichenoid chronic dermatosis (Sulzberger‐Garbe): presentation with a puzzling penile plaque*

AbstractObjective Report of two cases of exudative discoid and lichenoid dermatosis (Sulzberger‐Garbe), with typical penile lesions. Differential diagnosis of persistent penile plaques.Background Following remission of the generalized eruption of exudative discoid and lichenoid dermatosis (Sulzberger‐Garbe), it is not unusual to see a single remaining lesion localized on the penis. Since Sulzberger et al. (Sulzberger MB, Witten VH, Hunt JA. Puzzling persistent penile plaques. Arch Dermatol 1956:73:101‐109) reviewed dermatoses presenting with puzzling persistent penile plaques in 1955, further dermatoses have evolved as important differential diagnoses. Much controversy has arisen as to the justification of exudative discoid and lichenoid dermatosis (Sulzberger‐Garbe) as a disease entity.Conclusions Diagnosis of most cases of persistent plaques of dermatitis on the penis is possible with a careful examination of the entire skin, and a thorough history to discover past lesions. The possibility of malignancy makes a biopsy mandatory. Exudative discoid and lichenoid chronic dermatosis (Sulzberger‐Garbe) typically responds well to systemic steroids. Intrale‐sional triamcinolone acetonide has been demonstrated to be effective in the treatment of a persistent penile plaque in exudative discoid and lichenoid dermatosis (Sulzberger‐Garbe), and may be helpful in discontinuing or reducing systemic therapy to a level compatible with long‐term treatment.
