Synopsis

Erythema papulosa semicircularis recidivans is an extremely rarely reported, recurrent dermatosis that presents with one or more centrifugally expanding plaques with onset in summer and resolution in autumn.

Plaques appear arcuate or semicircular with a border comprised of confluent, erythematous papules. They are most commonly found on the anterior trunk or flank but have been noted to occur on the neck and proximal extremities. Plaque size ranges from 5-25 cm.

The condition is exacerbated by excessive sweating and is usually accompanied by mild pruritus. In the few reported cases to date, the majority have been seen in males and individuals of East Asian ancestry. Adults younger than 40 years are most commonly affected.

The pathogenesis of this disease is unknown. Although most cases have not been associated with other diseases, at least one case has been associated with primary pancreatic lymphoma.
