Chronic recurrent pruritic papular eruptions in which a specific diagnosis cannot be established becomes a baffling experience to the dermatologist. We have met adult male patients with chronic recurrent pruritic papular eruptions, but their clinicopathological features are not described in English language textbooks. Our purpose was to study the clinical and histological features of this entity and review the various existing taxonomy. We conducted a study of 20 patients over a six year period by taking histories, performing skin biopsies, screening patch tests, and doing immunofluorescence studies. The eruptions occurred exclusively in male adults and had a predilection for the trunk and proximal extremities. The lesions were characterized by severely pruritic, nonfollicular, monomorphic, erythematous urticarial papules. There was no evidence of atopic diathesis or history of insect bite. Most patients had normal levels of serum eosinophils and IgE. The predominant histopathologic finding was a presence of perivascular infiltration of mononuclear cells with eosinophils. The patients followed a chronic course of at least six months with waxing and waning; systemic corticosteroids were the only effective treatment. Finally, all other pruritic erythematous papular dermatoses were ruled out. These cases comprise a distinct entity that has previously been mentioned in a few reports. Clear definition of this entity with an appropriate designation is in order to avoid confusion among dermatologists, and we propose the disease name 'chronic papular dermatitis in adult men' as a variant of prurigo.
