Elastolytic giant cell granuloma (EGCG), also known as actinic granuloma, is an uncommon granulomatous dermatosis usually characterised by asymptomatic annular plaques on sun-exposed skin. Its aetiology is not fully elucidated, but actinic damage has been considered the main causal factor. Atypical variants with lesions in a non-photodistributed pattern are rare and often related to a systemic disorder, suggesting a more complex pathogenesis and demanding for a screening work-up. Herein, we report a case of an adult obese, diabetic woman presenting with a generalised pruritic papular eruption, histologically revealing an elastolytic giant cell granuloma, with a good response to treatment. In this case, the dermatosis was probably associated with her metabolic comorbidities.
