DIAZ, M H et al. GRANULOMA ANULAR PERFORANTE: PATOLOGIA INUSUAL. Rev. argent. dermatol. [online]. 2020, vol.101, n.1, pp.21-30. ISSN 1851-300X.

Granuloma annulare is a chronic, benign, self-limiting, inflammatory dermatosis of unknown etiology.

There are numerous clinical variants within which is the perforating, unusual presentation.

The most histopathology characteristic of GA is the presence of palisading epithelioid histiocytes around areas of focal degeneration of collagen with mucin deposits. The perforating variety evidences transepidermal elimination of collagen tissue.

A 72 years-old, diabetes, dyslipidemic patient is presented with pruritic lessions on the dorsum of both hands, with the diagnosis of perforating granuloma annulare. I perform medical treatment with topical clobetasol, leaving an atrophic scar.

Keywords : Granuloma annulare; perforating annular granuloma; diabetes; dyslipidemia.
