title: Annular erythema associated with anti-Ro/SS-A and anti-La/SS-B antibodies: a new case in a Hispanic patient.
abstract: We describe an 18 year-old male patient who was anti-Ro/SS-A and anti-La/SS-B positive and presented with recurrent annular plaques on the trunk, arms, face, and scalp with evidence of associated patchy alopecia. The skin biopsy revealed a superficial perivascular and periappendegeal lymphocytic infiltrate and focal areas of vacuolar alteration and smudging of the dermoepidermal junction. The patient also presented with a history of xerophthalmia. Skin lesions as well as sicca symptoms responded to antimalarial treatment with hydroxychloroquine. This case demonstrates a new case of annular erythema indistinguishable from those previously described in patients of Asian descent occurring in a Hispanic patient.
