TRUJILLO CORREA, María Cristina et al. Granulomatous interstitial dermatitis with plaques and arthritis in a teenager: Case report. Rev.Colomb.Reumatol. [online]. 2010, vol.17, n.1, pp.58-63. ISSN 0121-8123.

The clinical case report of a 14-year-old diabetic teenager with undifferentiated juvenile arthritis and 2- years history of skin-colored maculae and plaques is presented. Biopsy examination of a skin specimen showed findings of early interstitial granulomatous dermatitis. The patient was treated with hydroxicloroquine with partial response. Interstitial granulomatous dermatitis with plaques and arthritis is an idiopathic rare disease that usually affects young women. It is usually related to rheumatoid arthritis or another autoimmune disease. It represents a disorder that involves degeneration of collagen by immune complex-mediated formation and deposition on the endothelial surface. Prognosis is variable with remissions and exacerbations or spontaneous and complete remission of skin lesions.
