Unusual Dermatological Manifestations of Gout: Review of Literature and a Case Report

BACKGROUND Gouty panniculitis is a rare clinical manifestation of gout, characterized by deposits of monosodium urate crystals in the hypodermis. Our aim was to describe atypical and rare clinical presentations of gouty tophi. METHODS We searched relevant English and Spanish literature of unusual gout manifestations using the following keywords: giant, gout, panniculitis, gouty panniculitis, gouty tophi, rare manifestations of gout, gouty, tophi, tophus, monosodium urate, uric acid, and unusual. Well-described case reports, case series, and review articles were evaluated and included in the literature review. RESULTS International literature has reported fewer than 10 cases of gouty panniculitis worldwide. In this case report, the patient presents a rare manifestation of gouty panniculitis, with typical joint injuries, gouty tophi in both lower and upper extremities, chronic gouty tophi in the nose, for which only 3 cases have been reported in literature, and great hypertrophy of adipose tissue in the lower back. CONCLUSIONS Tophi can be found in atypical locations, which increase morbidities and deformities caused by the disease. We report an interesting case of gouty panniculitis associated with great hypertrophy of the adipose tissue, a rare manifestation of gout, and unusual locations of tophi. These clinical manifestations in our patient have not been recorded before, which leads us to think that we are in the presence of a new dermatological manifestation of gout.
