Abstract
Background: Cutaneous calcinosis, defined as the presence of benign and progressive calcium salt deposits at the subcutaneous level as a result of hypercalcemia and normocalcemia, is classified into four types according to the pathophysiological mechanism that generates it: dystrophic, metastatic, iatrogenic and idiopathic calcinosis.
Purpose: The aim of this manuscript is to present the case of a patient with superinfected cutaneous calcinosis.
Case presentation: A 52-year-old male patient with a history of gouty arthropathy and renal failure with a clinical picture of superinfected cutaneous calcinosis without hypercalcemia, of a metastatic type, given the history of chronic nephropathy without previous lesions in subcutaneous tissue or medical interventions that justify it.
Discussion and conclusion: The present case involves a patient with multiple comorbidities and polypharmacy, which is associated with cutaneous calcinosis. The clinical and paraclinical findings confirmed the presence of superinfected tophi, along with a picture of pneumonia. Likewise, a renal and urinary tract ultrasound was performed, which identified the presence of nephrocalcinosis. Given the history of renal failure, it was considered that this could be the etiology of metastatic cutaneous calcinosis, which in turn caused the skin lesions on the upper and lower limbs, which became superinfected. The management of this patient was based on antibiotic therapy and uricosurics.
