POSTSTREPTOCOCCAL GLOMERULONEPHRITIS WITH ATYPICAL SKIN RASH — DIFFERENTIAL DIAGNOSIS

Abstract: Poststreptococcal glomerulonephritis is a rare condition in developed countries. Skin rash is a common symptom associated with a variety of diseases. Due to non-specific features of poststreptococcal glomerulonephritis, the condition requires a broad differential diagnosis. A case is presented involving a 19-year old woman who was admitted to the hospital after pharyngeal infection, with symptoms indicative of acute kidney injury. The patient exhibited lower limb oedema, dyspnoea, hypertension and an atypical skin rash. The patient was diagnosed with poststreptococcal glomerulonephritis. Therapeutic interventions, including antibiotic therapy and symptomatic treatment, resulted in complete recovery. This case highlights the importance of accurately determining the etiology of symptoms, as skin rash is an uncommon manifestation in poststreptococcal glomerulonephritis. The patient's perspective and a thorough interview are of critical value. A broad differential diagnosis and multidisciplinary approach are crucial for establishing the correct diagnosis.
