This 71-year-old Brazilian woman was admitted because of asthenia, palpitations, progressive breathlessness, and paroxysmal nocturnal dyspnea in the last three months. She also complained of a constrictive precordial pain irradiating to dorsum, fatigue and morning hand stiffness. Seven days before admission the cardiac scintigraphy showed discrete contractility changes. Medical antecedents were dermatosis over than 10 years, and rheumatism nearly 8 years; and intermittently used deflazacort, non-steroidal anti-inflammatory drug (NSAID), and methotrexate with good clinical response. She denied occurrence of fever, anorexia, loss of weight, and urinary changes; but presented one episode of melena first attributed to acute mucosal lesions due to medicines. However, both upper digestive endoscopy and colonoscopy evaluations were unremarkable. Physical examination revealed body mass index: 28 kg/m 2 ; and vital signs were temperature: 36.5°C, blood pressure: 110/70 mmHg, heart rate: 78 beats/min, and respiratory rate: 16 breaths/min. There were bilateral ulnar deviation of the wrists, painful hypertrophic changes in the interphalangeal joints and in the right sternoclavicular joint, and pain in the Achilles tendons. Moreover, bilateral palmar patches with lamellar desquamation; pitting, transverse grooves, and some transverse over curvature were detected in hands nails (Figure 1). Laboratory determinations showed hemoglobin: 11.5 g/dL, hematocrit: 37.1%, leukocytes: 5198/mm 3 , platelets: 105,000/mm 3 , erythrocyte sedimentation rate: 41 mm/h, C-reactive protein: 0.4 mg/dL, rheumatoid factor: 11 IU/mL, anti-nuclear antibody (immunofluorescence on HEp-2 cells): negative, triglycerides: 93 mg/dL, total cholesterol: 170 mg/dL, high-density lipoprotein cholesterol: 43 mg/dL, low-density lipoprotein cholesterol: 108 mg/dL, iron: 66 mcg/dL, albumin: 3.9 g/dL, globulins: 2.7 (α1: 0.2, α2: 0.5, β1: 0.6, β2: 0.5, γ: 0.9) g/dL, vitamin D: 14.6 ng/mL, immunoglobulin (Ig) G: 978 mg/dL, IgM: 177.9 mg/dL, transferrin: 357 mg/dL, transferrin saturation: 15%, glycated hemoglobin: 5.6%, potassium: 3.7 mmol/L, urea: 18.3 mg/dL, creatinine: 0.65 mg/dL, alanine aminotransferase: 46.6 IU/L, aspartate aminotransferase: 57.2 IU/L, thyroid-stimulating hormone: 1.53 mcIU/mL, free T4: 0.9 ng/dL, serologic tests for HIV and viral hepatitis: negative. The bone scintigraphy study showed hypercaptation in her shoulders, elbows,
ABSTRACTPsoriasis is a chronic inflammatory condition with variable changes on the skin and nails, sometimes associated with osteoarticular manifestations characterizing the psoriatic arthritis. This arthritis may precede, follow, or be concomitant with the skin lesions of psoriasis. Unsuspected psoriatic arthritis may be misdiagnosed by other seronegative spondyloarthritis, mainly in primary care attention, and ominous outcomes are related to late and inadequate management. Therefore, diagnostic exercises with base on significant clinical and radiological images might contribute to enhance the suspicion index about these...
