Adult-Onset Still's Disease in a 28-Year-Old Man From Ghana

Adult-onset Still’s disease is a rare, autoinflammatory disease characterized by spiking fevers, arthritis, salmon-colored skin rash, and leukocytosis. It has been compared to systemic juvenile idiopathic arthritis because of its similar features but is much rarer than its pediatric counterpart. It is usually treated with corticosteroids and disease-modifying anti-rheumatic drugs. However, those with refractory disease are candidates for one of many biological therapies. We present the case of a 28-year-old man who was successfully managed with first-line steroid therapy.

A Novel Case of Yamaguchi Syndrome in a Hispanic Male

Yamaguchi syndrome or apical hypertrophic cardiomyopathy (HCM) is a unique variant of HCM. It is characterized by localized hypertrophy involving the left ventricular apex rather than the left ventricular septum. This syndrome has been traditionally seen in the Asian population, particularly those of Japanese descent. We present an interesting case of Yamaguchi syndrome seen in a Hispanic male.

A 48-year-old Hispanic male presented with epigastric tenderness and was admitted to the hospital for a non-ST-segment elevation myocardial infarction. His diagnostic catheterization revealed no significant coronary artery disease. However, his echocardiogram revealed apical hypertrophy and narrowing of the left ventricular cavity at the apex, consistent with Yamaguchi syndrome. Case reports such as ours serve to help clinicians broaden their differential diagnoses when approaching patients with acute coronary syndrome-like symptoms to include diagnoses such as Yamaguchi syndrome.
