RESUMEN
Our objective in this review article is to present a clinical case of a patient with antisynthetase syndrome (ASyS) and provide an overview of the pathogenesis, classification criteria, antibody profiles, clinical features, and current knowledge of treatment options, focusing on interstitial lung disease (ILD). ASyS is an uncommon autoimmune disease with a heterogenous clinical presentation characterized by the presence of autoantibodies against an aminoacyl-tRNA synthetase and manifested by myositis, fever, inflammatory arthritis, Raynaud's phenomenon, mechanics hands, and ILD. ASyS-associated ILD (ASyS-ILD) is the most serious complication of ASyS, which may evolve to rapidly progressive ILD; therefore, it often requires thorough clinical and radiologic evaluation including recognition of a specific clinical phenotype associated with the antisynthetase antibodies (ASAbs) to guide therapeutic interventions.

Atrial myxomas, though the most common primary cardiac neoplasm, remain a rare disease occurring in about 0.03% of the population. While clinically benign, they are considered functionally malignant as they can cause life-threatening embolic events. Here we present a patient with a high-risk intermediate pulmonary embolism where bedside ultrasound revealed significant right ventricular dysfunction with an associated large left atrial mass. These findings combined with the patient's instability allowed her to be rushed to surgery for definitive treatment.
RESUMEN
Pulmonary talcosis is a rare pneumoconiosis that is difficult to diagnose and may progress to debilitating lung disease. Four types of talcosis are described in literature: talc-silicosis and talc-asbestosis secondary to inhalation in industry workers and talc-emboli in intravenous drug users that self-inject talc-containing oral tablets. Although found in common household products, talc is overlooked as a cause of pneumoconiosis. Talcosis caused by cosmetic face powder is even rarer. Here we discuss a woman in her 50s who developed talcosis from inhalation of cutaneous cosmetics two years prior, and how comprehensive history may be crucial in diagnosing this rare disease.
