Libman-Sacks endocarditis is an important cause of embolic stroke in systemic lupus erythematosus, although the detailed pathogenesis of stroke remains unclear. We herein report two cases of stroke with Libman-Sacks endocarditis in which the emboli were retrieved by mechanical thrombectomy. ⋯ Immunohistochemistry showed immunoglobulin deposits in the embolus, suggesting that immunological mechanisms were involved in the growth of the embolus. A pathological analysis of the embolus retrieved by mechanical thrombectomy provided useful information on the etiology, leading to optimal treatment.

Necrotizing fasciitis (NF) is a life-threatening disease with high mortality and rapidly progressive clinical manifestations1. Early detection and surgical management coupled with antibiotic treatment are crucial for the survival, and the patient survival is heavily dependent on clinical decisions2,3. However, it is not widely known that NF does not always follow a typical clinical course, and there have been no case reports of NF following an atypical clinical course. ⋯ We encountered a challenging case presenting with an atypical clinical course. We herein report a 31-year-old man who followed a deteriorating biphasic-like clinical course and presented with extensive NF and streptococcal toxic shock syndrome due to Group A Streptococcus. This case serves to inform physicians of the existence of NF with an atypical and deteriorating biphasic-like clinical course, emphasizing the need for a careful evaluation of the patient condition.

During follow-up of a 60-year-old patient with dilated cardiomyopathy, a Holter electrocardiogram revealed monomorphic premature ventricular complexes (PVCs) accounting for 21-30% of total beats. Oral beta-blockers led to no improvement in PVC burden. The first radiofrequency catheter ablation attempt identified the PVC arising from the left ventricle summit communicating vein (CV) but failed to eliminate the PVC's origin. ⋯ The authors declare no competing interests.
