To our knowledge, there have been no reports of right-sided infective endocarditis (RSIE) with ventricular free wall vegetation caused by Abiotrophia defectiva. We herein report a case of RSIE caused by A. defectiva with ventricular free wall vegetation in a 27-year-old man with ventricular septal defect (VSD). Computed tomography showed multiple bilateral pulmonary nodular shadows. ⋯ Blood culture revealed A. defectiva. These findings are consistent with a diagnosis of infective endocarditis and septic pulmonary embolism. Treatment with ceftriaxone and gentamicin and subsequent surgical VSD closure improved the patient's condition without recurrence.

Sudden Cardiac Arrest due to Spontaneous Coronary Artery Rupture - A Case Report with a Diagnostic Challenge.
Spontaneous coronary artery rupture (SCAR) is a rare, life-threatening disease, and the diagnosis is often challenging. We herein report a 70-year-old man who suffered sudden cardiac arrest due to SCAR with pericardial fluid. ⋯ A careful retrospective CAG review showed slight contrast spillage from the distal LCx. SCAR should be suspected in patients with unknown etiology of pericardial effusion, and careful inspection of CAG is necessary.

Delayed and Synchronous Recurrence of Breast Cancer Metastases in Multiple Organs: A Case Report.
The most common sites of breast cancer metastasis include the lymph nodes, bones, lungs, liver, and brain. Gastrointestinal tract metastasis is rarely seen, and hypopharyngeal metastasis is extremely rare. We herein report a case of late distant recurrence of breast cancer and synchronous metastasis to the hypopharynx, stomach, ileum, bones, and lymph nodes almost 24 years after surgery. To our knowledge, this is the first case of synchronous metastasis to the hypopharynx, gastrointestinal tract, and other organs, especially after a long interval following primary mastectomy.

An 82-year-old man with fever and back pain was referred to our hospital and was thus found to be thrombocytopenic. A bone marrow biopsy revealed the diffuse infiltration of poorly differentiated neuroendocrine carcinoma (NEC). Computed tomography revealed a large hepatic mass. ⋯ The patient rapidly deteriorated and died 10 days after presentation. An autopsy confirmed the diagnosis of primary hepatic NEC, with diffuse metastasis to the spleen, bone marrow, and systemic lymph nodes. This is an extremely rare case of NEC presenting with thrombocytopenia due to extensive bone marrow and splenic infiltration.

Primary cardiac lymphomas (PCLs) are extremely rare tumors with a poor prognosis. They usually involve the pericardium and the right side of the heart. ⋯ Multiple imaging modalities clearly demonstrated the tumors at the initial evaluation. The pathological diagnosis was diffuse large B-cell lymphoma.
