The morbidity and mortality of small cell lung cancer (SCLC), an uncommon malignancy of the lung, remain high. Radiofrequency ablation (RFA) creates heat to destroy cancer cells and is usually used to treat non-SCLC, but not SCLC. ⋯ RFA can improve the prognosis of SCLC and should be considered for its treatment.

Case Reports
Ptosis as the only manifestation of diabetic superior division oculomotor nerve palsy: A case report.
Diabetic oculomotor nerve palsies, also called ischemic third nerve palsies, are the most common etiologic subset of oculomotor nerve palsy in adults. Diabetic oculomotor nerve palsies typically present with ptosis and diplopia, but pupillary function is often spared. The oculomotor nerve separates into superior division and inferior division, with the superior division innervating the superior rectus and levator palpebrae superioris. The diabetic oculomotor nerve palsy may affect isolated superior or inferior division of the oculomotor nerve, but diplopia usually exists. ⋯ From this case, we suggest that when evaluating patients with acute onset ptosis as the only manifestation, diabetic-vasculopathic neuropathy should be considered. This case also implies that the most interior portion of the third cranial nerve may consist of nerve fibers mainly innervating the levator palpebrae superioris.

Osteosarcoma is the most common malignant bone tumor in children and adolescents. Metastasis occurs early, the mortality rate is high, and the tumor results in a tremendous physical, mental, and economic burden on patients. Therefore, the treatment of osteosarcoma has been important for orthopedic surgeons. However, treatment has always been a difficult problem globally. ⋯ Our case indicated that limb osteosarcoma patients can undergo a limb salvage program of local arterial infusion chemotherapy, systemic intravenous chemotherapy, and curettage.

Case Reports
A coronary artery fistula having connection between 2 coronary arteries and the left ventricle: A case report.
Cases of coronary artery fistula having a connection with the cardiac cavity are rare. Here, we report a case in which 2 coronary arteries empty into the left ventricular cavity together. ⋯ Coronary artery fistula could be found incidentally on coronary angiography performed for varied reasons. Physicians must decide carefully whether the fistula needs to be treated in view of the clinical context.

Pulmonary alveolar proteinosis (PAP) is a rare lung disorder characterized by the abnormal accumulation of alveolar surfactant protein in alveolar spaces. Secondary PAP can result from myelodysplastic syndrome (MDS). ⋯ In conclusion, pulmonary physicians should suspect the possibility of secondary PAP when they encounter unexplained pulmonary infiltrates with some hematologic or infectious disease that shows diffuse bilateral GGO on an HRCT scan.
