Prognosis of the patients with lung cancer with lung-to-lung metastasis are known to be poor and frequently old aged persons with multiple nodules on imaging study abandon more invasive procedure including bronchoscopy and VATS (Videoassisted thoracoscopic surgery) to get tissue confirmation. Sjogren’s syndrome (SS) associated lung lesion mimicking lung cancer has a chance to have more favorable diseases including lymphoma. A 78-year-old woman with SS was admitted due to slowly progressive exertional dyspnea and multiple nodules on imaging study. She and her family gave up invasive diagnostic procedures at first due to old age but short term rapid change of dyspnea and nodules on chest CT brought out invasive procedures and diffuse large B-cell lymphoma was diagnosed. Dyspnea and nodules on imaging were improved after R-CHOP chemotherapy.

Toxocariasis is an illness of humans caused by roundworm. Toxocara species are commonly found in dogs and cats. Humans are accidental hosts. There are two routes of infection. One route is the ingestion of infected eggs, and the other route is the ingestion of an infected paratenic host. Clinical manifestations vary from asymptomatic infection to severe organ failure. In most cases, the patients are asymptomatic and the disease is self-limited. Thus, patients with mild symptoms do not require treatment. However we report on cases of patients with asymptomatic hepatic nodules who were treated to exclude malig-nant disease.
