Non-Hodgkin's lymphoma very rarely involves the esophagus, occurring in less than 1% of patients with gastrointestinal lymphoma. A few cases of mucosa-associated lymphoid tissue (MALT) lymphoma of the esophagus have been reported in the English literature. To our knowledge, there has been no report of MALT lymphoma of the esophagus coexistent with bronchus-associated lymphoid tissue lymphoma (BALT) of the lung. This report details the radiological and clinical findings of this first concurrent case.

Diffuse hepatic hemangiomatosis without extrahepatic lesions is extremely rare in adults. A case of diffuse hepatic hemangiomatosis involving right lobe in a 50-year-old woman was presented. The hemangiomatosis was demonstrated by ultrasonography, computerized tomography (CT) and magnetic resonance image (MRI), and was confirmed histopathologically. Although diffuse hepatic hemangiomatosis is a rare disease in adults, its diagnosis should be considered in patients with diffuse tumor growth in one or both hepatic lobes and distinguished from malignant tumors. The present case is the first documented case of diffuse hepatic hemangiomatosis in an adult in Korea.

Synchronous primary lung cancers are relatively rare. The accurate diagnosis remains challenging, despite of the routine use of bronchoscopy and computed tomography (CT) of the chest. Herein we report a case of synchronous triple primary cancers of the right lung in a 72-year-old male patient in whom each tumor presented distinct CT imaging findings.

If a testicular cancer patient has a mass in the retroperitoneum, a metastasis is often the first suspicion, probably leading to improper diagnosis and overtreatment. Here we report a case of retroperitoneal schwannoma mimicking metastatic seminoma. A 29-year-old man, who had a history of seminoma, presented with a single retroperitoneal mass suspected to be a metastasis. Because the patient refused radiotherapy, 3 cycles of cisplatin, etoposide, and bleomycin were offered. Post-chemotherapy computed tomography scan revealed persistence of the retroperitoneal mass, with no change in tumor size or characteristics. Subsequently, retroperitoneal lymph node dissection was performed. The dissected tissue contained negative lymph nodes but a single mass in the attached fat. Pathology revealed retroperitoneal schwannoma, which was confirmed by immunohistochemistry. Thus, clinicians should be aware of retroperitoneal schwannoma and its distinction from metastatic seminoma to avoid misdiagnosis and ensure proper treatment.
