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.

The association of colorectal cancer with ulcerative colitis (UC) is well-recognized. However, not much is known regarding the increased risk of extra-intestinal malignancies with UC. Several studies have revealed that patients with UC are at in-creased risk of hepatobiliary cancer, nonmelanoma skin cancer, and myeloid leukemia. A 41-year-old man was diagnosed with UC in 1993 and had three relapses over the next three years. Six months after the fourth remission, he developed pan-cytopenia and was diagnosed with acute promyelocytic leukemia (APL). He achieved complete remissions of APL through chemotherapies, and, since then, no recurrences of APL and UC were observed.

Idiopathic spontaneous intraperitoneal hemorrhage is a rare, often fatal condition; however, the patients present with nonspecific symptoms. Even after a comprehensive radiological examination and surgical exploration, the origin of hemorrhage often remains unclear. A 74-year-old woman with sudden abdominal pain, nausea, and vomiting was admitted to our hospital. She had no history of trauma. Computed tomography showed a huge hematoma along the small intestinal mesentery without evidence of visceral organ abnormality causing bleeding. The hematoma was completely removed by surgery and no origin of hemorrhage was detected. Herein, we report on a case of idiopathic spontaneous intraperitoneal hemorrhage.
