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.

Intramuscular lipoma is a rare benign tumor. It refers to infiltrating lipoma because it originates between skeletal muscle abundles and infiltrates into the intramuscular septa. Kransdorf reported that the majority of lipomas were located in the trunk, head/neck, and lower extremity. In addition, in research by Kindlom et al., on 43 cases of muscular infiltrative lipoma, there was no case involving the chest wall. We report on a case of intramuscular lipoma on the anterior chest wall. The lesion was removed completely and histopathological findings showed that mature adipocytes had infiltrated serratus anterior muscle in a diffuse manner. After treatment, the patient has shown no complication or evidence of recurrence.
