Lipomas are the most common mesenchymal benign tumor of the colon. They are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. The diagnosis can be made by colonoscopy, barium enema examination, and by computed tomography (CT). We have reported a case of large submucosal lipoma of the ascending colon with intestinal obstruction. At laparotomy there was an intussusception descending colon, and subtotal colectomy was performed.

Adenomatoid tumors are relatively uncommon benign neoplasms of mesothelial origin, usually occurring in the male and female genital tracts. Rare extragenital adenomatoid tumors have been identified in the adrenal glands, heart, mesentery, pleura, and lymph nodes. In the adrenal gland, adenomatoid tumors may pose a diagnostic challenge. The differential diagnosis includes adrenocortical carcinoma and metastatic carcinoma, especially signet ring cell carcinoma. Because of its glandular pattern, an adenomatoid tumor may be confused with an adenocarcinoma. We present 3 cases of adrenal adenomatoid tumors, including one with a concurrent large hemorrhagic vascular adrenal cyst. The adenomatoid tumors were unilateral, appeared solid and white, and varied from 1.7 to 4.2 cm in diameter. They occurred in 3 male patients aged 33, 33, and 46 years. One patient presented with abdominal pain due to the presence of a concurrent large adrenal cyst. The tumor was an incidental radiological finding in another case and was discovered during the course of a workup for hypertension in the third case. The light microscopic appearances were consistent with those of typical adenomatoid tumors. Immunohistochemical stains for calretinin and cytokeratin 5/6 were positive, confirming the tumors' mesothelial origin. Ultrastructural studies performed in 2 cases revealed microvilli and desmosomes. Follow-up showed no evidence of recurrence or metastasis. In our experience, the key to the diagnosis of this rare benign tumor is to consider adenomatoid tumor in the differential diagnosis of any glandular tumor occurring in the adrenal gland.

Angiomyolipomas are benign mesenchymal tumors, but those that arise from the small intestine are exceedingly rare. We report on a 48-year-old woman who had an ileal angiomyolipoma, who presented clinically with vague abdominal pain and bloody stool. Small-bowel intussusception was shown on an abdominal computed tomography (CT) scan. We discuss the clinical manifestations and clinicopathological and immunohistochemical findings of this benign tumor which appeared in this rare location.

Mesenteric fibromatosis (MF) is a rare, benign tumor commonly associated with Gardner's syndrome. The signs and symptoms in patients with MF are insidious. Patients may present with abdominal pain or discomfort when the tumors reach large sizes, which is typical at the time of diagnosis. Differentiating MF from other neoplasms such as gastrointestinal stromal tumors may present a diagnostic dilemma, especially in patients without any history of familial adenomatous polyposis. In the present report, we discuss a young girl who presented with MF. A pertinent review of the literature is also presented. This case is peculiar in that MF presented at a young age in a patient without history of familial adenomatous polyposis and occurred in the omentum with local invasion to the stomach.

Hepatic cavernous hemangioma is the most common benign tumor of the liver. Appropriate management of this tumor remains a controversial topic. We have accumulated a number of cases with successful management of local hepatic tumors. Here we report a case where we performed an ultrasound-guided percutaneous radiofrequency ablation for the treatment of a symptomatic hemangioma. A 36-year-old female patient visited Kyungpook National University Hospital because of persistent right upper abdominal pain caused by an enlarging hemangioma. After two sessions of radiofrequency ablation, the hemangioma was significantly reduced in size. After 36 months, a follow-up abdominal CT revealed remarkably diminished necrotic areas of ablated hemangioma. The size of hemangioma was decreased to almost one third of the original longitudinal diameter. The patient remains asymptomatic in regards to the hemangioma.

Chorioangioma is a benign tumor ot aberrant vessels originated from the chorion. This is a case study of a 22 year-old woman presented at 22 weeks of her first gestation with polyhydramnios and a sonographic finding consistent with placental chorioangioma. The fetus developed hydrops two weeks later. After three more days the patient was admitted due to abdominal pain and vaginal bleeding. The membranes ruptured spontaneously. Five hours from admission she delivered spontaneously a dead 1450 grams male abortus. Uterine revision was performed due to incomplete placental expulsion. A solid mass was removed during the procedure. The mass was sent to pathology and was diagnosed as placental chorioangioma. Large chorioangioma require careful follow-up due to the possibility of rapid deterioration in fetal condition.

Angioleiomyoma is a benign mesenchymal neoplasm composed of smooth muscle cells and thick-walled vessels. It is usually found in the skin of the lower extremities. Angioleiomyoma is a very rare tumor among the ever-expanding repertoire of growth variants described in benign uterine leiomyoma. More rare is a solitary tumor of the broad ligament. Thus angioleiomyoma of the broad ligament is an extremely rare benign tumor of the female pelvis. In this report a 52-year-old woman with a one-year history of abdominal pain was admitted to our hospital. Gynaecological and ultrasonography exams showed a large mass with increased vascularization in the right adnexal region. The patient underwent total hysterectomy and bilateral salpingo-oophorectomy. The site of the benign mass was the left broad ligament of the uterus. On pathologic examination of the specimen, the tumor was diagnosed as angioleiomyoma. We present a case of angioleiomyoma of the broad ligament because of its extreme rarity and the large size of the tumor.

Inflammatory myofibroblastic tumor (IMT) is a very rare benign tumor composed of myofibroblastic spindle cells of uncertain etiology, which can occur at any age and affect any organ system. More and more cases of IMT in children have been described in pediatric literature in recent years. However, this tumor occurring intraabdominally in children has rarely been reported in Taiwan. Here we present a 1-year-9-month-old boy who had fever and abdominal pain only for 2 days, symptoms mimicking acute abdomen. After imaging study, a huge tumor nearly 10 cm in diameter was incidentally found over the right abdomen with unknown origin and nature. After surgical removal of the tumor, IMT was confirmed by the pathological findings. It is very difficult to make an accurate preoperative diagnosis on this tumor according to past experience, so the role of pathological diagnosis with immunohistochemical study becomes important. This case illustrates that IMT should be considered as a possible cause of intra-abdominal mass in children who have fever of unknown origin.

Hemolymphangioma of the pancreas is a very rare benign tumor. There were only five reports of this disease until March 2008. Herein, we report a case of hemolymphangioma of the pancreas with gastrointestinal bleeding due to duodenal invasion. A 53-year-old man had been admitted a referral hospital because of severe anemia due to gastrointestinal bleeding in December 2005. He was then transferred to our institute with a diagnosis of a tumor of the head of the pancreas with duodenal invasion in January 2006. No abnormalities were revealed except for anemia in laboratory data including CEA and CA19-9. Gastrointestinal endoscopy revealed bleeding at the duodenum. Computed tomography also demonstrated a heterogenous mass at the pancreatic head and suspected invasion to the duodenal wall. Ultrasonography showed a huge mass at the pancreatic head with a mixture of high and low echoic areas. Pylorous-preserving pancreatoduodenectomy was performed. The pancreatic tumor was soft and had invaded to the duodenum. The pathological diagnosis was a hemolymphangioma of the pancreas invaded to the duodenum. His postoperative course was uneventful and he was discharged on the 26th d after surgery. Hemolymphangioma of the pancreas is a very rare benign tumor. In a literature review until March 2008, we found five case reports. Major symptoms are abdominal pain and distension due to the enlarged tumor. However, we experienced a case of hemolymphangioma of the pancreas with gastrointestinal bleeding due to invasion to the duodenum. This disease is a very rare entity, but should be considered when patients have gastrointestinal bleeding.

Lymphangioma is an uncommon malformation of lymphatic system. Multiple colonic lymphangioma named as lymphangiomatosis is considered an extremely rare disease. Although lymphangioma is a benign tumor and most colonic lymphangiomas do not cause symptoms and do not require treatment, resection of lymphangioma is necessary in the presence of symptoms such as abdominal pain, bleeding, intussusceptions. We report a case of colonic lymphangiomatosis in a man who presented with abdominal discomfort and anemia, which was diagnosed and treated with endoscopic snare polypectomy.
