Metanephric adenoma is an extremely rare tumor of the kidney. The clinical and anatomic characteristics are not yet well defined, but it is currently considered to be a benign tumor with a good prognosis, although recently two metastatic cases have been reported. Around 50% of cases are incidental findings, and symptoms include polycythemia, abdominal pain, hematuria and palpable mass. The morphological characteristics are similar to those of Wilms' tumor, suggesting a common embryological precursor. We present here the youngest girl yet to be reported with a diagnosis of metanephric adenoma.

Hemangioma is the most common benign tumor of liver and is often asymptomatic. Spontaneous rupture is rare but has a catastrophic outcome if not promptly managed. Emergent hepatic resection has been the treatment of choice but has high operative mortality. Preoperative transcatheter arterial embolization (TAE) can significantly improve outcome in such patients. We report a case of spontaneous rupture of giant hepatic hemangioma that presented with abdominal pain and shock due to hemoperitoneum. Patient was successfully managed by TAE, followed by tumor resection. TAE is an effective procedure in symptomatic hemangiomas, and should be considered in such high risk patients prior to surgery.

Focal nodular hyperplasia of the liver is a benign tumor that usually affects young women. Traditionally, its treatment in children has been conservative. As a result of its rarity in childhood, its differential diagnosis with other liver tumors is challenging. We present the case of a 5-year-old girl with a 1-week history of fever and abdominal pain. No definite diagnosis could be obtained after serial imaging and liver biopsy. As a result of uncertainty in the imaging and needle biopsy results, the patient underwent complete tumor resection. Pathology showed focal nodular hyperplasia that affected the right lobe of the liver. After surgery, the child was doing well at 24 months of follow-up.

Paragangliomas are rare tumors arising from extraadrenal chromaffin cells. We report a 43-year-old man who presented with abdominal pain. An abdominal computed tomography scan revealed a large retroperitoneal mass. During an endoscopic biopsy of this tumor, the patient experienced marked hemodynamic fluctuations with tachycardia and high blood pressure, and an extraadrenal pheochromocytoma was suspected. Measurements of plasma and urinary catecholamines and urinary total metanephrines ruled in the diagnosis. Echocardiography disclosed acute myocardial dysfunction that returned to normal after surgical resection of the paraganglioma. This report also underlines the importance of the anesthetic preparation and monitoring around the surgical procedure and the need of a long-term follow-up to detect malignant paraganglioma in the absence of histological criteria of benign tumor.

A rare case of Solitary fibrous tumor (SFT) of the pelvis is reported. A 76-years-old man presented with a low abdominal pain, acute urine retention and constipation. Imaging studies (US, CT MR) showed an 17 x 10 x 9 ovoid mass in the pelvis, dislocating bladder and rectum. Finally, trans-rectal needle biopsy suggested the diagnosis of SFT. En bloc excision of tumor and rectum (because of strong adhesions) was performed. Histological examination showed spindle and fibroblastic-like cells dispersed in collagenous areas with positive stains for CD34, bcl-2, CD99 and it confirmed diagnosis of SFT. No postoperative complications occurred, only vesico-sphincter dyssynergia was found by urodynamics. After 5 years, patient is disease-free. SFT is, usually, benign tumor with slow growth and excellent prognosis. Complete surgical resection is the only curative treatment. However, 10-15% of SFT are malignant and histological findings cannot always predict clinical behaviour. For this reason, careful and long term follow-up is necessary after surgery.

Lymphangioma of the colon is a relatively rare non-epithelial tumor and usually presents as a submucosal polypoid lesion. Many cases incidentally discovered are usually asymptomatic. However, they may present as abdominal pain or bleeding, and their resection is normally required. Lymphangioma itself is generally recognized as a benign tumor and no cases of malignant transformation have yet been reported, although its natural history is currently unknown. To the best of our knowledge, this study is the first to describe a case of spontaneous resolution in multiple colonic lymphangiomas without any specific treatment.

We present a case of a 42-year-old man with abdominal pain, obstructive jaundice and a mass in the second portion of the duodenum, near the papillary region. The patient was operated and the histological study of the specimen returned duodenal gangliocytic paraganglioma (a rare submucosal benign tumor of the duodenum). We also describe, after revision of the literature, the pathology, the diagnosis and its treatment.

Adenomyoma of the gastrointestinal tract is a rare benign tumor-like lesion. The small intestine is the second most frequent location, usually in the periampullary area, but the lesion also occurs in the jejunum and ileum. While adenomyoma of the Vaterian system is primarily diagnosed in adults, more than half of reported cases of jejunal and ileal adenomyoma have been diagnosed in pediatric patients. Adenomyoma of the periampullary area usually presents with biliary obstruction or abdominal pain, whereas jejunal and ileal adenomyoma usually presents with intussusception or is incidentally discovered during surgery or autopsy. Since endoscopic and radiological examination yields uncharacteristic findings, histopathological evaluation is important in adenomyoma diagnosis. Pathologically, adenomyoma consists of glandular structures of various sizes and interlacing smooth muscle bundles that surround the glandular elements. The pathogenesis of adenomyoma is generally considered to be either a form of hamartoma or a pancreatic heterotopia. Although limited resection is considered the most effective treatment, pancreaticoduodenectomy is often performed when the lesion occurs in the periampullary area due to preoperative misdiagnosis as a carcinoma. It is, therefore, important that clinicians and pathologists maintain current knowledge of the disease to avoid inaccurate diagnosis, which could lead to unnecessary surgery.

Hemangioma is the most common benign tumor of the liver and it is often asymptomatic. Spontaneous rupture of liver hemangiomas is a rare but potentially lethal complication. Emergent hepatic resection has been the treatment of choice but carries high operative morbidity and mortality. Recently, preoperative transcatheter arterial embolization (TAE) has been used successfully for the management of bleeding ruptured liver tumors and non-operative treatment of symptomatic giant liver hemangiomas. We report a case of spontaneous rupture of a giant hepatic hemangioma that presented with thoracic and abdominal pain and shock due to hemoperitoneum. Once proper diagnosis was made the patient was successfully managed by TAE, followed by conservative hepatic resection.

Lipomas of the colon are relatively rare benign tumors. Colo-colonic intussusception is an unusual complication of colonic lipoma. We report the case of a 79-year-old man who presented with spasmodic, self-limiting abdominal pain associated with rectal bleeding. Colonoscopy revealed a submucosal mass suggestive of a benign tumor but that was too large for endoscopic resection. CT scan demonstrated an endoluminal fatty mass in the transverse colon, typical of lipoma, and suggested colo-colonic intussusception due to the mass. The mass was removed laparoscopically. Recovery was uneventful.
