    Cavernous hemangioma of the rectum. Report of one case
    (SOC CIRUJANOS CHILE, 2010) Urrejola F, Gonzalo; Caselli M, Gino; Besa C, Cecilia; Torrealba F, Ignacio; Zuniga D, Alvaro M.
    We report a 41 years old male with a history of hematochezia since childhood. A colonoscopy showed a highly vascularized submucosal lesion extending from the pectinate line to the distal sigmoid colon. Magnetic resonance showed a thickening of rectal wall with multiple vascular structures and phleboliths. The lesion was excised surgically. The postoperative period was uneventful. The pathological report disclosed a lame rectal hemangioma.

    Retroperitoneal hydatid cyst: A common disease in a rare location
    (SOC CHILENA INFECTOLOGIA, 2010) Subercaseaux, Stephanie, V; Besa C, Cecilia; Burdiles O, Alvaro; Huete G, Alvaro; Contreras O, Oscar
    Echinococcal disease remains a major problem within some endemic areas. We report a case of a single primary echinococcal cyst located in the retroperitoneal space. A 54-year-old woman, born in a rural area of southern Chile, was admitted with a 3-month history of right hip pain and painful swelling of the gluteal region. Hidatid disease was confirmed with serologic test, radiological examinations and histo-pathology. There were no cysts in any other location. A percutaneous drainage was performed and antihelminthics were administered for 12 weeks and is now being closely followed up, with good response to therapy. Especially in the endemic areas hydatid cyst should be considered when evaluating retroperitoneal cystic masses.

    Ultrasound guided needle biopsy of the spleen. Review of 13 procedures
    (2010) Besa C, Cecilia; Teuber S, Cristobal; Huete G, Alvaro; O'Brien S, Andres; Cruz O, Francisco; Oyanedel Q, Roberto
    Background: Needle biopsies of the spleen were avoided due to the fear of bleeding in a highly vascularized organ. However their safety, even using 18 gauge needles, has been demonstrated. Aim: To report the experience with ultrasound guided needle biopsies of the spleen. Material and Methods: Retrospective review of records of ultrasound guided biopsies of the spleen using Tru-cut™ needles, performed between 2005 and 2009. Results: Thirteen procedures performed in 12 patients were identified. A specific diagnosis was achieved in nine (69%) procedures (lymphoma in four, melanoma in 2, sarcoma in 1, extremedullary erythropoiesis in one and splenic cryptococcosis in one. Two patients with negative results were subjected to a new biopsy, which yielded the diagnosis of lymphoma. A third patient was studied elsewhere, finding a malignant tumor. Two patients had complications, one had a vagal reaction and other had a perisplenic hematoma without clinical repercussion. Conclusions: Ultrasound guided needle biopsy of the spleen is a safe and useful procedure.
