Report of a case: an intradural between roots capillary hemangioma of cauda equine

Background and Importance: cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. We report a case of the spinal intradural Cavernous angiomas of the lumbar spine

Case Presentation: a 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. In examinations, the patient was shown to have numbness in the anterior aspect of the right thigh in L2 territoryand a decrease in lower limb tendon reflexes. Magnetic resonance imaging [MRI] revealed at L1-L2 level, a well-defined intradural lesion in conusmedularis measuring about 18*12mm that shows high signal intensity in T1 images and low signal intensity in T2 images, which causes compression on the cauda roots. Laminectomy of L1-2 was performedfor tumor removal and intradural exploration revealed a small oval shape, brownish cystic like mass surrounded by adherent nerve roots. Complete removal of this tumor was accomplished. Histologic diagnosis wascapillary hemangioma. After operation, the patient's symptoms were improved

Conclusion: we experienced and reported a rare spinal intradural vascular tumor of the lumbar spine. Histologicdiagnosis was Cavernous angiomas

57 year old woman with polypoid gastric mass

A 57-year-old woman was referred with chief complaint of pallor and lethargy for 9 months. Laboratory investigation was notable for anemia and occult blood in the stool exam. Her past medical history was unremarkable. Endoscopy of the upper gastrointestinal tract showed a large fungative reddish mass measuring 7 x 6 cm in the body of the stomach and multiple variable size polyps in the antrum [figure 1]. The patient underwent hemi-gasterectomy. Billroth I. Gross examination of the stomach showed a large polypoid mass measuring 8x7x6 cm [figure 2] with erosive surface in some areas

Leishmania major in Tatera indica in Estahban, Southern Iran: microscopy, culture, isoenzyme and PCR

This study identifies the infected rodent hosts to Leishmania major in Estahban town, southern Iran during 2004-2005. The rodents were caught alive from April 2004 to April 2005 in Estahban town, south of Iran and examined for any skin lesion. An impression was provided from the tissues of feet, tail, ears and any patent lesion, stained with Giemsa and studied microscopically for the presence of amastigotes. All samplings were cultured at 25°C in rabbit blood agar and considered negative if no promastigotes were visible during a two months period. The parasites from any positive culture were cryopreserved in liquid nitrogen pending their identification in PCR and isoenzyme electrophoresis. The femoral bones were histologically and ultrastrucrurally studied. Among 13 captured rodents, 8 were Tatera indica [5 male and 3 female Indian gerbils] and 5 were Rattus rattus [3 males and 2 females]. Just one female T. indica was smear-positive for amastigotes in Mohmmad Abad village. This rodent was also found culture positive for leishmanial infection which was confirmed by PCR and enzyme electrophoresis. At histological and ultrastructural levels, many clusters of amastigotes were noticed in the foamy macrophages of the femoral bone bone marrow. T. indica was found for the first time in the area and can be one of the rodents to be a potential reservoir host of L. major. It was also shown that femoral bone marrow was the tissue of choice to confirm the presence of macrophages containing the amastigote form of the parasite
