Hemangioma of the small bowel. Case report.

avernous hemangioma is a very rare disease if located in the ileum, but not an uncommon lesion if it occurs in the large bowel. The Authors report a case of small bowel cavernous hemangioma, and consider clinical, diagnostic and therapeutic aspects for an exact evaluation of the lesion

[Morphological and biochemical study of the lipid components of the fetal aorta].

We made a biochemical and histochemical study of the lipidic component of intima of fetal aortas on 8 autopsy cases (7 +/- 2 months aged) arrived at our observation in the Pathology's Institute of II Faculty of Naples. We made a study with freeze-sections stained with Oil-Red 0 and after dissociation of the intima by the adventitia, it is valued biochemically the lipidic peroxidation studying the levels of malonyldialdehyde (MDA) like indirect marker of peroxidation. It is known that is present a lipidic component in the intima of fetal aorta whether intracellular or extracellular (Fig. 1, 2). Sometimes this component can accumulate until to determinate true lipidic striae. The aim of this study is a detection of MDA in lipids extracted from human fetal aortas. MDA levels was measured by Thiobarbituric method (TBA): lipids were extracted both intima and adventitia by Chloroform/methanol method, after surgery immediately. The results are expressed in nMoles/mg of lipids +/- Standard Deviation. Controls of spontaneous lipid peroxidation was take at a different times. It is known that in vitro incubation of LDL with cultured endothelial cells, smooth muscle cells or macrophages leads to peroxidation of LDL phospholipids and oxidatively modified LDL become atherogenic via foam cells production. In addition lipid peroxidation was formed by the direct peroxidation of unsaturated fatty acids and their esters are capable of further lipoperoxide production by oxygen free radical; chain reactions. In this context lipid peroxidation could be an important factor in the first stage of human pathophysiological development and this phenomenon may be related by an early free radical production

Adenosquamous carcinoma of the colon. Case report of an unusual type.

Primary adenosquamous carcinoma of the colon is a rare entity. Its prevalent site of origin is at the level of the proximal portion of the large bowel. The tumor presents in young patients and follows a highly aggressive course. We present an extremely unusual case of adenosquamous carcinoma in which the classical mucinous and signet-ring cell adenocarcinoma was associated with the squamous component. The prognosis of this rare neoplasm is very poor

Infection with Mycobacterium tuberculosis complicating a pulmonary sequestration.

Pulmonary sequestration is a relatively rare malformation. Infection with common pyogenes is a frequent feature in the evolution of this disease. We report a case of intralobar sequestration infected with Mycobacterium tuberculosis in the absence of any other site of tuberculous infection. The patient underwent surgical removal of the affected lobe and subsequent antituberculous chemotherapy. At 1-year follow-up his clinical status is excellent
