OBJECTIVETo study the clinicopathologic features, immunophenotype and differential diagnosis of plexiform angiomyxoid myofibroblastic tumor (PAMT) of the stomach.

METHODSThe clinical and pathologic findings of 3 cases of PAMT in the gastric antrum were retrospectively analyzed. Immunohistochemical study was carried out and the literature was reviewed.

RESULTSThe age of patients ranged from 31 to 47 years. The male-to-female ratio was 1:2. The clinical presentation included epigastric pain and distension. Endoscopically, the tumor mass protruded into the gastric cavity at the antrum and ranged from 4.5 cm to 8.0 cm in greatest dimension. One of the tumors studied was associated with surface ulceration. Histologically, the tumors were located in the gastric wall. They were composed of bland spindle cells and small vessels arranged in a plexiform or nodular pattern within a myxoid stroma. Immunohistochemical study showed that the spindle cells were consistently positive for smooth muscle actin and muscle-specific actin. There was focal staining for h-caldesmon, desmin in case 3 and focal positive for epithelial membrane antigen, CAM5.2 in case 1. Further, CD10 and progesterone receptor were positive in case 3.

CONCLUSIONSPAMT represents a rare novel mesenchymal tumor of the stomach, with a propensity of gastric antral involvement. The distinctive pathologic features help to differentiate this entity from other benign and malignant tumors.

OBJECTIVETo compare the angiogenesis in unstable and stable plaques and to investigate the potential role of neovessels in creating vulnerable sites for atherosclerotic plaques.

METHODSSpecimens of coronary arteries were obtained from 52 autopsy cases with acute coronary syndromes. Plaque morphology was studied by use of stained slides. 922 tissue blocks of late-stage lesions were classified into two groups: (1) unstable plaque (n = 153), the plaque was characterized by a large extracellular lipid core (more than 40% of the plaque area); (2) stable plaque (n = 769), lipid core less than 40% of the plaque area. Forty blocks were selected randomly from each group and serial sections were stained immunohistochemically with a polyclonal antibody against F VIII RAg. Computer-aided planimeter was used for quantitative analysis.

RESULTSIn unstable plaques, the occurrence of neovessels was more frequent and the neovessel density (number/mm(2)) was significantly increased as compared to that of stable plaques (frequency: 80.4% vs 66.6%, P < 0.01; shoulder: 22.16 +/- 19.96 vs 10.04 +/- 11.52, base: 21.68 +/- 20.44 vs 9.68 +/- 11.52, fibrous cap: 3.80 +/- 5.32 vs 1.48 +/- 2.28, P < 0.05). Most neovessels were located in the shoulder region and at the base of plaques.

CONCLUSIONSThese findings suggest that neovessels in coronary atherosclerotic plaques are closely associated with the decreased stabilization of the plaques.

OBJECTIVESTo analyze the relationship between oxidized low density lipoprotein (oxLDL), angiogenesis and stabilization of atherosclerotic plaques in human coronary arteries; and to investigate the role of oxLDL in creating vulnerable sites in atherosclerotic plaques.

METHODSSamples of coronary arteries were obtained at autopsies of 42 patients with acute coronary syndrome. Eighty randomly selected blocks were studied by immunohistochemistry using antibodies against oxLDL and endothelial cells (factor VIII). Computer-aided planimeter was used for quantitative analysis.

RESULTSIn unstable plaques, percentage of immunoreactive areas for oxLDL was significantly higher than that in stable plaques. Most of the oxLDL were located in shoulder region of these plaques, as compared to the fibrous cap and basal regions. The details of distribution of oxLDL were as follows: shoulder region (20.43 +/- 3.12 for unstable plaques and 17.65 +/- 4.22 for stable plaques), fibrous cap (4.77 +/- 2.03 for unstable plaque and 2.80 +/- 0.22 for stable plaques) and basal region (5.65 +/- 1.65 for unstable plaques and 3.22 +/- 1.02 for unstable plaques). OxLDL was also a main component in the lipid core. In the shoulder region, there was a significant positive correlation between neovascularization and oxLDL (r = 0.8247, P = 0.000).

CONCLUSIONSThe amount of oxLDL is significantly higher in unstable atherosclerotic plaques, especially over the shoulder region. OxLDL in coronary atherosclerotic plaques is thus an important factor in determining stabilization of the plaques. OxLDL may induce influx of inflammatory cells which subsequently leads to decreased plaque stabilization.
