Immunohistochemically, both lesions are positive for MUC6 protein (a pyloric gland mucin marker), are negative for MUC5AC (a foveolar mucin marker), and demonstrate a very low proliferative activity index by Ki-67/MIB-1.
Divergent expression of MUC5AC, MUC6, MUC2, CD10, and CDX-2 in dysplasia and intramucosal adenocarcinomas with intestinal and foveolar morphology: is this evidence of distinct gastric and intestinal pathways to carcinogenesis in Barrett esophagus ?
The foveolar glands were elongated, irregular, and focally dilated.
However, typical features of portal hypertensive polyps reportedly include foveolar hyperplasia of the epithelium as well as proliferating, ectatic capillaries in the lamina propria; this indicates their portal hypertensive nature and distinguishes them from inflammatory polyps (Figure 4) [3, 7, 8,11,14].
However, sometimes they can show focal staining with MUC5A (a foveolar marker, positive in gastric foveolar-type adenomas, Figure 2(b)) and MUC1 (a pancreatobiliary marker, positive in biliary-type adenomas).
Inicialmente fue valorada en Centro Medico Nacional de Occidente del IMSS donde en la exploracion oftalmologica se documento: segmento anterior de ambos ojos sin alteraciones, fondoscopia de ojo derecho con vitreo claro que permitio valorar a la papila con forma, tamano y coloracion normales, con una excavacion de 0.3 con emergencia central de vasos y patron vascular conservado, se encontraron estrias que partian de papila en forma radiada en M1 y M3, area macular con arquitectura alterada a expensas de cambio de coloracion en patron de mancha por fuera de haz papilomacular y brillo foveolar presente, presencia de hiperpigmentacion del epitelio pigmentario retiniano (EPR) en haz papilomacular y plano retiniano sin lesiones.
Foveolar cells are severely dilated with regular dilation patterns.
Eyes with CME showed large cystic spaces in the foveolar and parafoveal region.
Mostly, the tumor occupied the submucosa, infiltrated into the deeper layers, and extended to broad foci in the mucosa expanding the lamina propria without involving the foveolar glands [Figure 2]c and [Figure 2]d.
Mucosa was characterized by the reduced height of surface epithelium, flattened epitheliocytes in both surface and foveolar epithelium with nuclei displacement in central parts of the cells, and preservation of clear cell boundaries.
