A case of extramammary Paget's disease of the axilla in an 84-year-old patient is presented. No underlying carcinoma was found and the lesion was treated successfully by wide local excision. Immunohistochemical staining showed nuclear immunoreactivity for c-myc and cytoplasmic staining for CEA, EMA, CAM 5.2, EGRF, c-erbB-2 and pan-cytokeratin in all the Paget cells. No immunoreactivity of the lesion was observed for S-100 protein, pan-ras, H-ras, K-ras, and p53 oncoproteins. Further research is needed to establish whether oncoprotein overexpression plays a role in the pathogenesis of extramammary Paget's disease and can be used as a diagnostic or prognostic marker.

Light, electron microscopy, polymerase chain reaction (PCR), and immunohistochemistry were used to reveal the proliferative, alterative processes of hepatic parenchymal cells, P 53, K-ras, B-raf, c-Kit, p 16, APC, immunoreactive proteins Ki-67, cytokeratins 9, 14, 20, EMA, c-erb B-2, CD-117, mutated p 53 and bcl-2 genes. P53, K-ras, B-raf, c-Kit, and p 16 gene mutations were detected in the liver of animals with experimental superinvasive opisthorchiasis (SO) and cholangiocellular carcinoma (CCC). Mutations of these genes were found in the plasma samples taken from SO patients. The CCC tissue from SO patients displayed expression of the following genes: p 53 (100.0%), p 53+B-raf (50.0%), K-ras+c-Kit (33.3%), K-ras+B-rafat more than 5 cm from the tumor in 2 cases. Following 2 years, target therapy (canglait, megamin, immunomodulators) leveled mutations in 91.25% of the patients with SO.
