Somatic malignancy arising from presacral or retroperitoneal primary teratoma is extremely rare. We report the case of a 37-year-old male patient with adenocarcinoma of respiratory type arising from primary presacral teratoma, but which first presented as anal fistula and rectal adenocarcinoma. The two tumors show the same morphology and immunophenotype (CK7-CK20+CDx2+). Malignant adenocarcinom...

Endometriosis-associated intestinal tumors represent the malignant transformation of gastrointestinal endometriosis. Approximately 50 cases have been reported in the literature. They are most commonly found among women aged 30-60 years, whereas exogenous hormone therapy and obesity are primary risk factors for the malignant transformation of endometriotic lesions. Clinical features simulate a p...

Barrett’s adenocarcinoma (BA) has seen a rapid increase in incidence throughout the Western world. The diagnosis of BA is often at an advanced stage and is generally associated with a poor prognosis and a mean survival of less than one year. Adenocarcinomas however do not arise de novo but follow an established sequence from Barrett’s metaplasia (BM) through dysplasia to neoplasia. EVorts to in...

In this research, softening and ratcheting behaviors of Ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. Experimental tests were performed by a servo-hydraulic INSTRON 8802 machine. The mechanical properties of specimens were determined according to ASTM E8...
