..In conclusion, in face of an important hyperprolactinaemia without any hypothalamic-pituitary mass, it remains important to search for an ectopic prolactin production, such as a PEComa...

..On follow-up after 3 months, dysphagia, fever, weight loss had disappeared and the ulcerated lesion of oesophagus had improved. The subsequent course of the patient is not known, since she was lost to follow-up...

..We should be aware of this entity as a differential diagnosis for inverted papilloma and well-differenciated adenocarcinoma. Fine histopathological analysis is necessary to avoid aggressive surgery for this benign lesion...

..0007). We showed that combined p53 and survivin immunostaining could be helpful in distinguishing patients with a high risk of tumor progression...

..In malformative cystic diseases, only MUC1 expression was retained; no expression of MUC6 and MUC3 was observed. These results implicate human mucin genes (MUC1, MUC3, and MUC6) in renal morphogenesis processes...

..Deregulation of mucin genes has been demonstrated in several epithelial neoplasms. In the kidney, MUC3 is expressed in normal convoluted tubules and in renal clear cell carcinoma...
