Corticotroph pituitary carcinomas are tumors, defined by the presence of distant metastases that determine their poor prognosis. The diagnosis and therapy of malignant corticotroph adenomas remains a clinical challenge. The molecular mechanisms of malignant transformation of pituitary adenomas are unclear, although they are believed to arise in an adenoma-to-carcinoma sequence. ...

Parathyroid adenoma with prominent lymphocytic infiltrates is very rare, with only 8 previously reported cases in the English scientific literature. Cases with prominent lymphocytic infiltrates of ectopic (mediastinal) parathyroid adenomas have not been reported. The prominent lymphocytic infiltration may make the diagnosis difficult on frozen sections, even on permanent histologic ...

We present an exceptional case of a giant urachal tumor, consisting of both villous adenoma and mucinous adenocarcinoma of the urachus. The tumor was incidentally discovered during investigations for renal failure. Initial transurethral biopsies showed only a villous adenoma of the urachus. Although the biopsies showed no malignancy, a radical ...

Microscopic colitis causes chronic watery diarrhea. Many cases may be induced by medications, and lansoprazole, a commonly used proton-pump inhibitor, has been associated with collagenous colitis and lymphocytic colitis, the two subtypes of microscopic colitis. Two cases of collagenous colitis associated with lansoprazole are reported, both in older female patients, ...

Pituitary adenomas without clinically active hypersecretion are summarized under the term non-functioning pituitary adenoma (NFPA). Since there are no specific serum markers, the differential diagnosis and treatment imply special difficulties. By using immunohistochemical methods we will have new insight into the nature and pathogenesis of these tumours. Ki-67 is a ...
