[Unmasking of Whipples disease after start of prednisolone therapy].

Whipples disease (WD) is a rare infectious disease with an annual incidence of 1-6:10.000.000. It is mostly found in middle aged, Caucasian males. The causative bacterial agent Tropheryma whipplei (TW) is common, but only few infected with TW develop actual WD pointing to host factors as essential. We present a case story of classic WD seen in a 48-year-old man presumed to have sarcoidosis and therefore treated with prednisolone which caused WD to flare up and ultimately unmask the disease.

[Lymphomas found by endoscopic screening for colorectal cancer].

While performing the screening programme for colorectal cancer in Denmark, some cases of adenomas have been found. By histological analysis they were shown to be lymphomas. In this case report, two such cases are described. Screening is the subject of much debate. These cases are relevant because they showthat malignant diseases, which the program was not designed to identify, were found. When debating screening it should be taken into consideration, that secondary diseases, with the potential for earlier diagnostics and potentially better prognosis may be detected.
