[Co-occurrence of Whipple's disease and hyperparathyroidism - coincidence or causal relationship?].

Whipple's disease is a rare infectious disease with multiple clinical manifestations. The disease is named after George Hoyt Whipple, who first recorded the illness in 1907 after conducting the autopsy of a 36-year-old man with weight loss, diarrhea, and arthritis. Under the microscope, Whipple discovered a rod-shaped bacterium in the patient's intestinal wall, which was not confirmed as a new bacterial species until 1992, when it was named Tropheryma whipplei.

History: A 34-year-old previously healthy man presented to his general practitioner with nocturnal sweating, feeling full and a weight loss of 6 kg in three months. Over a period of one year clubbing of the fingers had developed and alopecia areata had been noted six months before the diagnosis was established.

Investigations And Diagnosis: Out-patient sonography revealed two large, partly cystic-necrotic space-occupying lesions in the liver.
