[Long-term fever as a first symptom of neoplasmatic process in young patients--case reports].

Unlabelled: Fever is a thermoregulation disorder with body temperature increased (above 38 degrees C). The most often accompanies infections, but it may also be a symptom of neoplasmatic disease.

Case Reports: In our paper we described 2 patients, who were admitted to the Department of Infectious Diseases and Neuroinfections with fever as a main symptom. Laboratory tests excluded the infection as causative agents of a long term fever. Wide spectrum diagnosis in both cases led to diagnosis of neoplasmatic disease. Presented cases indicate that in patents with long term fever, even in young age, neoplasmatic process should be taken into consideration.
