Masks of paraneoplastic syndrome in elderly patients.

Abstract

Paraneoplastic syndrome is a collection of clinical manifestations that occur as a result of a tumor process but are not related to direct tumor invasion or metastases. In elderly patients, this syndrome can have various "masks," mimicking rheumatological diseases such as rheumatoid arthritis, dermatomyositis, or polymyositis, among others. With aging, the frequency of oncological diseases increases, raising the risk of developing paraneoplastic conditions. However, their diagnosis is complicated by multiple comorbidities, age-related changes in the body, and nonspecific symptoms that delay the timely detection of oncological pathology. The aim of the study. To analyze the clinical features of paraneoplastic syndrome in elderly patients and identify the main "masks" of this syndrome that imitate rheumatological diseases.
