[Solitary mediastinal fibrous tumor complicated by hypoglycemic crises (Doege-Potter syndrome)].

Diagnostic and treatment algorithms for large mediastinal tumors are clear. However, long-term results are not always good. They largely depend on early diagnosis and morphological structure of tumor. Neoplasms may be asymptomatic for a long time, especially in case of slow growth. These tumors are usually diagnosed as soon as complications occur (for example, compression syndrome). Routine X-ray screening is rarer situation. Paraneoplastic syndromes are rare, and some ones are casuistic and unknown to surgical community. We describe the diagnosis and treatment of a patient with giant solitary mediastinal tumor complicated by hypoglycemic crises (Doege-Potter syndrome). This complication was life-threatening and required a multidisciplinary approach. Aggressive surgical approach cured the patient and returned her to normal lifestyle. The proposed algorithm for perioperative drug therapy was effective and deserves attention. This report will be useful for surgeons, oncologists, anesthesiologists, intensive care specialists and endocrinologists.
