Lumboischialgia as the first sign of stomach cancer.

: The paper reports on a case of a seventy-three-year-old male patient, whose disease was initially manifested by severe low back pain and lumboischialgia of the right leg as the first and only, and later, the leading symptom of disseminated adenocarcinoma of the stomach. The unusual presentation of stomach cancer confirms the necessity of simultaneous treatment of pain and determination of its etiology. It also indicates the need for re-evaluation of diagnosis when there is no favorable clinical effect of applied therapy.
