title: [Signet ring cell carcinoma of the stomach--a case of diagnostic dilemma].
abstract: Inguinal lymphonodal metastases of an adenocarcinoma were diagnosed in a 40-year-old patient by ultrasound guided puncture. The leading symptom was elephantiasis preferentially of the right lower extremity. In addition, atypical mycobacteriosis was detected later on. The causal gastric cancer had not been identified during two years until the fourth gastroscopy assisted by endoscopic ultrasonography revealed the lesion. No regional lymph node metastases were found while distant metastases in terms of inguinal lymph nodes were already present.
