Abdominal lymph node metastasis from prostatic adenocarcinoma in a patient with esophageal squamous cell carcinoma

抄録

We report a case of prostate cancer that was discovered by lymph node metastasis to along the common hepatic arterial nodes. The patient was a 72-year-old man who had undergone esophagectomy as surgical treatment of esophageal cancer. The obtained specimen of along the common hepatic arterial lymph node showed adenocarcinoma, which was positive for prostate-specific antigen (PSA). The histological findings of the esophageal lesion demonstrated squamous cell carcinoma. Serum PSA was 350 ng/ml and prostate needle biopsy revealed adenocarcinoma. The patient commenced on total androgen blockade consisting of LH-RH analogue and bicalutamide (anti-androgen). However, the patient died due to recurrence of esophageal carcinoma.
