Late-onset metastatic adenocarcinoma of the spermatic cord from primary gastric cancer

BACKGROUND Metastatic cancers of the paratesticular tissue are very rare; however, the most frequent primary site of spermatic cord metastasis is the gastrointestinal tract. CASE PRESENTATION We recently observed two cases of late-onset metastatic adenocarcinoma of the spermatic cord. Both patients complained of groin discomfort with a palpable mass in the scrotum and inguinal area. Radical orchiectomy and adjuvant chemotherapy were performed in both patients. Although the prognosis of patients with metastatic adenocarcinoma of the spermatic cord is typically poor, the prognosis of our patients was favorable after follow-up for 14 to 18 months. CONCLUSIONS In patients with groin discomfort or swelling and a history of gastric cancer, metastatic adenocarcinoma should be included in the differential diagnosis for early detection of tumors.
