Spermatic cord (SC) tumor metastatic from gastric cancer (GC) is rare. Here we report a case of left SC metastasis and meanwhile perform a literature review to characterize this rare disease. A 72-year-old male presented with a palpable painful mass in the left groin after one year and a half of remnant GC resection. SC metastasis of signet-ring cell adenocarcinoma was confirmed by trans-inguinal biopsy, and palliative chemoradiotherapy was initiated. The disease remained stable within follow-up 10 months. A total of 27 GC patients with male sex cord metastasis were reviewed according to a literature search from January 1955 to March 2016. In such a cohort, the mean age was 58.3 (range, 23-72) years. The average time interval between primary GC and genital metastasis was 43.2 (range, 2-120) months in 16 (59.3%) metachronous cases, while nine (33.3%) synchronous cases reported. The average size of genital tumor was 3.8 (range, 2.1-9.0) cm in diameter. The major pathological characteristics were signet-ring cell (40.0%, 8/20) and poor differentiation (85.0%, 17/20), with right-side sex cord most commonly involved (48.1%). The incidence of genial metastasis was 74.1% in SC, with 40.7% for epididymis, 33.3% for testis, 14.8% for tunica vaginalis and 3.7% for scrotum. The one-year overall survival rate was 38.7%, with a median survival time of 12 months. Advanced GC metastatic to male sex cord is rare, with poor prognosis. For patients with GC history and groin discomfort or mass, metastatic adenocarcinoma should be suspected, followed by proper diagnosis and treatment.
