Spermatic cord is a rare metastatic site of colorectal cancer. We herein report a case of spermatic cord metastasis of a previous undiagnosed multifocal colon adenocarcinoma, which was clinically presented as a strangulated groin hernia.
- Inguinal Hernia
- Spermatic Cord
- Groin Hernia
Malignant lesions of spermatic cord, both primary and metastatic, are extremely uncommon. The proportion of metastatic neoplasms is very low, as these tumours account for less than 10% of malignant tumors of this site . The most common primary site for spermatic cord metastasis is gastrointestinal tract, followed by pancreas, prostate and kidneys [2, 3].
We herein describe the case of a 80-year-old male patient with multifocal colon adenocarcinoma, whose first presentation was a spermatic cord metastasis which was presented as strangulated inguinal hernia.
The first case of spermatic cord tumor was described in the middle of 19th century by Lesauvage . Since then a relative small number of spermatic cord neoplasms have been reported, with most of them being primary in nature. Metastatic lesions of spermatic cord are extremely rare and only case reports have been described. In a retrospective study by Dutt et al which included 13,500 autopsy specimens and 641 biopsy and orchiectomy specimens, only 2 metastatic lesions of spermatic cord, both from a gastric primary, were observed . Most commonly the primary origin of metastatic lesions of spermatic cord is gastrointestinal tract, followed by pancreas, prostate and kidneys [2, 3]. Colon is considered to be the main primary site originated from gastrointestinal tract , though in Japan the most frequent primary site is stomach .
Primary malignant neoplasms spread to spermatic cord mainly via hematogenous or lymphatic route. However, other routes of spread have also been described, including i) retrograde extension through the vas, either along its lumen, or direct extension via the wall of the vas, and ii) transperitoneal seeding through a patent tunica vaginalis . In our case the possibility of hematogenous or lymphatic spread could not be excluded; however, the presence of the cecal tumor in direct contact with the posterior wall of inguinal canal made the local tissue invasion the most likely mode of spread.
To the best of our knowledge, this is the first described case of a patient with spermatic cord metastasis mimicking strangulated hernia. Incarcerated or strangulated inguinal hernia is a common diagnosis for patients presenting with a painful and non-reducible groin mass. However, a plethora of different pathological entities may mimic an incarcerated or strangulated inguinal hernia, including Meckel's diverticulum, inflamed appendix, diverticulitis, ovulating ovary, liposarcoma of spermatic cord, spermatic cord hematoma and pancreatic pseudocyst [6, 7]. The consideration of these diseases in the differential diagnosis of a painful groin mass is critical as it may allow more precise diagnosis and more targeted treatment, especially in high risk patients.
Though rare, metastatic lesion of spermatic cord should be included in the differential diagnosis of a painful groin mass, especially in high risk patients, in order to achieve a more targeted treatment.
