“…We conducted a literature search on PubMed regarding cases of colorectal cancer metastasizing to the adjacent testicular tissues and identified several relevant reports. This phenomenon is predominantly observed in elderly males, with mucinous adenocarcinoma being the primary histological type (2)(3)(4)(5)(6)(7). Herein, we present a case involving a young male patient who presented with scrotal effusion as the initial symptom.…”

Colorectal cancer, with the liver being the most common site of distant metastasis, followed by the lungs and bones. Although reports of metastasis to the testis exist, paratesticular metastasis is extremely rare. A 37-year-old male presented with scrotal swelling. Ultrasound revealed hydrocele of the tunica vaginalis. The patient underwent routine surgical treatment, and postoperative pathology of the tunica vaginalis indicated adenocarcinoma of gastrointestinal origin. Colonoscopic biopsy confirmed adenocarcinoma of the sigmoid colon. After six months of systemic therapy, tumor reduction surgery was performed in conjunction with tunica vaginalis excision. Postoperative pathology suggested histological similarity in both sites, with immunohistochemistry results supporting the diagnosis of sigmoid colon adenocarcinoma metastasizing to the tunica vaginalis. We conducted a literature review, summarizing and discussing clinical presentations, metastatic pathways, and diagnostic approaches.

Testicular metastasis 9 years after resection of primary descending colon cancer with simultaneous pulmonary metastasis: a case report

et al. 2023

Background Metastatic testicular cancer is rare. In particular, primary colorectal cancer rarely metastasizes to the testes. This study reports a case of testicular metastasis recurrence 9 years after the resection of a primary colorectal cancer and a simultaneous metastatic lung tumour. Case presentation A 69-year-old man underwent a laparoscopic left hemicolectomy for descending colon cancer. Preoperative computed tomography revealed a solitary left lung mass. Postoperative chemotherapy reduced the size of the lung mass, and 6 months after the primary resection, the patient underwent a left upper segmentectomy. Based on the pathological examination, he was diagnosed with pulmonary metastasis from colorectal cancer. After four courses of adjuvant chemotherapy, the patient was recurrence-free. However, 9 years and 6 months after the primary resection, he complained of discomfort in his left testicle. Physical examination revealed a left testicular mass. Since a malignancy was not excluded via imaging, left testicular resection was performed to confirm the diagnosis. The pathological diagnosis was testicular metastasis from colorectal cancer. The patient was followed up without medication, and remained healthy, without recurrence, 11 months postoperatively. Conclusions It is important to follow up with testicular metastasis in mind, although it is rare.

Background Colorectal carcinoma (CRC) is a common malignancy, frequently metastasizing to the liver, lungs, and regional lymph nodes. However, metastasis to the scrotum is exceedingly rare, with few cases reported in the literature. In this study, we present a series of five cases of colorectal carcinoma metastasizing to the scrotum, emphasizing their unusual clinical presentation and late recurrences. Methods We did a retrospective review of 7 years from 2015–2022 for cases of scrotal metastasis in cases of CRC. Results The means age in our study was 38 years (22–61 years) and the median time interval between the primary diagnosis and scrotal metastasis was 31.6 months (0-104 months). Case presentations included scrotal swelling initially misdiagnosed as a hydrocele (case 1), non-healing cutaneous ulcers (cases 3 and 5), a scrotal skin papilloma (case 4), and a cutaneous nodule (case 2). Conclusion This series of five cases highlights the rarity and diagnostic challenges associated with colorectal carcinoma metastasizing to the scrotum. The extended latency between primary tumor diagnosis and scrotal metastasis, coupled with atypical clinical presentations, underscores the importance of maintaining a high index of suspicion. Clinicians should be vigilant, especially when evaluating patients with a history of colorectal carcinoma, to promptly identify such uncommon metastatic sites.
