Successful Preservation of the Penis After en Bloc Resection of Locally Recurrent Rectal Cancer Involving the Left Crus of the Corpus Cavernosum and Corpus Spongiosum.

Introduction: We report a case of locally recurrent rectal cancer involving the penile base successfully treated with penis-preserving salvage surgery. Case Presentation: A 63-year-old man underwent abdominoperineal resection for locally advanced rectal cancer, followed by three metastasectomies for inguinal lymph node recurrences and a pulmonary metastasis. Thirty-four months later, intrapelvic recurrences involving the seminal vesicle, prostate, left crus of corpus cavernosum penis (CCP), and corpus spongiosum (CS) developed. Following chemotherapy and chemoradiotherapy, cystoprostatectomy with en bloc resection of the left proximal CCP and proximal CS was performed while preserving the right crus of CCP where the internal pudendal artery (IPA) ran. Surgical margins were negative. No intrapelvic recurrence had developed until his decease from pulmonary metastasis in postoperative month 23. Conclusion: The penis can be preserved even after the unilateral crus of the CCP and the proximal CS are partially resected when the contralateral IPA blood flow is viable.
