Metastatic involvement of the penis is relatively infrequent. Metastasis of transitional cell carcinoma (TCC) is extremely rare. We report a case of bladder TCC with metastases to the penis that spares the urethra - a finding that, to the best of our knowledge, has not been previously reported. Of the documented mechanisms of metastatic transmission to the penis, we suspect the cause was retrograde lymphatic spread. In our case, a 59-year-old male presented to our clinic initially with phimosis and later developed gross hematuria...

Erectile dysfunction (ED) associated with type 2 diabetes mellitus (T2DM) involves dysfunctional nitric oxide (NO) signaling and increased oxidative stress in the penis. However, the mechanisms of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS) dysregulation, and the sources of oxidative stress, are not well defined, particularly at the human level. The objective of this study was to define whether uncoupled eNOS and nNOS, and NADPH oxidase upregulation, contribute to the pathogenesis of ED in T2DM men...

AIMS: Penile cancer is a rare malignancy in Western countries. The management guidelines are mainly derived from retrospective studies as there are no randomised trials. The primary objective of this study was to assess patterns of practice and outcomes of penile squamous cell carcinoma in Ontario. Secondary objectives included examining trends in incidence, pathological characteristics and prognostic factors. MATERIALS AND METHODS: All patients diagnosed with penile cancer between 2000 and 2010 were identified from the Ontario Cancer Registry and all available pathology reports related to penile cancer during this period were reviewed...

REVIEW
Ahmed T Hadidi
: The evolution of hypospadias surgery can be classified under 3 periods that were closely related to advances in surgical instruments, introduction of anesthesia, and newer suture materials. Stretching dominated the early period, tunneling during the Middle Ages, and flaps during the modern period. Suture materials have included at various time silver wires, horsehair, and stainless steel. Examination and translation of the original manuscripts showed that Galen recommended stretching and suturing of glanular hypospadias and not amputation or partial penectomy as has been currently reported...

INTRODUCTION & OBJECTIVE: The non-invasive nature of penile intraepithelial neoplasia (PeIN) allows for curative penile sparing therapy and is recommended, in their guidelines, by the European Association of Urology (EAU). Treatment options include topical chemotherapy, immunotherapy, laser treatment, photodynamic therapy and surgical excision. Our primary aim was to evaluate the outcome of carbon dioxide (CO2) laser treatment of penile intraepithelial neoplasia. METHODS: A retrospective review of 47 patients who underwent CO2 laser ablation of PeIN, from May 2008 to June 2015, in our tertiary referral centre was performed...

A 70-year-old man was referred to our department for further examination and treatment of a painless penile mass of about 2cm. The patient first noticed the mass onlya few weeks before presentation. Diagnostic biopsy was interpreted as leiomyosarcoma. Through systemic examinations the clinical stage of his disease was diagnosed as cT2N0M0 and we performed total penectomy. Histopathological examination for the totallyresected tissue disclosed the concomitant presence of regions compatible to squamous cell carcinoma and the results of immunohistochemistrywere compatible with the diagnosis of squamous cell carcinoma, sarcomatoid subtype of the penis...

Erythroplasia of Queyrat (EQ) is a rare disease involving the mucosal and transitional surfaces of the penis. Effective treatment is necessary to minimize progression to squamous cell carcinoma. The standard therapy for EQ, partial or radical penectomy, is invasive; photodynamic therapy (PDT) may be an effective, non-surgical tissue-sparing option. We report the case of a 67-year-old patient with long-standing EQ who was successfully treated with methyl aminolevulinate-PDT (MAL-PDT). A complete clinical response, confirmed by incisional biopsy, was achieved after five sessions of every-other-week treatment...

BACKGROUND: Urethral strictures or fistulas are common complications after phalloplasty. Neourethral defects pose a difficult reconstructive challenge using standard techniques as there is generally insufficient ventral tissue to support a graft urethroplasty. We report our experience with local fasciocutaneous flaps for support of ventrally-placed buccal mucosal grafts (BMGs) in phalloplasty. METHODS: A retrospective review of patients who underwent phalloplasty and subsequently required revision urethroplasty using BMGs between 2011 and 2015 was completed...

Penile metastases are rare in colorectal cancer. We report the first case of such a recurrence in a patient who had undergone an extralevator abdominoperineal resection with vertical rectus abdominis myocutaneous flap perineal reconstruction. The patient was treated with curative intent by total penectomy.

REVIEW
Juanita Crook
Squamous cell cancer of the penis is a radiocurable malignancy all too often managed solely by partial or total penectomy. Effective management of the primary tumor while preserving penile morphology and function is a priority. External radiotherapy and brachytherapy have a role to play in the definitive management of the primary tumor. Surgical nodal staging remains a cornerstone of management because it is the strongest predictor of survival, and inguinal status determines pelvic management. Postoperative radiotherapy of the regional nodes for high-risk pathology is indicated...

Penile-preserving surgery offers a revolutionary alternative to more traditional radical surgery. It offers better sexual, functional, and psychological results and evidence suggests it achieves this without sacrificing oncological outcomes. We examined the evolving nature of such surgeries, addressing controversies such as safe margins and survival outcomes and discussing more conventional techniques, including laser. At our UK center, we treat a high volume of penile cancer and here, based on such experience, we describe our glans resurfacing, glansectomy, and partial penectomy techniques; their application by disease stage; and the limitations of such surgeries...

Primary penile melanomas are rare tumors that represent less than 0.1% of all melanomas. We report a case of a 60-year-old Japanese male with a mucosal penile melanoma and describe an increased CD8(+) T cell infiltration in brain after dacarbazine (DTIC) administration. After partial penectomy and left inguinal lymphadenectomy, he developed multiple lung, bone, spleen, brain and skin metastases. He was treated with interferon-β, DTIC and nivolumab. However, the metastases were not reduced in size. Immunohistochemistry showed an increase of CD8(+) T cell infiltration and programmed death-ligand 1 (PD-L1) expression after the administration of DTIC, but the expression of programmed cell death protein 1 (PD-1) was negative...

Penile cancer is rare cancer. While inguinal and pelvic nodal metastasis is common, distant metastasis is rare. We here present the interesting case of a 59-year-old male patient with penile carcinoma, previously treated with penectomy and inguinal lymphadenectomy 10 years earlier. He presented with bone pains and given history of malignancy he was referred for an (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT). PET/CT demonstrated multiple (18)F-FDG avid bone and lung metastases...
