ABSTRACT
INTRODUCTION: Surveillance is the standard management in low-risk cN0 penile squamous cell carcinoma (peSCC) patients. However, no previous analysis focused on early and long-term outcomes of these patients. We report on main oncological outcomes of a large series of low-risk cN0 peSCC patients. PATIENTS AND METHODS: Between 1980 and 2017 included, 93 evaluable consecutive low-risk (ie, pT1a G1 cN0M0) peSCC patients underwent primary tumor surgery and either observation (74) or dynamic sentinel node biopsy (DSNB) (19) following a clinical diagnosis of T1 in 66 (71%), T2 in 15 (16.1%) and Tx in 12 (12.9%) patients, respectively. The statistical significance of differences in medians and proportions was tested with the Kruskal-Wallis and chi-square tests. Kaplan-Meier plots illustrated 5-year inguinal relapse (IR)-free survival rates. RESULTS: Median age was 60 years (IQR: 50-69 years). Median follow-up was 92 months (IQR 54-133 months). Surveillance was more frequently adopted in clinical (c)T1 than in cT2 tumors (79.7% vs. 36.8%). None of 19 patients who had DSNB had nodal metastasis. Overall, 7 (7.5%) out of 93 pT1aG1cN0 peSCC patients had IR after a median interval of 9 months. Of note, 1 patient only relapsed after 12 months of surveillance. After stratification according to IR, relapses occurred more frequently in younger patients (59 vs. 64 years, P < .001). The 5-year IR-free survival rates for the entire cohort was 92% (95% Confidence interval [CI] 87-98%). CONCLUSIONS: Observation is a safe and effective management for low-risk peSCC patients. Younger patients may be offered a mini-invasive staging as an alternative.

68-years-old man with end-stage-renal-disease (ESRD) and obesity presented with painful penile lesion: necrotic glans, extended till the penile base with the exposition of corpora cavernosa. Laboratory testing were normal and was afebrile so subsequently discharged with antibiotic therapy and medications. Clinical evaluation was suggestive for penile calciphylaxis, confirmed by seeing arterial calcifications at CT. Patient died one month later. Penile calciphylaxis is a rare life-threatening condition characterized by vascular calcification and fibrosis of medium and small arteries which causes an obstructive vasculopathy and tissue necrosis. Normalization of metabolic parameters, antibiotics, topical enzymatic debridement agents are recommended, considering the poor outcome.
