A 83-year-old man presented to the urology department with a painful swelling of the glans penis. The patient was admitted from the emergency department for pneumonia and urinary tract infection two days before, and a urethral catheter was placed. Physical examination showed preputial edema and a swollen glans penis associated with an ischemia-related hemorrhagic mucosal suffusion (Fig. 1). A d...

Objective: we report here results obtained concerning analyses of the putative penis Napoléon. Methods: SEM-EDX and mtDNA on samples this are realized. Results : studies show that relatively rich in calcium phosphate, consequently “penis” is more likely a piece tendon; mt-DNA analyses, realized two samples, showed presence 16184T mutation only, confirming tendon well

Introduction. Concealed-buried penis is an acquired condition associated with obesity, challenging to both manage and repair. Urethral stricture is a more common disorder with multiple etiologies. Lichen sclerosus is a significant known cause of urethral stricture, implicated in up to 30%. We hypothesize that patients with buried penis have a higher rate of urethral stricture and lichen scleros...

Aims: To explore the combination of environmental and physical factors associated with the development of body dysmorphic disorder (BDD) related to penis size and the differences between men who are anxious about their penis size (but do not meet criteria for BDD), and men who do not report concerns about penis size. Method: Men with BDD (n = 26) were compared to those with small penis anxiety ...
