Circumferential Acquired Macropenis: Definition, Literature Review and Proposal of Geometrically-Based Reduction Corporoplasty

Abstract

Introduction: Over the years, scattered cases of acquired penile girth increase have been published with different terms, the common clinical feature being a mechanically hampered penetration.

Aim: To search for all published cases of acquired penile girth increase, and to propose a geometrically-based reduction corporoplasty.

Methods: A case of acquired penile bilateral albuginea herniation prompted us to a PubMed, EMBASE and Google Scholar literature review from 1970 to 2021, in search for similar conditions.

Main outcome measure: We identified 7 cases of acquired penile girth increase; the geometric approach used to surgically correct bilateral corporal herniation proved successful in our case.

Results: In 5 of the 7 cases of acquired penile girth increase, priapistic episodes were deemed the causal factor; in the remaining 2 and in ours, a clear etiology could not be identified.

Conclusion: "Circumferential acquired macropenis" describes the unusual syndrome of acquired penile girth increase, that encompasses 2 distinct etiologies: post-priapistic cases, characterized by penile girth increase both in flaccidity and erection, and idiopathic cases, characterized by girth increase in erection only, and at surgery by a thinned albuginea in the affected area.
