Abstract

Extensively large redundant part of the prepuce extended beyond the glans penis, sometimes representing more than three-quarters of the length of the penis, considered as a normal variation, and the term“akroposthion” given to this redundant part but a whole prepuce that has been deliberately lengthened is defined as a congenitally abnormal one, and described as a secondary megaprepuce.

Definition

Extensively large redundant part of the prepuce extended beyond the glans penis, sometimes representing more than three-quarters of the length of the penis, considered as a normal variation, and the term“akroposthion” given to this redundant part (Fig. 6.1), but a whole prepuce that has been deliberately lengthened is defined as a congenitally abnormal one, and described as a secondary megaprepuce [1] (Fig. 6.2). Another rare condition has only recently received recognition as an entity in its own right is the congenital megaprepuce (CM), which characterized by extensive redundancy of the inner preputial skin over a penile shaft and glans of normal shape and size (Fig. 6.3), or it could be presented as an enormously capacious preputial sac, engulfing the whole penile shaft and upper scrotum, with urine accumulation in the preputial sac (prompting the term “preputial bladder”) (Fig. 6.4).

6.1 History


The longer prepuce often serves as the object of erotic interest and as a signifier of the sexually attractive male along the history, the Greeks valued the longer over the shorter prepuce in relation to the length of the entire penis, and the smaller over the larger penis as a whole. The term congenital megaprepuce (CM) was first used in a case report in 1994 by O’Brien et al. [2], and since then increasing numbers of patients with CM have been reported.


6.2 Incidence


This rare condition has only recently received recognition as an entity in its own right, and it is possible that it represents a genuinely new pathology, where a part of the foreskin extends beyond the glans, and it is possible that many cases may exist among children, but escape reporting, as there is no study till now reported the exact incidence of megaprepuce among normal children.
