Hirsuties coronae glandis (also known as "hirsutoid papillomas"〔 and "pearly penile papules") are small protuberances that may form on the ridge of the glans of the human penis. They are a harmless anatomical variation. Though sometimes confused with HPV infection, the papules are not a sexually transmitted infection and are not contagious. The papules appear as one or several rows of small, pearly or flesh-colored, smooth, dome-topped bumps situated circumferentially around the corona or sulcus of the glans. They may range in size from less than 1 mm to 3 mm.〔 As of 1999, different studies have produced estimates of incidence ranging from 8 to 48 percent of all men. Studies suggest that it occurs more often on younger men and those who have not been circumcised. They are found in 33.3% of uncircumcised males, and 7.1% of circumcised males.〔 Hirsuties coronae glandis are sometimes described as vestigial remnants of penile spines, sensitive features found in the same location in other primates. In species which retain the full expression of penile spines, the spines contribute to sexual pleasure and quicker orgasms.〔(【引用サイトリンク】title=The real "junk" DNA )〕 A similar expression, vestibular papillomatosis of the vulva or "hirsuties papillaris vulvae", occurs in females and similarly can be misinterpreted as an outbreak of the HPV infection. Like hirsuties papillaris genitalis, it is a normal variation on human anatomy.〔(Colposcopy of the Vulva, Perineum and Anal Canal ).gyncph.dk〕 == Medical removal == While hirsuties papillaris genitalis pose no risk to a male's health, some men or their sexual partners may consider them aesthetically displeasing. There are several medical ways to remove them. Like any elective medical procedure, there is always some risk of unexpected consequences, so doctors advise against their removal unless they are causing a patient serious problems.〔Richard Pattman, Michael Snow, Pauline Handy, Babiker Elawad ''Oxford handbook of genitourinary medicine, HIV, and AIDS'', Volume 13〕 One of the available treatments is performed by a dermatologist, using a CO2 laser to vaporise the papules. This normally takes only a few minutes to perform.〔William Groff, (July 10, 2009) (CO2 Laser Treats Pearly Penile Papules ) American Health & beauty Magazine〕 It is simple and does not normally require a hospital stay; discomfort should be minimal and the expected recovery time is 1 to two weeks. Another procedure involves electrosurgery performed with a hyfrecator and should take less than an hour to perform.〔(【引用サイトリンク】title=Pearly Penile Papules Removal )〕 Both procedures should be out-patient procedures if no complications arise. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「hirsuties coronae glandis」の詳細全文を読む スポンサード リンク
