Affecting only 6 in 1000 males (0.6%), BXO is a rare disease which can affect males at any age.<ref name="parsad" /> As rare as it may be, BXO is a relatively serious disease. It can cause urethral stricture and retention of urine.<ref name="freeman" /> Malignant tumors have been reported to develop from BXO, albeit very rarely.<ref name="freeman" /><ref name="shankar">Shankar KR, Rickwood AM.

== Diagnose ==
Freeman and Laymon (1941) provide a detailed classic description of the disease:<ref name="freeman" /> BXO is usually distinguished by a ring of hardened tissue with a whitish color at the tip of the [[foreskin]]. The hardening of the tissue prevents [[retraction of the foreskin]].<ref name="shankar" /> Immunophenotyping may be useful in differential diagnosis.<ref>Hinchliffe SA, Ciftci AO, Khine MM, ''et al.'' [http://www.cirp.org/library/treatment/BXO/hinchliffe1/ Composition of the inflammatory infiltrate in pediatric penile lichen sclerosus et atrophicus (balanitis xerotica obliterans): a prospective, comparative immunophenotyping study].

''Acta Derm Venerol'' (Stockholm) 1977;57:275-7.</ref><ref name="rickwood-boys">Rickwood AMK, Hemalatha V, Batcup G, Spitz L.

[http://www.cirp.org/library/treatment/BXO/depasquale1/ The treatment of balanitis xerotica obliterans]. ''BJU Int'' 2000;86(4):459-65.</ref> The presence of BXO must be confirmed in order to consider the choice of treatment modality. If the biopsy rules out BXO as a cause of non-retractile foreskin, then conservative treatment is most likely possible. If, on the other hand, a biopsy confirms the presence of BXO, the choice of treatment modality is more difficult.
== Behandlung ==
In the past, the traditional treatment of BXO has been radical [[circumcision]].<ref name="meuli">Meuli M, Briner J, Hanimann B, Sacher P. [http://www.cirp.org/library/treatment/phimosis/meuli/ Lichen sclerosus et atrophicus causing phimosis in boys: a prospective study with 5-year followup after complete circumcision]. ''J Urol'' 1994:152(3):987-9.</ref> However, many conservative treatment options are now available.
=== Conventional vs. conservative treatment ===
Conventional medical wisdom has stated that BXO is an absolute indication for circumcision,<ref name="meuli" /> however, this treatment modality dates from a time when the prepuce was considered to have no value for the individual. In more recent times, this is no longer the case, as the function and value of the prepuce are now being recognized, and males may wish for treatment that preserves the integrity of their organs; protection of the individual from unnecessarily radical surgery is always a doctor's prerogative. Fortunately, thanks to advances in modern medicine, researchers have reported some success with conservative therapies for BXO that spare the patient from surgery and preserve the prepuce.
==== Non-surgical treatment ====

== Conclusion ==
There still seems to a wide range of opinion on the best treatment modalities for BXO. The cause is still unknown, although Shelley ''et al''. (1999) hypothesize spirochete infection.<ref name="neuhaus" /> More research is needed. Now, however, there is a good possibility of successful treatment without radical circumcision.<ref>Dalton JD. [http://bmj.com/cgi/eletters/321/7264/792#10014 BXO does not require treatment by circumcision]. (letter) ''BMJ'' 2000; rapid response pages.</ref> The trend today seems to be for greater use of medical treatment and less use of radical surgery in the treatment of BXO.
