Introduction: Lichen sclerosus (LS), or balanitis xerotica obliterans, is a chronic, inflammatory disease accompanied by cicatrizing skin conditions resulting in pathologic phimosis. LS can be detected clinically by the whitish appearance of the glans or the foreskin, thickened, nonretractable foreskin, dysuria, and spraying. However, diagnosis is confirmed histopathologically.
Purpose: The aim of this study was to investigate whether LS can be diagnosed on the basis of clinical manifestation and symptoms.
Patients and methods: A retrospective analysis was performed, which included boys referred to our institutions for phimosis evaluation between May 2001 and December 2016. Pediatric urologists clinically diagnosed LS preoperatively. Boys with voiding problems, recurrent balanoposthitis, or who were unresponsive to topical steroid treatment underwent surgical treatment. Patients who underwent religious circumcisions were not included.
Results: Three-hundred twenty boys diagnosed with phimosis were identified, and 71 (22%) boys underwent surgery. Fifty-eight boys underwent complete or partial circumcision, and 13 boys underwent a dorsal slit or preputioplasty. Thirty foreskin samples were sent for histopathologic examination. Histopathologic evaluation showed evidence of LS in 13 of 30 (43%) circumcised boys, chronic inflammation in ten (33%), no abnormality in four (13%), dysplasia in two (7%), and acute inflammation in one (3%). In the 22 boys who were clinically diagnosed with LS, 13 patients had histopathologic evidence of LS (59%). Visually, eleven cases had whitish foreskins and 21 cases had thickened nonretractable foreskins, of which there were seven (64%) (P>0.05) and 12 (57%) (P<0.01) cases, respectively. These cases were histopathologically diagnosed with LS. Both whitish and thickened, nonretractable foreskin was observed in eight patients, of which seven (88%) (P<0.01) were also histologically diagnosed with LS. There was no correlation between histopathologic diagnosis and preoperative symptoms such as dysuria, ballooning, spraying, or penile pain (P>0.2).
Conclusion: It is difficult to reliably distinguish whether a patient has histopathological LS by clinical findings alone.
