Histology and immunohistochemical evaluation of phimotic prepuce: The role of steroid therapy.

Phimosis is one of the most frequent andrological diseases in paediatric age. Steroids are useful to treat phimosis. Through a retrospective study of histological and immunohistochemical analysis, we evaluated the effectiveness of topical steroid treatment in patients undergoing circumcision. Cases of patients treated for phimosis were selected during the two-year study period. All patients underwent circumcision and were divided into four groups: groups A (religiously circumcised patients), B (phimotic patients not undergoing steroid treatment), C (phimotic patients who do not respond to cortisone treatment) and D (hypospadic patients undergoing urethroplasty). An histological evaluation of the degree of fibrosis and an immunohistochemical evaluation of collagen IV and tenascin were carried out. Study results demonstrate that the grade of fibrosis is age-related. On histological and immunohistochemical evaluation, fibrosis was found to be lower in patients receiving steroids; higher degrees of fibrosis were found in older patients (p < .05). Different degrees of fibrosis have also been found in hypospadic patients. We can conclude that study results correlated with the clinical history of the patients. The success rate of medical therapy seems to be age-related.
