CD207 Expression Level is a New Prognostic Marker for Condyloma Acuminatum.

Background: Condyloma cuminata (CA) is a sexually transmitted disease caused by human papillomavirus (HPV) infection, which is prone to recurrence and difficult to cure in the short term. CD207 is a C-type lectin receptor that is specifically expressed on the surface of Langerhans cells (LCs) and is considered as an LC-specific immunohistochemical marker. The main purpose of this study is to explore the correlation between the expression of CD207 in CA skin lesions and the duration of CA disease course and frequency of recurrence, in order to provide new prognostic markers for CA to clinicians. Materials and Methods: A total of 40 male patients with CA and their skin lesions were collected, as well as 40 healthy male penile tissue samples. The skin lesions of CA were clinically and histologically confirmed by acetic acid test. The expression of CD207 in epidermal tissues was detected using immunohistochemistry. The difference in the number of CD207 positive cells between CA skin lesions and healthy skin controls was compared, and the association between the number of CD207 positive cells in CA skin lesions and the duration of disease course and the frequency of recurrence was determined through Spearman correlation analysis. Conclusion: In CA skin lesions, CD207 positive cells were found to have morphological abnormalities and the number of cells was significantly reduced compared to healthy skin, suggesting that there may be antigen presentation dysfunction in CA skin lesions, which may be the reason for the prolonged and unresolved condition of the disease. The fewer CD207 positive cells in CA skin lesions, the longer the disease course and the more frequent the recurrence, therefore, the expression level of CD207 can be used as a new prognostic marker for predicting the outcome of CA.
