Morbus Bowen in the Os Pubis Region: Dermatosurgery as Treatment Choice

Morbus Bowen also known as squamous cell carcinoma in situ, is a disease which is characterised by abnormal squamous cells within the epidermis whilst the basement membrane stays intact. Higher prevalence is shown in older age groups and individuals with higher sun exposure. If left untreated the disease could progress into invasive squamous cell carcinoma, which could lead to local tissue destruction and perineural invasion. We report a case of a 53-year-old male presenting with a reddish plaque in the right inguinal area. Routine investigation determined the patient to have Bowen’s disease. Dermatosurgical management was deemed the best option with the benefits greatly outweighing the risks in comparison to other therapies. Surgical intervention proved to be successful showing no complications. This case highlights the efficacy of dermatosurgical management for perigenital Bowen’s disease and underscores the importance of early diagnosis and individualized treatment planning.
