Hello, * Apparent reason for the itchy flaky skin with bad odor is obvious fungal infection with or without associated bacterial contamination. * Many of the times, it is noticed that root cause is the inability to retract the foreskin completely as in case of phimosis, smegma collects underneath the foreskin and repeated infection is the result. Sexually transmitted diseases ( if active ) must be considered in the second category. In a nut shell, get an examination of the doc, necessary blood, swab, and culture report for final cure accordingly. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Bhagyesh V. Patel, General Surgeon
