Hi,
I think it appears to me as External Genital Wart’s. This is common and an estimated 24 million Americans are infected with HPV.
EGWs are visible warts that occur in the genital area (e.g., penis, scrotum, perineum, vulva, perianal area, pubic area, upper thighs, and crural folds). They appear as discrete lesions or may coalesce into confluent plaques. The clinical diagnosis of EGWs in the immunocompetent patient by physical examination is reliable on the basis of a good correlation between physical findings and histological studies. Clinical inspection, without the aid of instrumentation (i.e., colposcopy, anoscopy, and urethroscopy), is sufficient to diagnose most EGWs. EGWs are frequently multifocal, with one or more lesions on one anatomic site (e.g., vulva), or multicentric, with lesions on disparate anatomic sites (e.g., perineum and cervix). Thus, it is important to examine the entire lower genital tract for the presence of multicentric visible warts before treatment.
I think you should consult a dermatologist to evaluate this condition and decide regarding further management.
It can also be due to some fungal infection which is been picked up.
Hope this helps.
Bye.
