    TLDR HPV-150 and HPV-151 are rare skin viruses linked to warts and some skin cancers.
    The study characterized two novel HPV genotypes, HPV-150 and HPV-151, isolated from hair follicles of immuno-competent individuals. These genotypes were fully sequenced, revealing genomes of 7,436-bp and 7,386-bp, respectively, and were placed within the Betapapillomavirus genus. Both genotypes were found to have a cutaneous tropism and were detected in sporadic cases of common warts and skin cancers, such as SCC and BCC, with low viral loads. HPV-150 was capable of establishing persistent infections in hair follicles. The study also identified a partial L1 sequence of a related novel HPV genotype in a skin cancer sample from an immuno-compromised patient. Quantitative PCR assays were developed to assess the presence of these genotypes, showing that they were relatively rare among the 540 samples tested.

      Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
