Giant condyloma acuminatum (GCA), or Buschke-Löwenstein tumor (BLT), represents an infrequent sexually transmitted disease (STD), caused by human papillomavirus (HPV), especially genotype 6 or 11. There are numerous risk factors for HPV, such as multiple sexual partners, homosexuality, prostitution, chronic genital infections, as well as the lack of proper hygiene. HPV infection is a field infection, where large areas of cells at a tissue surface are affected by the HPV virus; therefore, once the GCA is excised, treatment of the whole affected genital area needs to be undertaken. The treatment is classified into topical therapy (podophyllin, 5-FU, radiotherapy, topical photodynamic therapy), excisional therapy (CO laser, cryotherapy, electrotherapy, surgery) and immunotherapy (imiquimod). However, the 'gold standard' therapy is represented by wide surgical excision without grafting, since it is considered that healing is an improved approach, because there is no risk of recurrences on fibrotic tissue. A total of 7 cases of the BLT with comorbidities and particularities are presented and it is recommended that it be taken into consideration that the incidence of the disease is increasing, emphasizing the importance of an early diagnosis, as well as an adequate treatment.

β-apopicropodophyllin (APP), a derivative of podophyllotoxin (PPT), has been identified as a potential anti-cancer drug. This study tested whether APP acts as an anti-cancer drug and can sensitize colorectal cancer (CRC) cells to radiation treatment. APP exerted an anti-cancer effect against the CRC cell lines HCT116, DLD-1, SW480, and COLO320DM, with IC50 values of 7.88 nM, 8.22 nM, 9.84 nM, and 7.757 nM, respectively, for the induction of DNA damage. Clonogenic and cell counting assays indicated that the combined treatment of APP and γ-ionizing radiation (IR) showed greater retardation of cell growth than either treatment alone, suggesting that APP sensitized CRC cells to IR. Annexin V-propidium iodide (PI) assays and immunoblot analysis showed that the combined treatment of APP and IR increased apoptosis in CRC cells compared with either APP or IR alone. Results obtained from the xenograft experiments also indicated that the combination of APP and IR enhanced apoptosis in the in vivo animal model. Apoptosis induction by the combined treatment of APP and IR resulted from reactive oxygen species (ROS). Inhibition of ROS by N-acetylcysteine (NAC) restored cell viability and decreased the induction of apoptosis by APP and IR in CRC cells. Taken together, these results indicate that a combined treatment of APP and IR might promote apoptosis by inducing ROS in CRC cells.

Bowen's disease (BD) is an intraepidermal squamous cell carcinoma (SCC) with the capacity to become invasive SCC giving rise to distant metastasis. In rare cases it can be associated with human papillomavirus (HPV) infection, specifically with HPV types 16, 18, 31, 32, and 34. Here we report a case of an immunocompetent white male, age 37, with an erythematous, irregularly-shaped patch in his suprapubic region, appearing 1 year after treatment for condylomata acuminata with cryotherapy and podophyllin in the same area. At the time of clinically active disease, a urethral smear was positive for high-risk HPV types. The lesion was considered a scar by several physicians because it emerged in an area of previous postinflammatory hyperpigmentation. The aim of this report is to raise awareness of the emerging causative association between anogenital HPV infection and the development of BD, which was the possible etiological agent in the case of the patient presented here. Hereby we also advocate primary preventive measures in terms of safe sexual habits and HPV vaccination.

BACKGROUND
Buschke-Löwenstein tumor is a giant condyloma acuminata infection that is characterized by degeneration, invasion, and recurrence. It is associated with human papilloma virus infection. It develops around the genital and perineal area, sometimes causing a large budding ulcerated lesion. Although human immunodeficiency virus infection is frequent in Africa, there are few descriptions of Buschke-Löwenstein tumor diagnosis and its management. Screening for other sexually transmitted infections must be systematic among these patients.
CASE PRESENTATION
We report herein the case of a 21-year-old African origin male patient who developed a perineal swelling. Physical examination showed evidence of a huge exophytic tumor made up of budding pinkish vegetations, with serrated crests, a ''butterfly wing'' structure, and a cauliflower-like appearance crowned with centrifugal circinate lesions. Multiple condylomatous lesions of the anal margin were also present. The patient tested positive for human immunodeficiency virus (cluster of differentiation 4 count of 119 cells/mm) and hepatitis B infections. Real-time polymerase chain reaction revealed human papilloma virus-16 and other high-risk human papilloma virus deoxyribonucleic acid. The diagnosis of Buschke-Löwenstein tumor was made on mass biopsy, and the patient underwent multidisciplinary intervention (surgery, podophyllin application, and antiretroviral therapy). Medium-term evolution was, however, fatal due to opportunistic infection.
CONCLUSION
Buschke-Löwenstein tumor is a rare tumor associated with human immunodeficiency virus infection. It is more frequent in male human immunodeficiency virus-positive patients. There is a need to screen for other sexually transmitted infections. In most cases, the treatment is surgical, in association with local therapies. However, recurrences are common.

Molluscum contagiosum (MC) is a benign papular skin infection caused by Molluscum contagiosum virus (MCV). Over the past 30 years, the incidence of MK has continued to increased association with sexually transmitted infections and human immunodeficiency virus (HIV) infection. The incidence of MC in HIV patients is quite high at 5-8%. Until now there is no standard therapy used for the treatment of MC in patients with HIV. In HIV patients, anti retro viral therapy (ARV) is the main therapy with several other additional therapies such as cantaridin, chemical peeling agents such as glycolic acid (20-70%) and trichloroacetic acid (20-100%), cryosurgery, electrosurgery, incision, lactic acid, laser surgery, podophyllin, retinoic acid, and urea. There have been no studies regarding the administration of topical 20% glycolic acid in MC patients. We report a case of MC in an HIV patient who was treated with 20% topical glycolic acid after failing treatment with topical tretinoin. The diagnosis was made clinically, cytologically, and histopathologically, a white mass was found on compression of the lesion and Henderson-Paterson bodies. The lesions on the face, arms, and legs were given glycolic acid lotion 20% which was applied once a day at night. The lesions started to show responses to the treatment at week 6th as some of the MC papules became hyperpigmented macules. The side effects of therapy that appeared were itching and hyperpigmentation. Topical 20% glycolic acid can be used for MC therapy with minimal side effects, easy to apply and safe.

Bowen's disease (BD) is a premalignant condition. Its exact etiology is unknown but chronic arsenic and sun exposure, and human papillomavirus infection is known predisposing factors. Pigmented lesions of BD represent 1.7%-5.5% of all BD cases. BD in the nail unit is challenging due to its varied clinical presentations such as fissure, ulceration, warty lesion, paronychia, onychocryptosis, and nail dystrophy. We present the case of a 43-year-old married, immunocompromised male (HIV), with a CD 4 count of 478, on tenofovir, atazanavir boosted with ritonavir regimen, known diabetic presented with multiple asymptomatic discrete, rounded, hyperpigmented verrucous papules on both surfaces of shaft of penis and scrotum and a single, 4 cm × 3 cm, irregular, smooth surfaced, hyperpigmented plaque, on the base of the penis extending to the upper part of the scrotum of 1-year duration with history of multiple unprotected sexual exposures with unknown female partners. Regional lymphadenopathy and systemic complaints were absent. Biopsy from hyperpigmented verrucous papule and hyperpigmented plaque was consistent with verruca vulgaris and pigmented Bowen's disease, respectively. The patient was lost to follow-up. Ten months later, he presented with longitudinal melanonychia with a subungual hyperpigmented mass protruding beyond the distal nail margin near the lateral nail fold of the right middle finger nail with an absent Hutchinson's sign. Longitudinal excisional biopsy of nail lesion was consistent with BD. He was started on 5-fluorouracil 5% for BD of genitals and podophyllin application for verruca vulgaris with remarkable improvement in both the lesions and there is no recurrence of nail lesion after 9 months of excision.

HPV clinical manifestations have their characteristics modified by the use of combined antiretroviral therapy (cART), although its incidence is unaffected by cART. We report an unusual presentation of oral HPV infection and discuss an effective treatment for disseminated HPV lesions. A 52-year-old male of Asian-origin, HIV-seropositive, presented with extensive nodular lesions throughout the oral mucosa extending to the oropharyngeal region. Biopsy followed by histopathological examination and HPV genotyping were performed. The treatment was initiated with topical application of podophyllin and trichloroacetic acid. HPV lesions in oral mucosa are generally easy to handle. Extensive lesions can make it difficult to choose an effective treatment that meets the patient's particularities and medication availability.

Cantharidin-Podophyllin-Salicylic Acid Formulation as a First-Line Treatment for Plantar Warts? A Case Report with Multiple Plantar Warts of Human Papillomavirus Biotype 27 and Previous Failed Treatments.
BACKGROUND Plantar warts are benign skin tumors caused by the human papillomavirus (HPV). There are multiple treatments, but none ensure absolute success. Successful treatment depends on several factors, such as the location, number of lesions, HPV biotype, and the patient's health condition. This report presents a 53-year-old woman who had multiple recalcitrant plantar warts with HPV biotype 27 that were treated using a cantharidin-podophyllin-salicylic acid (CPS) formulation after 2 failed treatments. CASE REPORT A 53-year-old woman was seen on October 25, 2021. She had 6 plantar warts due to HPV biotype 27, which was confirmed by polymerase chain reaction using a sample of hyperkeratosis scales obtained from the wart after debridement. Five cryotherapy sessions were applied, without clinical improvement. Two sessions of nitric-acid-zinc complex were then applied, from which the patient reported severe pain, without clinical improvement. Finally, 3 sessions of CPS formulation were applied, and the HPV remitted in all warts. CONCLUSIONS Conservative treatments, such as cryotherapy, have not been effective in a case of multiple recalcitrant plantar warts. The combined action of the 3 compounds of CPS formulation was key in the resolution of this case. Plantar wart treatment should be easy to apply, effective, fast, and efficient. In cases of recalcitrant or numerous warts, treatment should be more aggressive from the beginning if the patient's lifestyle allows it. It would be interesting to conduct randomized clinical trials to find out which patients could be indicated for the CPS formulation as a first line of treatment.
