A new option for the treatment of condyloma acuminatum in the male urethra: Multimodal ultrasound image-guided scraping and photodynamic therapy (USP).

OBJECTIVES: Condyloma acuminatum (CA) is a sexually transmitted disease with a high recurrence rate due to the rapid replication of human papillomavirus (HPV) and its subtle immune escape mechanism, which makes the diagnosis and treatment of CA in the male urethra particularly difficult. This study aims to evaluate the efficacy of comprehensive treatments for male urethral CA after accurate localization of warts under ultrasound guidance. METHODS: The study included 15 men with intraurethral CA. Before treatment, the urethra was examined by ultrasonography and HPV-PCR. After examination of the invisible urethral warts, wart curettage (penetrating operation with a special stainless steel medical curettage tool) combined with ALA-PDT was used for treatment. The ultrasound and HPV load were reviewed 1 week after treatment, and again at 1, 3, and 6 months after treatment. RESULTS: All patients achieved satisfactory results 1 week after the last treatment. The viral load of human papilloma was significantly reduced or turned negative, ultrasound imaging exploration showed no neoplasm in the urethra, and no obvious intraoperative or postoperative complications were observed. The side effects in patients included a mild burning or tingling sensation confined to the treated area. After a 6 month follow-up period, only 2 patient relapsed. CONCLUSION: The combined diagnosis and treatment of CA in the male urethra under the guidance of multi-mode ultrasound imaging is an effective, economical, safe, and well-tolerated treatment method.

Dermoscopic findings of genital keratotic lesions: Bowenoid papulosis, seborrheic keratosis, and condyloma acuminatum.

Dermatologists often encounter keratotic or warty lesions in the genital area. Establishing a clear diagnosis may seem challenging, particularly when the differential diagnosis includes bowenoid papulosis, seborrheic keratosis, and condyloma acuminatum. This study aimed to compare the dermoscopic features of bowenoid papulosis (BP), seborrheic keratosis, and condyloma acuminatum in the genital area. All lesions histopathologically confirmed underwent clinical assessment and dermoscopic observation. Dermoscopically, glomerular vessels were predominant in bowenoid papulosis, whereas seborrheic keratosis was the least vascular-patterned disease. Most cases of bowenoid papulosis presented mucosal pigmentation and classified as "flat". Seborrheic keratosis had a pigmented, cerebriform appearance. Condyloma acuminatum was characterised by a finger-like appearance, highly vascular-patterned features surrounded by whitish halos. Dermoscopic findings can be useful for differentiating the entity of genital keratotic lesions ahead of an invasive method. When dermoscopic features favor BP, different from genital warts, it should be removed completely but conservatively.

Challenge of reflectance confocal microscopy in the diagnosis of genital warts. / åå°„å¼å ±èšç„¦æ˜¾å¾®é•œåœ¨ç”Ÿæ®–å™¨ç–£è¯Šæ–­ä¸­é¢ä¸´çš„æŒ‘æˆ˜.

OBJECTIVES: Reflection confocal microscopy (RCM) is commonly used to assist in the diagnosis of skin diseases. RCM has been found to be useful in the diagnosis of genital warts. The characteristics of genital warts under RCM are not specific. This study aimed to face the challenge of diagnosing genital warts with RCM. METHODS: We retrospectively studied 161 patients with clinical diagnosis of genital warts who underwent RCM examination. Histopathological examination was performed for 75 of these patients. The results of histological diagnosis and RCM diagnosis were compared and analyzed. RESULTS: According to the RCM images, 102 of the 161 (63.35%) patients were diagnosed as genital warts. By comparison with histological results, the misdiagnosis rate of the 75 biopsy cases was 35.48% and the missed diagnosis rate was 20.45%.The diseases of misdiagnosis and missed diagnosis mainly included bowenoid papulosis, pseudocondylona of vulvae, squamous cell carcinoma in situ, molluscum contagiosum, and lichen planus. We further found that the RCM characteristics of genital warts conformed by histology were koilocytes, which mainly appeared in the granular layer or the spinous layer, larger than normal skin keratinocytes, and the cytoplasm with low refractive index. CONCLUSIONS: Due to the commonality of the microscopic characteristics of genital warts and related diseases, some cases are easy to be misdiagnosed or missed diagnosed. Diagnostic koilocytes could be an important basis for the diagnosis of genital warts.

Application of dermoscopy image analysis technique in diagnosing urethral condylomata acuminata.

BACKGROUND: In this study, cases with suspected urethral condylomata acuminata were examined by dermoscopy, in order to explore an effective method for clinical. OBJECTIVE: To study the application of dermoscopy image analysis technique in clinical diagnosis of urethral condylomata acuminata. METHODS: A total of 220 suspected urethral condylomata acuminata were clinically diagnosed first with the naked eyes, and then by using dermoscopy image analysis technique. Afterwards, a comparative analysis was made for the two diagnostic methods. RESULTS: Among the 220 suspected urethral condylomata acuminata, there was a higher positive rate by dermoscopy examination than visual observation. STUDY LIMITATIONS: Dermoscopy examination technique is still restricted by its inapplicability in deep urethral orifice and skin wrinkles, and concordance between different clinicians may also vary. CONCLUSION: Dermoscopy image analysis technique features a high sensitivity, quick and accurate diagnosis and is non-invasive, and we recommend its use.

Time-lapse imaging points towards a non-toxic, mainly immune-driven mode of action of ingenol mebutate in the treatment of anogenital warts.

Recently, it has been reported that ingenol mebutate (IM) is an effective treatment option for anogenital warts (AGW), inducing fast wart necrosis within 24 hours in vivo. With regard to its mode of action, IM is thought to act both as an inducer of direct cytotoxic effects and immunologic mechanisms. To distinguish whether the wart necrosis is mainly caused by cytotoxic effects, or whether immune mechanisms are leading, we used time-lapse imaging to analyse IM-treated warts ex vivo over 24 hours. Ex vivo IM-treated warts, which have been detached from the immune system, did not show destructive necrosis, pointing towards a primarily immune-driven mode of action of IM in the treatment of AGW.

Vestibular papillomatosis: An important differential diagnosis of vulvar papillomas.

Most authors believe that vestibular papillomatosis (VP) is an anatomical variant of the vestibular mucosa. But VP is sometimes misdiagnosed as genital warts and this can lead to aggressive investigations, therapy, and anxiety in patients. We present a patient with VP. Dermoscopy and reflectance confocal microscopy (RCM) were performed to differentiate VP from other papilomatous diseases of the vulva.

Condyloma acuminata induces focal intense FDG uptake mimicking vaginal stump recurrence from uterine cervical cancer: a case report.

The 2-deoxy-2-[18F] fluoro-D-glucose position emission tomography/computed tomography (FDG PET/CT) findings of condyloma acuminata in a patient with FIGO Stage IB1 cervical cancer who had previously been treated with radical hysterectomy, pelvic chemoradiotherapy, and consolidation chemotherapy is described in this article. This case highlights the importance of considering condyloma acuminata during the differential diagnosis of abnormal vaginal FDG uptake in patients who have been treated for gynecological cancer.

The 18F-FDG PET/CT finding of a condyloma acuminata mimicking primary anorectal carcinoma in an HIV-infected patient.

This case report describes a condyloma acuminata with intense FDG uptake mimicking primary anorectal carcinoma in an HIV-infected patient.A 44-year-old HIV-positive homosexual man with a history of lymphoma underwent an 18F-FDG PET/CT for restaging. A focal intense hypermetabolic lesion around the anorectal area was found by the PET/CT and it was suggested as a tumorous lesion. However, the lesion was not detected on the contrast-enhanced abdominal CT. Via a sigmoidoscopy, cauliflower-like masses were visualized in the intra-anal area. The tumor was surgically excised and proven to be condyloma acuminata by permanent pathology.

Condyloma mistaken for stool contamination in a human immunodeficiency virus patient by gallium-67 scintigraphy.

We demonstrated a unique image finding related to condyloma in a patient infected with human immunodeficiency virus. It is worth noting that a thorough literature search of the available databases to date failed to retrieve any case reports of condyloma with representative gallium-67 scintigraphic images.

[Ultrasonographic assessment of urethral condyloma acuminatum in men].

OBJECTIVE: To evaluate the value of ultrasonography in diagnosing urethral condyloma acuminatum (CA) in men. METHODS: Twenty-two male patients, aged 36 +/- 19, diagnosed as with urethral CA based on history and clinical symptoms underwent ultrasonography and urethroscopy. The patients were asked to micturate to distend the urethra. The posterior urethra was detected by transrectum approach. Transperineal scans were performed to image the bulbar urethra, scrotal urethra and penile urethra. The sonographically positive results were compared with the pathological results. RESULTS: Eighty-three vegetations were found in the anterior urethra of seventeen patients, and eighty-one vegetations were diagnosed as CA by pathology, of which 1.2% were polyp shape, 38.3% papillary shape, and 60.5% cauliflower mass. Sonourethrography was an accurate predictor of papillary shape and cauliflower mass; however, it was difficult to differentiate between polyp shape vegetation and crystal. CONCLUSION: Sonourethrography is a sensitive and accurate tool not only for primary diagnosis of but also for follow-up of urethral CA in men.

[EUS results of malignant rectal giant condyloma acuminatum (Buschke-Loewenstein tumor)]. / Aspect echoendoscopique d'un condylome acuminé géant rectal malin (tumeur de Buschke-Loewenstein).

Giant condyloma acuminatum is a large, exophytic, cauliflower-like lesion that usually affects the anogenital region. Localisation in the rectum is uncommon and has a high rate of malignant transformation but does not lead to develop distant metastases. For the time, we report the endosonographic appearance of a malignant intrarectal giant condyloma acuminatum.
