Application of dermoscopy image analysis technique in diagnosing urethral condylomata acuminata

Abstract

BackgroundIn this study, cases with suspected urethral condylomata acuminata were examined by dermoscopy, in order to explore an effective method for clinical.ObjectiveTo study the application of dermoscopy image analysis technique in clinical diagnosis of urethral condylomata acuminata.MethodsA 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.ResultsAmong the 220 suspected urethral condylomata acuminata, there was a higher positive rate by dermoscopy examination than visual observation.Study limitationsDermoscopy examination technique is still restricted by its inapplicability in deep urethral orifice and skin wrinkles, and concordance between different clinicians may also vary.ConclusionDermoscopy image analysis technique features a high sensitivity, quick and accurate diagnosis and is non-invasive, and we recommend its use.

Vascular dermoscopic features of intrameatal warts

“…However, due to the presence of thick stratum corneum on the wart surface, vessels were difficult to assess. Zhang et al . evaluated 136 cases with clinically suspected urethral warts, with dermatoscopy and dermatopathology.…”

“…10 However, due to the presence of thick stratum corneum on the wart surface, vessels were difficult to assess. Zhang et al 11 evaluated 136 cases with clinically suspected urethral warts, with dermatoscopy and dermatopathology. In their study, they found that the most frequent vascular features of urethral warts were punctate and polymorphic blood vessels.…”

Dermoscopy in China

“…[7] CA has characteristic vascular features, mainly including dotted, annular, dendritic, and hairpin vessels. [7,8] However domestic dermatologists also express dermoscopic features in regards to the lesion's appearance, such as a papillary pattern or a flat pattern. [8,9] Compared to the sensitivity of naked-eye examination (87.7%), dermoscopy improves the sensitivity of diagnosis CA (to 97.4%).…”

[9] Dermoscopy is a non-invasive, convenient, and efficient diagnostic technique for CA, and it can identify lesions that are invisible to the naked eye.…”

Dermoscopy of focal epithelial hyperplasia

“…To the best of our knowledge, the dermoscopy of FEH has not been described before, but the patterns seen seem to be similar to those described in the case of mucosal warts/condyloma, which are also characterized by prominent polymorphic vascular patterns. [ 4 ] The lobules and septation could possibly represent the acanthosis and parakeratosis, and the multiple vessels and vascular distension visible on histopathology are reflected in the vascular patterns seen on dermoscopy.…”
