Abstract

Genital warts are the most common benign hyperplastic lesions caused by HPV infection. Diagnosis workup of genital warts is based on history, physical examination, acetowhite test, dermoscopy, histopathology and polymerase chain reaction (PCR). Dermoscopy is a non-invasive tool used to enhance the diagnostic accuracy of genital warts. This case report aims to understand the diagnostic role of dermoscopy in pigmented genital warts. A 24 years old female with widespread verrucous, confluent, pigmented papules in the inguinal regions bilaterally and labia majora since 4 months ago. Acetowhite test was negative. Dermoscopic examination revealed a mosaic pattern with brownish globular area, knob-like, dan finger-like pattern, and glomerular vessels. Histopatological examination showed hyperkeratosis, acanthosis, papillomatosis, and koilocytes, with increased number of melanocytes in the basal layer. The dermoscopic features of genital warts are varies according to clinical manifestations and shows correlation with histopathologic features. Specific dermoscopic features of genital warts are mosaic patterns, finger-like patterns, knob-like patterns, with/without dots or globules pigmented area, with dotted, glomerular and hairpin vessels. The mosaic pattern correlated with hyperkeratosis, acanthosis and capillary dilatation in the papillary dermis. The finger-like pattern correlated with papillomatosis, hyperkeratosis, acanthosis, dilatation and elongation of vessels. The identification of specific dermoscopic features in correlation with clinical manifestation and histopathological can be used to establish diagnosis of pigmented genital warts.
