“…The brown areas typically lie on the periphery of the lesion and appear larger than the pBCC’s characteristic maple-leaf areas ( Yang et al, 2017 ). Similarly, nonspecific dermoscopic findings suggesting both melanocytic (e.g., pigment network, streaks, variegated colors, amorphous patterns) and nonmelanocytic (e.g., defined borders, comedo-like openings) neoplasms have been reported in the literature in pBD in SoC ( Gutierrez-Mendoza et al, 2010 , Cavalleiro de Macedo Mota et al, 2014 , Vivan et al, 2017 ). The anatomic distribution in SoC and likely decreased index of suspicion have the potential to delay diagnosis; therefore, dermoscopic clues should be utilized for additional information.…”

Background Dermoscopy is undoubtedly a useful tool to improve diagnostic accuracy and minimize the number of unnecessary biopsies. However, much of the literature on dermoscopy focuses on findings in lighter-skin phototypes, leaving potential gaps of knowledge regarding its use in skin of color (SoC). As the clinical applications of dermoscopy continue to increase, understanding dermoscopic patterns in SoC is imperative. Objective This review discusses the literature on dermoscopic findings of neoplasms in SoC, highlighting unique and characteristic dermoscopic features. Methods A literature review was performed using the PubMed database. Case reports, case series, case-control studies, and systematic reviews were included. Results A total of 8326 studies were identified based on the selected search terms, and 41 were included in this review based on relevance. Conclusion There are specific dermoscopic characteristics in SoC for benign nevi, acral lentiginous melanoma, ethnic melanonychia, and dermatofibroma; however, there is a lack of published data about specific features of cutaneous melanoma, subungual melanoma, pigmented basal cell carcinoma, and pigmented squamous cell carcinoma in SoC. Because pigmented basal cell carcinoma, pigmented squamous cell carcinoma, ethnic melanonychia, and acral lentiginous melanoma are diagnosed at later stages in this population, it is important to understand their dermoscopic features. Further descriptive studies are needed to better characterize unique dermoscopic features in neoplasms in SoC.

The penile localization of pigmented Bowen’s disease has been rarely reported and has been mostly related to human papillomavirus infection. Early diagnosis and treatment are important to prevent progression to invasive squamous cell carcinoma. However, diagnosis can be challenging because it may be difficult to distinguish from melanoma, even using dermoscopy. Reflectance confocal microscopy may be useful in suggesting the bedside diagnosis before the histopathological confirmation. A case of penile pigmented Bowen’s disease is described along with its dermoscopy and reflectance confocal microscopy findings and their correlation with histopathology.

“…Pigmented Bowen's disease (pBD) is a subtype of Bowen's disease (BD) that has increasing melanin deposition in the lesional epithelium and/or the papillary dermis. It manifests as a slow‐growing, well‐demarcated, hyperpigmented plaque, and should be included in the differential diagnoses of pigmented skin lesions such as pigmented actinic keratosis, solar lentigo, seborrheic keratosis, lichen planus‐like keratosis, different types of melanocytic nevi, melanoma and pigmented basal cell carcinoma . Some studies have focused on the dermoscopic features of pBD, but nothing has been reported on clonal‐type pBD.…”

Pigmented Bowen's disease (pBD) is a subtype of Bowen's disease, which presents clinically as a well‐circumscribed, hyperpigmented plaque. Its clinical manifestations are not fully characterized, and differential diagnoses include various pigmented skin lesions. Dermoscopy could be useful for the diagnosis, although nothing has been reported on the dermoscopic features of clonal‐type pBD. We herein report a first case of clonal‐type pBD on the sole and its dermoscopic features. Dermoscopy showed brown to blue‐gray dots/globules and focally anastomosing lines on the non‐weight‐bearing area, while the weight‐bearing area had a brown to blue‐gray fibrillar‐like pattern. To investigate the relationship between dermoscopy and histopathology, we focused on the melanin distribution in the horny layer of the epidermis, and used vertical dermoscopy observation. We investigated the relationship between dermoscopy and pathology by melanin depth estimation using a color lightness value.
