Case of pigmented Bowen's disease on the volar aspect of the finger dermoscopically mimicking melanoma in situ

Abstract

Interestingly, a similar phenomenon was observed in this case. Regular hairpin vessels are seen in seborrheic keratosis. 1,5 This melanoma was accompanied by senile lentigo, which can be the precursor of seborrheic keratosis. It may be one of the possible mechanisms by which regular hairpin vessels become conspicuous by melanoma. Recently, black-blue color has been reported to be an important dermoscopic clue to recognize nodular melanoma. 2 However, black-blue color was uncertain probably because this case was hypomelanotic melanoma and such a confusing case still may exist. We should keep in mind that typical dermoscopic features of pigmented basal cell carcinomas can be found in melanomas.

Early aggressive intervention for infantile atopic dermatitis to prevent development of food allergy: a multicenter, investigator-blinded, randomized, parallel group controlled trial (PACI Study)—protocol for a randomized controlled trial

“…Early aggressive treatments are modified from the Hanifin et al study intervention, and details are described in Additional file 1 . On the other hand, participants in conventional treatment group obtain standard treatment based on the Guidelines for the Management of Atopic Dermatitis (2016) [ 20 ] (Step-up reactive method). Standard treatment is based on the Guidelines for the Management of Atopic Dermatitis (2016) [ 20 ], and the details are described in Additional file 1 .…”

A Case of Pigmented Bowen Disease on the Finger Mimicking Melanoma Showing a Chaos Pattern on Dermoscopy

“…Pigmented Bowen disease of the palm and sole is a rare subtype of Bowen disease that mimics melanoma [1,2]. Two previous reports described a multicomponent pattern with regularly distributed dotted vessels and peripheral parallel furrow/lattice-like pattern and/or parallel ridge pattern [1,2].…”
