Dermoscopic observation of Bowen's disease

Abstract

Dermoscopically, BD is mainly characterized by a multicomponent global pattern associated with a prominent vascular pattern (mainly dotted vessels) and a scaly surface. Although no specific dermoscopic criteria can be given for BD, epiluminescence can be a valuable aid in the diagnosis of such a mimicker lesion.

Dermatoscopy of pigmented Bowen's disease

“…Previous published reports have been case studies and one series of 14 cases. [1][2][3][4][5][6][7][8] In a review of 420 cases of BD, only 7 (1.7%) were pigmented. 5 Our findings are markedly different.…”

“…Previous descriptions of the dermatoscopy of pBD have been case reports and small case series. [1][2][3][4][5][6][7][8] Our study describes the dermatoscopic patterns of pBD in a series of 52 cases and correlates these findings with histopathology.…”

Dermatoscopy: Alternative uses in daily clinical practice

“…88 At dermatoscopic examination, Bowen's disease displays atypical vascular structures, with a preponderance of dotted/glomerular vessels, and a scaly surface occurring in up to 90% of cases. [88][89][90][91][92] In pigmented Bowen's disease, small brown globules in a patchy distribution, a gray-brown diffuse pigmentation, and a pigmented pseudonetwork represent the most remarkable dermatoscopic findings. 88,91 Dermatoscopy has been considered to be of help in preoperatory evaluation, in follow-up, and in monitoring the nonsurgical outcome of the disease, in which the disappearance of vascular structures may indicate adequate treatment.…”

“…[15][16][17] If there is diagnostic doubt, or if confirmation is required before proceeding with a certain type of treatment, a punch biopsy can be performed. This is preferable to a curette biopsy, as the full thickness of the epidermis and dermis can be viewed to establish whether there is any invasive disease amounting to a cutaneous SCC.…”
