Abstract:
Objective:To preliminarily investigate dermoscopic characteristics of trichoblastoma, and to provide ideas for clinical diagnosis of trichoblastoma.Methods:Clinical data were collected from 5 patients with trichoblastoma who underwent both dermoscopic and histopathological examinations in Wuhan No.1 Hospital from November 2018 to July 2021, and dermoscopic features were analyzed retrospectively.Results:According to the presence or absence of pigments, trichoblastoma was divided into 2 subtypes: pigmented trichoblastoma (3 cases) and non-pigmented trichoblastoma (2 cases) . Dermoscopic examination of the 3 cases of pigmented trichoblastoma showed blue-gray ovoid nests (3 cases) , arborizing vessels (2 cases) , blue-gray globules (2 cases) , bright white structureless areas (2 cases) , concentric structures (1 case) and ulcers (1 case) ; no yellow-whitish homogenous structure was found. As for non-pigmented trichoblastoma, dermoscopic features included arborizing vessels (2 cases) , yellow-whitish homogenous structures (2 cases) , bright white structureless areas (2 cases) and blue-gray globules (1 case) ; no ulcers or blue-gray ovoid nests were observed in either case.Conclusion:Dermoscopic patterns differ between pigmented and non-pigmented trichoblastoma, so dermoscopy can provide preliminary diagnostic clues for trichoblastoma.
