Warty Dyskeratoma (WD) is a rare condition consisting in single or multiple papular or nodular lesions of the skin or of the oral mucosamucosa. Histologically, a cup-shaped epidermal invagination centred by a plug of epidermal hyperparakeratosis with suprabasal acantholysis and dyskeratosis is typically observed. A case of post-inflammatory WD, which was also observed by dermoscopy, is described. Dermoscopy showed an eight-shape whitish collarette surrounded by light brown pigmentation. A central white structureless area with an adjacent rosette were observed. Some small rust-coloured blood crusts were also observed in the centre of the lesion; no prominent vascular pattern was detected. The etiopathogenesis of this benign neoplasm could be multifactorial. Dermoscopy of WD is not specific but may help to ruling out other skin tumors. n

Abstract
Warty Dyskeratoma (WD) is a rare condition consisting in single or multiple papular or nodular lesions of the skin or of the oral mucosamucosa. Histologically, a cup-shaped epidermal invagination centred by a plug of epidermal hyperparakeratosis with suprabasal acantholysis and dyskeratosis is typically observed. A case of post-inflammatory WD, which was also observed by dermoscopy, is described. Dermoscopy showed an eight-shape whitish collarette surrounded by light brown pigmentation. A central white structureless area with an adjacent rosette were observed. Some small rust-coloured blood crusts were also observed in the centre of the lesion; no prominent vascular pattern was detected. The etiopathogenesis of this benign neoplasm could be multifactorial. Dermoscopy of WD is not specific but may help to ruling out other skin tumors. nI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
