Accuracy of dermoscopic criteria for the differentiation between superficial basal cell carcinoma and Bowen's disease

Abstract

Dotted and glomerular vessels are strong predictors of BD. When located on the lower extremities, sBCC may also display dotted vessels, rendering its recognition problematic. On the latter anatomic site, clinicians should consider SFT and whity shiny blotches/strands as additional sBCC predictors.

Minimizing the dermatoscopic morphologic overlap between basal and squamous cell carcinoma: a retrospective analysis of initially misclassified tumours

“…Both of the studies suggested that dotted vessels are mainly seen in BCCs located on the lower legs. 10,15 Indeed, also in our sample, dotted or glomerular vessels were found in all BCCs located on the lower legs (9/9, 100.0%) and in 53.1% of BCCs located on other anatomic sites. Overall, our results suggest that no single morphologic type of vessels can be considered as an absolute and specific feature of one diagnosis only.…”

“…The frequencies of criteria found in BCC and SCC differ from other studies, but this is expected and related to the study design. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Specifically, in this study we included only tumours that were clinically and dermatoscopically misdiagnosed, which means that by definition they did not display the expected dermatoscopic pattern.…”

Dermoscopic features of psoriasis of the skin, scalp and nails – a systematic review

“…According to Lallas et al ,. the presence of dotted vessels alone is insufficient to establish a diagnosis of psoriasis, as this finding may be seen in other inflammatory skin conditions, such as lichen planus, pityriasis lichenoides chronica, pityriasis rosea, dermatitis, pityriasis rubra pilaris, porokeratosis and Bowen's disease. Detailed data on dermoscopic differential diagnosis are presented in Table .…”

Dermatoscopic features of thin (≤2 mm Breslow thickness) vs. thick (>2 mm Breslow thickness) nodular melanoma and predictors of nodular melanoma versus nodular non‐melanoma tumours: a multicentric collaborative study by the International Dermoscopy Society

“…8 Dotted vessels can be found in several benign and malignant skin tumours and inflammatory skin diseases (i.e. common nevi, Spitz nevi, dermatofibromas, lichen planus-like keratosis, Bowen's disease, superficial BCCs on the legs, psoriasis, eczema) [26][27][28][29][30][31] as well as in flat pigmented and amelanotic melanoma. 10,32 However, almost all of the aforementioned conditions manifest as clinically flat lesions, whereas dotted vessels in nodular tumours have not been frequently described.…”
