Description The use of dermoscopy is not limited to the dermato-oncology field. Inflammoscopy is the dermoscopic evaluation of inflammatory dermatoses and can provide valuable information for diagnosis and follow-up (table 8) (Sgouros et al., 2018).

Psoriasis[edit | edit source]

Monomorphic red dots[edit | edit source]

Monomorphic and symmetrically distributed red dots over an erythematous background together with white scaling are the hallmark pattern of psoriasis. Histologically, they correspond to the presence of spiraled capillaries in the papillary dermis and psoriasiform epidermal hyperplasia and parakeratosis (Sgouros et al., 2018).

Dermatitis / Excema[edit | edit source]

Irregularly distributed red dots[edit | edit source]

Irregularly distributed red dots and yellow crusts/scales are the most common dermoscopic features of dermatitis (allergic/contact dermatitis, atopic dermatitis and seborrheic dermatitis). Yellow crusts/scales are more frequent in the acute stages of dermatitis (Lallas et al., 2012). Histologically, irregular red dots correspond to slight dilatation of the subpapillary vessels, and yellow crusts/scale, to the epidermal spongiotic reaction (Goncharova et al., 2015; Sgouros et al., 2018).

Lichen Planus[edit | edit source]

Peripheral dotted vessels[edit | edit source]

Peripheral dotted/linear vessels together with round, linear, reticular or annular pearly- whitish structures are characteristic of lichen planus (A. Lallas et al., 2014). Histopathologically, whitish structures reveal compact orthokeratosis above zones of wedge-shaped hypergranulosis and acanthosis and are the equivalent of Wickham striae (Vázquez-López et al., 2003).

'Polygonal vessels[edit | edit source]

Polygonal vessels are lineal vessels arranged in horizontal and vertical lines forming a geometrical pattern. Polygonal vessels, in the absence of scales, are highly specific for erythemato-telangiectatic rosacea. Histologically, they correlate with increased vascularization (Sgouros et al., 2018).

Granulomatous disease[edit | edit source]

Orange-yellowish patches[edit | edit source]

Round to oval orange-yellowish patches are a characteristic dermoscopic finding in many granulomatous cutaneous disorders (leishmaniasis, sarcoidosis, lupus vulgaris, granuloma faciale, granulomatous rosacea, granuloma annulare). Histologically, they correlate to granulomas located superficially in the dermis (Bañuls et al., 2015).
