“…8f), while TMEP is mainly characterised by reticular vessels on an erythematous/brownish base (“reticular vascular” pattern), sometimes associated with a brownish network [117–121]. However, dermoscopy cannot guarantee a reliable distinction of such conditions as, albeit uncommonly, UP may display the reticular vascular pattern as well [117].…”

Over the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides and subacute cutaneous lupus erythematosus), papulosquamous/papulokeratotic dermatoses (lichen planus, pityriasis rosea, papulosquamous sarcoidosis, guttate psoriasis, pityriasis lichenoides chronica, classical pityriasis rubra pilaris, porokeratosis, lymphomatoid papulosis, papulosquamous chronic GVHD, parakeratosis variegata, Grover disease, Darier disease and BRAF-inhibitor-induced acantholytic dyskeratosis), facial inflammatory skin diseases (rosacea, seborrheic dermatitis, discoid lupus erythematosus, sarcoidosis, cutaneous leishmaniasis, lupus vulgaris, granuloma faciale and demodicidosis), acquired keratodermas (chronic hand eczema, palmar psoriasis, keratoderma due to mycosis fungoides, keratoderma resulting from pityriasis rubra pilaris, tinea manuum, palmar lichen planus and aquagenic palmar keratoderma), sclero-atrophic dermatoses (necrobiosis lipoidica, morphea and cutaneous lichen sclerosus), hypopigmented macular diseases (extragenital guttate lichen sclerosus, achromic pityriasis versicolor, guttate vitiligo, idiopathic guttate hypomelanosis, progressive macular hypomelanosis and postinflammatory hypopigmentations), hyperpigmented maculopapular diseases (pityriasis versicolor, lichen planus pigmentosus, Gougerot-Carteaud syndrome, Dowling-Degos disease, erythema ab igne, macular amyloidosis, lichen amyloidosus, friction melanosis, terra firma-forme dermatosis, urticaria pigmentosa and telangiectasia macularis eruptiva perstans), itchy papulonodular dermatoses (hypertrophic lichen planus, prurigo nodularis, nodular scabies and acquired perforating dermatosis), erythrodermas (due to psoriasis, atopic dermatitis, mycosis fungoides, pityriasis rubra pilaris and scabies), noninfectious balanitis (Zoon’s plasma cell balanitis, psoriatic balanitis, seborrheic dermatitis and non-specific balanitis) and erythroplasia of Queyrat, inflammatory cicatricial alopecias (scalp discoid lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia and folliculitis decalvans), nonscarring alopecias (alopecia areata, trichotillomania, androgenetic alopecia and telogen effluvium) and scaling disorders of the scalp (tinea capitis, scalp psoriasis, seborrheic dermatitis and pityriasis amiantacea).

“…However, dermoscopy cannot guarantee a reliable distinction of such conditions as, albeit uncommonly, UP may display the reticular vascular pattern as well [117]. Other less frequent vascular findings visible in both UP and TMEP include sparse dotted vessels and thin and tortuous linear vessels [117–121]. …”

“…When it comes to TMEP, a systematic review revealed 13 cases from five studies, including one case limited only to acral areas. The three main dermoscopic patterns were reticular vascular pattern (thin reticular telangiectasias) observed in all cases, in three cases associated with an erythematous background, in two cases with pigment network (brown reticular lines), and in one with brownish background [ 9 , 10 , 11 , 12 ] ( Figure 3 ).…”

“…According to the current World Health Organization (WHO) classification, CM is divided into three forms: maculopapular cutaneous mastocytosis (MPCM) (including clinical subtypes previously known as urticaria pigmentosa [UP] and telangiectasia macularis eruptiva perstans [TMEP]), diffuse cutaneous mastocytosis (DCM), and mastocytoma of the skin [ 5 ]. Other clinical variants of CM have been described, e.g., nodular mastocytosis, plaque-type mastocytosis, pseudoangiomatous xanthelasmoid mastocytosis, and pseudoxanthomatous localised mastocytosis, though they are no longer recognised as separate entities but as clinical subtypes of either MPCM or mastocytoma based on the number of the lesions (>5 MPCM and ≤5 mastocytoma) [ 2 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. The diagnosis of cutaneous mastocytosis is generally based on clinical assessment (presentation of cutaneous lesions, positive Darier’s sign, and symptoms arising from mediator release) in association with additional investigations, such as histopathological, immunohistochemical, and sometimes genetic assessment.…”

The term mastocytosis refers to a heterogeneous group of disorders characterised by accumulation of clonal mast cells in different organs, most commonly in the skin. Little is known about the role of dermoscopy in the diagnostics of mastocytosis. To date, no systematic review on the dermoscopic features of cutaneous mastocytosis has been performed. The aim of this study was to summarise the current knowledge in the field as well as to identify the knowledge gaps to show possible directions for further studies, based on a systematic search of PubMed, Scopus, and Web of Science databases and related references published before 3 January 2022. Dermoscopic features, type of dermoscope, polarisation mode, magnification, and number of cases were analysed. In total, 16 articles were included in this review (3 case series and 13 case reports), analysing 148 patients with different variants of cutaneous mastocytosis; all of the studies analysed had a low level of evidence (V). The main dermoscopic features of urticaria pigmentosa included brown structureless areas, brown lines arranged in a network, and linear vessels distributed in a reticular pattern, with this last finding also being typical of telangiectasia macularis eruptiva perstans. The presence of either circumscribed yellow structureless areas or diffuse yellowish background was a constant pattern of mastocytoma, while nodular, pseudoangiomatous xanthelasmoid, and plaque-type mastocytosis were typified by light-brown structureless areas and/or pigment network, though the first two variants also showed yellow/yellow-orange structureless areas. Finally, pigmented streaks of radial distribution surrounding hair follicles were described to be a pathognomonic dermoscopic feature of pseudoxanthomatous mastocytosis. Although this review shows that the various clinical forms of cutaneous mastocytosis may feature diagnostic dermoscopic clues, it also underlines the need for further investigation as several relevant data are missing, including evaluation of dermoscopic pattern according to anatomical locations or “lesion age”, studies on rare mastocytosis variants, evaluation of the prognostic role of dermoscopy in the context of systemic involvement, and comparative analyses with common clinical mimickers.
