“…There is mounting evidence that the prevalence and morphological appearance of skin tumours are strongly influenced by age, pigmentary trait and the anatomical location at which the tumour arises. [1][2][3][4][5] Body regions that influence the frequency and morphology of skin tumours are commonly referred to as special body sites. 6 Moreover, it is well documented that the clinical and histopathological diagnosis of tumours arising at special body sites may be challenging.…”

Our study suggests that a high number of facial naevi could predict a high total naevus count. Moreover, naevi present a different morphological appearance during lifetime being initially flat, small and pigmented and becoming later raised, large and hypopigmented. Instead, lentigo maligna is an intraepidermal proliferation that typically presents as flat, large pigmented macule. A given histopathological diagnosis of a junctional naevus of a flat, facial pigmented macule of an elderly should be critically reviewed and treated with caution.

“…This is in line with evidence from the literature. For example, blurred vascular structures and "reticular white lines"/"lines, reticular, hypopigmented, around brown clods" (negative pigment network), commonly found respectively in dermal nevi and dermatofibromas in light phototypes, have been reported less frequently in skin of color [13][14][15].…”

Introduction: A structured set of eight basic dermoscopic parameters (lines, clods, dots, circles, pseudopods, structureless, else, and vessels) including a total of 77 variables with corresponding descriptive and metaphoric vocabulary has been released for evaluation of skin tumors by the International Dermoscopy Society (IDS). Objectives: To validate the aforementioned criteria for the use in darker phototypes (phototypes IV-VI) via an expert consensus. Methods: The two-round “Delphi method” was adopted, with an iterative process including two rounds of email questionnaires. Potential panelists were asked to take part to the procedure via email on the basis of their expertise on dermoscopy of skin tumors in dark phototypes. Results: A total of 17 participants were involved. All the original variables of the eight basic parameters reached agreement during the first round, except for “pink small clods” (“milky red globules”) and “structureless pink zone” (“milky red areas”). Moreover, during the first round, panelists proposed a change of three existing items and the introduction of four new items, i.e., “black, small clods” (“black globules”), “follicular plugs”, “erosions/ulcerations”, and “white color around vessels” (“perivascular white halo”). All such proposals achieved agreement, thus being included in the final list, for a total of 79 items. There was consistency between descriptive and metaphoric approach in terms of scoring. Conclusions: Albeit most of the original items were considered applicable even for skin of color, there are some points of differences that physicians need to know. No significant preference was found between descriptive and metaphoric terminology among panelists.

“…The literature published on dermoscopy in darker skin has primarily included melanomas, benign pigmented lesions, and dermatosis papulosa nigra. 22 Several studies conclude that these features are very similar to those in lighter 23 With these similarities in mind, we hope to have a better understanding of characteristic features of cutaneous lymphomas with other imaging modalities, and how they may guide diagnosis in patients with darker skin types. The use of dermoscopy for patients with darker skin has also been explored in studies on alopecia.…”

Cutaneous lymphomas in African American/Black patients: pitfalls and presentations

This review describes and highlights differences in clinical presentations of cutaneous lymphomas (CLs), particularly in darker skin types, i.e., Skin of Color (SOC). We illustrate differences in clinical features on physical exam that can be a diagnostic challenge and suggest ways to recognize and identify these conditions at an early stage through a high level of suspicion. The review includes a summary of the epidemiology of various CLs, specifically highlighting the presentation and incidence in African American/Black patients, where the data are available. We also include a discussion of adult HTLV-1-associated T-cell leukemia/lymphoma (ATLL) which, although a systemic T-cell lymphoma, may present with skin manifestations and mimic MF, other CTCL subtypes, or other inflammatory dermatoses. Finally, this review highlights the possible use of imaging modalities, such as dermoscopy and reflectance-confocal microscopy, in diagnosing and recognizing cutaneous lymphomas in patients with darker skin types. MethodsWe conducted a search with an MSKCC librarian on cutaneous lymphomas and lymphoproliferative disorders using Scopus, Embase, Ovid, and Google Scholar to identify publications in English. Our search term keywords were restricted to Mycosis Fungoides, S ezary syndrome, primary cutaneous anaplastic large-cell lymphoma, lymphomatoid papulosis, subcutaneous panniculitis-like T-cell lymphoma, primary cutaneous follicle center lymphoma, primary cutaneous marginal zone B cell lymphoma, and primary cutaneous diffuse large B-cell lymphoma, leg type, for which MSKCC Dermatology Service has corresponding clinical images. We expanded our search to include literature on dermoscopy and imaging modalities using these search terms and variations, including dermatoscope, imaging, and confocal. The returned publications were reviewed and sorted by relevance to Skin of Color. at the time of diagnosis. 2 Cutaneous T-cell lymphomas (CTCL) are the most common, with a reported incidence of 6.4 per 100,000, according to data from the Surveillance, Epidemiology, and End Results registry (SEER). 3 From the same data, the incidence of cutaneous B-cell lymphomas (CBCL) is estimated at 3.3 per 100,000. 4 While cutaneous lymphomas may occur in patients of all races, the majority of patients with CLs in the United States are White, reflecting the racial make-up of the country in past years.Mycosis fungoides (MF) is the most common type of CTCL, representing about 57% of all CTCL. The ratio of incidence of MF in African American/Black (which we will refer to as Black

Dermoscopic nevus patterns in skin of colour: a prospective, cross‐sectional, morphological study in individuals with skin type V and VI

Abstract: Our study provides new insights into the nevus pattern in individuals with a dark pigmentary trait, which may aid the diagnosis and management of nevi in this patients group.
