Dermoscopy in black people

Objective: To review recent dermoscopy studies that provide new insights into the evolution of nevi and their patterns of pigmentation as they contribute to the diagnosis of nevi and the management of pigmented melanocytic nevi. Data Sources: Data for this article were identified by searching the English and German literature by Medline and Journals@Ovid search for the period 1950 to January 2009. Study Selection: The following relevant terms were used: dermoscopy, dermatoscopy, epiluminescence microscopy (ELM), surface microscopy, digital dermoscopy, digital dermatoscopy, digital epiluminescence microscopy, digital surface microscopy, melanocytic skin lesion, nevi, and pigmented skin lesions. There were no exclusion criteria. Data Synthesis: The dermoscopic diagnosis of nevi relies on the following 4 criteria (each of which is characterized by 4 variables): (1) color (black, brown, gray, and blue); (2) pattern (globular, reticular, starburst, and homogeneous blue pattern); (3) pigment distribution (multifocal, central, eccentric, and uniform); and (4) special sites (face, acral areas, nail, and mucosa). In addition, the following 6 factors related to the patient might influence the pattern of pigmentation of the individual nevi: age, skin type, history of melanoma, UV exposure, pregnancy, and growth dynamics. Conclusions: The 4×4×6 “rule” may help clinicians remember the basic dermoscopic criteria of nevi and the patient-related factors influencing their patterns. Dermoscopy is a useful technique for diagnosing melanocytic nevi, but the clinician should take additional factors into consideration to optimize the management of cases of pigmented lesions.

“…44,45 Scope et al 38 found a significantly higher frequency of small reticular nevi on children aged 10 to 11 years with dark skin than on those of the same age with fair skin. 38 Our group observed significant skin type-related differences in color and pigment distribution in an adult study population (mean age, 34 years).…”

“…Giorgi et al 10 Zalaudek et al 11 demonstrated, in a multicenter study, that individuals with different skin types are prone to different nevus types in terms of pigment distribution, color, and, to a certain extent, the global dermoscopic pattern. However, the study was conducted in white people, with skin types I to IV.…”

Dermoscopy has dramatically developed, becoming a well-established routine technique in many countries in the mid-1980s. Dermoscopy allows physicians to observe structures and colors otherwise not visible to unaided eyes, increasing melanoma diagnostic accuracy by up to 35%. Moreover, dermoscopy allows for increases in the number of diagnosed and excised melanomas together with a reduction in the number of unnecessary excisions. New data are continuously acquired mostly on melanoma diagnosis, follow-up of melanocytic lesions and nevogenesis. Short-term 3-month follow-up is the optimum time interval for identifying minimal changes in featureless melanomas. Nevertheless, long-term follow-up is similarly useful for the recognition of changes in melanomas with very low rates of growth. In the last few years a huge number of publications on dermoscopy have been published. The aim of this review is to summarize the most important recent advances in dermoscopy.

Dermoscopy in black people

Abstract: Darker pigmentation of the skin does not impede the identification of single dermoscopic features. As in lighter-skinned populations, dermoscopy in black people can also lead to early and accurate diagnosis of melanoma, thereby significantly reducing the number of unnecessary excisions.
