RESUMO -A mancha mongólica é uma forma de melanose dérmica comum em recém-nascidos, tendo uma incidência e prevalência variável consoante a raça, sendo menos frequente em crianças caucasianas. Apesar de tradicionalmente interpretadas como benignas, várias publicações têm vindo a sugerir que manchas mongólicas extensas, múltiplas, presentes em locais atípicos e persistentes ao longo da primeira infância podem estar associadas a algumas doenças metabólicas. Contudo, esta associação não está ainda bem esclarecida. Por outro lado, casos pontuais reportados na literatura têm descrito um tipo particular de mancha mongólica sobreposta a outra de pigmentação diferente, não sendo conhecido o mecanismo fisiopatológico e a relevância clínica deste achado. Os autores reportam o caso de um rapaz caucasiano com 7 meses de idade com manchas mongólicas múltiplas, extensas, de agravamento progressivo nos primeiros meses de vida, uma das quais mais pigmentada sobreposta a outra, localizada na anca direita.

“…The size of the Mongolian spot square was strongly and directly correlated with the body surface area of the infant (p=0.0001) (Figure 2 Several studies on prevalence of Mongolian spot have been conducted worldwide. The reported prevalence of the Mongolian spot variesas follows: East Africa (95.0%), Native Americans (90.0%), Korean (97.1%), China (86.3), Japan (81.5%), Nigeria (74.8%), Iran (71.3%), India (60.2-62.2%), Spain (60.0%), Taiwan (61.6%), Brazil (60.0%), Hungary (22.6%), Australia (25.5%), Italy (2-5%), Arab (8-10%), Azerbaijan (10%), and Turkey (10-12%) [2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Objectives:The aim of this study was to determine the prevalence and characteristics of Mongolian spots in Mongolian infants. Methods: This hospital-based, descriptive crosssectional study was conducted nationwide among 2641 newborn infants in Ulaanbaatar and in 21 provinces hospitals within 96 hours postpartum in 2015. Results: The prevalence of Mongolian spots in Mongolian infants was 91.3%. The prevalence of spots in females was 92.1% and in male newborns it was 90.6% (p>0.05). The prevalence of Mongolian spots in the Western provinces was lower than in the rest of other provinces (98.3% and 95% CI: 96.4-99.4). For of infants with Khalkha parentage, 92.7% had Mongolian spots, while 64.7% of infants with Kazakh parentage had Mongolian spots. The Mongolian spots are commonly located in infant's lower back (88.3%) and had an average length of 3.7±2.7 cm, width of 2.7±1.9 cm and an average area of 14.2±23.3 cm2. The appearance of Mongolian spots on the infant's legs, face, chest, hands, feet, knee, and cheeks were less frequent. Conclusion: The prevalence of Mongolian spots among Mongolian infants was 91.3% [95%CI: 87.2-95.3] and significant difference was observed between Mongolian and Kazakh infants.

“…Nevus spilus has been reported in association with congenital melanocytic nevus [10], as well as superimposed on or adjacent to other pigmentary disorders [11][12][13][14][15][16][17][18]. Mongolian spot has been described and associated with other pigmentary disorders [19][20][21][22][23][24][25]. Moreover, different associations of nevus anemicus with several pigmental anomalies [7,[26][27][28][29][30][31][32][33][34][35], as well as café au lait macule combined with different disorders of pigmentation [36,37].…”

“…All these previously cited associations have been considered by the authors as occasional associations of two paired nevoid pigmentary disorders and, only in few cases [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], explained as examples of twin-spotting phenomenon.…”
