Abstract
FONTAINE PEREZ, Yaima et al. Usefulness of Dermatoscopy in the clinical and histological correlation of Pigmented Nevi. Rev Cubana Invest Bioméd [online]. 2021, vol.40, n.2 Epub June 01, 2021. ISSN 1561-3011.
Introduction:
The diagnostic precision of pigmented nevi has been a constant concern of dermatologists.
Objective:
To determine the usefulness of the Dermatoscope in the correlation of the clinical characteristics and the dermoscopic patterns of pigmented nevi and their association with the histological diagnosis.
Methods:
An analytical observational investigation of a correlational type was carried out in patients from the southern area of Ciego de Ávila who attended the Dermatology consultation at the Antonio Luaces Iraola Provincial Hospital in the period from April 2017 to December 2019.
Results:
The female sex, the age group of 21 to 30 years, skin phototype II and the exposed area (face and V of the neckline) (18; 35.3%) predominated with no relationship between these variables. The histological diagnosis of junctional nevus was found associated with symmetry (p <0.004), homogeneous pigmentation (p <0.000), as well as the reticular dermoscopic pattern (p <0.000), globular (p <0.002) and homogeneous (p <0.008). The intradermal nevus was observed associated with the clinical characteristic of homogeneous pigmentation (p <0.007), and with the reticular (p <0.000) and homogeneous (p <0.005) dermoscopic pattern. The composite nevus was not related to clinical or dermoscopic characteristics. The blue nevus only correlated with the homogeneous dermoscopic pattern (p <0.025).
Conclusions:
The dermoscopic patterns were useful for the clinical and histological diagnosis of pigmented nevi.
