Abstract
SUMMARY
Dermoscopy is a non-invasive diagnostic device for the in vivo observation of pigmented skin lesions, allowing a better visualization of surface and subsurface structures. This diagnostic tool permits the recognition of morphologic structures not visible by the naked eye, thus opening a new dimension of the clinical morphologic features of pigmented skin lesions.
Dermoscopy is particularly useful in evaluating of facial pigmented lesions. Pigmented lesions of face have a diagnostic challenge which may requires invasive biopsies for confirmation of diagnosis. There are many causes of facial pigmented lesions as melasma, nevi, PIH, ALP, SL and other causes.
The aim of this work was screening of facial pigmented lesions in a sample of Egyptians using dermoscope to demonstrate the prevalence of facial pigmented lesions.
One hundred and four Egyptian patients with 159 different facial pigmented lesions were included in this study. All patients were subjected to complete history taking, thorough general and dermatological examination, patients were examined for number, site, size and color of lesions.
Dermoscopic examination was done to describe different dermoscopic patterns of these lesions. Digital photographs of the lesions and their dermoscopic patterns were taken. Histopathological examination was done to confirm the diagnosis and to correlate between dermoscopic and histopathologic findings.
Results of this study included:
The clinical diagnosis of the studied 104 patients with 159 different facial pigmented lesions was divided into 2 groups:
