Background: Although choosing the appropriate treatment method is relatively easy for papular or protuberant lesions, for small macular lesions it may not be so, because they are generally percepted as mild lesions by the patient and she/he usually has the anxiety of final disfigurement which may result esthetically worse than the original one. It is reasonable to choose the method which will reveal the least scar formation and lowest recurrence rate with cost‐effectiveness, in removal of superficial small macular lesions for cosmetic purposes. Methods: Fifty‐six male and female patients with small hyperpigmented flat or macular lesions, less than or equal to 5 mm diameter on their face, who referred to hospital dermatology clinic for removal and received an interventional therapy with a radio‐wave surgery unit in the years 2018–2019 were retrospectively recruited. Besides the observation of scar formation and residual erythema, 3‐month recurrence rates were also analyzed. Results: At the end of 3 months, there was no scar on any lesion site. Mild erythema was detected on 15 lesion sites out of a total of 218 (6.9%).The total recurrence rate was 7.7%. The mean age of the patients with at least one recurrence was significantly greater than the patients with no recurrence, and the lesions greater than 3 mm were more prone to recur than the lesions less than or equal to 3 mm. Conclusion: Although no method of lesion removal can warrant a scarless result without recurrence, for benign macular hyperpigmented lesions of the face up to 5 mm in diameter, radio‐wave surgery may be preferred due to both its minimal scar formation and recurrence rate, in addition to its cost‐effectiveness.

Abstract: The report discusses a solitary pigmentation on the dorsal tongue of an adult female, featuring variably concentrated melanocytes, hyperpigmened keratinocytes and pigmentary incontinence spatially related to fungiform and adjacent filiform papillae. Interpretations included lentigo simplex and pigmented fungiform papilla, and are critically discussed in conjunction with clinical considerations. [ABSTRACT FROM AUTHOR]

The case report of a 58 years white patient is presented with a history of disk herniation in cervical and lumbar regions, who 2 years ago attended the Dermatology Service due to a color change in the fingernail of the third finger of her right hand, symptoms that belonged to a lentigo simplex. In this occasion she presented destruction of the ungueal bed and increase of color which covers the whole fingertip, so another biopsy was carried out and the histological diagnosis of acral lentiginous melanoma (in situ) was confirmed.

Oral mucosa pigmentations belong to a heterogeneous variety of lesions, which are usually divided into two groups: exogenous or endogenous pigmentations. The pigmented lesions most frequently found in the oral mucosa are the amalgam tattoo, the melanotic macula and the nevus. All these lesions may affect every part of the oral mucosa, and they may represent a hard diagnostic challenge for the clinician; the clinical objective examination is not sufficient to make a correct diagnosis. Reflectance Confocal Microscopy provides a real-time microscopic evaluation of tissue layers, and is widely considered a useful auxiliary tool in monitoring skin and mucosa lesions. In this context, Reflectance Confocal Microscopy imaging is a valid aid in the management of oral mucosa pigmented lesions, to corroborate and support the diagnostic process., (Copyright 2019 Biolife Sas. www.biolifesas.org.)
