OBJECTIVES To assess the margins required for excision of lentigo maligna (LM) and lentigo maligna melanoma (LMM) by the technique of mapped serial excision (MSE), and to assess the efficacy of MSE. DESIGN An interventional, prospective, noncontrolled case series. SETTING Tertiary referral, dermatologic surgery unit. PATIENTS Consecutive patients with head and neck LM or LMM who underwent...

BACKGROUND Low fluence 1,064 nm Q-switched (QS) Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser treatment, also known as laser toning, is widely used for pigmentary disorders. There has been no reliable evaluation of the effect of low fluence 1,064 nm QS Nd:YAG laser for senile lentigo. OBJECTIVE To investigate the beneficial effect of low fluence 1,064 nm QS Nd:YAG laser in the treatment of...

A solar lentigo is a flat, sharply circumscribed patch. It can be round, oval or irregular in shape. Color varies from skincolored, brown to dark brown or black, and size varies from a few millimeters to several centimeters in diameter [1, 2].

The clinical diagnosis was suggestive of a solar lentigo (SL) because of the symmetric shape, the regular border, and the homogenous brown colo...

Focal dermal hypoplasia or Goltz syndrome is a rare X-linked genodermatosis characterized by cutaneous and musculoskeletal defects. Dermoscopy is a noninvasive auxiliary method for the diagnosis of lesions, whether melanocytic or not. Its widespread use in dermatology is resulting in the description of new patterns and characterization of lesions not reported before its use. A typical case of G...
