Background And Aims: The selective removal of tattoos and benign cutaneous pigmented lesions with laser energy evolved rapidly with the development of the nanosecond-domain Q-switched laser (ns-laser). Recently, however, a series of picosecond-domain lasers (ps-lasers) with pulsewidths less than 1 ns has become commercially available, enabling more efficient and faster removal of pigmented lesions in the field of dermatologic laser surgery.

Rationale Behind The Ps-laser: The efficacy of the ns-laser depended on the theory of selective photothermolysis, whereby an extremely short pulse width was delivered less than the thermal relaxation time (TRT) of a target. Read More

Laser therapy has become a routine procedure in dermatological practice and is frequently also used for pigmented lesions. Few reports exist of melanomas diagnosed in lesions previously treated by laser therapy. Between 2007 and 2014, we identified 11 patients who presented to our department with a melanoma diagnosed in a region previously treated by laser therapy. Read More

Background/objective: Solar lentigines are benign pigmented lesions that occur mostly on sun-exposed areas. Q-switched and ablative lasers are effective for removing these lesions but the high incidence of postinflammatory hyperpigmentation raises concern in darker skin types. The objective of this study is to compare the efficacy and degree of postinflammatory hyperpigmentation with the Q-switched Nd:YAG and fractional carbon dioxide (CO2 ) laser for treatment of solar lentigines in Asians.

Background And Objective: Different subspecialists treat benign intraoral lesions using various approaches including surgical excision, medical therapy, sclerotherapy, and laser photocoagulation. The goal of this study was to establish whether lasers could effectively target and destroy oral lesions containing endogenous chromophores, while minimizing injury to unaffected adjacent tissues and critical structures.

Advances in laser technology in recent decades have increased the options for the treatment of dermatologic conditions of the eye and eyelid. Benign tumors can be laser-ablated with relative ease, and vascular and melanocytic lesions can be precisely targeted with modern lasers. In this contribution, we review treatment of periocular pigmented lesions, including melanocytic nevi and nevus of Ota; vascular lesions including telangiectasias, port wine stains, and infantile hemangiomas; hair removal; eyeliner tattoo removal; laser ablation of common benign periocular tumors, such as syringomas, xanthelasma, milia, and seborrheic keratoses; and laser resurfacing.

A nevus is described as a benign, often pigmented, skin growth that can be congenital or acquired. Different types of nevi are located at different depths within the skin. Traditional treatments for nevi include topical treatments, dermabrasion, and excision, which are generally ineffective, invasive, and often result in scars and dyspigmentation. Read More

Background: Skin resurfacing with the carbon dioxide (CO(2)) laser is currently a popular means of improving rhytides and scars and has been reported useful in the treatment for photodamaged skin, including precancerous and benign skin lesions, as well as superficial benign pigmented lesions.

Methods: We describe a 68-year-old man who developed rapid squamous cell carcinoma (SCC) on the resurfaced areas 3 weeks following CO(2) laser resurfacing.

Results: Rapid occurrence of SCC should be considered a rare complication, and we recommend carefully considering CO(2) laser resurfacing after excision of an SCC and surveying any cancer recurrences. Read More

Skin aging includes intrinsic aging, a universal and inevitable process attributable to the passage of the time alone; and photoaging, changes attributable to chronic sun exposure, which are neither universal nor inevitable. The major clinical features of aging skin include xerosis, laxity, wrinkles, slackness, and the occurrence of benign neoplasms such as seborrheic keratoses and cherry angiomas. Photoaging is characterized by dryness (roughness), actinic keratoses, irregular pigmentation (freckling, lentigines, guttate hypomelanosis, persistent hyperpigmentation), wrinkling, stellate pseudoscars, elastosis (fine nodularity and/or coarseness), inelasticity, telangiectasia, venous lakes, purpura (easy bruising), comedones (maladie de Favre et Racouchot) and sebaceous hyperplasia.

Background: The increasing use of lasers for the removal of pigmented skin lesions has led to a growing risk of erroneously treated malignant melanocytic tumours.

Patients And Methods: In two patients, both of whom developed a melanoma, the lesions were initially misdiagnosed clinically as a benign naevus and treated with laser vaporisation.

Results: On recurrence of the tumours, the diagnosis of melanoma was finally established by histological examination of the excised tumours in which differentiation from pseudomelanoma remained difficult. Read More
