Background Giant congenital melanocytic naevi (CMN) are often disfiguring, potentially malignant pigmented lesions present at birth. Their management is based on two main considerations: attempt to minimize the risk of malignancy and to obtain an acceptable cosmetic result. In the past various approaches have been used to treat these naevi.

Background Nevoid basal cell carcinoma syndrome (NBCCS) is characterized by the development of multiple basal cell carcinomas (BCCs). A major problem for these patients is the enormous amount of BCCs which can invade in the deep underlying structures, especially in the face. Different treatment modalities are used in these patients; surgical excision, Mohs micrographic surgery, cryotherapy, photodynamic therapy, ablative laser therapy and topical 5% imiquimod. There is no evidence based advice how to treat a NBCCS patient.

Background and Objectives Childhood hemangioma is the most common soft tissue tumor of infancy, occurring in 10% of children younger than 1 year old. Ten percent of these infantile hemangiomas involute yearly without intervention. Treatment with the pulsed dye laser (PDL) is the criterion standard for treating vascular lesions. It is well established as the most effective, safest treatment for port‐wine stains. Previous studies of the use of PDL treatment in superficial hemangioma showed inconsistent results. Main objectives were to compare the efficacy and adverse effects of PDL treatment with those of observation in the treatment of superficial hemangiomas. Parental quality of life was also assessed. Materials and Methods This was a prospective, randomized, controlled trial in which we enrolled 22 infants aged 1.5 to 5 months old with early hemangiomas with a maximum diameter of 5 cm. We assigned the infants to PDL treatment (n = 11) or observation (n = 11), and followed up until the age of 1 year. Patients in the intervention group were treated using a 595‐nm PDL (VBEAM, Candela Corp., Wayland, MA) with a 7‐mm spot diameter, 30/10 to 40/10‐ms epidermal cooling, a 7‐ to 15‐J/cm2 fluence range, and a pulse duration of 0.45 to 40.0 ms. During follow‐up, color measurements were made (Colori meter; Minolta, Tokyo, Japan), and surface area and echo depth of the hemangioma were determined. Results No significant differences were seen between the groups at time of inclusion or at the age of 1 year in echo depth (p = .66) or surface area (p = .62). Results were significant for color difference (p = .03) between PDL treatment and observation. Cosmetic outcome judged by an independent panel consisting of a dermatologist, physician assistant, dermatology resident, dermatology nurse, and plastic surgery resident was significantly better in the PDL treatment group (46%) than in the observation group (18%) (p = .006). Conclusions Pulsed dye laser is only to be considered as an alternative treatment up to the age of 6 months, at which time parents and physicians consider cosmetic outcome to be a relevant factor, but laser therapy plays a major role in the treatment of residual lesions at older ages.

Background Imiquimod 5% cream can reduce or clear superficial and small nodular basal cell carcinoma (BCC). It could be used as a pretreatment of Mohs micrographic surgery (MMS) to decrease defect size.

It is known that the incidence of skin cancer is rising rapidly worldwide, but no reliable figures on multiple nonmelanoma skin cancer (NMSC) are available.

Photodynamic therapy (PDT) with light emitting diode (LED) illumination is a frequently used treatment modality for actinic keratosis (AK) with excellent cosmetic outcome. A major disadvantage, however, is the high pain score. Pulsed dye laser (PDL) illumination has been suggested, but the long-term efficacy of this treatment is unknown. In this split-face study we prospectively treated 61 patients with AK, with both LED-PDT and PDL-PDT. The mean change in the number of lesions between the end of follow-up and start of therapy was -4.25 (95% confidence interval (95% CI) -5.07; -3.43) for LED-PDT and -3.88 (95% CI -4,76; -2.99) for PDL-PDT, with a non-significant difference (p = 0.258) of -0.46 (95% CI -1.28; 0.35). The percentage decrease from baseline in the total number of AK was 55.8% and 47.8%, respectively, at 12-month follow-up. Visual analogue scale pain score was lower after PDL (mean 2.64) compared with LED illumination (mean 6.47). These findings indicate that PDL-PDT is an effective alternative illumination source fo.

BACKGROUND Although most cases of basal cell carcinoma (BCC) are curable, facial and recurrent BCCs require time consuming and labor-intensive Mohs micrographic surgery (MMS) to ensure complete removal with optimal cosmetic results. To handle the skin cancer epidemic, there is an urgent need to speedup MMS. Recently, rapid lump examination (RLE) has been shown to enable quick histologic examination, but its usefulness within MMS is unknown. OBJECTIVE To evaluate the accuracy of RLE for the detection of residual BCC during MMS. MATERIALS AND METHODS Twenty-two BCCs of various subtypes were evaluated by means of RLE and standard fresh frozen section (FFS) examination. For RLE, the freshly excised tissue was stained with toluidine blue and imaged with a stereomicroscope before being subdivided into sections suitable for processing into FFS. Fresh frozen sections were stained with hemotoxylin and eosin and evaluated with light microscopy. RESULTS Using FFS examination as the gold standard for the detection of residual BCC, RLE had a sensitivity, specificity, positive predictive value, and negative predictive value of 83.8%, 94.0%, 83.8%, and 94.0%, respectively. CONCLUSION As RLE enables quick 3-dimensional visualization of surgical margins for the detection of residual BCC, it holds the potential to speedup histologic examination during MMS.
