Scabies is a contagious cutaneous infection, caused by burrowing of the mite Sarcoptes scabiei var. hominis in the epidermis. The clinical suspicion is due to the history, clinical distribution of lesions and its aspect; however, the confirmation is with the detection of the parasite. We present the features of the diagnostic methods for scabies, from its detection through direct microscopy of skin scrapings from a lesion or with the use of an adhesive tape on the lesions, to its detection using the dermatoscope, a tool available in most dermatology clinics, which, even in unexperienced hands, has acceptable sensitivity and specificity.

Nasal surgical defects resulting from the removal of non-melanoma skin cancer represent a challenge for the surgeon due to the anatomical complexity and the high functional and aesthetic relevance of the region.The purpose of this paper is to demonstrate the jigsaw puzzle advancement flap. Resection of basal cell carcinoma was performed in the patient's perialar region, followed by the reconstruction with the jigsaw puzzle advancement flap, with excellent aesthetic and functional results.The presented technique is useful and not yet widespread, and it should be part of the dermatological surgeon's arsenal in the reconstruction of surgical defects located in the nasal ala-perialar region.

Intense Pulsed Light (IPL) is an effective technology to treat vascular lesions, pigmented lesions, and photorejuvenation, among other indications. In the case of telangiectasia, its mechanism of action is based on photothermolysis of the vessels, inducing intravascular coagulation. We report three cases where IPL was used to treat telangiectasia in a surgical scar, showing good aesthetic results after three sessions.

Facial erythema after phenol peeling is one of the expected effects of the healing process and collagen formation. Intense Pulsed Light (IPL) therapy is one of the forms used as a treatment accelerating recovery, reducing redness, inflammation, and itching symptoms that may occur after peeling. IPLT can also be used to treat hypertrophic scars, which is also one of the adverse events that can happen with deep peeling. We report a successful case of IPLT treatment in a patient who presented facial erythema and hypertrophic scarring after undergoing phenol peeling.
