Complete regression of a melanocytic nevus under intense pulsed light therapy for axillary hair removal in a cosmetic center.

Intense pulsed light (IPL) therapy using noncoherent broad-spectrum light has been reported to be effective for hair removal, and also for treating superficial pigmented lesions like ephelides and solar lentigines. We report complete regression of a pigmented melanocytic nevus, histologically confirmed, after hair removal treatment with IPL. The use of lasers and IPL is a common procedure used by dermatologists and even other professions for the treatment of cosmetically troubling skin conditions.

Multiple cutaneous angiomyxomas in a child.

Cutaneous myxomas are rare, benign, connective tissue tumors composed of stellate cells set in a loose mucoid stroma containing delicate reticulin fibers running in various directions. They are also called angiomyxomas to reinforce their vascular component. These lesions have been recognized as part of Carney complex.

Neurofibromatosis-Noonan syndrome: case report and clinicopathogenic review of the Neurofibromatosis-Noonan syndrome and RAS-MAPK pathway.

Neurofibromatosis-Noonan syndrome is an entity that combines both features of Noonan syndrome and Neurofibromatosis type 1. This phenotypic overlap can be explained by the involvement of the RAS-MAPK pathway (mitogen-activated protein kinase) in both disorders. We report the case of a 17-year-old boy with Neurofibromatosis 1 with Noonan-like features, who complained of the progressive appearance of blue-gray lesions on his back.
