Abstract
An 11-year-old female with neurofibromatosis type 1 (NF-1) and history of optic glioma presented with a progressive cutaneous plexiform neurofibroma of the breast. The lesion was treated with topical application of a mitogen-activated protein kinase inhibitor, trametinib, resulting in stable, non-progression cutaneous plexiform neurofibroma for greater than 2 years. This case demonstrates the potential application of topical trametinib for NF1-associated superficial cutaneous plexiform neurofibroma without the toxicities associated with systemic treatment.

Abstract
The research of the last two decades has defined a crucial role of cellular senescence in both the physiology and pathology of skin, and senescent cells have been detected in conditions including development, regeneration, aging, and disease. The pathophysiology of cellular senescence in skin is complex as the phenotype of senescence pertains to several different cell types including fibroblasts, keratinocytes and melanocytes, among others. Paradoxically, the transient presence of senescent cells is believed to be beneficial in the context of development and wound healing, while the chronic presence of senescent cells is detrimental in the context of aging, diseases, and chronic wounds, which afflict predominantly the elderly. Identifying strategies to prevent senescence induction or reduce senescent burden in the skin could broadly benefit the aging population. Senolytics, drugs known to specifically eliminate senescent cells while preserving non-senescent cells, are being intensively studied for use in the clinical setting. Here, we review recent research on skin senescence, on the methods for the detection of senescent cells and describe promises and challenges related to the application of senolytic drugs. This article is part of the Special Issue - Senolytics - Edited by Joao Passos and Diana Jurk.
