Clinical assessment of the use of topical liquid diclofenac following laser microporation of cutaneous neurofibromas in individuals with neurofibromatosis type 1.

Background: Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder with a prevalence of 1:3000 births and a wide variety of clinical manifestations. Cutaneous neurofibromas (cNF) are among the most common visible manifestations of NF1 and present a major clinical burden for patients. NF1 patients with cNF often report decreased quality of life, emotional well-being and physical comfort.

Prevalence and clinicopathological characteristics of lipomatous neurofibromas in neurofibromatosis 1: An investigation of 229 cutaneous neurofibromas and a systematic review of the literature.

Background: Lipomatous neurofibroma (Lnf) is a histopathological variant with adipocytes noted among cells of cutaneous neurofibromas. We aimed to investigate the prevalence and clinicopathological features of Lnfs of neurofibromatosis 1 (NF1)-associated cutaneous neurofibromas and to review the literature systematically. We also evaluated the expression of leptin (a hormone involved in lipid metabolism) in neurofibromas to better understand the pathogenesis of Lnfs.
