It inhibits the MAPK pathway by binding to BRAF V600E, resulting in an antitumor effect in melanoma. 2 The most frequent adverse events are cutaneous 1-3. The proliferation of keratinocytes is usually common when using Vemurafenib, ranging from benign, verrucous lesions to malignant, such as SCC. This appears early, usually between the 7th and 8th weeks of treatment and seems to be caused by the paradoxical activation of MAPK by Vemurafenib in cells with wild BRAF and RAS mutation through CRAF dimers. 2,3,10 It is believed that keratinocytes from sun-exposed areas in elderly patients with fair skin have RAS mutations and their activation can cause skin tumors. 1,2,10 Rashes are common and can be keratosis pilaris-like or maculopapular; they usually spare the face. 3,10 They may coalesce, with the appearance of harmful erythema. Normally, they are not severe enough to require discontinuation of treatment. 3,10 Photosensitivity during treatment with Vemurafenib occurs after sun exposure. UVA radiation plays an important role in pathogenesis and it permeates glass. Daily use of sunscreen (minimum SPF 30 and broad UVA protection), appropriate clothing and accessories and 100% UVA and UVB protective films around the windows of the car, house or at work, are recommended. 3,10 BRAF mutation is usually a common occurrence in melanocytic nevi. 4 It is presumed that Vemurafenib action in these cases induces involution, whereas wild BRAF nevi would undergo paradoxical activation of MAPK pathway and atypia. 4,5 A second primary melanoma caused by Vemurafenib has been reported. 5 BRAF V600E metastases respond to Vemurafenib, whereas wild BRAF melanomas would be activated. 5 Digital dermoscopy performed before therapy with a monthly follow-up enables identification of suspicious lesions, while confocal microscopy can be complementary. 5 Skin biopsy is useful for diagnostic confirmation. Panniculitis associated with Vemurafenib treatment has been described. 6,7 It may appear along with fever, arthritis and arthralgia. In general, biopsies reveal the presence of predominantly lobular neutrophilic panniculitis. 7 It can be treated with dental corticosteroids, anti-inflammatory and discontinuation of Vemurafenib, when it’s as well symptomatic. Expectant follow-up can be an choice in milder instances. 6 Vemurafenib could cause level of sensitivity in the irradiated pores and skin and can become put into the set of medicines that trigger rays recall dermatitis. Topical ointment corticosteroids reduce symptoms. 8 Camidge et al. recommended that pores and skin reactions due to medicines given up to seven days after radiotherapy is highly recommended radiosensitization reactions, than radiation recall rather. 9 Dermatologists and oncologists should be aware of pores and skin reactions due to plan and Vemurafenib routine appointments during therapy. We suggest dermatologic evaluation with dermoscopy prior to the begin of treatment, after four weeks and every eight weeks, with confocal microscopy together, for better evaluation of the lesions, whenever you can.
