These mutations result in dysfunction of an endoplasmic reticulum Ca<span class="elsevierStyleSup">2+</span> ATPase (SERCA2), thus interfering in the signaling of intracellular calcium. Consequently, there is loss of supra-basal cell adhesion (acantholysis) and induction of apoptosis (dyskeratosis).</p><p id="par0030" class="elsevierStylePara elsevierViewall">From a clinical point of view, classic Darier disease is characterized by the presence of crusted greasy keratotic papules and plaques, located predominantly in seborrheic areas. Additional findings include palmoplantar papules, whitish papules on the oral mucosa and variable nail changes, including V-shaped notching and alternating white and red longitudinal streaks, which is considered pathognomonic.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">1</span></a> Environmental factors, including heat, friction, sweating and UV light can induce flares, and some medications are also known to cause exacerbations, namely lithium.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">2</span></a> Darier disease follows a chronic course with oscillations in disease severity and secondary bacterial and viral infections are frequent complications.</p><p id="par0035" class="elsevierStylePara elsevierViewall">In addition to the more classic presentation, two types of segmental Darier disease have been described, both with lesions distributed along the lines of Blaschko. The most common subtype is type 1, which is the result of a post-zygotic mutation in the <span class="elsevierStyleItalic">ATP2A2</span> gene during embryogenesis, thus prompting cutaneous mosaic involvement. In type 1 segmental disease, the age of onset, severity and histological findings are similar to the generalized Darier form. Type 2 mosaicism is more severe and less frequent. These patients present with generalized Darier disease as well as additional linear lesions, with increased severity.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">3</span></a> Type 2 segmental disease occurs when patients carrying a heterozygous germline mutation have an additional postzygotic inactivating mutation in the other allele of the same gene, causing loss of heterozygosity. The histological findings described in this patient evoke the diagnosis of Darier's Disease; in light of the clinical picture described, this case corresponds to type 1 segmental disease.</p><p id="par0040" class="elsevierStylePara elsevierViewall">The therapeutic approach to Darier disease is often difficult and challenging. General measures including avoidance of heat and minimization of friction are helpful.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">2</span></a> In addition, corticosteroids can be used to reduce inflammation and topical antimicrobial washes may help decrease the risk of superimposed infection. Systemic retinoids and low-dose naltrexone have been used in some cases with good results.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">2</span></a> Surgical approach is an option in severe refractory cases.
