Abstract Objectives To estimate the economic costs of oral lichen planus (OLP) through a multicenter university hospital–based outpatient study conducted in Italy and Finland. Materials and methods A multicenter retrospective study was conducted on patients affected by OLP to evaluate the economic cost of managing the disease. Direct costs concerning diagnostic procedures, therapeutic management, and follow-up visits were obtained from clinical records. Statistics was performed with IBM SPSS Statistics. Results One hundred and eight patients with a confirmed diagnosis of OLP (81 women and 27 men), 58 Italians and 50 Finnish, were enrolled in this study. The mean annual cost was 1087.2 euros per patient. The mean annual cost was higher in Finnish than in Italian cohort (1558.7 euros vs. 680.7 euros—p < 0.05). Within the Italian cohort, the local immunosuppressive therapy group and atrophic and erosive OLP type had a higher cost (p < 0.05). Within the Finnish cohort, the local immunosuppressive therapy group had a higher cost (p < 0.05). Conclusions OLP-related costs are very similar to other chronic oral disorders (i.e., periodontitis) with differences between investigated countries. Moreover, patients with more severe clinical features, who need immunosuppressive therapy, are facing more expensive costs. Clinical relevance. In this multicenter cost of illness study, we estimated the direct health care costs of OLP and we found that patients with more severe clinical features, who therefore need symptomatic therapy, are facing more expensive costs.

Cutaneous involvement of chronic graft-versus-host disease (cGVHD) has a wide range of manifestations including a lichenoid form with a currently assumed mixed Th1/Th17 signature and a sclerotic form with Th1 signature. Despite substantial heterogeneity of innate and adaptive immune cells recruited to the skin and of the different clinical manifestations, treatment depends mainly on the severity of the skin involvement, and relies on systemic, high-dose glucocorticoids alone or in combination with a calcineurin inhibitor. We performed the first study using RNAseq to profile and compare the transcriptome of lichen planus cGVHD (n=8), morphea cGVHD (n=5), and healthy controls (n=6). Our findings revealed shared and unique inflammatory pathways to each cGVHD subtype that are both pathogenic and targetable. In particular, the deregulation of IFN signaling pathway was strongly associated with cutaneous cGVHD, whereas the triggering receptor expressed on myeloid cells-1 (TREM-1) pathway was found to be specific of lichen planus and likely contributes to its pathogenesis. The results were confirmed at a protein level by performing immunohistochemistry staining and at a transcriptomic level using Real-Time quantitative PCR.

Sir, Porokeratosis is a group of cutaneous diseases presented by epidermal keratinization [1]. Herein, we report the case of a patient with porokeratosis who responded well to carbon dioxide (CO2) laser therapy. A 22-year-old Vietnamese male visited our department with an asymptomatic plaque on the penis present for three months. He denied a family history of similar lesions. A cutaneous examination of the penis revealed an annular, well-circumscribed plaque with slightly raised borders with scales (Fig. 1a). Other mucocutaneous lesions were absent. Fungal microscopy, a rapid plasma reagin (RPR) test, and a Treponema pallidum hemagglutination (TPHA) test were negative. Histological findings revealed a hyperkeratotic lesion with a discrete parakeratotic column. There was the presence of a cornoid lamella, which was a parakeratotic column overlying a small vertical zone of dyskeratotic and vacuolated cells within the epidermis (Fig. 2a). There was also a focal loss of the granular layer. A mild lymphocytic infiltrate could be seen around an increased number of capillaries in the underlying dermis (Fig. 2b). CO2 laser removal was performed. There was no recurrence after a twelve-month follow-up (Fig. 1b). However, a hypopigmented scar was seen. Porokeratosis is an uncommon disorder of keratinization with clinical variants, such as classical porokeratosis of Mibelli, disseminated superficial actinic porokeratosis, linear porokeratosis, and porokeratosis palmaris et plantaris disseminata [2]. Porokeratosis involving the genital areas and other adjacent sites is rare [2]. Genital porokeratosis was first described by Helfman in 1985 [3]. More than 69 cases have been reported in the literature [1]. The pathophysiology of genital porokeratosis remains unknown. It has been supposed that porokeratosis is linked to repeated minor frictional trauma. A benign lesion may transform into squamous cell carcinoma or basal cell carcinoma [4]. However, no malignant transformation of genital porokeratosis has been noted in the literature. Genital porokeratosis manifests itself clinically as classic or plaque-type porokeratosis of Mibelli [2]. Histological findings revealed a cornoid lamella with the absence of a granular layer and dyskeratotic cells in the upper spinous zone [2]. Our case may mimic some annular lesions, such as secondary syphilis, fungal infection, and annular lichen planus. Because a fungal examination and syphilis serology were negative, we could exclude fungal infection and annular secondary syphilis. The distinctive histology of porokeratosis such as a cornoid lamella with a decreased granular layer may help to differentiate between porokeratosis and annular lichen planus [4]. Numerous therapeutic methods of treatment exist, including surgical excision, CO2 laser, cryotherapy, topical retinoids, 5% 5-fluorouracil, vitamin D3 analogs, imiquimod cream, and 3% diclofenac gel [2,5].
