Integrative Approaches for the Diagnosis and Management of Erosive Oral Lichen Planus.

Erosive oral lichen planus (EOLP) represents a significant challenge in dental and medical management due to its chronic inflammatory nature, painful symptoms, and impact on quality of life. This study aims to evaluate the current diagnostic approach with novel non-invasive techniques, such as dermoscopy, and also the landscape of treatment options for EOLP, focusing on its efficacy, safety, and the challenges that it present in clinical practice. Through a comprehensive literature review, we explored the use of topical corticosteroids, systemic immunosuppressants, biologics, and Janus kinase (JAK) inhibitors in treating EOLP, alongside examining patient compliance, psychological impacts, and the risk of adverse effects and recurrence. Our findings reveal that while topical corticosteroids are the cornerstone of EOLP treatment, offering symptomatic relief, their long-term use is limited by side effects and tolerance development. Systemic therapies and biologics provide alternatives for refractory cases but necessitate careful adverse effect monitoring. JAK inhibitors show promise as an innovative treatment avenue but require more evidence on long-term safety and efficacy. This study highlights the necessity of personalized treatment approaches due to the variable disease course and response to treatment, underscoring the importance of a multidisciplinary strategy in managing EOLP. The complexity of EOLP treatment, compounded by its psychological and quality of life impacts, demands ongoing research into targeted therapies, the establishment of standardized treatment protocols, and the development of effective outcome measures to improve patient care and treatment outcomes.

Differences and Similarities in Epidemiology and Risk Factors for Cutaneous and Uveal Melanoma.

Both cutaneous melanoma (CM) and uveal melanoma (UM) represent important causes of morbidity and mortality. In this review, we evaluate the available knowledge on the differences and similarities between cutaneous melanoma and uveal melanoma, focusing on the epidemiological aspects and risk factors. Uveal melanoma is a rare condition but is the most prevalent primary intra-ocular malignant tumor in adults. Cutaneous melanoma, on the other hand, is significantly more common. While the frequency of cutaneous melanoma has increased in the last decades worldwide, the incidence of uveal melanoma has remained stable. Although both tumors arise from melanocytes, they are very distinct entities biologically, with complex and varied etiologies. Both conditions are encountered more frequently by individuals with a fair phenotype. ultraviolet-radiation is an important, well-documented risk factor for the development of CM, but has shown not to be of specific risk in UM. Although cutaneous and ocular melanomas seem to be inherited independently, there are reported cases of concomitant primary tumors in the same patient.

Drug-induced Rowell syndrome, a rare and difficult to manage disease: A case report.

Rowell syndrome is defined as the association between lupus erythematosus, erythema multiforme-like lesions and characteristic immunological changes including positive tests for rheumatoid factor, speckled antinuclear antibody, positive anti-Ro or anti-La antibodies. The present report presents the case of a 45-year-old female patient who was previously diagnosed in January 2010 with terbinafine-induced subacute cutaneous lupus erythematosus and was admitted for a skin eruption consisting of erythematous-papular erythema multiforme-like lesions, primarily on the trunk and limbs. The associated symptoms consisted of fatigability, myalgia and gonalgia. In October 2015, the illness reoccurred ~1 week after the initiation of Helicobacter pylori eradication treatment. Anti-Ro antibodies, rheumatoid factor and antinuclear antibody tests were positive. Given the patient's medical history, clinical manifestations, and laboratory, histopathological and immunofluorescence microscopy findings, a diagnosis of Rowell syndrome was made. Systemic corticosteroids (methylprednisolone; 0.5 mg/kg/day) and immunomodulatory therapy (azathioprine; 50 mg/day) were administered with the associated medication (omeprazole, 20 mg/day; KCl, 1 g/day) and topical dermocorticoids (fluticasone propionate 0.05% cream; 1 application/day), with a favorable outcome. The major diagnostic criteria for Rowell syndrome are the presence of lupus erythematosus (acute, subacute or systemic), erythema multiforme-like lesions and positive testing for antinuclear antibodies. The minor diagnostic criteria for Rowell syndrome are chilblains, the presence of anti-Ro antibodies and positive testing for rheumatoid factor. A diagnosis of Rowell syndrome is made if the patient exhibits all major criteria and at least one minor criterion. The present case met all diagnostic criteria, excluding the presence of chilblains. Notably, in this case there was a co-occurrence of subacute lupus erythematosus and Rowell syndrome lesions, which was drug-induced.

Assessment of dermal papillary and microvascular parameters in psoriasis vulgaris using in vivo reflectance confocal microscopy.

In vivo reflectance confocal microscopy (RCM) is a modern, non-invasive imaging technique, which allows for real-time examination of the upper layers of the skin at a resolution similar to that of classic microscopy. In addition, it has the advantage of real-time evaluation of blood flow and dynamic monitoring of cutaneous changes while preserving tissue integrity. The present study reported on the in vivo RCM technique as an objective method for the noninvasive assessment of psoriasis vulgaris that is potentially applicable in clinical studies and in monitoring the evolution of lesions under treatment. In psoriasis lesions, RCM virtual horizontal sections at the level of the dermo-epidermal junction featured numerous and prominent dermal papillae that were not surrounded by bright rings of basal cells. Micromorphological examination of the lesions using this technique revealed that mean values of the section area, the perimeter and the Feret's diameter of the dermal papillae were significantly higher in psoriatic lesions than in normal skin. An increased number of capillary vessels per lesional dermal papilla as compared to healthy skin was observed. Furthermore, micromorphological parameters of dermal capillaries were increased in psoriatic skin. These observations point to the utility of in vivo RCM as a promising technique for the non-invasive diagnosis of psoriasis vulgaris, for monitoring the evolution of lesions at a micromorphological level under various treatments and for gaining a better understanding of the pathophysiological processes that occur in the evolution of this disease.
