Acquired diffuse slate-grey facial dyspigmentation due to henna: an unrecognized cause of pigment contact dermatitis in Korean patients.

Henna is a vegetable hair dye that can be used by individuals who are sensitized to oxidative dyes due to low allergenicity. The reported incidence of slate-grey facial dyspigmentation following the use of henna hair dye is extremely rare. This study aimed to identify the clinical, dermoscopic, and histopathological features of slate-grey facial dyspigmentation following the use of henna hair dye in Korean patients.

Cutaneous comorbidities in patients with multiple myeloma: A 10-year retrospective cohort study from a Korean population.

Multiple myeloma (MM) is a common hematologic malignancy characterized by the presence of the clonal proliferation of tumor cells. Studies on cutaneous comorbidities in Asian patients with MM have yet to be conducted.This study aimed to analyze the prevalences, characteristics, overall survivals, and risk factors of various cutaneous comorbidities in patients with MM.

Effect of ingenol mebutate on actinic keratosis in a Korean population: A prospective clinical, dermoscopic and histopathological study from a single center.

Actinic keratosis (AK) is an in situ squamous cell carcinoma which is mostly found on sun-damaged skin, and it is prevalent among Caucasians. However, there is a lack of research on evaluating the treatment efficacy of ingenol mebutate (IM) on AK in Asians. This study was intended to analyze the treatment outcomes of IM on AK in Korean patients with regards to clinical, dermoscopic and histopathological aspects.

Prevalence and clinicopathologic characteristics of multiple myeloma with cutaneous involvement: A case series from Korea.

Background: Multiple myeloma (MM) is a plasma cell dyscrasia characterized by the presence of a clonal proliferation of tumor cells. Cutaneous involvement of MM is very rare and remains poorly understood.

Objective: The aim of this study was to examine the clinical and histopathologic characteristics of cutaneous involvement in MM and identify factors associated with overall survival of MM with cutaneous involvement.

Silicone Facial Prosthesis: A Preliminary Report on Silicone Adhesion to Magnet.

Although a silicone facial prosthesis has many advantages, silicone's limited cementation with resin or metal has caused many maxillofacial reconstructive surgeons and prosthodontists concern regarding the use of silicone-based facial prostheses. This study demonstrates 1 representative silicone facial prosthesis patient with magnet cementation to silicone using plastic clay, which will be applied to various maxillofacial prosthesis strategies in the near future.

Molecular Mechanisms of Cutaneous Inflammatory Disorder: Atopic Dermatitis.

Atopic dermatitis (AD) is a multifactorial inflammatory skin disease resulting from interactions between genetic susceptibility and environmental factors. The pathogenesis of AD is poorly understood, and the treatment of recalcitrant AD is still challenging. There is accumulating evidence for new gene polymorphisms related to the epidermal barrier function and innate and adaptive immunity in patients with AD.
