Apalutamide is an antiandrogen used to treat prostate cancer. Although it sometimes induces mild cutaneous adverse events and occasionally severe ones, clinical differences between severe and mild cases remain unclear. To assess the risks in patients experiencing apalutamide-related cutaneous adverse events (ARCAEs), we aimed to characterize severe and mild ARCAEs in terms of onset time and lymphocyte transformation test (LTT) for apalutamide. We reviewed 41 ARCAE cases: 24 from our institute and 17 from the literature, comprising (i) eight severe cases including six with toxic epidermal necrolysis, one with acute generalized exanthematous pustulosis, and one with drug reaction with eosinophilia and systemic symptoms, and (ii) 33 mild cases...

Basal cell carcinoma accounts for 75% of skin cancers worldwide and is the most common malignancy in Caucasians. Since chronic ultraviolet exposure is the major risk factor for its development, sun-exposed areas such as the face are frequently affected. The gold-standard treatment is surgical excision. Radiotherapy may be considered in selected cases such as unresectable primary tumors. In some patients, when the risk of a significant functional/cosmetic deficit advises against both surgery and radiotherapy, target therapy (hedgehog pathway inhibitors) can be administered alone or in a neoadjuvant setting, to reduce the tumor size and make it eligible for surgery...

Of those patients diagnosed with generalized pustular psoriasis (GPP) in Japan, approximately 30% have a prior psoriasis vulgaris (PsV) diagnosis. Therefore, understanding factors associated with a GPP diagnosis is essential for early diagnosis of GPP in patients with PsV. This retrospective cohort study was conducted to identify associated factors for GPP diagnosis in patients with PsV. Eligible patients with two confirmed diagnoses of PsV with/without a confirmed GPP diagnosis (International Classification of Disease 10th revision codes L40...

Neuronal intranuclear inclusion disease (NIID) is a rare neurodegenerative disease with variable clinical phenotypes. There is a considerable delay in the definite diagnosis, which primarily depends on postmortem brain pathological examination. Although CGG repeat expansion in the 5'-untranslated region of NOTCH2NLC has been identified as a disease-associated variant, the pathological diagnosis is still required in certain NIID cases. Intranuclear inclusions found in the skin tissue of patients with NIID dramatically increased its early detection rate...

An 85-year-old woman with no history of herpes zoster (HZ) presented with a primary lesion of erythema and blistering on her left thigh and a secondary similar lesion on her right chest which had appeared at 4 and 3 days before presentation, respectively. Tzanck smears for both lesions were positive, revealing multinucleated giant cells. Immunochromatography to detect varicella-zoster virus (VZV) antigen (DermaQuick®VZV) showed positive on the left thigh at initial onset but negative on the right chest at subsequent onset...

To date, 10 types of human papillomavirus have been identified that cause flat warts, including human papillomavirus type 3, which belongs to species group 2 of the genus alpha papillomavirus. Among these 10 types, human papillomavirus type 94 is most closely related to human papillomavirus type 10, sharing 86% homology. In this study, we conducted polymerase chain reaction analysis with sequencing on samples obtained from cutaneous lesions located on the face and lower legs of an individual, revealing the presence of human papillomavirus type 94...

Psoriasis is a chronic, refractory inflammatory skin disease, with a high prevalence of psychiatric comorbidities, including depression, anxiety, and even suicidality, which may in turn initiate or exacerbate skin inflammation. However, the causal relationships between these comorbidities remain unclear. To investigate the cause-effect relationships between psoriasis and mental disorders including depression, anxiety, and suicidality, we conducted a bidirectional two-sample Mendelian randomization (MR) study utilizing summary statistics from the most comprehensive genome-wide association studies of psoriasis (n = 306 123), broad depression (n = 500 199), major depressive disorder (n = 173 005), anxiety (n = 17 310), and suicide attempts (n = 50 264)...

Epidermolysis bullosa (EB) is a group of inherited blistering disorders that primarily affect the skin and mucous membranes of the digestive tract, which can lead to poor nutritional status. Dietary supplements and nutritional support methods, such as nasogastric tubes and gastrostomy, have been employed to improve the nutritional status of patients with EB; however, few foods are suitable for enjoyable eating with family and friends. Here, we introduce a nutritionally balanced, melt-in-the-mouth chocolate called andew, which was specifically designed for patients with EB...
