Bullous hemorrhagic dermatosis (BHD) is a rare cutaneous manifestation characterized by tense hemorrhagic bullae that appear at sites distant from low molecular weight heparin (LMWH) injections, typically within seven days of exposure. As of March 2022, only 94 cases have been reported. It most commonly affects elderly males with predisposing factors for thromboembolism, such as carcinoma, and usually involves the extremities.

This case highlights the importance of maintaining a high index of suspicion for bullous hemorrhagic dermatosis (BHD) in patients receiving low molecular weight heparin, even beyond the typical 7-day window and in demographics not commonly affected. Early recognition and prompt discontinuation of the offending agent, as demonstrated in this atypical presentation involving a Filipino elderly woman with multiple comorbidities and no malignancy, can lead to favorable outcomes. Clinicians should be aware of this rare but reversible complication to avoid misdiagnosis and ensure appropriate management.

Hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP) is a rare autosomal dominant genetic disorder. It may also involve many other organ systems, leading to complications such as exocrine pancreatic insufficiency, liver dysfunction, lymphedema, and developmental delay. The FAM111B has been determined as the pathogenic gene associated with POIKTMP syndrome, whose protein product plays a critical role in regulating essential cellular processes including DNA repair and replication, cell cycle progression, apoptosis, nuclear transport, and telomere length maintenance. This article has provided a comprehensive review for the genetic basis of POIKTMP syndrome and its correlation with various phenotypes, which may offer insights for basic research and clinical diagnosis of this disease.

OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

OBJECTIVES: Papular dermatoses commonly affecting the female vulva, such as molluscum contagiosum, syringoma, lymphangioma, folliculitis, verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis, often present with similar clinical appearances and are frequently misdiagnosed. This study aims to explore the clinical diagnostic value of reflectance confocal microscopy (RCM) in differentiating these conditions. METHODS: A retrospective analysis was conducted on RCM imaging and histopathological findings from lesion sites in 172 female patients with vulval papular dermatoses. RCM characteristics confirmed by biopsy were summarized and diagnostic clues were explored. RESULTS: RCM diagnosis was consistent with histopathological diagnosis in 147 out of 172 cases (85.47%). Molluscum contagiosum, syringoma, lymphangioma, and folliculitis all exhibited cystic-like structures under RCM, differing in the location of the structures, wall characteristics, internal contents, and reflectivity. Verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis lacked such structures. Verruca vulgaris showed distinctive low-refractive vacuolated cells in the spinous layer; bowenoid papulosis exhibited mild cytologic atypia in the spinous layer; ectopic sebaceous glands were characterized by moderately to low-refractive, fish roe-like sebaceous lobules within the dermis. CONCLUSIONS RCM enables noninvasive, real-time, and dynamic visualization of key diagnostic and differential features of common vulvar papular dermatoses in women, offering high diagnostic value.

OBJECTIVES: Most dermatological conditions fall under visible skin diseases (VSDs), where lesions are exposed and readily seen, increasing patients' risk of experiencing external stigma from the public and specific professional groups (e.g., service providers). This stigma imposes psychological and social burdens that far exceed the psychological symptoms of the disease. To date, no systematic research has been conducted in China specifically on the external stigma associated with VSDs. Taking psoriasis, vitiligo, and acne as representative conditions, this study aims to explore the external stigma experienced by VSD patients across various social settings and to provide a scientific foundation for the development of measurement tools, quantitative research, and targeted interventions. METHODS: A purposive sample of 23 outpatients diagnosed with psoriasis, acne, or vitiligo was recruited from the Xiangya Hospital Dermatology Clinic of Central South University between December 2023 and July 2024. In-depth qualitative interviews were conducted. Data were analyzed using Mayring's qualitative content analysis and thematic analysis. Reporting followed the Consolidated Criteria for Reporting Qualitative Research guidelines. The interviews focused on the experience of external stigma across different social settings. RESULTS: Patients with VSDs reported experiencing external stigma in various contexts including family, community, recreational service venues, healthcare institutions, and others. The main motivation behind stigmatizing behaviors was disease avoidance (e.g., fear of contagion, aversion, social distancing). Stigmatization in school settings was also reported by patients with all 3 types of VSDs. Psoriasis patients reported stigma across all examined scenarios, while vitiligo and acne patients reported stigma in only some contexts. CONCLUSIONS Patients with VSDs experience significant external stigma, with psoriasis patients facing a higher burden compared to those with vitiligo or acne. The predominant stigma-driving factor is the public's desire to avoid disease, which underscores the need for public education to correct misconceptions about VSDs. External stigma from family, school, social networks, healthcare providers, and structural stigma should be the focus of policy and intervention efforts aimed at protecting the rights and well-being of patients with VSDs.

Currently, research on N⁶-methyladenine (m⁶A) is extensive in the field of oncology, while studies involving m⁶A and skin diseases remain relatively limited. Based on existing reports, we searched PubMed and Web of Science for literature related to m⁶A and dermatological conditions. Analysis of citation counts and journal impact factors revealed a significant upward trend in the volume of m⁶A-related research. Term frequency analysis of titles and abstracts indicated that studies mainly focus on skin tumors and inflammatory or immune-related skin diseases, particularly melanoma, psoriasis, and skin development. Transcriptomic data from the Gene Expression Omnibus (GEO) were analyzed, revealing differential expression of m⁶A-related genes in 4 types of skin tumors (including squamous cell carcinoma and basal cell carcinoma) as well as in inflammatory skin diseases such as psoriasis and atopic dermatitis, and potential mechanisms of action were also explored. Findings suggest that m⁶A modifications exhibit heterogeneity between neoplastic and non-neoplastic skin diseases. However, the regulatory mechanisms of m⁶A dynamic modifications on key genes involved in dermatological disorders remain unclear and warrant further investigation.

INTRODUCTION: The COVID-19 pandemic has changed care provision models, with a rapid increase in the adoption of telemedicine to reduce in-person visits. Although there are many benefits to teledermatology, there are also factors that hinder its widespread adoption. We aimed to examine patients' perceptions of teledermatology to identify the barriers to its adoption. METHODS: A prospective study was conducted from 15 June to 14 August 2020. Patients were invited to complete a questionnaire in an outpatient dermatology clinic via direct approach by clinical staff or posters posted at the door of consultation rooms. RESULTS: Out of 2,276 clinic attendances, 997 survey responses (43.8%) were collected over a 3-month period. When asked if they would change their subsequent visit to teledermatology, 294 (29.5%) patients were keen, 166 (16.6%) were unsure and 537 (53.9%) declined. Significant factors for declining teledermatology were lack of prior exposure to videoconferencing ( P < 0.01) and lower educational level ( P = 0.019). Patients also raised concerns regarding the ability of teledermatology to address medical concerns (32.1%) and indicated a preference for face-to-face consultation (29.7%). CONCLUSION Factors that influence patients' decision to adopt teledermatology, such as concerns about its ability to address medical issues, lack of IT literacy or experience in teleconferencing, are modifiable. Targeted strategies such as careful patient selection, a dedicated teleconsultation workflow, and the use of a novel 'teledermatology patient journey' (including a clinic walkthrough at the first visit) and an intuitive audio-enabled user interface, may improve patient perceptions and adoption of teleconsultation service.

Stiff skin syndrome is a very rare non-inflammatory reactive skin disease, characterized by skin sclerosis and limited joint mobility. The paper reports one case of child with stiff skin syndrome and treated with combined therapy of acupuncture and cupping. Acupuncture was used at the lateral line 1 of vertex (MS8) on the right side, Jiaji (EX-B2) of L₂ to L₄, Huantiao (GB30), ashi point, Juliao (GB29), Fengshi (GB31), Weizhong (BL40), and etc. on the left side. After deqi, the electrodes of KWD-808Ⅰimpulse electronic therapeutic device were attached to Jiaji (EX-B2) of L₄ and Huantiao (GB30), Fengshi (GB31) and Yanglingquan (GB34) on the left side respectively, at disperse-dense wave, a frequency of 2 Hz/100 Hz, and a current of 2 mA. The needles were retained for 20 min. Acupuncture was operated once every 2 days, 3 interventions a week. When acupuncture was completed in each intervention, moving cupping was followed till the skin turned to be red, along the distribution of the governor vessel, foot-shaoyang gallbladder meridian and foot-taiyang bladder meridian on the left side, of the lumbar region and leg. Moving cupping was delivered once every 2 days, 3 times a week. Once a week, after moving cupping, the cups were retained on the areas with skin stiffness for 8 min to 10 min. One course of the combined therapy of acupuncture and cupping was composed of 6 treatments. After 2 courses of treatment, the skin stiffness on the left buttock region and the lateral side of the lower limb was ameliorated, the swelling on the left lower limb relieved and the walking improved; and the patient could walk continuously for 2 000 m. The combined therapy of acupuncture and cupping provides a new idea for the clinical treatment of stiff skin syndrome.

The paper reports one case of primary cutaneous amyloidosis (PCA) treated by tapping with plum-blossom needle combined with sulfur ointment and local irradiation. PCA in this case was manifested as generalized erythema, papules, plaques, lichenification, and severe pruritus. In treatment, tapping with plum-blossom needle was delivered at typical lesions to induce local congestion, redness, and minimal bleeding. After cleaned with sterile gauze for 10 s, 25% sulfur ointment was evenly applied, followed by local irradiation with a TDP lamp for 15 min. This session was repeated twice a week. In 1 month of treatment, the lesions turned flat and the skin was soft as the normal, with pigmentation and mild pruritus left. In 3 months of follow-up, no papules recurred, and mild pruritus presented occasionally.
