Generalized pustular psoriasis is defined as a primary, sterile, macroscopically visible pustular eruption on non-acral skin, which can occur with or without systemic inflammation and/or psoriasis vulgaris, and can either be relapsing or be persistent, according to the European Rare and Severe Psoriasis Expert Network. The treatment of generalized pustular psoriasis may be challenging. We describe a 48-year-old woman with a 15-year history of severe generalized pustular psoriasis and plaque psoriasis resistant to multiple courses of treatments with conventional and biological agents who had a rapid, complete and durable (up to 12 months) clinical remission with spesolimab, an anti-interleukin-36 receptor antagonist monoclonal antibody recently approved for the treatment of generalized pustular psoriasis flares.

Background/Objectives: Melanoma is an aggressive cutaneous malignancy with a rising incidence. While most cases are sporadic, 5–10% are hereditary, especially in patients with multiple or familial melanomas. The aim of this study is to explore the epidemiological, clinical, histological, and genetic features of this class of patients to identify risk factors for better management and surveillance. Methods: Between 2021 and 2024, patients with multiple melanomas or a familial history of melanoma were recruited. Collected data included demographic, clinic-pathologic features, and genetic analyses. Results: Patients >60 years had a higher prevalence of multiple melanomas (>50%, p = 0.0002), while familial melanoma was more common in those <40 years (54.3%). UV exposure increased with age, while sunscreen use decreased (p = 0.0004). Younger patients showed the highest nevi counts (mean: 139.6) and density (p < 0.0001). Dermatologists more frequently detected subsequent melanomas in older patients (>60 years) (p = 0.001). Genetic testing and melanoma subtypes showed no significant age-related differences. Conclusions: melanoma can develop at any age, and early detection through regular screening is crucial. Older patients (>60 years) have a higher prevalence of multiple melanomas, influenced by UV exposure and genetics. Indeed, in our cohort, a history of sun exposure, sunburns, and tanning bed use emerged as key risk factors, particularly among older individuals. Genetic testing showed a 4.3% rate of pathogenic/likely pathogenic variants, mainly in CDKN2A. Family history and nevus burden are significant risk factors, highlighting the need for targeted surveillance in high-risk populations.

Midline Anterior Neck Inclusion Cysts (MANICs) are rare congenital anomalies caused by improper embryonic fusion. These superficial benign lesions typically appear yellowish and cystic without deeper anatomic connections. We describe an 11-month-old boy with a stable, asymptomatic, yellow, elastic cystic lesion on the midline of the anterior neck, measuring 4 mm and present since shortly after birth. Clinical, dermoscopic, and ultrasound evaluations confirmed the diagnosis of MANIC. Over six months of observation, the lesion remained stable without growth, infection, or symptoms. MANICs are benign epidermoid cysts with minimal risk of complications that are often mistaken for thyroglossal duct cysts, dermoid cysts, or other congenital anomalies. Unlike thyroglossal duct cysts, they do not move during swallowing or tongue protrusion. Management is usually conservative, with surgery reserved for symptomatic or cosmetically significant cases. This case highlights the importance of parental reassurance and avoiding unnecessary intervention for asymptomatic lesions. Recognition of MANICs is essential for dermatologists and pediatricians evaluating midline neck lesions. A conservative approach with regular monitoring ensures optimal care while minimizing interventions. Further research may clarify the pathogenesis and long-term outcomes of these rare lesions.

Green pit vipers of the genus Trimeresurus are among the leading causes of snakebite envenomation across tropical and subtropical Asia, yet their clinical phenotype has been less systematically characterized than that of other medically important Asian viperids. This comprehensive review synthesizes the published clinical literature on human Trimeresurus envenomation, drawing on 70 clinical reports encompassing 4720 reported patient episodes, and integrates these data with current taxonomic and venomic evidence. Envenomations cluster in East, Southeast, and South Asia. The single most important limitation of this literature is the unreliability of species attribution: 55% of reported cases are attributed only at genus level or derive from cohorts in which two or more Trimeresurus species are reported together and cannot be separated, a figure consistent with the 56% of snakebites left unidentified in a recent 40,817-patient Chinese survey. Bites involve the extremities almost exclusively, with a predominance of the lower limb (55% versus 45%). The clinical picture is dominated by local effects (i.e., extensive edema and pain in the large majority of patients, secondary infection in approximately one in six, and cutaneous necrosis in approximately one in thirty) and by systemic hemotoxicity driven by venom-induced consumptive coagulopathy. Renal involvement is uncommon, in contrast to Daboia russelii envenomation, and severe neurotoxicity is exceptional. Documented mortality in the reviewed hospital-based literature is low (two deaths among 3387 patients in reports documenting outcome, <0.1%) but is not zero, and hospital-based series cannot capture pre-hospital deaths. Management centers on conservative wound care, serial coagulation monitoring, and selective antivenom administration; routine fasciotomy is not justified without objective evidence of compartment syndrome. Reliable species identification, standardized clinical reporting, and long-term functional follow-up remain the principal unmet needs.
