Target therapies are currently a therapeutic option increasingly used for the management of patients with metastatic melanoma. However, there are multiple adverse pharmacological effects associated with their use that have been described. Cutaneous adverse reactions are the most frequent. We report the case of a 55-year-old man with a diagnosis of stage IV BRAFV600E-mutated metastatic cutaneous melanoma undergoing treatment with dabrafenib/trametinib, who consulted due to the development of erythematous nodular lesions in the upper and lower limbs associated with febrile sensation during the course of treatment. Infection was ruled out and a biopsy of the skin lesions was done, which provided the histopathological confirmation of a predominantly septal, granulomatous with leukocytoclastic vasculitis, mixed panniculitis. Panniculitis associated with this therapy has been described in the literature and has been considered an immune-mediated pharmacological adverse effect. It is considered to be related to a better prognosis in the treatment of metastatic melanoma. Consequently, as shown in this case report, target therapy should not be discontinued and symptomatic medication should be given to alleviate patient discomfort. The dermatologist should know and properly interpret this adverse effect and prescribe the most appropriate management for the patient.
Las terapias target constituyen hoy en día una alternativa terapéutica cada vez más utilizada para el manejo de pacientes con melanoma metastásico. Sin embargo, se han descrito múltiples efectos farmacológicos adversos asociados a su uso, siendo los cutáneos los de mayor prevalencia. Se presenta el caso de un hombre de 55 años con diagnóstico de melanoma cutáneo metastásico etapa IV, BRAFV600E mutado, en tratamiento con dabrafenib/trametinib que consultó por desarrollo de lesiones nodulares eritematosas sensibles en extremidades superiores e inferiores, asociadas a sensación febril durante el curso del tratamiento. Se descartó alguna infección sobreagregada. Se realizó una biopsia de las lesiones cutáneas, con confirmación diagnóstica histopatológica de una paniculitis mixta de predominio septal, granulomatosa y con vasculitis leucocitoclástica. La paniculitis asociada a esta terapia ha sido descrita en la literatura y se ha considerado un efecto farmacológico inmunomediado adverso, relacionándose a un mejor pronóstico para el melanoma metastásico en tratamiento. Por lo tanto, así como en el caso presentado, se evita la suspensión del fármaco y se asocia terapia sintomática en caso de mayores molestias del paciente. Es de alta relevancia para el dermatólogo conocer e interpretar adecuadamente este efecto adverso farmacológico, y así indicar el manejo más adecuado para el paciente.

Many patients presently have access to their pathologic test result reports via online patient portals, yet little is known about pathologists\' perspective on this topic.
To examine dermatopathologists\' experience and perceptions of patient online access to pathology reports.
A survey of 160 dermatopathologists currently practicing in the United States who are board certified and/or fellowship trained in dermatopathology was conducted between July 15, 2018, and September 23, 2019. Those who reported interpreting skin biopsies of melanocytic lesions within the previous year and expected to continue interpreting them for the next 2 years were included.
Dermatopathologists\' demographic and clinical characteristics, experiences with patient online access to pathologic test result reports, potential behaviors and reactions to patient online access to those reports, and effects on patients who read their pathologic test result reports online.
Of the 160 participating dermatopathologists from the 226 eligible for participation (71% response rate), 107 were men (67%); mean (SD) age was 49 (9.7) years (range, 34-77 years). Ninety-one participants (57%) reported that patients have contacted them directly about pathologic test reports they had written. Some participants noted that they would decrease their use of abbreviations and/or specialized terminology (57 [36%]), change the way they describe lesions suspicious for cancer (29 [18%]), and need specialized training in communicating with patients (39 [24%]) if patients were reading their reports. Most respondents perceived that patient understanding would increase (97 [61%]) and the quality of patient-physician communication would increase (98 [61%]) owing to the availability of online reports. Slightly higher proportions perceived increased patient worry (114 [71%]) and confusion (116 [73%]). However, on balance, most participants (114 [71%]) agreed that making pathologic test result reports available to patients online is a good idea.
Dermatopathologists in this survey study perceived both positive and negative consequences of patient online access to pathologic test result reports written by the respondents. Most participants believe that making pathologic test result reports available to patients online is a good idea; however, they also report concerns about patient worry and confusion increasing as a result. Further research regarding best practices and the effect on both patients and clinicians is warranted.

BACKGROUND: Most laser-induced retinal injuries are caused by accidental laser discharge during the preparation of laser devices without protective goggles, laser injury during the cosmetic procedure in a dermatologist, is very rare, with no prior case reports.
METHODS: A 55-year-old Asian male dermatologist visited our hospital with a 2-week history of visual disturbance in his right eye. He had experienced sudden central scotoma in the right eye while using a Q-switched Nd:YAG laser (1064 nm, 2 J/cm, 6-mm spot size, 750 ps) 2 to 3 cm from the target without proper eye protection. He had applied a glass slide firmly onto the treatment area prior to commencing the procedure. The choroidal neovascularization (CNV) was detected via optical coherence tomography angiography (OCTA) 2 weeks after the laser injury.
METHODS: Foveal CNV secondary to laser energy reflected from the glass slide.
METHODS: Intravitreal bevacizumab (1.25 mg/0.05 mL) injection was performed.
RESULTS: Regression of CNV was observed.
CONCLUSIONS: Retinal injury can occur not only by direct laser beam exposure but also by way of a beam reflected from a glass slide. Operators should always use laser safety eyewear during cosmetic procedures involving laser devices, so as to prevent the occurrence of ocular complications. Thorough short-term follow-up with OCTA is recommended for the prompt detection of CNV in cases of retinal laser injury.

Perceptions of the clinical management of delusional infestation (DI) were compared with clinical outcomes in this 10-year case series from a single centre in Dundee, UK. An online questionnaire (survey-monkey, a TM brand of online survey available for free for basic use) was sent to Scottish Dermatologists to gauge their opinions and confidence in the management of DI. Also, a retrospective review of medical case notes of patients seen by dermatologists in one institution was undertaken and clinical outcomes were reported by patients\' general practitioners (GP). The survey showed that 61% of responding dermatologists encountered 1-5 cases of DI per year. Twenty-four percent respondees were \'confident\' in managing patients with DI, 54% were \'somewhat confident\'. Forty-seven patients (62% female, 70% single) were seen over the 10 years; 43% brought a self-collected specimen to clinic, 68% of patients had a psychiatric comorbidity, 23% of patients had primary DI and 11/47 (23%) were seen by a psychiatrist. Clinical outcomes as rated by patients\' GPs were reasonable or good in 2/3 patients. A poor outcome was seen in 12 patients and associated with chronic pain in 50% (p < 0.01) and psychiatric comorbidity in 100% (p < 0.01). We conclude that good outcomes can be achieved in some patients with DI without psychiatric input and without psychoactive treatment.
