    Abstract Halo naevi are considered benign. They occur in children and adolescents. Eruptive multiple halo naevi are infrequently seen in adults. The first patient in this case series had previously had melanoma. Positron emission tomography-computed tomography (PET-CT) showed a papillary thyroid carcinoma. Subsequent adult patients underwent an examination programme similar to melanoma patients with unknown primary, including PET scanning. Sixteen patients were followed over a 6-year period. In total there were 2 papillary thyroid cancers, 1 neuroendocrine lung tumour, 1 patient had had lung metastases from a thin melanoma 7 years previously, 3 patients had primary cutaneous melanoma (1 had had halo naevi since excision of 2 melanomas 15 years previously) and 1 had melanoma metastasis with unknown primary. The incidence of melanoma was 955 times higher than expected (standardized incidence rate). The benefits of PET scanning must be validated in a controlled trial prior to implementation into clinical practice.

    Abstract Treatment of advanced melanoma has undergone a paradigm shift over the last 10-15 years. The frustrating results of studies on medical treatment ten years ago have been replaced by studies constantly improving survival in patients with advanced melanoma. Immune checkpoint inhibitors belong to one group of treatments and targeted therapy to another. Fifty percent of melanomas are BRAF mutation positive. Normally, the mitogen activated protein kinase or MAP kinase (Ras-BRAF-MEK-Erk chain) pathways translate external signals to intracellular growth and proliferation. In BRAF mutated melanoma cells, the mutated BRAF kinase is excessively active leading to autonomous proliferation and cancerous growth. This kinase can be blocked by BRAF-inhibitors. If given to BRAF negative melanoma patients, it may lead to disease progression because Ras is not inhibited in these cells. Development of Squamous cell carcinomas as a serious adverse event to BRAF inhibition may be caused by similar mechanisms in non BRAF mutated keratinocytes. A spontaneous and paradoxical loss of effect is seen with BRAF inhibitors due to various ways melanoma cells bypass BRAF. This is somewhat counteracted by the addition of a MEK1/2 inhibitor. Overall progression-free survival has increased from a median of two months for chemotherapy, via 7-8 months for BRAF inhibitor to 10-14 months for newer BRAF and MEK inhibitor combination therapy.

    Abstract This is a case report of a 15-year-old girl, who developed kerion Celsi on the vulva after contact with a pet rodent. The skin was extremely painful, highly red, severely inflamed and oozing, mimicking a bacterial abscess. The patient's general condition was barely affected. PCR identified Trichophyton mentagrophytes, successfully treated with terbinafin 250 mg for 12 weeks. The majority of incidents in 11 published cases were caused by T. mentagrophytes, sensitive to terbinafin. Knowledge of this rare inflammatory dermatophytosis may cause the surgeon to abstain from surgery and to "keep calm and kerion".
