Background: The rapid appearance of multiple new melanocytic nevi is known as eruptive nevi and has been well documented to occur with certain medications, in particular chemotherapeutic agents. Methods: We report a case of a woman with melanoma complicated by nodal metastasis who developed multiple melanocytic nevi while on high-dose interferon. Results: Serial photographs confirmed that the pigmented lesions were of new onset, whereas histology documented that the lesions were dysplastic nevi. A survey of the literature documented numerous causes of eruptive nevi, which we review. To date, interferon has not been linked to eruptive nevi. Conclusions: The phenomenon of eruptive nevi has been attributed to medications, bullous dermatoses, immunosuppression, and systemic conditions and is possibly a paraneoplastic disorder. Interferon appears to be another possible cause of this disorder.

Introduction Favipiravir is an antiviral agent that is recently used for SARS-CoV2 infection. The drug-drug interactions of favipiravir especially with chemotherapeutic agents in a patient with malignancy are not well known. Case report The patient diagnosed with metastatic osteosarcoma was given high dose methotrexate treatment, and favipiravir was started on the third day of the treatment with suspicion of SARS-CoV2 infection. Grade 3 hepatotoxicity developed after favipiravir. Management & outcome: The acute viral hepatitis panel and autoimmune liver disease panel were negative. The ultrasound of the abdomen was unremarkable for any hepatobiliary pathology. The all viral and hepatobiliary possible etiological factors were ruled out. The patient’s liver enzymes increased just after (12 hours later) the initiation of favipiravir, and we diagnosed toxic hepatitis caused by favipiravir-methotrexate interaction. Therefore, methylprednisolone 1 mg/kg dose was started for a presumed diagnosis of toxic hepatitis. Hepatotoxicity completely regressed after favipiravir was discontinued. Discussion Favipiravir may inhibit methotrexate elimination by inhibiting aldehyde oxidase and its sequential use may cause hepatotoxicity in this case. The clinicians should keep in mind possible drug interactions while using new antiviral agents against SARS-CoV2 like favipiravir.

e21516 Background: The clinical efficacy of PD-1 inhibitors as an adjuvant treatment for Asian melanoma patients has not yet been determined. Methods: Thus, this single-centre, retrospective study analysed the clinical data of 90 Chinese patients with completely resected, stage III cutaneous or acral melanoma who received either adjuvant PD-1 inhibitor or high-dose interferon α-2b (HDI). Propensity score matching (PSM) was used to control baseline differences between the two treatment groups. The primary end point was recurrence-free survival (RFS), and the secondary end points included distance metastasis-free survival (DMFS) and incidence of first distant metastatic sites. Results: Anti-PD-1 treatment resulted in significantly longer RFS (18-month RFS, 53.3% versus 26.7%; 95% CI, 0.097-0.975; P < 0.05) and DMFS (18-month DMFS, 70.9% versus 46.1%; 95% CI, 0.13-0.945; P < 0.05) than HDI in cutaneous melanoma patients. However, adjuvant anti-PD-1 treatment had no advantage over HDI in acral melanoma patients (18-month RFS, 30.0% versus 35.9%; P > 0.05; 18-month DMFS, 36.5% versus 63.6%; P > 0.05). The incidence of lung metastasis at first in the anti-PD-1 group was found to be significantly lower (12.5% versus 48.5%; P < 0.05) in cutaneous melanoma patients than in acral melanoma patients, but no difference in metastatic sites were observed between the two treatment groups among acral melanoma patients. The incidence of treatment-related AEs was similar between the two treatment groups. Conclusions: In conclusion, adjuvant anti-PD-1 treatment was well tolerated and yielded a significantly better prognosis than HDI in Chinese patients with stage IIIB/C cutaneous melanoma, but a significant difference was not observed in those with acral melanoma.

<b><i>Background:</i></b> Caucasians with red hair and fair skin have a remarkably increased risk of malignant melanoma compared to non-redhead Caucasians. <b><i>Objectives:</i></b> With the aim of a reliable melanoma diagnosis in redheads, the application of dermatofluoroscopy was analyzed in 16 patients with red hair. Most of them had been included in a clinical dermatofluoroscopy study for patients with the suspicion of melanoma. We examined whether the 25 lesions of the redheads showed the same characteristic melanin fluorescence spectra for dysplastic nevi and melanomas as those of non-redhead Caucasians or whether there was a different fluorescence pattern. This is important in view of the known significantly altered ratio of eumelanin to pheomelanin in the skin of redheads. <b><i>Methods:</i></b> More than 8,000 spatially resolved fluorescence spectra of 25 pigmented lesions were measured and analysed. The spectra were excited by the stepwise absorption of two 800-nm photons (principle of dermatofluoroscopy). Furthermore, the fluorescence spectra of eumelanin and pheomelanin in hair samples were determined in the same way. <b><i>Results:</i></b> The evaluation revealed that the melanin fluorescence spectra of dysplastic nevi and melanomas of redheads have the same spectral characteristics as those of non-redhead Caucasians. An accompanying result is that dermatofluoroscopy shows identical fluorescence spectra for eumelanin and pheomelanin. <b><i>Conclusions:</i></b> Dermatofluoroscopy proves to be a reliable diagnostic method also for redheads. Our results also explain our recent finding that there is a uniform fluorescence spectroscopic fingerprint for melanomas of all subtypes, which is of particular interest for hypomelanotic and apparently amelanotic melanomas containing pheomelanin.

Primary Central Nervous system lymphoma (PCNSL) is an uncommon type of central nervous system lymphoma, most commonly presenting as hemiparesis and headache. Currently, there is a wide range of treatments for PCNSL, consisting of various permutations between chemotherapy, radiation and autologous stem cell transplant (ASCT). Although the backbone of PCNSL treatment consists of High-dose Methotrexate (HD-MTX), the role of combination versus single agent chemotherapy, combined modality (chemotherapy + radiation) versus chemotherapy or radiation alone, and the use of consolidative ASCT are contested. Surgery does not have a role in the treatment of PCNSL although stereotactic biopsies tend to help with symptomatic relief. Radiation monotherapy is generally reserved for patients with contraindications to chemotherapy or as a palliative measure. Combined chemotherapy and radiation treatment has been shown to have a great efficacy, although its increased neurotoxicity compared to chemotherapy alone is a major drawback. A growing body of research is focused on comparing the efficacy of various chemotherapeutic regimens. Currently, the MATRix regimen comprising of HD-MTX(3.5g/m2)-cytarabine/rituximab/thiotepa is widely used. The additional survival benefit of ASCT is contested although its role in the treatment of refractory or relapsed PCNSL is generally agreed upon. Finally, intrathecal HD-MTX has been shown to have added survival benefit when added to the standard therapies. Further retrospective and prospective studies are required to compare the efficacy and toxicity of various treatment options, with a focus on different chemotherapeutic agents and ASCT.
