[About a case of primary laryngeal mucosal melanoma in a patient with medical history of oropharyngeal squamous carcinoma].

Introduction: Primary laryngeal mucosal melanoma is a rare tumour with a poor prognosis. Its often difficult diagnosis should rule out laryngeal metastatic localization of cutaneous melanoma.

Case Presentation: We report a case of primary laryngeal mucosal melanoma diagnosed in a 65-year-old man, treated 6 years previously with radio-chemotherapy and surgery for squamous cell carcinoma of the right lateral oropharyngeal region.

Indirect effects of severe acute respiratory syndrome coronavirus 2 on the kidney in coronavirus disease patients.

Among patients hospitalized for novel coronavirus disease (COVID-19), between 10 and 14% develop an acute kidney injury and around half display marked proteinuria and haematuria. Post-mortem analyses of COVID-19 kidney tissue suggest that renal tubular cells and podocytes are affected. Here we report two cases of collapsing glomerulopathy and tubulointerstitial lesions in living COVID-19 patients.
