[Yellow nail syndrome. A case report with postmortem study]

Abstract

Yellow nail syndrome is a rare disease of unknown aetiology. Patients with YNS have a characteristic yellowish-coloured nails, pulmonary alterations and primary lymphedema. To the best of our knowledge, only a few reports of autopsy findings in these patients have been published. Its aetiology possibly involves a primary malformation of larger lymph vessels. We describe autopsy findings not previously associated with yellow nail syndrome, such as expansion of mediastinal lymph-nodes and splenic sinusoids. The present autopsy reveals hitherto unreported findings associated with YNS, such as alterations in splenic sinusoids and mediastinal lymph-node sinuses.
