BACKGROUND: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-malignant proliferation of histiocytes of unknown aetiology. It was first recognised as a distinct clinicopathologic entity in 1969, and is classified as an idiopathic non-Langerhans cell histiocytosis. The disease process is usually self-limiting and often ...

Intraneural lipomas of the ulnar nerve or its branches are rare benign tumours. Although most intraneural lipomas present as asymptomatic tumours, some may present as compression neuropathies due to their location. In the majority of cases these tumours can be enucleated without damage to the nerve fibres.
