Lipomatous tumours of the tongue are rare and most of them are benign ordinary lipomas. In this report, we describe the first case of atypical lipoma of the tongue in a 78-year-old male, and review the current literature and controversies surrounding the nomenclature and biology of this unusual lesion.

Infliximab (Remicade), a chimeric monoclonal antibody to tumor necrosis factor-alpha (anti-TNF-alpha), is being used with increasing frequency in the treatment of Crohn's disease. Infliximab's safety profile to date has been good with reported adverse events being mild to moderate. We report a case of diffuse alveolar hemorrhage after the second infliximab infusion in a patient with Crohn's disease. The mechanism by which infliximab may have caused the observed pulmonary insult remains unknown. Physicians should be aware of the possible association between infliximab treatment and the development of alveolar hemorrhage. Future cases should be reported.
