Intravascular B-cell lymphoma diagnosed by skin biopsy.

A 58-year-old man presented with unexplained fever, constitutional symptoms, worsening respiratory failure and gross, generalized oedema. He was eventually diagnosed with intravascular B- cell lymphoma on a random skin biopsy. Examination of the skin showed patchy erythema and induration, with peau d'orange. Despite multiorgan failure requiring intensive care, he responded dramatically to multiagent chemotherapy (six cycles of cyclophosphamide, doxorubicin, vincristine and prednisone) and is currently in clinical remission.

Mitochondrial dysfunction and rod-like lesions associated with administration of beta2 adrenoceptor agonist formoterol.

Formoterol, a selective beta 2-adrenoceptor agonist, has been introduced recently in the treatment of poorly controlled asthma. A patient is presented who developed myalgia and muscle weakness, associated with an elevation of creatine kinase (CK) during treatment with formoterol. Subsequent muscle biopsy demonstrated atrophic fibres lacking cytochrome C-oxidase and succinate dehydrogenase, suggestive of mitochondrial dysfunction. There were no inflammatory changes. Immunocytochemical analysis using antibodies to alpha-actinin-2 and alpha-actinin-3 demonstrated positive staining of 'rod-like' bodies in atrophic fibres. Clinical and biochemical improvement occurred following withdrawal of formoterol. Possible mechanisms involved in the development of myopathy are explored.
