Acquired hemophilia in malignancy

Acquired hemophilia is a rare but potentially morbid complication in patients with cancer. It may be seen in patients with hematologic neoplasms (usually lymphoproliferative disorders) or with solid tumors. Although the presence of an underlying malignancy portends a worse outcome, the literature suggests that the usual principles of treatment, including immunosuppression, apply to these patients. However, appropriate consideration should be given to the choice of agents, depending on individual risk factors for complications such as thrombosis and infection.
