Three differently timed presentations of dermatomyositis associated with advanced ovarian cancer

Each of the three patients reported in this article presented with dermatomyositis at various stages of their advanced ovarian cancer. Dermatomyositis was the presenting feature and preceded the diagnosis of ovarian cancer by several months in one patient. In another patient, dermatomyositis occurred just prior to the scheduled third cycle of palliative chemotherapy after surgical debulking for stage 4 disease. The third patient presented with pathognomonic diagnostic features of dermatomyositis after ovarian cancer recurrence. Diagnosis was delayed in at least two of these patients; however, once appropriately diagnosed, each patient responded well to immunomodulatory treatment. In one patient, initiation of oral prednisolone seemed to correlate with a steady improvement in her proximal myopathy. A pulsed methylprednisolone approach was used in another patient with conversion to a tapering dose of oral prednisolone to good effect. In the patient in whom the most severe myopathy affecting bulbar muscle groups was demonstrated, an infusion of 5 days of intravenous immunoglobulin produced an eventual improvement in her steroid-refractory myopathy.
