title: Herpes zoster segmental paresis in an immunocompromised breast cancer woman.
abstract: Herpes zoster is an infectious disease with neurological complications caused by reactivation of varicella zoster virus in dorsal root ganglia of spinal cord which is also known as "Shingles." Suppression of immune system is the major predisposing factor for reactivation of latent virus. Disease is mainly characterized by rash, vesicles and pain along one or more dermatomes which are innervated from one or more spinal nerve roots. Complications may be present after a while despite of patient treatment. Motor involvement is included. Some previous studies showed segmental zoster paresis as a rare complication, a few weeks after first presentation, among immunocompetent individuals. We present post herpetic motor involvement of C5 and C6 in a 59-year-old woman who underwent chemotherapy and radiotherapy due to breast cancer, manifesting left upper limb weakness and paresis, 6 months after left partial mastectomy. Segmental paresis of zoster virus should be considered as a cause of motor impairment in an immunocompromised person suffering from shingles.
