Abstrakt:	In daily medical practice, scapular pain associated with cervical radiculopathy is commonly seen prior to the onset of pain of the upper extremity; however, the cause of the scapular pain is uncertain. We report a case of herpes zoster with simultaneous skin rash in both the upper extremity and interscapular region, which corresponds to the painful scapular region in case of C8 cervical radiculopathy. A 71-year-old healthy woman complained of shoulder and scapular pain followed by a blistering skin rash on both the ulnar side of her upper extremity and intrascapular region on the right side. She was diagnosed with herpes zoster and was prescribed amenamevir as oral treatment with vidarabine ointment. After 1 year, she still had mild causalgia on her III-V fingers and needed oral treatment with pregabalin. To our knowledge, this is the first case report of a herpes zoster rash in the upper extremity and intrascapular region simultaneously. We speculate that the rash in the two regions is caused by the varicella zoster virus (VZV) traveling from the same ganglion, probably the C8 ganglion, considering the dermatome of the rash area in the upper extremity and the intrascapular region correspond to the innervation zone of the medial branches of the dorsal ramus of the cervical nerve root, which resembles the scapular region in case of cervical radiculopathy. This phenomenon implies the mechanism of scapular pain is related to cervical radiculopathy. Further case reports are needed to confirm this.
