Herpes zoster classically presents as a vesicular eruption along a single dermatome that correlates with the dorsal root ganglion in which varicella zoster virus (VZV) reactivates. Such cases most commonly involve a single thoracic dermatome, but other rare presentations of herpes zoster have been reported including multidermatomal herpes zoster. This letter reports a case of multidermatomal herpes zoster affecting cervical dermatomes C2-C5 and presents all previously published cases of multidermatomal herpes zoster in which involved dermatomes were reported to determine if this condition has a predilection for cervical dermatomes. A total of eight other cases were reviewed and involvement of cervical dermatomes was observed in 6 of 9 cases (66.7%). This suggests a propensity for multidermatomal involvement to affect cervical dermatomes beyond that encountered in classic herpes zoster. Clinicians should be aware of this presentation of herpes zoster especially in the head and neck region where the classic vesicular eruption may not be confined to a single dermatome.
带状疱疹的典型表现是沿单个皮节出现水疱疹，这与水痘-带状疱疹病毒（VZV）重新激活的背根神经节相关。此类病例最常累及单个胸段皮节，但也有其他罕见的带状疱疹表现被报道，包括多皮节带状疱疹。本文报告了1例累及颈段皮节C2 - C5的多皮节带状疱疹病例，并呈现了所有先前已发表的报告了受累皮节的多皮节带状疱疹病例，以确定这种情况是否对颈段皮节有偏好。共回顾了其他8例病例，9例中有6例（66.7%）观察到颈段皮节受累。这表明多皮节受累影响颈段皮节的倾向超过了经典带状疱疹中所遇到的情况。临床医生应意识到带状疱疹的这种表现，尤其是在头颈部区域，在该区域经典的水疱疹可能不限于单个皮节。
