Herpes zoster virus reactivation in the lumbosacral dermatomal distribution is an
unusual site of manifestation and atypical in presentation than its usual sites in
thoracolumbar (D3–L2) and facial (V1) dermatomes. Here, we are reporting a patient
of marginal zone lymphoma who on fluorine-18 fluorodeoxyglucose (FDG) positron emission
tomography/computed tomography scan performed for chemotherapy response evaluation
showed hypermetabolic cutaneous and subcutaneous lesions in the right vulva and posteromedial
aspect of the right thigh along with ipsilateral pelvic lymph nodes involvement as
an incidental finding. Subsequently, FDG active lesions were considered to be as herpes
zoster virus reactivation rather than the recurrence of lymphoma and treated with
antiviral drug.
