A Case of Psoriasis and Pseudohernia of the Abdominal Wall at the Site of Herpes Zoster-Wolf’s Isotopic Response

Abstract: The patient, a 77-year-old Asian male presented with herpes zoster in the left lumbar and abdominal regions 9 weeks before presentation. The infection dried up after 2 weeks but was followed by an erythematous scaly rash in the same region with left-sided abdominal elevation. Pathological examination revealed continuous parakeratosis and Munro microabscesses. Abdominal computer tomography revealed no abnormalities, suggesting psoriasis with herpes zoster and Wolf’s isotopic response to the pseudohernia of the abdominal wall.
