Introduction And Importance:
Blaschko-linear acquired inflammatory skin eruption includes lichen striatus and blaschkitis, which can be triggered by factors such as pregnancy and autoimmune diseases; a rare case in an elderly man post-prostatectomy illustrates the need for accurate diagnosis to prevent unnecessary treatment.
Presentation Of Case:
A 69-year-old man developed a pruritic vesicular eruption along Blaschko's lines after undergoing prostatectomy. All laboratory tests for viruses were negative, and the biopsy result indicated post-traumatic Blaschkoid dermatitis. The patient was treated with topical corticosteroids and antihistamines, and he experienced remarkable improvement with no relapse three months later.
Clinical Discussion:
Surgery-induced blaschkitis mimicking herpes zoster highlights the nonviral Koebner phenomenon, thereby preventing unnecessary antiviral use.
Conclusion:
Diagnosis of Blaschko-linear inflammatory eruptions should be made promptly to avoid misdiagnosis and prevent unnecessary use of antivirals. Further studies are needed on surgical trauma and cutaneous mosaicism.
