Salah aldin Katanji, Meri Abdul Masih Kaurie, Mohammad Zuhair Rayya, Ali Zuhair Rayya, Rahaf Hussam Rayya, Raghad Mohammad Abo Kaias, Tibel Abdul Masih Kaurie, Mohammad Kokash, Bilal Sleiay, Mouhammed SleiayIntroduction 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.
