What appearance do the ulcers from HSV esophagitis typically have?

The ulcers caused by herpes simplex virus (HSV) esophagitis typically exhibit a "volcano-like" appearance. This description arises from the presence of raised, inflammatory edges surrounding the ulcer, which is characteristic of HSV infections. The central portion of the ulcer is often necrotic and can contribute to the “volcano” appearance, as it is surrounded by an inflamed halo. This morphology differs significantly from ulcers caused by other conditions, making it a key distinguishing feature in the diagnosis of HSV esophagitis.

Understanding this characteristic is crucial, as it helps healthcare providers recognize the clinical manifestations of herpes esophagitis, which is particularly important in immunocompromised patients or those with a history of HSV infection. Detecting this specific appearance can guide further diagnostic and treatment strategies effectively.
