Question: What is the pathogen associated with the infection depicted by the image above?

Response: This is herpes zoster (shingles) and represents reactivation of herpes zoster (VZV infection) along the sensory ganglion of a dermatome.

The image above is showing VZV in one dermatome.

Remember that disseminated herpes zoster is defined by skin lesions in multiple dermatomes or crossing the midline. This can often be seen in immunocompromised hosts, such as transplant recipients, patients with hematologic malignancies, and/or those undergoing chemotherapy. This can be accompanied by visceral involvement.
