- Symptoms that follow a dermatome, such as pain or a rash, may indicate a pathology that involves the related nerve root.
- Viruses that remain dormant in nerve ganglia, such as the varicella zoster virus that causes both chickenpox and shingles, often cause either pain, rash, or both in a pattern defined by a dermatome.

- The virus may spread from one or more ganglia along nerves of an affected segment and infect the corresponding dermatome (an area of skin supplied by one spinal nerve) causing a painful rash.
- Although the rash usually heals within two to four weeks, some sufferers experience residual nerve pain for months or years, a condition called postherpetic neuralgia.
-
- As many as 30% of sufferers have some dermatological symptoms (and 65% suffer such symptoms at some point), with 30% to 50% suffering from the classic malar rash (or butterfly rash) associated with the disease .

-
- The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration), secondary syphilis with a diffuse rash which frequently involves the palms of the hands and soles of the feet, latent syphilis with little to no symptoms, and tertiary syphilis with gummas, neurological, or cardiac symptoms.
- There may be a symmetrical, reddish-pink, non-itchy rash on the trunk and extremities, including the palms and soles.
- The rash may become maculopapular or pustular.
-
- Erythema multiform is a rash that appears as an auto-immune response to a predisposing agent: a bacteria, an immunization, an antibiotic (in this case, amoxicillin).
-
- A response can take the the form of a rash (urticaria, also known as hives), or, worse—anaphylaxis (a serious reaction that can result in death).
