Those initials Derm, derm., or dermatol. on medical paperwork or clinic signs? They’re shorthand for dermatology or dermatologist.
What Do These Letters Actually Mean?
Dermatology is the medical specialty that handles everything from skin rashes to skin cancer. Doctors use these abbreviations everywhere—patient charts, hospital whiteboards, even prescription instructions—to save time and space.
Here’s what you’ll typically see:
- Derm. – short for “dermatology”
- dermatol. – another way to write “dermatology”
- Derm – often stands in for “dermatologist” (like in “Rx from Derm on call”)
Common Medical Credentials That Appear Alongside
See MD? That’s a Doctor of Medicine. DO means Doctor of Osteopathic Medicine. Both are fully licensed to practice medicine, but DOs get extra training in osteopathic manipulative treatment and often focus on whole-person care.

When Should You See a Dermatologist?
A dermatologist is a medical doctor who treats over 3,000 conditions—everything from stubborn acne to autoimmune blistering diseases. The American Academy of Dermatology suggests scheduling a visit if you notice:
- Rashes or lesions that won’t go away
- Moles that change in size, shape, or color
- Hair loss that feels sudden or severe
- Skin infections (think redness, swelling, or pus)
Still unsure? The AAD’s guidelines can help, or ask your primary care doctor for advice.
