Two-thirds of counties across the Appalachian region have no practicing dermatologist, according to a registry analysis — a workforce deficit that places millions of rural residents outside realistic driving distance of skin cancer screening and chronic disease management.

The analysis drew on dermatologist registry data to map physician coverage county by county across the Appalachian corridor, which spans 13 states from New York to Mississippi. The finding — 66% of counties with zero dermatologists — frames one of the sharpest geographic maldistributions of any specialty documented in recent workforce research.

What does the gap mean for patients?

For residents of the affected counties, the absence of a local dermatologist translates into concrete clinical consequences:

• Delayed evaluation of suspicious pigmented lesions, with downstream risk of thicker Breslow measurements at melanoma diagnosis
• Long travel times for biologic management of plaque psoriasis, where PASI-response monitoring requires in-person follow-up
• Interrupted care for chronic conditions such as atopic dermatitis and acne that need titration over multiple visits
• Reliance on primary care clinicians for initial skin cancer triage

The registry-based design distinguishes the study from survey estimates: it counted physicians actually registered to practice, not self-reported availability, which makes the two-thirds figure a hard lower bound on access barriers rather than a projection.

Why Appalachia concentrates the shortfall

Appalachian counties share the structural features that consistently predict specialty deserts — declining populations, lower median incomes, and thin hospital infrastructure. Dermatology practices cluster in metropolitan referral centers, and the specialty's high procedural revenue mix makes rural practice economics difficult to sustain.

The result is a pattern familiar from access research on other specialties: the counties with the highest burden of skin disease risk factors, including outdoor occupational UV exposure and older age distributions, are the counties least able to attract or retain a dermatologist.

How the analysis was conducted

The research team cross-referenced dermatologist registry records against county boundaries across the Appalachian Regional Commission's designated footprint. Counties were classified by presence or absence of at least one dermatologist; the headline result is the share recording none.

Registry analyses carry known limitations — a listed physician may practice part-time, and registry counts do not capture telemedicine reach. Even so, the two-thirds figure matches the scale of rural dermatology shortages reported in prior national workforce assessments.

What could narrow the gap?

Workforce researchers increasingly point to several levers for regions facing this profile of shortage: expanded teledermatology networks that extend specialist review into primary care clinics, loan-repayment and visa programs targeting designated shortage areas, and training pipelines that recruit students from Appalachian communities, who are statistically more likely to return to practice there.

For dermatology practices and health systems in Appalachian-adjacent metros, the data also define a referral geography: the counties without coverage represent the catchment demand that outreach clinics and satellite sessions could absorb.

The registry analysis gives planners a county-level map of where those interventions would land first. As teledermatology platforms mature and state boards clarify cross-state licensure, the two-thirds figure sets the baseline against which the next decade of access improvement in Appalachia will be measured.
