The study, led by dermatology resident Amy Johnson with co-authors Jennifer E. Murphy and Kelly Scarberry, grew out of preliminary observations from several volunteer dermatology events affiliated with an academic hospital. Those early events suggested that certain categories of conditions, notably eczematous dermatitis and disorders of the skin appendages such as hair, nails, and sweat glands, appear disproportionately among people who lack regular dermatologic care or carry inadequate health insurance. Rather than relying on anecdote, the team decided to systematically collect and analyze information from every patient seen at their monthly free clinic over a full year.

The methodology was deliberately simple but thorough. Both patient-completed and provider-completed intake forms were collected at each clinic session and then analyzed to identify recurring patterns. The researchers looked at patients’ zip codes of residence, any history of skin cancer, the most common chief concerns that brought people through the door, the most common clinical findings recorded by providers, and the basic demographics of the patient population. This kind of structured intake analysis is uncommon in the free clinic setting, where documentation is often minimal and follow-up is difficult.

One of the central motivations for the study is the fragmented state of the existing literature. As the authors note, current reports on free dermatology clinics are piecemeal, consisting mostly of individual institutions describing their own clinical experiences. Those reports vary widely not only in the conditions encountered but also in the treatment capabilities available at each site. A clinic that can dispense medications operates very differently from one that can only offer diagnoses and referrals. By publishing a detailed single-clinic analysis, the Cleveland team aims to add a comparable data point that other programs can learn from, even while acknowledging the limits of generalizing from one location.

The authors argue that gathering information from single clinic reports, imperfect as it is, remains valuable because it allows organizers of new or growing clinics to pick and choose the best of all worlds approaches to clinic operations and patient care. If one program demonstrates that a particular triage workflow reduces wait times, or that a certain formulary covers the majority of diagnoses seen, other clinics can adapt those elements without reinventing them. In this sense, the study functions less as a definitive epidemiological survey and more as a practical blueprint built from real-world operational data.

The broader context makes the work timely. A nationwide cross-sectional survey published in the Journal of the American Academy of Dermatology in 2019, cited by the authors, examined access to dermatology services at free medical clinics across the United States and found that specialist care at such facilities is far from guaranteed. A 2024 scoping review in JMIR Dermatology further documented the role of dermatology in student-run clinics nationwide, highlighting both the educational value for trainees and the service gap these clinics fill. The Cleveland clinic adds a resident-run model to this landscape, positioning dermatology trainees as the primary providers under faculty oversight.

Health equity considerations run throughout the report. The authors situate their clinic in Cuyahoga County, Ohio, referencing the county’s 2022 Community Health Needs Assessment, and they cite prior research showing that limited English proficiency is associated with delays in melanoma diagnosis. These references underscore why zip code level analysis matters: mapping where patients travel from can reveal geographic clusters of unmet need and help clinics target outreach. For a specialty in which visual examination of the skin is the core diagnostic tool, barriers to access translate directly into later diagnoses of potentially serious conditions, including skin cancers.

The study also touches on the demographic dimension of dermatologic care, with skin of color listed among the article’s keywords. Dermatologic conditions can present differently across skin tones, and patients from underserved urban communities may face compounded barriers of cost, transportation, language, and a historical lack of trust in the medical system. A free clinic embedded in the community, staffed by trainees who see the same population month after month, offers a mechanism for building continuity of care that episodic volunteer events often cannot provide.

From a technical standpoint, the analysis of paired patient and provider intake forms is a low-cost, reproducible quality improvement tool. Patient forms capture self-reported concerns, insurance status, and demographic information, while provider forms capture clinical impressions and diagnoses, allowing the researchers to compare what patients worry about with what clinicians actually find. Discrepancies between the two can inform patient education efforts, while concordance validates triage assumptions. The authors performed statistical analysis on the collected data, with Murphy generating the tabular summaries included in the manuscript, and Scarberry providing oversight and guidance in study design.

Importantly, the authors are candid about scope. They describe their work as a preliminary, single-institution contribution and explicitly state that no datasets were generated or analyzed beyond the clinic’s own intake records. Yet their aspiration is clear: they hope the data will inform other clinics serving similar patient demographics and enable a more customized, evidence-driven approach to addressing the needs of uninsured and underinsured patients. In a health care system where dermatology remains one of the hardest specialties to access without insurance, even a modest, well-documented clinic analysis can help convert goodwill into measurable, repeatable care.

The study, conducted by Joseph McGrath, Evelyn Fagan, Kaeli Samson, Yue Zhan, and Adam Sutton, was approved by the University of Nebraska Medical Center’s institutional review board and carried out in accordance with the Declaration of Helsinki, with written informed consent obtained from every participant. The research team set out to systematically compare what patients say about their own skin lesion histories against clinical verification, a comparison that matters enormously because the entire architecture of skin cancer surveillance in many health systems rests on self-reported data gathered in intake questionnaires and verbal histories.

Actinic keratoses are rough, scaly patches that develop on chronically sun-exposed skin, most often in fair-skinned, older adults. They are technically keratinocyte dysplasias rather than frank malignancies, but they occupy a critical position on the continuum of cutaneous carcinogenesis. A subset of them can progress to squamous cell carcinoma, and their presence signals what dermatologists call field cancerization, a state in which broad swathes of skin have sustained enough ultraviolet damage that multiple lesions can arise simultaneously and independently across the affected area. Keratinocyte carcinomas, meanwhile, encompass basal cell carcinoma and squamous cell carcinoma, the two most frequent cancers in fair-skinned populations worldwide and cancers whose incidence continues to climb as populations age and cumulative ultraviolet exposure accumulates.

The problem with relying on patient recall for these conditions is baked into their biology and their clinical course. Actinic keratoses are frequently treated with destructive methods such as cryotherapy, in which liquid nitrogen obliterates the lesion without any tissue being sent to a pathology laboratory. A patient who has had a dozen such treatments over twenty years may genuinely not know whether any given rough patch was confirmed as an actinic keratosis, whether it was something benign like a seborrheic keratosis, or whether it was an early squamous cell carcinoma that was frozen off preemptively. The diagnostic label often exists only in billing codes or in the memory of a clinician the patient saw years ago, if it exists at all.

Keratinocyte carcinomas present a related but distinct recall challenge. Basal cell carcinomas are rarely life-threatening but frequently recur, and patients with one history of nonmelanoma skin cancer face substantially elevated odds of developing subsequent lesions, a relationship established in meta-analytic work going back to Marcil and Stern’s widely cited 2000 review in the Archives of Dermatology. Squamous cell carcinomas carry greater metastatic potential, making accurate history-taking even more consequential. If a patient underreports a prior squamous cell carcinoma, a clinician may underestimate risk and calibrate follow-up too loosely. If a patient overreports, the result can be unnecessary anxiety, redundant biopsies, and wasted health system resources. Either direction of error degrades the precision of epidemiological studies that depend on self-reported cancer histories as their exposure variable.

This is not the first time the validity of patient self-report in dermatology has been scrutinized. A landmark 2004 study by Ming and colleagues, published in the same Archives of Dermatology, examined the validity of patient self-reported history of skin cancer and found meaningful discordance between what patients reported and what medical records could substantiate. That work, along with the more recent effort by Kitrell, Crew, Wysong, and Sutton in 2023 to refine the classification of field cancerization, frames the conceptual backdrop against which the new Nebraska-led study operates. The field cancerization concept itself, originally coined in the head and neck oncology literature and since extended to sun-damaged skin, implies that patients with field disease are precisely the ones most likely to have long, complicated lesion histories that strain the limits of lay recall.

Health literacy adds another layer of complexity. A 2024 systematic review by Chang and colleagues in the Journal of Prevention examined the role of health literacy in skin cancer preventive behavior and highlighted how unevenly patients understand even basic distinctions between lesion types. Many patients use the phrase skin cancer loosely, applying it to anything their doctor froze, burned, or scraped. Others with genuine histories of malignancy may not register the diagnosis because the encounter was brief, the terminology was unfamiliar, or the lesion was treated in a setting where pathology confirmation never occurred. In epidemiological surveys, in genetic studies recruiting participants on the basis of skin cancer history, and in clinical trials of field therapies, these misclassifications propagate quietly through the data.

The methodological stakes extend beyond the clinic into the research enterprise itself. Countless studies of keratinocyte carcinoma risk factors, from tanning bed use to immunosuppression to genetic susceptibility loci, rely on questionnaires asking participants whether a physician has ever told them they had skin cancer. Validation studies like the one from the University of Nebraska team provide the sensitivity and specificity estimates that allow researchers to correct for misclassification statistically. Without such grounding, effect estimates can be biased toward or away from the null in unpredictable ways, and the direction of bias often differs for actinic keratoses, which are over-reported when patients conflate them with benign barnacles of aging, versus keratinocyte carcinomas, which may be under-reported when pathology confirmation was never communicated clearly.

The practical implications for clinical practice are equally significant. Dermatologists performing surveillance on patients with a history of field cancerization already know that these individuals require more frequent examinations, and the new findings underscore that the history a patient volunteers should be treated as a starting point rather than a settled fact. Wherever possible, clinicians and researchers seeking accurate keratinocyte carcinoma histories should corroborate patient report with pathology records, tumor registries, or prior biopsy reports. For actinic keratoses, where confirmation is often impossible because destructive treatment leaves no tissue to examine, the study’s findings argue for building explicit uncertainty into both clinical documentation and research instruments, perhaps by distinguishing between patient-recalled lesions and provider-diagnosed, pathology-confirmed ones.

What makes this research letter notable is not that it overturns any single dogma but that it quantifies a vulnerability running through a vast body of dermatological science and everyday clinical care. The authors, who declare no competing interests and report no external funding, designed the study so that statistical analysis was performed by dedicated biostatisticians within the University of Nebraska Medical Center’s Department of Biostatistics, with McGrath and Fagan contributing equally to the work. Their data cannot be shared openly, a restriction that protects participant privacy under the informed consent agreements patients signed. As skin cancer incidence continues to rise and as health systems increasingly depend on patient-reported outcomes and self-administered intake tools, including digital questionnaires and telehealth screening algorithms, the gap between what patients believe about their own skin and what has actually occurred on it becomes a variable that medicine can no longer afford to ignore. This study is a measured, careful reminder that in dermatology, as in much of medicine, the patient’s memory is a diagnostic instrument, and like any instrument, it needs calibration.
