Untracked Skin Lesions and Uncoded Diagnoses: The Gaps in Paper Dermatology — and How DERMIS Fixes Them

Quick answer: On paper, skin lesions are described in words and diagnoses go uncoded, so clinicians cannot objectively prove a lesion is growing or changing — risking missed skin cancers — and there is no surveillance data. DERMIS adds standardised lesion photography, dermoscopy image management, longitudinal comparison, and ICD-10 coding to fix this.

Key facts

• Serial, standardised photography is the objective way to detect whether a skin lesion is growing or changing over time — words and memory are not.
• On paper, a biopsy result often arrives on a separate sheet, disconnected from the consultation that ordered it.
• Uncoded skin-disease diagnoses produce no structured data, so dermatological conditions stay invisible to public-health surveillance.
• DERMIS provides an interactive body diagram, lesion measurement and photography, dermoscopy image import, and longitudinal lesion comparison in one record.
• DERMIS codes diagnoses to ICD-10, the standard that lets skin-disease data feed the Ministry of Health HMIS; it works in English and French.

Why does paper dermatology miss important changes?

Dermatology is a visual discipline. The single most important question about many skin lesions — is it changing? — can only be answered by comparing how the lesion looks now with how it looked before. On paper, that comparison is impossible to do well. A note might say "pigmented lesion, left shoulder, approx. 6 mm" at one visit and "pigmented lesion, left shoulder" at the next, with no image and no consistent measurement. The clinician is left relying on memory and prose.

The problem compounds when different clinicians see the same patient. A lesion described by one doctor at one visit cannot be reliably re-found, re-measured, and re-judged by another doctor months later without a photograph taken to a consistent standard. Without an image baseline, every visit effectively starts over.

Diagnoses fare no better. On a paper chart a diagnosis is free text — "eczema", "fungal infection", "suspicious mole" — never translated into a structured, coded entry. That single gap quietly removes dermatology from every dataset that depends on coding.

What harm comes from untracked lesions and uncoded diagnoses?

The most serious risk is a missed skin cancer. Melanoma and other skin cancers are often caught precisely because someone notices a lesion has grown, changed colour, or changed shape. When there is no standardised photograph and no recorded measurement to compare against, a slow, dangerous change can be mistaken for "looks about the same" — and the window for early, curable intervention narrows. The same is true for chronic and progressive skin disease, where objective tracking is the difference between knowing a treatment is working and merely hoping it is.

A second harm is the disconnected biopsy. When a lesion is sampled, the histology result is the answer to a specific clinical question asked on a specific day. On paper, that result frequently comes back on its own sheet and is filed — or lost — apart from the consultation note that prompted it. The clinician who needs to act on it may not have the original photo, the measurement, or the differential diagnosis in front of them. The clinical thread is broken at the moment it matters most.

The third harm is invisibility. Because paper diagnoses are never coded, there is no surveillance data for skin disease. No one can answer how many cases of a given dermatological condition a district saw this quarter, whether a fungal or infectious skin problem is rising, or where skin-cancer suspicion is concentrated. Decisions that should be driven by data are instead driven by impression.

How does DERMIS solve lesion tracking and coding?

DERMIS — the Dermatology Information System — is built around the way dermatology actually works: looking, measuring, photographing, and comparing over time.

Its Skin Examination module starts with an interactive body diagram. Instead of describing "left shoulder" in prose, the clinician marks the exact site on the diagram, so every lesion has a fixed, unambiguous location that any colleague can find again. For each marked lesion, DERMIS captures a measurement and a standardised photograph, building a visual record rather than a verbal one. Where dermoscopy is used, DERMIS supports dermoscopy image import, so the magnified view sits alongside the clinical photo in the same record.

The capability that paper can never offer is longitudinal lesion comparison. Because each lesion is anchored to a body-diagram location and photographed to a consistent standard, DERMIS lets the clinician place this visit's image next to previous visits' images and see — objectively — whether the lesion has grown or changed. That is exactly the evidence needed to catch a developing skin cancer early, or to confirm that a chronic condition is responding to treatment.

DERMIS also closes the biopsy loop. Its Investigation Orders module sends a skin-biopsy request directly to OPES Lab, schedules patch tests, and — crucially — auto-returns the result to the consultation that ordered it, filing the histology report against the same lesion and the same patient. The result is no longer a stray sheet of paper; it is attached to the clinical question that produced it.

Finally, DERMIS makes dermatology countable. Every diagnosis is coded to ICD-10, the international standard, so skin-disease data becomes structured data that can feed the Ministry of Health HMIS. For the first time, dermatology contributes to surveillance instead of disappearing from it. For more on why coding is the foundation of health data, see our guide to ICD-10 and ICD-11 medical coding standards.

How does DERMIS connect dermatology to the wider record?

A skin consultation is rarely self-contained, and DERMIS is built as part of the OPES ecosystem rather than a stand-alone tool. Biopsies, cultures, and patch tests flow to and from OPES Lab, so specimen requests and results live in the same connected system — the same integration discipline that underpins strong laboratory information systems in Cameroon.

Treatment connects too. Topical and systemic prescriptions written in DERMIS are handled through PHARMIS, the pharmacy module, so what the dermatologist prescribes is dispensed and tracked rather than handwritten and lost. And because the patient's broader history sits in OPESCare, the clinician sees prior diagnoses, allergies, and medications on the same consultation screen — context that matters when a skin sign is the first clue to a systemic disease. If you are new to how these modules fit together, our overview of what a hospital management system is explains the shared-record foundation that DERMIS builds on.

Frequently Asked Questions

Why is photographing skin lesions better than describing them in notes?

Because change is what matters, and change is visual. A written note cannot reliably capture whether a lesion has grown a millimetre, darkened, or changed shape between visits. A standardised photograph can, and serial photographs placed side by side give an objective baseline that prose and memory cannot. DERMIS captures that photograph, anchors it to an exact body-diagram location, and enables direct longitudinal comparison.

Can DERMIS handle dermoscopy images?

Yes. DERMIS supports dermoscopy image import within its Skin Examination module, so the magnified dermoscopic view is stored alongside the clinical photograph and measurement for the same lesion, in the same patient record.

How does DERMIS connect a skin biopsy to the consultation?

Through its Investigation Orders module. A skin-biopsy request goes from DERMIS directly to OPES Lab, and the result is auto-returned and the histology report filed against the originating consultation, lesion, and patient — so the answer is attached to the clinical question instead of arriving on a separate, easily lost sheet.

How does coding dermatology diagnoses help public health?

Coding turns free-text impressions into structured data. By coding every diagnosis to ICD-10, DERMIS lets skin-disease information feed the Ministry of Health HMIS, making it possible to count cases, spot trends, and direct resources. Without coding, dermatology produces no surveillance data at all.

Conclusion

Paper dermatology fails at the two things skin care depends on: proving objectively whether a lesion is changing, and turning diagnoses into data. The cost is real — missed early skin cancers, biopsy results adrift from the consultations that ordered them, and a discipline invisible to public-health surveillance. DERMIS closes both gaps with standardised lesion photography, dermoscopy management, longitudinal comparison, integrated biopsy ordering, and ICD-10 coding — inside one bilingual, connected record.
