Verbatim response from ChatGPT
Short answer: Often yes for many common rashes and benign lesions, but not always — especially when melanoma or another skin cancer is a concern. Teledermatology is a good triage tool, but it has limits and sometimes an in‑person exam and biopsy are needed for a definitive diagnosis.
What determines reliability
- Image quality: clear, focused photos (including close-up and a photo showing the lesion in context) greatly improve accuracy.
- Type of lesion: inflammatory rashes (eczema, acne, allergic rashes, fungal infections) are commonly diagnosed reliably from photos. Pigmented lesions (moles), subtle malignancies, and lesions that require dermoscopy or palpation are harder to judge.
- Clinical info: history (how long, change in size/shape/color, symptoms like bleeding/itching), medical/family history, and full‑body context matter.
- Use of dermoscopy: teledermoscopy (photo plus dermatoscope image) markedly improves accuracy for pigmented lesions; plain photos are less reliable.
- Provider expertise and workflow: board‑certified dermatologists doing live or asynchronous reviews are more reliable than AI-only apps.
When you should seek in‑person care urgently
- Any mole with ABCDE features (Asymmetry, Border irregularity, Color variegation, Diameter >6 mm, Evolving)
- New rapidly growing lesion, bleeding or nonhealing sore, hard/fixed nodule, or a persistent rash with systemic symptoms (fever, swollen glands)
- If the telederm recommends biopsy or is uncertain
How to send better photos
- Take several photos: one close‑up, one showing the lesion in context (from farther away), and one from an angle.
- Use natural light, no flash glare; put a coin or ruler next to the lesion for scale.
- Include photos of surrounding skin and any similar lesions.
- Note onset, changes, symptoms, medications, sun history, personal/family skin cancer history.
Choosing a telederm service (specific options)
- Teladoc / Amwell / MDLIVE: large telemedicine platforms that provide access to board‑certified dermatologists through live or store‑and‑forward visits; good if you want an insured visit and the option for follow‑up referrals.
- First Derm: asynchronous reviews by dermatologists, often fast and useful for quick assessments of rashes or worrying spots.
- DermatologistOnCall: offers video visits with board‑certified dermatologists and can prescribe or triage for in‑person care.
- SkinVision (app): CE‑marked AI tool for mole risk assessment and monitoring — useful for tracking but not a substitute for a dermatologist; should prompt in‑person evaluation if it flags risk.
- Curology: subscription/telederm model focused on acne and common skin conditions with dermatologist oversight — not for skin‑cancer evaluation.
(When choosing, prefer services that specify board‑certified dermatologists, HIPAA compliance, and clear pathways for in‑person follow‑up and biopsy referrals.)
Practical wrap-up
- Teledermatology is a reliable way to get quick expert triage and reassurance for many rashes and benign‑appearing lesions.
- For any changing, irregular, or suspicious mole — or if the telederm expresses uncertainty — get an in‑person dermatology visit so the lesion can be examined and biopsied if needed.
If you want, tell me what the lesion looks like and where it is, and I can tell you whether it’s reasonable to start with an online consult or go straight to urgent in‑person care.
