Stage IA melanoma caught at total-body dermoscopy

Asymmetric pigmented lesion on the upper-back · 7 mm · ABCDE-positive with chaotic dermoscopic pattern — consistent with thin invasive melanoma.

Narrative

Eliana sits in the high-risk dysplastic-naevus phenotype band. Annual dermoscopic surveillance + total-body photography catches change-over-time signals that drive Stage IA-or-better diagnosis.

Asymmetric pigmented lesion 7 × 5 mm on the left upper-back. Chaotic dermoscopic pattern with atypical network, irregular streaks, and blue-white veil. ABCDE all positive. Suspicion for invasive melanoma (Breslow likely ≤ 1 mm).

Findings
  • 7 × 5 mm asymmetric lesion · upper back, left · Upper back, left7 mm
  • Atypical pigment network with irregular streaks · Lesion
  • Blue-white veil in inferior third · Lesion
  • No regional lymphadenopathy on palpation · Axilla
Differential diagnosis
  • Invasive melanoma (Breslow ≤ 1 mm)62%
  • Melanoma in situ20%
  • Severely dysplastic naevus12%
  • Pigmented BCC6%
Recommended actions
  • ▸Excisional biopsy with 2 mm margins within 2 weeks
  • ▸If invasive on histology: wide local excision per Breslow + sentinel-LN biopsy if T1b+
  • ▸Annual whole-body skin exam with dermoscopy + total-body photography
Caveats
  • AI dermoscopic reads are screening signals — histopathology is required.
  • Patient phenotype warrants lifelong dermatology follow-up.

What changed

The early-detection win

Annual dermoscopy with total-body photography surfaced a 7 mm change-over-time lesion — early excision averts a future Stage IV diagnosis.
