Dermoscopic Predictors of Tumor Thickness in Cutaneous Melanoma: A Retrospective Analysis of 245 Melanomas

| Sumario: | Introduction: The literature regarding the association of dermoscopic structures with Breslow thickness in melanoma is scarce, limited to small case series, and mostly outdated.
Objective: This study determined the dermoscopic patterns, colors and structures that are associated
with melanoma in situ, thin melanomas (<0.8 mm) and thick melanomas potentially requiring sentinel
lymph node biopsy according to current guidelines (≥0.8 mm).
Methods: A retrospective evaluation of 245 dermoscopic images of primary cutaneous melanoma
located on the trunk or limbs was performed by consensus of 2 dermoscopists.
Results: Red-pink, blue-gray and white color, blue-white veil, shiny white streaks, irregular vessels,
blue-black pigmentation, milky red areas, pseudolacunae, ulceration and rainbow pattern were associated with thickness ≥0.8 mm, whereas atypical pigmented network, regression and hypopigmented
areas were significantly associated with early melanomas.
Limitations: This is a retrospective study performed in a single institution. Melanomas of special
sites were excluded from our evaluation. Dermoscopy is based on subjective evaluations that depend
largely on the observers’ experience.
Conclusions: The identification of certain dermoscopic structures and colors might help in the discrimination between thin and thick melanomas.
