Mole on back

While listening to a 41-year-old patient’s lung sounds, the family physician (FP) noticed a mole that “stood out” on the upper right area of his back. The slightly raised pigmented lesion was 1 cm in diameter. The FP applied a dermatoscope to the skin to look for suspicious structures.

What's your diagnosis?

A closer look at the lesion (FIGURE 1) using the dermatoscope (FIGURE 2) revealed an atypical network, negative network, streaming pigment at the periphery, and a blue/white veil—suggestive of melanoma.

The FP performed a saucerization (scoop shave biopsy) and sent the full lesion to pathology. The report came back as a superficial spreading melanoma with a Breslow depth of 0.35 mm. The lesion site was then re-excised with 1 cm margins; no sentinel node biopsies were required.

In this case, listening to the lungs with the patient’s shirt off and noticing the "ugly duckling" lesion led to a lifesaving intervention.
