1 - clinical image
A 28-year-old woman consulted for a plantar bluish ulcerated lesion on his left foot which was present for 6 months.
Clinically, a melanoma was suspected.
2 - Dermoscopic image
Dermoscopy revealed:
- blue hue
- ulceration
- blue ovoid nest
in favor of a basal cell carcinoma.
but this lesion was excised and pathology revealed an eccrine poroma (or eccrine acrospiroma).
Dermoscopic features of eccrine poroma have been described similar to basal cell carcinoma except the spoke-wheel areas and leaf-like structures (1)
