Diagnostic Considerations

Also consider melanotic macule, pigmented melanocytic nevus, and pigmented malignant hidroacanthoma simplex. [38]

Melanocytic nevus may require distinction from a melanoacanthoma. [39] Seborrheic keratosis coincidentally associated with a melanocytic nevus may also be considered. [40]

Also consider cutaneous melanoma, including the variant called verrucous melanoma. [41] Additionally, oral melanoacanthoma may rapidly progress, mandating an incisional biopsy to rule out an oral melanoma. [42]
