ABSTRACT

Melanoacanthoma is a rare lesion. Melanoacanthoma of external ear is still rarer. We present two cases of melanoacanthoma of external ear in adults which presented as pigmented growths and clinically were suspected as malignant lesions. Histopathology was diagnostic as it demonstrated the characteristic elevated lesion with abundant melanin pigment. No recurrence of the lesion was reported after four years of initial diagnosis. These cases have been presented because of their uncommon location, highlighting the differential diagnoses.

Key words:

External ear - malignant melanoma - melanoacanthoma
