Surgical Care

Simple excision is curative for melanoacanthomas. Cutaneous melanoacanthoma is benign and may be removed with curettage. However, one theory suggests that cutaneous melanoacanthoma may be self-limited and it resolves without intervention.

Cryotherapy may be used if the diagnosis is certain and if histologic examination is not required. Additionally, argon plasma coagulation is a new treatment option for oral melanoacanthoma.[32]



A dermatologist should be consulted to confirm the diagnosis of melanoacanthomas.



Scarring can be expected after the surgical or cryotherapeutic removal of a melanoacanthoma. Melanoacanthomas that extend from the upper eyelid to beyond the lower eyelid can obstruct the patient's vision.


Long-Term Monitoring

Standard follow-up care may be needed to assess healing and address cosmetic issues.
