A 70 years old male patient admitted to our clinic with a 10 years history brown, macular lesion that is 1×1,5 cm in size and up on that lesion, a 1 year history, sharp edged, brown- black, verrucose, popular lesion that is protruded from the skin and is 0,5×0,5 cm in size (Figure 1a).
Skin biopsy taken from the lesion revealed hyperkeratosis, acanthosis, scattered melanocytes in the epidermis and lymphocytes and macrophages in the superficial dermis, but didn’t reveal any atypiaormitosis (Figure 1b).
What is your diagnosis?
What is your treatment approach?
We applied cryotherapy two times, and then the entire lesion cured (Figure 1c).
Melanoacanthoma is a solitary benign skin tumor that is common with middle- old aged people and is usually placed on the head, trunk, lips or eyelids. Melanoacanthoma can imitate the clinical presentations of seborrheic keratosis and malign melanoma. But characteristic histopathological attributes allow differentiation of these 3 diseases. Recently, melanoacanthoma is thought to a rare variant of seborrheic keratosis rather than a distinct entity. Melanoacanthoma is a benign skin tumor, so it can be treated with curettage, cryotherapy or simple excision.
