A woman in her 70s presented with an enlarged and variegated plaque on her left axilla, which she had had for 4 years. The lesion started as a small eczematous, pink-to-brown plaque. As the lesion was asymptomatic and slow growing, she did not initially seek treatment. Recently, the color of the lesion had changed to an alarming dark brown color (Figure, A). No breast mass or lymphadenopathy was observed. Her medical and family history was unremarkable. A skin biopsy specimen was obtained and submitted for further histopathologic analysis.
