An 87-year-old woman developed erythema, induration and tenderness of the s
kin overlying each breast. One year before, she had undergone an axillary l
ymph node dissection because of metastases from melanoma. The primary site
was unknown. A skin biopsy showed pigmented tumor nests within the dermal l
ymphatic vessels, and immunohistochemistry confirmed the melanocytic origin
. The diagnosis of inflammatory metastatic melanoma was made.
