Dermoscopic characterization and image study of a Sister Mary Joseph nodule in a patient with esophageal cancer

A Sister Mary Joseph nodule (SMJN) is rare cutaneous metastasis spreading to the umbilicus. It originates mostly from an intra-abdominal or pelvic malignancy and is an ominous sign. In this paper, we report a case of a SMJN in a 64-year-old man with esophageal cancer. We recorded his clinical progression, radiologic and nuclear scintigraphic images, and histopathologic and dermoscopic findings. The image study provided information on the localization of the SMJN and dermoscopy showed a polymorphous vascular pattern. The patient received palliative therapy because of terminal disease.
