REPORT OF A CASE
A 60-year-old Filipino man in generally good health presented to our dermatology clinic with a 2-month history of a rapidly enlarging umbilical mass. The lesion started as a papule and had grown to occupy the entire umbilicus. The patient kept it covered with gauze and tape. Contact sensitivity to the tape developed (Fig 1 ). He had no history of weight loss, dysphagia, abdominal pain, early satiety, constipation, diarrhea, alteration in bowel habits, nausea, vomiting, hematemesis, melena, hematochezia, or jaundice. The physical examination revealed a well-appearing man with a 3.5-cm2 firm, nontender, fungating mass obliterating the umbilical space. Its surface was eroded with drainage of serosanguineous fluid. Rectangular erythematous eczematous plaques consistent with the tape dermatitis were present on both sides of the lesion. No other abnormality was found on physical examination. Lymphadenopathy was absent, and palpation of the abdomen demonstrated no masses. Routine laboratory studies
