An 86-year female patient was referred to us for assessment of lip lesions and numerous cutaneous warty growths of 6-month duration. She had mild dysphagia but no systemic symptoms, including weight loss. Her only medication was risedronate for osteoporosis and she was otherwise healthy. Examination revealed confluent fine papillomatosis across the lip vermillion (Fig 1), which diffusely affected the mucosa of the oral cavity and oropharynx. There were several wartlike papules affecting the skin of her face, neck, and extremities (Fig 2). There was no cutaneous hyperpigmentation or velvety thickening.Histologic examination of cutaneous and mucosal lesions showed hyperkeratosis, acanthosis, and papillomatosis but no viral inclusion or vacuolar degeneration of keratinocytes. There was no evidence of human papillomavirus (HPV) by polymerase chain reaction. Results of complete blood count and serum chemistry were normal but tumor markers showed elevated carcinoembryonic antigen (19.3 ug/L; normal, 0 to 4 ug/L), which was suggestive of a gastrointestinal tract neoplasm. A computed tomography scan showed marked mural thickening of the gastric body and antrum and several enlarged, confluent upper abdominal lymph nodes. Upper gastrointestinal endoscopy revealed gastric mucosal friability and ulceration. Biopsies demonstrated a poorly differentiated carcinoma. Palliative measures were provided when the patient experienced a rapid deterioration in health, and she died after 3 months.The eruption of wart-like papules was suggestive of a viral genesis but, surprisingly, there was no evidence to support the presence of
