Diffuse Esophageal Squamous Papillomatosis: A Rare Disease Associated with Acanthosis Nigricans and Tripe Palms

摘要

Acanthosis nigricans with tripe palms is one of the skin manifestations of systemic conditions, as well as internal malignancy. There have been reports of this paraneoplastic condition's association with orocutaneous papillomatosis, but investigations into its relationship with diffuse esophageal papillomatosis are scarce. We report a case of acanthosis nigricans with tripe palms that was associated with diffuse esophageal squamous papillomatosis. A 40-year-old Thai woman with underlying systemic lupus erythematosus and secondary Sjögren's syndrome, who was recently diagnosed with acanthosis nigricans and tripe palms was investigated for occult gastrointestinal malignancy. An upper GI endoscopy revealed diffuse squamous papilloma along the entire esophagus and lower GI endoscopy revealed one pedunculated hyperplastic polyp 1 cm in size at the sigmoid colon. Long-term follow-up is needed to reassure these coexisting conditions belonging to benign systemic diseases without hidden malignancy.
