A Case Report of Hereditary Palmoplantar Keratoderma with Esophageal Melanosis

Abstract

A 70-year-old man, a known case of diabetes mellitus since 10 years ago, presented with lower limb swelling and dyspnea on exertion for one month and dysphagia to solids associated with early satiety for 2 weeks. The patient had palmoplantar keratosis (PPK), which was present since birth with a similar family history. The patient was admitted to rule out esophageal malignancy. Upper gastrointestinal gastroscopy revealed esophagitis and esophageal melanosis with gastric mucosal erythema. Biopsies samples were taken. Histopathological examination revealed reflux esophagitis and chronic active Helicobacter pylori gastritis with no evidence of malignancy. His symptoms improved following H. pylori eradication and treatment for coronary artery disease and heart failure. The patient was advised of regular follow-up as he had risk factors for the development of esophageal melanoma or squamous cell carcinoma.
