Solitary Peutz-Jeghers type hamartomatous polyp is a variant of PJS characterized by the presence of hamartomatous polyps in the absence of other manifestations of PJS. It is quite rare with only 19 cases reported in English literature. These cases present in older individuals are usually asymptomatic and carry increased risk of malignant transformation. Hamartomatous polyps are characterized histologically by tree-like branching of smooth muscle fibres covered by mucosal tissue of near normal appearance. Endoscopically, they are characterized by a lobular or nodular surface and whitish colour. We are presenting a case of giant Solitary Peutz-Jeghers type hamartomatous polyp of the duodenum who presented with symptoms of gastric outlet obstruction that was treated with pylorus preserving pancreaticoduodenectomy.
