Abstract

As with most endocrine tumors, the malignant potential depends on evidence of local or distant invasion (metastasis), so it is important to differentiate synchronous/metachronous endocrine tumors from their metastases. A 90-year-old man was operated due to tumor of the ampulla of Vater. As the surgical specimen was examined macroscopically, a second tumor focus, measuring 1 cm in diameter, was detected at the duodenum. There were no clinical syndromes due to hormone hypersecretion. Microscopically, the ampullary tumor had trabecular and rosette-like patterns, with many necrotic areas. It had invaded the muscularis mucosa at the duodenal wall. The latter duodenal tumor was located in the submucosa and had distinct borders. This tumor consisted of trabecular structures with stroma rich in lymphoid aggregates. Immunohistochemistry revealed positivity for synaptophysin and gastrin and negativity for somatostatin. In addition, the whole antral portion of the Whipple resection material showed diffuse parietal cell hyperplasia. The tumors were diagnosed as well-differentiated endocrine carcinoma in the ampulla of Vater according to the WHO classification 2000, a gastrin-producing well-differentiated endocrine tumor in the first portion of the duodenum without regional lymph node metastases, and a diffuse parietal cell hyperplasia at the antral portion of the stomach. In conclusion, clinical findings and the postoperative diagnosis suggest that this patient had primary synchronous neuroendocrine tumors of the small intestine.

Özet

Çoğu endokrin tümörlerde malign potansiyel, lokal invazyon ya da uzak metastazın varlığına bağlı olduğu için, senkron/metasenkron tümörleri metastazlarından ayırt etmek önemlidir. Doksan yaşındaki erkek hasta, ampulla Vateri’deki tümöründen dolayı opere edildi. Makroskopik olarak cerrahi spesmen incelendiğinde, duodenumda, 1 cm çapında ölçülen ikinci bir tümör odağı tespit edildi. Hormon hipersekresyonuna bağlı klinik sendromları yoktu. Mikroskopik olarak ampullar tümör, birçok nekrotik alan ile birlikte trabeküler ve rozet benzeri paternlere sahiptir. Tümör, duodenum duvarında muskularis mukozayı invaze etmiştir. Duodenumdaki tümör submukozada lokalizedir ve keskin sınırlıdır. Bu tümör, lenfoid agregatlardan zengin stromayla birlikte trabeküler yapılardan oluşmaktadı r. İmmunohistokimya sinaptofizin ve gastrin için pozitif, somatostatin için negatif saptandı. Ek olarak, Whipple rezeksiyon materyalinin antral bölümünün tamamı diffüz parietal hücre hiperplazisi göstermekteydi. WHO 2000 sınıflamasına göre, ampulla Vater’deki tümör iyi diferansiye endokrin karsinom, bölgesel lenf nodu metastazı içermeyen duodenum birinci bölümdeki tümör gastrin üreten iyi diferansiye endokrin tümör ve midenin antral bölümünde diffüz parietal hücre hiperplazisi olarak tanı aldı. Sonuç olarak, klinik ve postoperativ bulgular hastada, ince barsakta primer senkron endokrin tümörler olduğunu düşündürmektedir.
