An extensive investigation including a computed tomographic scan of the abdominal and pelvic region as well as both 123I-labeled metaiodobenzylguanidine and 111In-coupled octreotide scintigraphy was normal. Because histopathologic examination of the primary surgical specimen revealed tumor growth in the resection border of the spermatic vessels, a second operation with unilateral lymph node dissectionwas performed. Surprisingly, 3 lymph node metastases were found. No further treatment was given and the boy is alive without disease 9 years after surgery. This case illustrates that modern scintigraphic techniques do not always detect carcinoid tumors. Because carcinoids respond poorly to other treatment modalities, the importance of initial radical surgery including a meticulous examination of regional lymph nodes is emphasized.展开更多
