This case report describes for the first time a case of pure testicular carcinoid preaortic lymph node metastases in a 25 year old patient with carcinoid syndrome. The simultaneous occurrence of intratubular germ cell neoplasia in the surrounding testicular tissue was identified by OCT4 and placental-like alkaline phosphatase positivity. This confirmed that the tumour had a germ cell origin in the testis, rather than being a metastasis from an extragenital carcinoid.
Abbreviations: ITGCN, intratubular germ cell neoplasia; PLAP, placental-like alkaline phosphatase
Keywords: testis; carcinoid; intratubular germ cell neoplasia; carcinoma in situ
