One of the first visible spots where these tumors metastasize is one of the left supraclavicular lymph node.

Sertoli–Leydig cell tumour (a sex-cord stromal tumor), is a testosterone-secreting ovarian tumor and is a member of the sex cord-stromal tumour group [2] of ovarian and testicular cancers. The tumour occurs in early adulthood (not seen in newborn), is rare, comprising less than 1% of testicular tumours. [ 1 ]
