Two prostatic and gastric adenocarcinoma cases with distant lymph node metastasis

Cancer patients with unknown primary site may have different
presentations. Hematogenous lymph node metastasis probability
should be also considered when evaluating patients with
right supradiaphragmatic lymph node metastasis. A 68-yearold
male with prostatic carcinoma and a 60-year-old male with
gastric carcinoma are presented here. The prostate specific
antigen (PSA) levels and free/total PSA ratio should be measured
in male cancer patients with unknown primary site, as we
did in our first patient and immunohistochemical PSA staining
in the metastatic lymph node, if necessary. Skin metastasis may
occur with lymphatic spread after hematogenous lymph node
metastasis, and these lesions might also be used as follow-up
criteria for response to the treatment.
