Adencoarcinoma of the prostate is by for the most common malignacy of the prostate and one of the leading causes of cáncer-related death in males.
Metastasis to the regional lymph nodes occurs frequently and indicates a poorer prognosis compared with patients without lymph node metastasis.
The images correspond to the FNA cytology of the inguinal lymph node that was performed in a patient of 74 years of age.
The FNA smears contained abundant tumor cells lying single or in aggregates. The cells varied widely in size and shape, the nuclei were round or oval, and the nucleoli were prominent and sometimes irregular in shape.
These morphologic features were interpreted as consistent with adenocarcinoma.
