Mucinous adenocarcinoma of the prostate is an uncommon type of prostate cancer.

General

  • Rare.[1]
  • Most often Gleason 3+4 ~ 80% in one series of 47 cases.[1]

Gleason pattern:

  • In the past, it has been suggested that the mucinous component be assigned Gleason pattern 4.[2]
  • The prognosis is similar or may be better than the conventional type of prostate cancer in a large series;[1] thus, it seems reasonable to grade based on the pattern (as advocated by some experts[3]).

Microscopic

Features:

  • Cytologically malignant cells floating in mucin.
  • > 25% of tumour mucinous.[2]
    • Two studies suggests >= 25%.[4][5]
