Minimal deviation adenocarcinoma of the uterine cervix is a very well-differentiated adenocarcinoma of the uterine cervix associated with Peutz-Jeghers syndrome.

It is also known as adenoma malignum and minimal deviation adenocarcinoma (abbreviated MDA).

It is a subset of adenocarcinoma of the uterine cervix, which is dealt with in the adenocarcinoma of the uterine cervix article.

General

Note:

  • Very well-differentiated adenocarcinoma may also be seen in the stomach;[6] however, this does not appear to be related to the well-differentiated adenocarcinoma in the cervix.

Microscopic

Features:[7]

  • Deep infiltrating glands - key feature.
    • Desmoplastic stroma - may be subtle.
    • Perivascular and/or perineural location.
  • Minimal nuclear atypia.
  • Abnormal gland morphology[5] / loss of lobular (gland) architecture. †

Note:

  • Not a criterion required by all pathologists.[1]
