Colonic mucinous adenocarcinoma. H&E stain.
Mucinous adenocarcinoma of the lung is often cytologically bland as can be seen in this image; on the right is benign ciliated epithelium and on the left is mucinous adenocarcinoma. H&E stain.
Mucinous carcinoma, also mucinous adenocarcinoma, is an epithelial neoplasm that produces mucin. Mucinous carcinoma can arise in a number of sites. It is also known as colloid carcinoma.[1]
General
Prognostic significance dependent on the primary site:
- Breast mucinous carcinoma has a better prognosis.
- Colorectal mucinous carcinoma has a worse prognosis.[2]
- May be non-significant in esophagus if adjusted for grade and stage.[3]
Specific sites
- Ovarian mucinous adenocarcinoma.
- Mucinous prostate carcinoma.
- Mucinous breast carcinoma.
- Mucinous adenocarcinoma of the lung.
Gross
- Gelatinous-like material.
- May have a consistency similar to Jello.
Images
- Mucinous adenocarcinoma of the lung (flickr.com).
- Ovarian mucinous cystadenocarcinoma (flickr.com/euthman).
Microscopic
Features:
- Mucin - amphormous whispy or cream material.
- Cytologically atypical cells within the mucin.
- +/-Tumour without mucin.
- Maximum amount acceptable depends on the primary site (see proportion of mucin section below).
Note:
- Mucin alone -- should prompt a search for atypical cells, i.e. levels should be done.
DDx:
- Benign mucocele.
- Mucin extravasation - no malignant cells present.
- Adenoma with pseudoinvasion (pseudocarcinoma).[4]
- Adenocarcinoma with mucinous features - see proportion of mucin section.
- Other myxoid tumours - has an exhaustive long DDx.
Proportion of mucin
The criteria for diagnosing "mucinous carcinoma" varies by the anatomical site:
- Mucinous prostate carcinoma: > 25% of the tumour.[5]
- Mucinous colorectal carcinoma: > 50% of the tumour.[6]
- Mucinous gastric carcinoma: > 50% of the tumour.
- Mucinous (noncystic) carcinoma of the pancreas: > 80% of the tumour.[7]
- Mucinous breast carcinoma: > 90% of the tumour.[8]
- One source suggests: > 50% of the tumour.[9]

Molecular
- May be associated with a KRAS mutation.
IHC
IHC can be used to suggest a primary site for a mucinous adenocarcinoma:[10]
- Upper GI tract: CK7 +ve (38/41 cases), CDX2 -ve (4 +ve/41 cases).
- Lower GI tract: CDX2 +ve (42/42 cases), CK20 +ve (41/42 cases), CK7 -ve (8 +ve/42 cases) positive cases usu. in rectum/anus, beta-catenin (nuclear) +ve (27/42 cases).
- Breast: CK7 +ve (18/18 cases), ER +ve (16/18 cases).
- Lung: CK7 +ve (16/16 cases).
- Gynecologic: CK7 +ve (25/27 cases).
A panel:
- CK7, CK20, beta-catenin, CDX2.
Sign out
In biopsies:
- Adenocarcinoma with a mucinous component is probably the most objective way to sign out a case, if the primary site is not firmly established and a non-mucinous component is present.
OMENTUM, CORE BIOPSY: - METASTATIC MUCINOUS ADENOCARCINOMA, SEE COMMENT. COMMENT: The tumour cells stain as follows: POSITIVE: CK20, CDX2. NEGATIVE: CK7. The immunostains are suggestive of a lower gastrointestinal tract primary. Radiologic and endoscopic correlation is suggested.
