can be confused with mucinous cystic neoplasm (MCN) or IPMN with invasive carcinomas due to its predominantly cystic imaging features.
confers a better prognosis than does ductal or tubular carcinoma (4) but has only been reported to arise from the intestinal subtype of IPMNs and not from IOPN.
Another female patient of colloid carcinoma
was 62 years old.
One is colloid carcinoma
, and the other is medullary carcinoma.
The remaining 2 cases included 1 case of colloid carcinoma
and 1 case of solid ACA with signet ring cell features.

(54) In the pancreas, however, mucinous colloid carcinoma
is microsatellite stable (and, therefore, stains diffusely with MLH1 and MSH2).

(6,18) These cases are difficult to differentiate from SPC with associated invasive colloid carcinoma
. (6) Nassar et al, (6) in their series, described one such case in which distant metastasis developed 10 years after diagnosis.
A morphological study of cells from colloid carcinoma
of the breast obtained by fine needle aspiration: distinction from other breast lesions.
Several histologic variants of pancreatic cancer have been described, which include adenosquamous carcinoma, colloid carcinoma
, medullary carcinoma, signet ring cell carcinoma, undifferentiated carcinoma, and undifferentiated carcinoma with osteoclast-like giant cells.
There were 5 (11%) "good" prognosis subtypes of invasive carcinoma, including tubular/cribriform carcinoma (Figure, D), colloid carcinoma
(Figure, E), and papillary-cystic carcinoma.
In the most recent WHO classification published in 2004, (17) pulmonary adenocarcinomas were divided into acinar, papillary, bronchioloalveolar, solid adenocarcinoma with mucin production, and mixed subtypes, as well as several variants (fetal adenocarcinoma, mucinous or colloid carcinoma
, mucinous cystadenocarcinoma, signet ring adenocarcinoma, and clear cell carcinoma).
