A case of low grade appendiceal mucinous
neoplasm (LAMN) presented with right inguinal hernia with mucinous
cystadenoma of the appendix as content.
The examination of frozen sections established the diagnosis of serous or mucinous
BOT with 100% accuracy.
A rare case of incidental mucinous
adenocarcinoma with osseous metaplasia associated with cysts of the presacral space.
Benign serous cyst was the commonest benign tumour followed by mature cystic teratoma and mucinous
The most common differential diagnoses of urachal mucinous
cystadenoma include villous adenoma, mucinous
cystic tumor of low malignant potential (MCTLMP), and mucinous
The mucin is diastase and hyaluronidase resistant sialidase labile, thus making it nonsulfated sialomucin and distinguishable from hyaluronidasesensitive sulphomucin from other sweat gland tumors, basal cell carcinoma, lacrimal gland tumors, and metastatic mucinous
adenocarcinoma of the gastrointestinal tract.
(18) MCN is typically a solitary lesion, so if additional cystic pancreatic lesions are present, intraductal papillary mucinous
neoplasm or pseudocyst should be considered as an alternative diagnosis.
Case of mucinous
adenocarcinoma with porcelain gallbladder.
In almost all cases, confirmation of the diagnosis requires detection at laparotomy (14) or laparoscopy (28) of the jelly-like as-cites with mucinous
Histopathological examination confirmed the presence of prostatic adenocarcinoma with extraluminal mucinous
pools involving >50% of the tumor volume (Figure 5).
The number of patients with stage II medullary, mucinous
carcinoma were significantly higher than the other stages (p=0.02).
In invasive urachal adenocarcinoma, the following four subtypes are described in the 2016 WHO classification: mucinous
(colloidal) type with preponderance of extracellular mucin and malignant epithelia floating within, enteric (intestinal) type with preponderance of malignant stratified epithelium resembling colorectal adenocarcinomas, mixed type with neither a mucinous
nor an enteric pattern prevailing, not other specified (NOS) type with a pattern not easily identifiable as mucinous
or enteric type, and signet ring cell type with signet ring cell morphology prevailing.
