Previous studies have shown conflicting results on the prognosis of colorectal mucinous adenocarcinoma. This study compared prognostic characteristics of patients diagnosed with mucinous and non-mucinous adenocarcinomas in a Canadian series. Analyses were based on 165 colorectal mucinous and 1215 non-mucinous adenocarcinoma patients who were registered at the Ottawa Regional Cancer Centre from ...

benign renal cystic adenoma with out malignant features is a very rare entity. a 75 year old male with obstructive lower tract symptoms and vague flank pain was admitted and planned for nephrectomy of non functional kidney -due to long term nephrolithiasis- intra operative finding was a cystic hydronephrotic kidney filled by thick mucous secretions which turned out to be a cyst adenoma of kidne...

Secondary and primar neoplasms of the appendix are rare tumors found in approximately 1% appendectomy specimens, with epithelial neuroendocrine being more frequent. (1). Epithelial adenocarcinoma is most common malignancy mucinous (37%) non-mucinous (27%) histological subtypes. We present a clinical case.

Mucinous carcinoma of the breast is a well differentiated, rare histological type of invasive ductal carcinoma, seen in oldest median age (69 years). We describe a case of a 60 yr old female with large right breast mass of 10 years duration with no nodal involvement. The reasons to present this case are 1) Because of its rarity. 2) Despite having a large tumour size, the axillary lymph node ...

Primary mucinous lesions of the urinary system are extremely rare. We describe two cases of primary mucinous lesions of the urothelial tract. One case is of mucinous metaplasia in the bladder of a 40-year-old man presenting with frequent urination, urgency, and gross hematuria. The other case is of mucinous adenocarcinoma in the pelvis of an otherwise healthy 67-year-old man with left nephrolit...

Mucinous lesions of the appendix and ovary are commonly encountered in routine practice. There are several published classification schemes for appendiceal mucinous neoplasms with resultant inconsistent use of terms and clinical doubt. While nomenclature is more settled with regards to ovarian mucinous neoplasms, the difficulty here lies with distinguishing primary from secondary mucinous tumou...

We examined the expression of c-myc and mutations in the KRAS gene in ovarian mucinous tumors to explore the pathogenesis of these tumors and the feasibility of targeted gene therapy. Expression of c-myc protein and mutations in the KRAS gene in 24 cases of ovarian mucinous cystadenoma, 46 cases of ovarian borderline mucinous cystadenoma, and 46 cases of ovarian mucinous cystadenocarcinoma were...

OBJECTIVE Mucinous cystadenocarcinoma of appendix is a rare entity. Differentiating mucinous cystadenocarcinoma from mucinous cystadenoma is very challenging and depends on establishing the presence of malignant cells in the appendix wall. The invasion may be very difficult to assess in some cases, especially in early stages of the disease, which could have devastating prognostic effects on pat...

The DNA stemline of 45 mucinous breast carcinomas was determined by flow cytometry using paraffin embedded archival tissue sections. The material consisted of 26 pure mucinous and 19 mixed mucinous carcinomas. The patients were followed up for at least 15 years or until death. Nearly all pure mucinous carcinomas had a normal DNA stemline (25 of 26) with only one aneuploid tumour. Mixed mucinous...
