A twenty-five-year-old female presented with a large retroperitoneal mass. Workup included history and physical exam, imaging, biopsy, colonoscopy, and gynecologic exam. After surgical resection, the mass was determined to be a primary retroperitoneal mucinous tumor (PRMT). Clinically and histologically, these tumors are similar pancreatic and ovarian mucinous neoplasms. PRMTs are rare and few ...

Primary cutaneous mucinous carcinoma (PCMC) is a rare non-melanoma skin cancer that most commonly presents in the face. This malignancy is difficult to differentiate from metastatic mucinous carcinoma with a visceral source. Thus, PCMC is a diagnosis of exclusion, after internal malignancy has been ruled out. Given its rarity, there is currently a paucity of sound evidence behind its diagnosis ...

Primary appendiceal mucinous adenocarcinoma is a rare entity, while appendiceal carcinoma invading the urinary bladder is even rarer. The current study presents the case of a 54-year-old male with primary appendiceal mucinous adenocarcinoma, without gastrointestinal symptoms, presenting only with signs of bladder irritation. Abdominal computed tomography scans demonstrated a mass at the right a...

I read with interest the report of mucinous (so-called colloid) carcinoma of the lung by Dr. Rossi and colleagues (Am J Surg Pathol Vol. 28, April 2004). They attribute the first reported case of what was probably a mucinous cystadenoma of lung to Gowar in 1978, and note subsequent reports of mucinous or colloid carcinomas of lung. In fact, I believe the first report of primary mucinous (gelati...

High grade mucinous urothelial carcinoma is a rare pathological variant. There is still controversy as to its nomenclature and classification. We report the case of a 64 year old female with history of pelvic pain who was incidentally discovered to have a left upper pole renal mass. Left nephroureterectomy was performed and histopathological examination revealed high grade mucinous urothelial c...

BACKGROUND/AIMS Mucinous gastric carcinoma (MGC) is a rare histopathological type of gastric carcinoma, for which the clinicopathological features and prognosis remain controversial. To clarify the clinical significance of mucinous histological type in gastric cancer, we studied clinicopathological characteristics of MGC tumors and prognosis of patients. METHODOLOGY Forty-one patients with MG...

The purpose of this study was to explore the possibility of targeted molecular therapy with anti-epidermal growth factor receptor (anti-EGFR) antibody (cetuximab) for the treatment of mucinous ovarian carcinoma. We analyzed EGFR protein expression and KRAS gene mutations in 5 mucinous ovarian carcinoma cell lines RMUG-L, RMUG-S, MN-1, OMC-1 and MCAS and evaluated the in vitro and in vivo effect...

Mucinous carcinoma of the breast is one of the rarer forms of intramammary cancer, often presenting as a lobulated, fairly well circumscribed mass on mammography, sonography, and gadolinium-enhanced magnetic resonance imaging. It accounts for 1% to 7% of all breast cancers and generally carries a better prognosis than other types of malignant breast cancers. Metastatic disease occurs at a lower...

A gastric carcinoma with the endoscopic features resembling submucosal tumor (SMT) is rare, and reportedly account for only 0.1% to 0.63% of all resected gastric carcinomas. The preoperative diagnosis of SMT-like gastric carcinoma is challenging, and thus, diagnosis is usually made intraoperatively or postoperatively. Furthermore, mucinous adenocarcinoma is an uncommon histologic subtype of gas...
