Primary mucinous adenocarcinoma of renal pelvis is a rare cystic neoplasm which mimics a hydronephrosis or pyonephrosis radiologically. We are presenting here a case report where mucinous cystadenocarcinoma of pelvicalyceal system was mimicking clinically and radiologically as pyonephrosis but diagnosed preoperatively through a simple and rapid test, Ultrasoundguided fine-needle aspiration cyto...

INTRODUCTION There are few cases of synchronous rectal adenocarcinoma revealed by an anal fistula. The diagnosis of synchronous mucinous adenocarcinoma of the recto sigmoid and anal canal remains difficult. The chronic anal fistula can be mistaken as the common manifestation of a benign perianal abscess or fistula. CASE PRESENTATION We present a rare case of a Greek Caucasian 79year old male ...

[Introduction] Ovarian tumors may exhibit various morphologic appearances, and specific diagnosis on MR imaging is often difficult. 1-H MR spectroscopy (MRS) provides metabolic information, and may add valuable information for the diagnosis. The choline peak (3.2 ppm) may be observed in solid tumoral components reflecting metabolic activity of tumor cells and tend to show higher peaks in malign...

BACKGROUND Distant metastasis of mucinous adenocarcinoma from the gastrointestinal tract, ovaries, pancreas, lungs, breast, or urogenital system is a well-described entity. Mucinous adenocarcinomas from different primary sites are histologically identical with gland cells producing a copious amount of mucin. This report describes a very rare solitary metastasis of a mucinous adenocarcinoma of u...

We studied the staining patterns of bronchioloalveolar carcinoma (BAC) with antibodies to cytokeratin (CK) 7, CK20, and thyroid transcription factor-1 (TTF-1) to determine the diagnostic usefulness of this panel in differentiating BAC from metastatic adenocarcinoma in material obtained by fine-needle aspiration biopsy (FNAB) of the lung. We identified 16 cases of BAC. Of these, 6 were mucinous,...

PURPOSE To elucidate the molecular mechanisms contributing to the unique clinicopathologic characteristics of mucinous ovarian carcinoma, global gene expression profiling of mucinous ovarian tumors was carried out. EXPERIMENTAL DESIGN Gene expression profiling was completed for 25 microdissected mucinous tumors [6 cystadenomas, 10 low malignant potential (LMP) tumors, and 9 adenocarcinomas] u...

BACKGROUND To evaluate differences in the clinical characteristics and molecular pathology of lung adenocarcinoma subtypes as defined by the new International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society international histological classification. METHODS We retrospectively reviewed 269 patients with initial primary lung adenocarcinoma who had...

Primary mucinous adenocarcinoma is an extremely rare type of bladder cancer, with aggressive behavior and poor response to chemotherapy and radiotherapy. The symptoms are similar to those of other bladder tumors. Surgery is the main treatment and remains the only curative option. There may be a progression from mucinous metaplasia to mucinous adenoma and then mucinous adenocarcinoma. We present...
