Mucinous borderline tumor involving fallopian tube: case report and review of the literature.
(61/75)
We report the case of a 74-year-old woman with a primary mucinous borderline tumor of the fallopian tube coexisting with an ovarian mucinous borderline tumor. Data were obtained through histopathologic study of the excised surgical specimen. p53, estrogen receptor (ER) and PAX8 expression were evaluated by immunohistochemistry on the available right fallopian tube and ovary. Both the ovarian and fallopian tube borderline ovarian tumors were negative for p53, ER and PAX8. However, the staining pattern highlighted the transition from a normal ciliated cell to neoplastic epithelia in the fallopian tube fimbria. This is the first report to indicate that mucinous borderline tumors may arise from the ciliated cells at the fallopian tube fimbrial epithelia. ER and PAX8 are useful markers in identifying the transition and origination of these tumors. (+info)
Pancreatic mucinous cystic neoplasm with sarcomatous stroma metastasizing to liver: a case report and review of literature.

Mucinous cystadenocarcinoma arising in an ectopic kidney simulating a retroperitoneal dermoid cyst: a rare tumour presenting as a diagnostic dilemma.
(64/75)
Primary mucinous cystic neoplasms are rare tumours of the kidney, with a very few case reports in the literature. They arise from metaplasia of renal pelvic urothelium. We describe here a 45-year-old male who presented with pain in the abdomen and a lump in the left iliac fossa for two months. Ultrasound and CT scan showed a large, complex, heterogenous mass in the central abdomen and left iliac fossa, suggesting the possibility of dermoid cyst. Excision of the mass showed an enlarged multicystic kidney filled with mucin, destruction of renal parenchyma and a small viable area of grey white tumour. Histopathology revealed a peripherally located mucinous cystadenocarcinoma arising in the background of chronic pyelonephritis and mucinous metaplasia. We report this case for the rarity of the lesion and the associated clinical and radiological diagnostic dilemma. (+info)
