Two cases of mucinous cystadenoma of the appendix successfully treated by laparoscopy are reported. An 81-year-old woman with lower right back pain was diagnosed with mucinous cystadenoma of the appendix or appendiceal carcinoma and underwent elective laparoscopic surgery. The other case involved a 70-year-old man with hematochezia who was diagnosed with mucinous cystadenoma. He also underwent ...

UNLABELLED Cystadenocarcinoma is primarily characterized by cystic structures of varying sizes, that are lined by epithelial cells. As a rare neoplasm, only four cases of cystadenocarcinoma of submandibular glands have been previously reported. Herein, we reported a unique case of submandibular gland cystadenocarcinoma in a 44-year-old man. By in large, this case had typical morphologic cystade...

Tumor associated antigen present in the cyst fluid of a patient with papillary mucinous cytadenocarcinoma of the ovary was prepared by ammonium sulfate precipitation. The dialyzed precipitate was emulsified in complete Freund's adjuvant and injected into rabbits followed by booster doses of the antigen in saline. The resulting antiserum was absorbed with normal human serum and normal liver and ...

CONTEXT Sister Mary Joseph's nodule usually represents metastatic cancers from gastrointestinal malignancy including adenocarcinoma of the pancreas. Mucinous cystadenocarcinoma is a rare malignancy of the pancreas. However, pancreatic mucinous cystadenocarcinoma metastasized to Sister Mary Joseph's nodule is much rarer and has never been reported before. CASE REPORT A 73-year-old Thai woman p...

Sertoli-Leydig cells tumors are rare ovarian neoplasms that can be managed with conservative resection given their generally excellent prognosis. Here we report a case of Sertoli-Leydig cell tumor mistakenly diagnosed as an invasive mucinous adenocarcinoma at time of intraoperative consultation because of its blue-mucinous appearance in the frozen section material. The patient subsequently unde...

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...

We report here on a case of mucinous adenocarcinoma that probably originated in the renal pelvis of a horseshoe kidney. A 61-year-old woman presented with a palpable mass in the left upper quadrant of the abdomen, and this mass had been present for several months. Computed tomography (CT) revealed a left renal pelvic tumor in the horseshoe kidney. Grossly, a 10×9×8 cm unilocular cystic mass fil...

A 57 year old woman presented complaining of increasing abdominal swelling of six months duration. A mixed solid cystic left ovarian tumour measuring 24 cm in diameter was excised. Histology showed numerous cysts lined by benign mucinous epithelium blending imperceptibly into borderline clear cell and mucinous areas that in turn merged with an invasive clear cell carcinoma. To the best of our k...

Progressive mucinous histiocytosis is a very rare, benign, non-Langerhans' cell histiocytosis limited to the skin. In total ten patients (all women) in four families and three sporadic cases have been reported. We report here the first published case of a male patient with progressive mucinous histiocytosis. The multiple red papules on the scalp and forearms were asymptomatic and had slowly inc...
