We report a case of a 30-year-old woman who had complained of lower abdominal distension. She was noted to have a history of primary mucinous tumor of the left ovary (13.2 × 9.9 × 10.4 cm) that was removed surgically. Two years later she developed the same tumor on her left ovary (8.7 × 6.0 × 6.9 cm) and also had appendiceal mucinous tumor accompanied with acellular PMP. Final pathology reveale...

Mucinous neoplasms occur rarely in association with cystic teratoma, Sertoli-Leydig cell tumor, granulosa cell tumor or carcinoid tumor. Several cases of an ovarian stromal tumor with minor sex-cord elements have been reported in the literatures. However, there has been no report about an ovarian mucinous neoplasm coexisting with a stromal tumor with sex-cord elements yet. We report a case of a...

CONTEXT Diagnosis and treatment of cystic neoplasms of the pancreas increased significantly in the last decades. There are only a few Brazilian publications on these tumors. The majority of them are limited to reports of one or few cases. OBJECTIVE To present our experience with 27 patients with cystic neoplasms of the pancreas. METHODS Demographic data, clinical manifestations, diagnostic ...

Urachal mucinous tumor of uncertain malignant potential is very rare and is characterized by a multilocular cyst showing the proliferation of atypical mucin-secreting cells without stromal invasion. As in ovarian and appendiceal borderline tumors, it represents a transitional stage of mucinous carcinogenesis in the urachus. In addition, this tumor may recur locally and develop into pseudomyxoma...

background: inhibin is a dimeric glycoprotein that has a depressive effect on the anterior hypophyse secretion. the level of this tumor marker is undetectable in menopause women. in patients with gynecological cancer, especially granulosa and epidermal-type (mucinous), ovarian cancers considerable increase in the serum level of inhibin has been reported. the increased level of inhibin has been ...

Mucinous cystadenoma of the testis is a very rare tumor. Herein, we report a case of mucinous cystadenoma arising in the testis of a 61-year-old man, along with a literature review. Computed tomography showed a 2.5-cm-sized poorly enhancing cystic mass. Grossly, the tumor was a unilocular cystic mass filled with mucinous material and confined to the testicular parenchyma. Histologically, the cy...

A 65-year-old man was hospitalized due to an abdominal tumor. Several imaging studies showed multilocular tumors in the right hepatic lobe and in the pancreatic head, 4 and 7 cm in size, respectively. The hepatic tumor rapidly grew to 9 cm in 4 weeks, associated with a rapid increase in the serum carcinoembryonic antigen level from 125 ng/ml to 1,000 ng/ml. The pathologic diagnosis of the resec...

INTRODUCTION Primary pulmonary mucinous cystic neoplasia comprises a group of tumors, from benign cystadenoma to mucinous cystadenocarcinoma. CASE PRESENTATION We report a case of primary pulmonary mucinous cystadenocarcinoma in a 75-year-old woman who was found to have a right hilar mass on a routine chest X-ray. A lobectomy was performed and the resection specimen revealed a multicystic muc...

Mural nodules of ovarian mucinous borderline tumors are rare. In this study, we report a case of mural nodules of clear cell carcinoma in an intestinal type mucinous borderline tumor of the ovary. The patient was a 54-years-old woman presented with back and pelvic pain for 3 months. A right-sided multiloculated ovarian mass approximately 20 cm was identified on the CT scan. CA-125 was moderatel...

Primary retroperitoneal mucinous cystic tumors are extremely rare. These tumors can be classified as a primary retroperitoneal mucinous cystadenoma with or without borderline malignancy or primary retroperitoneal mucinous cystadenocarcinoma. The most common of these is primary retroperitoneal mucinous cystadenoma, which almost always occurs in female patients; only ten cases have been reported ...
