Mucinous Cystadenomas

Urachal mucinous neoplasms are rare and include both villousadenomas and invasive adenocarcinomas. These mucinous tumoursshould be completely excised as they can demonstrate aggressiveclinical behaviour, including the development of pseudomyxomaperitonei. We describe a 70-year-old woman who presented witha lower abdominal mass and received a diagnosis of a rare, complexurachal mucinous cystadenoma of undetermined malignant potential.This tumour demonstrated extensive mucin extravasation intoperivesical soft tissue, but was not associated with pseudomyxomaperitonei or any malignancy. Rarely described in the English literature,mucinous cystadenomas of the urachus should be treatedsimilarly to their villous adenoma counterparts: with complete surgicalexcision to prevent local tumour recurrences.

Mucinous Cystadenomas

Epithelial ovarian tumours are rare in the adolescent age group, accounting for less than 15% of overall ovarian malignancy. Of this, one-fourth of them are mucinous in nature. Mucinous cystadenomas, being precursors of borderline and invasive ovarian tumours, can reach to size as large as 15-30 cm in diameter without having malignant potential. Also, intraoperative management of such large abdominal mass can be challenging. We present a case of a giant unilateral 12 kg mucinous cystadenoma in a 13-year-old young girl, that grew over a period of 1 year. She underwent left salpingo-oophorectomy after decompression of the mass without any complications.

Primary Retroperitoneal

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 case reports have been published. PRMTs are divided into mucinous cystadenomas, mucinous borderline tumors of low malignant potential, and mucinous carcinoma. These tumors have malignant potential so resection is indicated and in some cases adjuvant chemotherapy and/or surveillance imaging.

Mucinous Cystadenomas

Abstract A mucinous cystadenoma of the paratestis arising from an unequivocal oviduct-like structure in an 18-year-old man is reported. Mucinous cystadenomas of the testis and paratestis are extremely rare benign tumors of controversial origin. The diagnosis may be challenging and is of clinical importance because these lesions may mimic a teratoma, and teratomas in postpubertal males carry a malignant potential regardless of the degree of maturation. A few case reports and reviews of testicular and paratesticular mucinous neoplasms resembling ovarian tumors have suggested the possibility of a müllerian origin of these tumors. However, no histologic evidence has been found to support such a histogenesis. The current case demonstrates a clear transition from müllerian-type tubal epithelium to intestinal-type mucinous epithelium. This finding, in conjunction with immunophenotypic studies, strongly supports a derivation from a paratesticular müllerian remnant. To our knowledge this represents the first substantial evidence that, in at least some cases, mucinous cystadenomas of the testis and paratestis are of müllerian derivation.

Mucinous Tumours

Testicular epithelial mucinous tumours are an extremely rare, butinteresting form of testicular neoplasm. We reviewed the medicalliterature using PubMed search terms: testis, mucinous cystadenoma,mucinous cystadenocarcinoma, neoplasms and testicularneoplasms. We describe a case from our institution and provide areview of the literature. Only 11 previously reported cases of mucinoustesticular tumours have been reported in the English literature.The natural history of these tumours is poorly understood, due totheir rarity, but it appears that, like their ovarian counterparts, theyhave an excellent prognosis. Exclusion of metastasis is an importantpoint for the urologist when encountering a mucinous testiculartumour, as metastatic cystic lesions may mimic a primary mucinoustumour. We describe a case of ossified testicular mucinoustumour of low malignant potential. Such tumours are commonin the ovary, but arise very rarely in the testicle. The clinical andhistological features of this tumour are presented, and previouslyreported cases are reviewed to highlight important clinical features.

Laparoscopic Cystectomy

Mucinous cystadenoma arises from the totipotent surface epithelium of the ovary. Its association with Brenner tumor suggests its origin as mucinous metaplasia of the epithelioid cells. The chance of malignancy is 5–10 percent. Patients usually present with abruptly increasing abdominal mass. Cystectomy is the management of choice in these cases. It was managed by laparoscopy.
