Review
Possible complications of parotid gland surgery are numerous, just as the reasons for aneurysms of the superficial temporal artery. The occurrence of such an aneurysm as a consequence of parotidectomy, however, has so far only been published once. Here, we report of an aneurysm of the superficial temporal artery following parotid gland surgery. It presented as a pulsating mass in the preauricular region. Combining clinical examination, duplex ultrasound, and CT scan, the diagnosis was readily established and treated with a circumscribed revision at low risk and without complications.

Mammary tumors are reported in four guinea pigs and the literature is reviewed. It is concluded that mammary adenocarcinomas are second only to pulmonary adenomas as the most common epithelial tumors in the guinea pig. The sex incidence of mammary tumors is almost equal and both young and old animals are susceptible. Mammary tumors are generally locally invasive, rarely metastasize, are often quite large, and very vascular. Surgical excision of mammary tumors is possible but recurrence should be expected if the primary tumor is incompletely removed.

Salivary gland cystadenomas are cystic neoplasms with diverse architecture and cytology. Cystadenomas may have a considerable intracystic epithelial component, but an epithelial proliferation in small ducts and cysts resembling atypical ductal hyperplasia of breast has not been documented. The patient was a 68-year-old man with a slow growing right submandibular mass. He has no recurrence 13 months after resection. The tumor was polycystic and measured 3.0 x 2.5 x 2.5 cm. The epithelium of the larger cysts was composed of flat, cuboidal, columnar, and apocrine-like cells. Many of the larger cysts showed "Roman bridges", epithelial tufting, and papillae. The smaller cysts and ducts had apocrine-like cells forming secondary glandular lumens. The ductal cells were surrounded by clear myoepithelial cells. Nuclear pleomorphism and hyperchromasia was seen in the apocrine-like cells. Adjacent to the larger cysts, there was an adenomatoid proliferation of small ducts surrounded by myoepithelial cells. No mitotic activity, necrosis, or stromal invasion was identified. The ductal cells were diffusely positive for keratin 7 and androgen receptors with focal expression of keratin 19 and high-molecular weight keratin. S-100, estrogen and progesterone receptors, and BRST-2 were negative in the ductal cells. Recognition of a prominent intraductal epithelial component in cystadenomas is important to avoid a misdiagnosis of cystadenocarcinoma or low-grade salivary duct carcinoma. Cystadenomas join the list of salivary gland lesions with microscopic similarities to primary lesions of the breast.

Mucinous cystadenocarcinoma of minor salivary glands is an extremely rare entity that has only recently been described, with a few published cases in the English literature. A 42-year-old woman with a history of a surgically excised mucinous cystadenoma of the oral tongue, presented with a painful swelling in the oral tongue slowly growing for 1 month. On clinical examination, there was a firm, relatively well-circumscribed mass in the left posterior border of the mobile tongue. Subsequent MRI scan revealed a heterogeneous lesion composed of multiple cysts separated by contrast enhancing septa, in the posterior two-thirds of the left tongue. Imaging findings were similar to those of the previously resected mass, suggesting local relapse of the primary lesion. A complete surgical excision was performed and the histopathological examination revealed typical features of a low-grade mucinous cystadenocarcinoma of minor salivary glands.

We report what to our knowledge is the first case of a giant multicystic cystadenoma of the Cowper's glands. An otherwise healthy 41-year-old man presented with acute urinary retention. Physical examination showed a perineal mass. Different imaging techniques demonstrated a multicystic tumor and en bloc excision was performed. Histological evaluation showed that the tumor arised from the bulbourethral glands; immunohistochemistry proved positive staining for high molecular weight cytokeratin. CASE HYPOTHESIS: Cystic tumors in the pelvis can arise from different structures. Malignancy should be ruled out. Surgical excision can be diagnostic and curative. Future implications: When evaluating a pelvic cystic tumor, Cowper's glands cystadenoma may be a differential diagnosis and must be considered. Similar to prostate cystadenomas, en bloc excision is the optimal treatment.

INTRODUCTION
Cystadenoma is an uncommon epithelial neoplasia that arises from the salivary glands. The malignancy can affect structures such as the larynx, nasopharynx, buccal mucosa, and palate.
OBJECTIVE
To describe a case of a giant cystadenoma of the floor of the mouth treated at a public hospital in midwestern Brazil.
CASE REPORT
The patient was a 46-year-old woman with complaints of difficulties in articulating words and swallowing solid food and vocal fatigue. The progression of the disease since the initial consultation, the results of clinical examinations, and the outcome of surgery are described. Finals Comments: Cystadenoma must be considered in the differential diagnosis of cystic injuries in the floor of the mouth if the patient's symptoms are suggestive of this malignancy.

BACKGROUND Benign pleomorphic adenoma is the most common primary tumor of the salivary glands and mainly arises in the parotid gland. Warthin's tumor, or papillary cystadenoma lymphomatosum, represents <30% of benign parotid tumors. The simultaneous occurrence of multiple parotid tumors is rarely described - depending on the corresponding histology (different/identical), the time of their occurrence (synchronous/metachronous), as well as their location (unilateral/bilateral), multiple parotid tumors can be further sub-classified. CASE REPORT We describe the case of a 54-year-old female patient with progressive and painful swelling of the left parotid gland for the last 6 months. During extra-oral examination, a bulging, displaceable mass of approximately 3 cm was determined. A subsequent MRI (magnetic resonance imaging) examination revealed a multifocal lesion but failed to provide a decisive clue as to the tumor entity of the lesion, and a lateral (superficial) parotidectomy was performed. Postoperative histomorphological interpretation allowed the final pathological diagnosis of synchronous, unilateral occurrence of a pleomorphic adenoma as well as a Warthin's tumor. CONCLUSIONS This report presents a rare case of synchronous unilateral parotid tumors and supports that benign pleomorphic adenoma and Warthin's tumor are the most common associations. Since clinical examination, MRI imaging, and even cytological assessment could be misleading in the detection of synchronous ipsilateral multiple parotid gland tumors, our report also highlights the importance of timely and accurate diagnosis with histopathology to plan surgery and to exclude malignant transformation, which is a rare but important association with both types of primary salivary gland tumor.

A parameatal urethral cyst is a very rare congenital anomaly. It was first reported in two males in 1956 by Thompson and Lantin. About 50 cases have been published since then. Most of the cases which have been reported were from Japanese population and on extensive literature search, few cases were found to have been reported from India. We are reporting a case of a parameatal urethral cyst in a 7-year-old boy. Complete excision of the cyst with total removal of the epithelium is required for treatment and for prevention of recurrence.

An 88-year-old man presented with 13 apocrine cystadenomas of both lower eyelids of at least 10 years' duration. The cysts were remarkable for possessing a superior dome of either creamy or yellowish material (probably reflecting the lipid-rich decapitation secretion), surmounting a clearer fluid inferiorly, as well as for being restricted to the eyelid margins where the glands of Moll are located. Light microscopy disclosed a double-layered cuboidal cellular lining, which focally became more plump or hobnailed, exhibited apical decapitation secretion, and was occasionally thrown into papillary folds. Electron microscopy demonstrated cellular debris and segments of interrupted plasmalemmas within the cystic cavity, intercellular widenings constituting canaliculi, cytoplasmic election-dense secretory granules, flocculent mucous vacuoles, and swirls of smooth-surfaced endoplasmic reticulum. Basal cells were focally interspersed between the secretory cells and the basement membrane, and occasionally manifested spotty myofilamentary differentiation. These findings are supportive of an origin of the lesions from the secretory rather than the ductal portion of the glands of Moll. They corroborate conclusions drawn from dermatologic investigations that the cysts are an essentially proliferative process as opposed to the result of passive ductal dilatation.

Syringocystadenoma papilliferum (SCAP) is an uncommon benign adnexal tumor of the skin. It is frequently seen in association with other benign adnexal lesions, such as nevus sebaceous, apocrine nevus, tubular apocrine adenoma, apocrine hidrocystoma, apocrine cystadenoma, and clear cell syringoma. The unusual reported locations of SCAP include the head and neck, the buttock, the vulva, the scrotum, the pinna, the eyelid, the outer ear canal, the forehead, the back, the scalp, the thigh, the nipple, the axilla, and the postoperative scar. The occurrence of SCAP in the right lower abdomen is distinctly uncommon. Herein, we report an unusual case of a 41-year-old man with SCAP occurring in the right lower abdomen that did not develop malignancy, despite a long disease course and an absence of medical treatment. The clinical and histopathologic features and the differential diagnosis of SCAP are also discussed.
