Purpose. To investigate the correlation between sonographic and computed tomography and pathological features of basal cell adenomas (BCAs) of the parotid gland. Methods. This retrospective study included 41 patients (43 tumors) with BCAs. The tumors were divided into three types based on their location in the parotid gland and their imaging features. The features of the tumors were analyzed. Results. Imaging manifestations and corresponding pathological results of most BCAs of the parotid glands resembled those of benign parotid gland tumors. Malignant transformation occurred in membranous BCAs and in those with extensive cribriform structures. Type-II and type-III tumors accounted for 82.93% of the total proportion. Thirteen tumors showed cystic degeneration with 30.23%, among which type-III tumors could easily develop cystic degeneration. These cystic areas might correspond to cystic degeneration or focal necrosis. Cystic change was not dependent on the tumor size. The pathological features of the tumors were correlated to their imaging manifestations. Conclusion. Most BCAs of the parotid glands have imaging manifestations similar to those of benign parotid gland tumors. BCAs with extensive cribriform structures and of the membranous type can show malignant transformation and should be treated with caution in clinical practice.

AbstractFamilial autosomal dominant cylindromatosis (FADC, turban tumour syndrome, Brooke-Spiegler-syndrome and many more, MacKusick catalogue numbers 123850, 313100) is a rare hereditary disease usually presenting in the second or third decade. With female preponderance dermal cylindromas predominantly arise in hairy areas of the body with approximately 90 per cent on the head and neck. Transformation to malignancy seems to be scarce. Although cylindromas of the skin resemble basal cell adenomas of the salivary gland, there is usually no salivary gland involvement. On the other hand, patients with basal cell adenomas of a salivary gland usually do not show dermal lesions. We report one of the rare cases of FADC combined with multiple basal cell adenomas of the parotid glands and present a review of the literature.

Slow Growing

Basal cell adenoma (BCA) is an uncommon, benign salivary tumor comprising 1-3% of salivary tumors. These tumors occur more commonly in women and patients older than 50 years of age. Patients typically present with a slow growing, well circumscribed mass. Overall BCA has a good prognosis with low rates of recurrence and malignant transformation. However, BCA membranous subtype undergoes malignant transformation at increased rates compared with the solid, tubular and trabecular forms. We present a rare case of a basal cell adenoma in a 57 year old male as well as a literature review.

Warthin's tumor is a benign lymphoepithelial neoplasm representing 10 per cent of all parotid gland tumors. Malignant transformation of a Warthin's tumor is an extremely rare event. We report a case of a patient with poorly differentiated carcinoma arising from a Warthin's tumor, as well as review the pathogenesis, histopathology, and surgical management of malignant Warthin's tumors.

Parotid glands were obtained from five adult (four male and one female) armadillos (Dasypus novemcinctus) which were perfusion-fixed. The glands were located in a position similar to that of most mammals. They extended interiorly to the anterior portion of the submandibular gland.In the light microscope, it was noted that the acini were relatively small and stained strongly positive with the periodic acid-Schiff (PAS) and alcian blue techniques, confirming the earlier results of Shackleford (1). Based on these qualities and other structural criteria, these cells have been classified as seromucous (2). The duct system was well developed. There were numerous intercalated ducts and intralobular striated ducts. The striated duct cells contained large amounts of PAS-positive substance.Thin sections revealed that the acinar cells were pyramidal in shape and contained a basally placed, slightly flattened nucleus (Fig. 1). The rough endoplasmic reticulum was also at the base of the cell.

Accessory Parotid Gland

Diagnosis of mid-cheek mass has always been a diagnostic dilemma for clinicians. The incidence of the accessory parotid gland (APG) has been well documented in the literature. However, a diverse spectrum of pathologies can arise from this accessory parotid tissue. Basal cell adenoma is a rare benign tumor that predominantly affects the parotid gland. Its occurrence in the accessory parotid gland has been documented in 9 cases till date. Surgical approaches for the management of such APG lesions have been in debate. This report documents a case of Basal Cell Adenoma arising in accessory parotid tissue in a 55-year-old woman who was treated by transoral excision. This paper also reviews previously documented cases of all APG lesions and attempts to elucidate the rationale for selecting an appropriate surgical approach.

Abstract Objective Mediastinal schwannomas are sometimes confused with other neoplasms during initial radiological studies, especially when there is a history of cancer in another area. In these cases, a more accurate analysis using computed tomography (CT) or even magnetic resonance (MRI) is required. Our study aimed to perform a retrospective analysis of the clinical and imaging features for a series of patients with mediastinal schwannomas that were confirmed by histology and immunohistochemistry. Results We found eight patients, five men and three women, with an average age of 51 years for this study. The main signs and symptoms at diagnosis were chest pain, dyspnea, cough, and dysphagia. CT showed that the tumor was located in the posterior compartment of the chest in 7/8 cases. Tumors > 10 cm were more heterogeneous and showed cystic changes. All patients underwent posterolateral thoracotomy, and radiological follow-up showed no evidence of recurrence. Histological analysis was considered the gold standard to confirm diagnosis, along with at least one neurogenic IHC marker. In conclusion, mediastinal schwannomas are benign encapsulated tumors. According to CT, schwannomas > 10 cm show cystic degeneration more frequently. Posterolateral thoracotomy allows complete resection and is considered the surgical approach of choice.
