Basal Cell Adenoma of the Parotid Gland: A Rare Disease Entity.

Neoplasms of the salivary glands are of rare incidence, have a vague presentation, and follow a complex long-term clinical course. Both minor and major salivary glands have been implicated in dysplastic transformation, with parotid gland tumors being the most notable. Most of these tumors are benign in nature and are typically diagnosed and classified based on their histopathological presentation. In this report, we exhibit a rare case of basal cell adenomas (BCA), localized to the right parotid gland, in a 69-year-old male patient. Volume acquisition computed tomography (CT) imaging of the region was obtained with and without contrast, with relative reconstruction in both the coronal and axial planes. A soft tissue mass of 5 cm in diameter was detected in the superficial lobe of the right parotid gland. Fine needle aspiration (FNA) with ultrasound guidance revealed a population of basaloid cells that is monomorphic with minimal nuclear atypia and scattered fibrillary matrix. Thereafter, the patient was treated with partial excision of the right parotid gland under general anesthesia, and the post-operative pathology report confirmed the diagnosis of basal cell adenoma. The patient was doing well post-operatively with no complaints and maintained routine clinic follow-ups.

Basal Cell Adenoma of the Minor Salivary Glands in the Buccal Mucosa: A Rare Entity Arising in an Unusual Location.

One of the rare tumors of the salivary gland is known as basal cell adenoma (BCA). Only a small percentage of salivary gland tumors affect the minor salivary gland of the oral cavity while the majority are found in the parotid gland. We present a rare case of BCA involving the left buccal mucosa of a 45-year-old female. Magnetic resonance imaging (MRI) showed well defined solid mass measuring 1.9 x 1.5 cm in the left buccal space inseparable from the buccinator muscle. The T2-weighted image demonstrates a hyperintense signal post-contrast. Ultrasound-guided fine needle aspiration cytology revealed cellular basaloid neoplasm of uncertain malignant potential. Thereafter excision of the mass was performed through a transoral approach under general anesthesia. Histopathology of the mass showed encapsulated basal cell neoplasm in favor of BCA. The patient was doing well after the surgery and has intact facial nerve and adjacent nerves such as the auriculotemporal nerve and great auricular nerve with no complications then she kept on routine clinic follow-ups, and the surgical site recovered successfully. Therefore, we conclude that MRI and biopsy provide useful information to differentiate between benign adenoma and malignant adenocarcinoma. BCA should be considered in a differential diagnosis of an isolated neck mass. Surgical excision demonstrates an excellent prognosis.

Excising Parotid Benign Mass With a Minimal Incision.

We report a case of a 30-year-old man who presented with a one-year history of a right-sided parotid mass that was asymptomatic but slowly increasing in size. On examination, there was a 2 × 2 cm superficial, soft, painless, and mobile mass in the right parotid region. Computed tomography revealed a benign mass in the right parotid tail measuring 2 × 3 cm, and a fine needle aspiration biopsy revealed a Warthin's tumor. The patient was managed surgically using a new approach that involved complete excision of the mass via minimal cosmetic incision parotidectomy. Parotidectomy was performed using an incision that only involved the pre- and postauricular areas over the sulcus without any extensions, and the operation proceeded smoothly without any complications. The patient was discharged without postoperative complications.

Lingual schwannoma in an adolescent boy: A case report.

Oral cavity schwannoma is still considered a rare entity in the head and neck region. Schwannoma is a benign encapsulated nerve sheath tumour that originate from Schwann cells with an approximate incidence of 1% in the oral cavity. The tongue is the most common location among oral cavity tumours. We report a rare case of tongue schwannoma in 12-year-old boy who presented to our centre complaining of swelling of the tongue, which had increased in size and interfered with his speech in 2018; he had been previously asymptomatic since birth. A diagnosis was established based on the following imaging studies: computed tomography (CT) and magnetic resonance imaging (MRI). He underwent simple transoral excision of the ventral tongue mass under general anaesthesia with no complications, and the final pathological result confirmed the diagnosis of schwannoma.
