Cavernous Hemangioma in the Parotid Gland of an Adult: A Case Report and Review of Literature.

Hemangiomas are benign vascular tumors and are classified into cavernous, capillary, and mixed, with the head and neck area as the most common site. Hemangiomas are common in pediatrics and rare in adults. Diagnosing cavernous hemangioma is challenging and requires a complete history, proper physical examination, and several radiological modalities to improve diagnostic accuracy because it is uncommon in adults. Herein, we present a case of a 66-year-old female Saudi patient with cavernous hemangioma from the diagnosis until the surgical treatment. No previous studies are reported in Saudi Arabia and this is a rare presentation of cavernous hemangioma at this age. Cavernous hemangioma in the parotid gland in adults is uncommon and is difficult to diagnose. Therefore, a thorough physical examination and several radiological modalities are required to improve diagnostic accuracy. The most effective treatment of cavernous hemangioma in adults is surgical resection.

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.

Kimura Disease: An Unusual Presentation of Parotid Mass in a Sickle Cell Disease Patient.

Kimura disease (KD) is a rare benign chronic inflammatory condition of unknown cause, usually affecting young men of the Asian race. It is frequently associated with nephrotic syndrome. In this report, we present an uncommon case of KD in a 40-year-old Saudi man with sickle cell disease who presented with swelling on the right side of his face. CT scan of the head and neck showed the asymmetrical appearance of both parotid glands: the right side appeared heterogeneously enlarged, with adjacent moderate-to-significant fat stranding. Histologically, hyperplastic changes in lymphoid tissue were observed. The patient underwent superficial parotidectomy and was then followed up till the healing of the surgical site with no complications.
