Primary Ewing Sarcoma in the Sphenoidal Sinus: A Case Report.

Ewing's sarcoma (EWS) is a rare malignant bone tumor that primarily affects children and young adults. While it typically affects long bones, it can occur in the head and neck region, including the paranasal sinuses in rare cases. We present a challenging case of a 45-year-old female diagnosed with an EWS of the sphenoidal and the right nasal fossa. A subtotal removal of the mass was performed on the patient followed by combined adjuvant radiotherapy and chemotherapy. Due to its rarity, the diagnosis and management of EWS in the paranasal sinuses are challenging.

Oropharyngeal Lipoma: A Rare Case of Dysphagia.

Lipomas are benign and slow-growing neoplasms that typically develop in the subcutaneous tissue. They rarely occur in the upper aerodigestive tract. Oropharyngeal lipomas are rare. They represent 0.5% of all neoplasms of the head and neck. We present a case of a 43-year-old female with a polypoid mass in the base of the left palatine tonsil. The patient underwent a left tonsillectomy and a resection of the mass. The pathological diagnosis was tonsillar lipoma. We describe the clinical characteristics and the management of this rare case. Palatine tonsillar lipoma is a rare benign tumor with an unusual recurrence rate, and an excellent prognosis.

An intramuscular hemangioma of the semispinalis muscle: A case report.

Intramuscular hemangiomas are uncommon benign endotheliomas that typically occur in the trunk and limbs. Head and neck involvement is relatively infrequent, with the masseter muscle being the most commonly affected site. We present a rare case of intramuscular hemangiomas arising from the semispinalis muscle. A 31-year-old male presented with a painless swelling in the left upper neck region, gradually increasing in size over the past year. Imaging studies revealed a well-defined mass originating from the semispinalis muscle. Surgical excision was performed successfully, and histological examination confirmed the diagnosis of a mixed intramuscular hemangioma. The patient remained recurrence-free during the 2-year follow-up period. Intramuscular hemangiomas in the posterior neck muscles are rare, with only a few reported cases. Wide surgical resection with control of feeding vessels is the optimal treatment, and follow-up is recommended to monitor for local recurrence. This case report highlights the clinical presentation, diagnostic challenges, and successful surgical management of intramuscular hemangiomas in a unique location, emphasizing the importance of accurate diagnosis and appropriate treatment of this rare tumor.
