Very rarely we will find benign salivary gland tumor in nasal cavity. Pleomorphic adenoma is still the most common pathological variety either in major or minor salivary gland tumors. In the nasal cavity, even though most of the accessory salivary glands are present in the lateral wall of nose, nasal septum remains the most common site of origin. <strong>Case Report:</strong> A 40-year-old female presented with right-sided nasal obstruction and epistaxis. CT scan of Nose and Paranasal sinuses found a lesion involving the anterior third of the right nasal cavity. The patient underwent complete surgical resection of the tumor via an endonasal approach. Histological examination found a mixed cellular component (epithelial and myoepithelial) and mesenchymatous tissue with chondromyxoid stroma, enabling diagnosis of a typical pleomorphic adenoma. <strong>Conclusion:</strong> Pleomorphic adenoma is the most common salivary gland tumor but rare to find in the nasal cavity with only few cases reported in the literature. Although benign, the risk of local recurrence, malignant transformation and metastasis requires close long-term follow-up.展开更多

Also seen mass in the left ear along with facial weakness and diplopia. After histopathologic evaluation, it was diagnosed as embryonal rhabdomyosarcoma. <strong>Conclusion:</strong> Rhabdomyosarcoma should be kept in mind as a differential diagnosis in all children presenting with otitis media with mastoiditis. Biopsy should be considered who are not responding to medications and those worsening condition.展开更多
