ABSTRACT
Solitary fibrous tumors of the nasal cavity and paranasal sinuses are rarely encountered in clinical practice. These are unusual mesenchymal tumours initially described as primary spindle-cell neoplasms. Such tumours may manifest in pleural and extrapleural sites such as the liver, parapharyngeal space, sublingual and parotid glands, and thyroid but are seldom described in the nose and paranasal sinus region. Erosion of adjacent structures may occur, but the tumour itself does not metastasise. A young patient presented with a progressive unilateral nasal mass. The initial nasal biopsy reported it as a benign inflammatory nasal polyp. Imaging revealed a large, locally expansile mass within the right nasal cavity displacing the nasal septum. The patient underwent excision of the tumour and the diagnosis of solitary fibrous tumour was confirmed by immunohistochemistry staining. This case is intended to highlight the diagnosis and management of this rare tumour.
ABSTRACT
A parotid lesion with facial nerve involvement almost always indicates malignancy. Facial nerve palsy as a complication of parotid abscess is extremely rare. The postulated mechanisms include ischaemic neuropathy secondary to the compression of the facial nerve by the parotid swelling, local toxic effect and perineuritis from the inflammatory process. Here, we present our experience in managing a case of facial nerve palsy due to a parotid abscess in an otherwise healthy 44-year-old female. The abscess was drained surgically and the facial nerve function returned to normal at two months. Histopathological examination of the parotid tissue showed no features of malignancy. The severity of facial nerve impairment varied from grade II to total palsy. The mainstay of treatment of a parotid abscess is surgical drainage along with medical therapy including broad-spectrum antibiotics, adequate hydration and sialogogues.
