Lacrimal sac rhinosporidiosis
Rhinosporidiosis is caused by the organism Rhinosporidium seeberi. It is a rare aquatic protistan parasite. Though more prevalent in Asiatic regions, cases have also been reported in European countries. In India, it mostly affects the southern part. Rhinosporidium seeberi most commonly affects the mucous membranes, but can also affect other structures including the larynx, trachea, skin, genitalia, lungs and rectum. The typical presentation is that of a pinkish mass which bleeds profusely. Isolated lacrimal sac rhinosporidiosis is very rare. Computed tomography scans and magnetic resonance imaging are helpful in diagnosis, but histopathological study along with Gomori methenamine silver, periodic acid-Schiff, and potassium chloride are required for confirmation. Its mainstay of treatment is surgery. Prognosis is excellent, but recurrence is not unusua
Parapharyngeal space schwannoma of hypoglossal nerve
Parapharyngeal schwannomas are rare benign neoplasms located in a difficult anatomical region. Most of them are asymptomatic and some presents late. Neurological deficit is a late finding, and it occurs only when the lesion is very large and compresses contiguous structures. Computed tomography (CT) guided fine needle aspiration cytology along with preoperative CT and magnetic resonance imaging can detect and diagnose it correctly and helps in proper planning and management. Total surgical excision is the treatment of choice. The approach is different as per the site, but trans-cervical approach is preferred. Recurrence is rare after complete excision. We are presenting a very rare parapharyngeal schwannoma arising from the hypoglossal nerve that was excised by trans-cervical approach without any complications and less morbidity as compared to other described approaches
