Abstract Background: To report a case of phosphaturic mesenchymal tumour of nose highlighting the diagnostic challenges involved. Case presentation: A 50 years old male who had history of multiple lower limb fractures presented with epistaxis and a vascular mass in left nasal cavity that enhanced on contrast-enhanced computed tomography (CECT), and MRI. The patient had raised serum phosphate and PTH levels. The tumour was excised endoscopically and the patient recovered completely. Conclusion:Malignant Phosphaturic mesenchymal tumors (PMTs), although rare, may behave aggressively, recur and metastasize. They are difficult to diagnose and should be kept in differential diagnosis of nasal tumours who present with osteomalacia.

Objective: To present a rare case of endoscopic removal of maxillary Odontogenic Keratocyst in a paediatric patient.

Chondroid neoplasm of parotid gland is extremely rare. Only a few cases of extraskeletal chondroma and one case of chondrosarcoma of parotid gland have been reported in the literature. The cytological features of parotid gland chondroma are not well documented. A 61-year female patient presented with a slow growing left preauricular mass for past 6 years. Computer tomography scan showed a well circumscribed mass in the superficial lobe of left parotid gland. Fine needle aspiration cytology (FNAC) showed uniform chondrocytes embedded in a chondroid matrix, and was diagnosed as pleomorphic adenoma. Histological examination of the excised specimen showed a benign cartilaginous tumor, consistent with chondroma. There was no epithelial or myoepithelial component on extensive search. Chondroma is an extremely rare tumor of parotid gland and can be misdiagnosed as pleomorphic adenoma on cytology examination. However, absence of epithelial and myoepithelial component can give a clue toward a pure chondroid neoplasm. This report highlights the diagnostic features of chondroma of parotid gland and its diagnostic pitfalls in FNAC.
