Background. Angiofibroma is a benign tumor, consisting of fibrous tissue with varying degrees of vascularity, characterized by proliferation of stellate and spindle cells around the blood vessels. It most commonly arises from the nasopharynx, although it may rarely arise in extranasopharyngeal sites. Case Report. A 46-year-old male presented with left side nasal obstruction and epistaxis for on...

background and objective: nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. cytokeratins (ck) are intermediate filament proteins that provide mechanical support in epithelial cells. the purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. mate...

Malignant schwannoma is an extremely rare tumor and the risk of malignant schwannoma increases in patients with von Recklinghausen's disease. Recently, we encountered a case of solitary malignant schwannoma in the choana and posterior nasal septum. Malignant schwannoma has not been previously reported in these locations. A 53-year-old man, who was immunologically healthy and showed no abnormal ...

Pleomorphic adenomas are the most common benign tumor of the major salivary glands. In addition, they may also occur in the minor salivary glands of the hard and soft palate. Nasal masses are often due to antrochoanal or ethmoidal polyps or angiofibromas or haemangiomas or papillomas. Intranasal pleomorphic adenomas are very unusual and may be misdiagnosed because they have greater myoepithelia...

Development of a cystic mass on the nasal dorsum is a very rare complication of aesthetic rhinoplasty. Most reported cases are of mucous cyst and entrapment of the nasal mucosa in the subcutaneous space due to traumatic surgical technique has been suggested as a presumptive pathogenesis. Here, we report a case of dorsal nasal cyst that had a different pathogenesis for cyst formation. A 58-yr-ol...

Neurofibromas are benign peripheral nerve sheath tumors which originate from Schwann cells. They are known to occur in extremities as a local manifestation of Von Recklinghausen’s disease i.e. type 1 neurofibromatosis, but isolated neurofibroma occurring in the nasal cavity is a rare entity. Here we report one such case in a 60 year old lady who, presented to us with complaints of difficulty in...

Carcinosarcoma is a highly malignant tumour exhibiting histological components of both carcinomatous and sarcomatoid elements. Carcinosarcoma is extremely rare in the sinonasal cavity. Due to the rarity and clinical diversity, these neoplasms are often misdiagnosed and pose a challenge in their management. Here we report a 44-year-old man with epistaxis and progressive symptoms of nasal obstru...
