Inverted papilloma is an uncommon primary nasal. Despite its benign nature, this tumor represents three typical characteristics: a high propensity of recurrence, local aggressiveness and association with malignancy. Inverted papilloma can reduce the patient’s quality of life due to compromised nasal function, extension to orbit and brain even in absence of malignancy. We are presenting a case o...
Inverted nasal papilloma is a unique neoplasm characterised by a tendency to recur following excision, an association with malignancy and an ability to destroy bone. The coexistence with nasal polyps (not always sent for histology), the lack of a universally accepted staging system and the fact that most data on Inverted papilloma come from tertiary centres (selected cases probably the most agg...
Even though endoscopic removal of inverted papillomas has gained popularity, many studies advocate supplementary external approaches. The impact of including the current surgical staging system into the pre-operative clinical and radiological assessment has not been systematically evaluated. We present our experience with total endoscopic management of inverted papillomas and compare the accura...
By excising after varying intervals the site of inoculation of the rabbit skin injected intracutaneously with the Shope papilloma virus and titrating its virus content, it has been shown that demonstrable active virus disappears from the skin within approximately 24 hours. The disappearance of most of the virus within such a short time as 15 to 60 minutes makes a transportation of virus from th...
A case of a lobulated polypoid tumor of the ureter showing histologically high grade malignancy is reported. Such a tumor is rare in the bladder, and to date none have been documented in the ureter. This tumor is probably the most malignant urothelial tumor of the inverted type in the urinary tract, including inverted papilloma.
Unilateral nasal masses are considered suspicious for proliferative diseases. Several tools are routinely used to investigate unilateral lesions such as imaging and nasal biopsy. This study investigated the usefulness of nasal biopsy in predicting the actual nature of unilateral lesions. Preoperative nasal biopsy pathological results were compared with the final pathology obtained during an ope...
INTRODUCTION Inverted papillomas are benign sinonasal lesions that arise primarily from the lateral nasal wall which are characterized by their tendency to recur and propensity to be associated with malignancy. The aim of this work is to analyze our experience in the treatment of these lesions, especially through the endoscopic approach. MATERIAL AND METHOD We present 61 cases of sinonasal in...
