Two cases of inverted papilloma of the urinary bladder are reported. The benign character of these unusual lesions is confirmed, and the importance of their recognition indicated.

Rhinosporidiosis is a chronic granulomatous disease of mucous membranes and is endemic in Southern India and Sri Lanka, though there are infrequent reports of the disease elsewhere in the world with Rhinosporidium seeberi identified as aetiological agent. Sino nasal Inverted papilloma constitutes only 0.5-4% of all nasal tumours and may be associated with human papilloma virus, chronic inflamma...

Oncocytic Schneiderian papilloma, fungiform papilloma, and inverted papilloma are 3 morphologically separate tumors arising from the Schneiderian membrane. Oncocytic Schneiderian papillomas comprise about 3 approximately 5% of this entity. Old-aged group predominates. No sex predilection is noted. Multi-layered eosinophilic epithelium characterizes this kind of tumor. Exophytic and inverted gro...

Inverted papillomas (IPs), although histologically benign, are aggressive lesions that may recur after excision. They usually present as unilateral firm, bulky, red and vascular masses. The objective of this case series is to discuss the surgical treatment options for IPs and to review the literature with a special emphasis on our experience with endoscopic medial maxillectomy. A retrospective ...

Inverted papilloma is the most common benign tumor of nose and paranasal sinuses arising from lateral nasal wall and middle meatus. Histologically these tumors are composed of epithelial nests that are inverted, exophytic and cylindrical. Here we describe a clinical case of nasal cylindrical cell papilloma, which was treated by endoscopic excision.

The inverted papilloma is an uncommon unilateral nasosinusal benign tumor. The clinical picture presents nonspecific signs and symptoms, such as unilateral nasal obstruction, anosmia and headache. The diagnosis is established by anamnesis, physical exam, computed tomography and magnetic resonance imaging. Treatment is essentially surgical. This report has the objective of presenting an uncommon...

Urothelial inverted papilloma is usually a solitary lesion with rare recurrences. Its behaviour is unclear, its potential for recurrence or progression is not well-known. We present a case of inverted papilloma of the bladder with recurrence in prostatic urethra after four years of follow-up. We review etiology, clinical presentation, diagnose, treatment and the present discussion about its mal...

BACKGROUND Our aim was to review our management of inverted papilloma (IP), perform a recurrence analysis, and review the literature. METHODS A retrospective analysis of 247 patients treated for an IP. Patients were grouped according to surgical approach, tumor presentation (primary, residual and recurrence) and Krouse-stage. RESULTS Recurrence was observed in 20.3%, 28.6% and 35.1% (p = 0....

We describe two cases of nasal inverted papilloma who had different management modalities. Although both were essentially of the same pathology, one underwent endoscopic excision while the other was treated with the more popular lateral rhinotomy and medial maxillectomy. We wish to highlight the different modalities of treatment available for inverted papilloma and a review of published results.
