Malignant mesenchymal tumors of oropharyngeal mucosa are rare. Those with fibroblastic and histiocytic differentiation in the skin are called atypical fibroxanthoma (AFX) and in the soft tissue undifferentiated pleomorphic sarcoma (UPS). Here we present a case of an older patient with a history of multiple basal cell carcinomas and recently with a rapidly growing polypoid lesion in the mucosa of posterior oropharyngeal wall with AFX/UPS morphology. The differential diagnosis, histological pitfalls of this poorly characterized mesenchymal lesions, and the challenges associated with treatment are discussed.

Abstract Background Possible factors for cell atypia in nasal mucosa include noxious chemicals: ammonia, formaldehyde and heavy metals. Aims Case presentation of a nasal polyp with epithelial dysplasia in a worker exposed to nickel and copper salt dust. Case report A 27-year-old man complained of impaired nasal breathing and mild right-sided epistaxis. He was exposed to copper and nickel salt dust for 6 years. Clinical examination showed a polypoid lesion arising from the right middle turbinate. Histopathological examination of the excised lesion showed high-grade epithelial dysplasia. Duration of exposure and concentration of heavy metals in serum suggest the biological plausibility of exposure to these factors and development of epithelial dysplasia in the nasal mucosa. Conclusion Epithelial dysplasia may occasionally be noted in inflammatory nasal polyps, especially in workers exposed to heavy metals.

Submucosal Mass

Rosai-Dorfman disease (RDD) was formerly known as “sinus histiocytosis with massive lymphadenopathy”, and cases involving the gastrointestinal tract are rare. We present a case of pure extranodal RDD, resected as a polypoid lesion in colonoscopic study. The patient was a 62-year old woman with a history of sigmoidectomy for unexplained peritonitis. Microscopic study of the polypoid lesion showed the submucosal mass with histological and immunological features of RDD. The whole body computed tomography revealed neither lymphadenopathy nor tumor-like mass.

Upj Obstruction

Giant fibroepithelial polyp is a rare cause of ureteric/ureteropelvic junction (UPJ) obstruction. We report a rare case of giant fibroepithelial polyp in a 32-year-old woman involving the whole length of the ureter, reaching up to the UPJ which was clinically and radiologically considered to be urothelial carcinoma. Frozen section showed a polypoid lesion lined by urothelium with no evidence of dysplasia or malignancy. Subsequently, nephroureterectomy was done as there was marked renal hydronephrosis and it was impossible to separate the polyp from the wall of the ureter. Histopathological examination and immunohistochemistry confirmed the diagnosis of giant fibroepithelial polyp, ruling out malignancy.
