ORL - TUMORS OF NOSE & PARANASAL SINUS Flashcards
NASAL ENDOSCOPY in Nasal floor to Nasopharynx
Low
NASAL ENDOSCOPY in Middle turbinate/M. Meatus to SER
Mid
NASAL ENDOSCOPY in Cribriform fossa
High
Most common intranasal mass
usually BILATERAL
NASAL POLYPOSIS
Treatment of NASAL POLYPOSIS
Functional endoscopic sinus surgery
The microscopically neoplastic epithelium is seen to grow towards underlying stroma rather than on the surface
INVERTING PAPILLOMA
The microscopically neoplastic epithelium is seen to grow towards underlying stroma rather than on the surface
INVERTING PAPILLOMA
Histologic appearance: composed exclusively or almost exclusively of hyperplastic ribbons of basement membrane-enclosed epithelium that grow endophytically into the underlying stroma
INVERTING PAPILLOMA
common in males (5:1 preponderance)
40-70 years old
associated with SCCa in 10-15% of cases
usually arise from the lateral nasal wall of nose
always UNILATERAL mass
INVERTING PAPILLOMA
Treatment of INVERTING PAPILLOMA
Medial Maxillectomy
bleeding polypus of the septum
Soft, dark red, pedunculated or sessile tumor arising from the anterior part of the nasal septum
Clinical features: recurrent epistaxis and nasal
obstruction
Capillary Hemangioma
benign lesion; Vascular malformation rather than a tumor
Histologically: vascular endothelium-lined spaces embedded in a fibrous stroma
typically affects young male adolescents
MASSIVE EPISTAXIS
JUVENILE ANGIOFIBROMA
most common carcinoma of the sinonasal area
SQUAMOUS CELL CARCINOMA
etiologic and precursor lesion issues
tumors arising in Schneiderian papillomas
tumors related to human papillomavirus (HPV)
SQUAMOUS CELL CARCINOMA
Histology: classic cribriform and cystic pattern with bland nuclear appearance
ADENOCARCINOMA
