Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is the most common cancer originating in the nasopharynx, most commonly in the postero-lateral nasopharynx or pharyngeal recess (fossa of Rosenmüller), accounting for 50% of cases. NPC occurs in children and adults.
Nasopharyngeal angiofibroma is an angiofibroma also known as juvenile nasal angiofibroma, fibromatous hamartoma, and angiofibromatous hamartoma of the nasal cavity. [3] It is a histologically benign but locally aggressive vascular tumor of the nasopharynx that arises from the superior margin of the sphenopalatine foramen and grows in the back ...
Acromegaly is a disorder that results in excess growth of certain parts of the human body. It is caused by excess growth hormone (GH) after the growth plates have closed. The initial symptom is typically enlargement of the hands and feet. [3] There may also be an enlargement of the forehead, jaw, and nose.
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
A melanocytic nevus (also known as nevocytic nevus, nevus-cell nevus and commonly as a mole) [1] [2] is usually a noncancerous condition of pigment-producing skin cells. It is a type of melanocytic tumor that contains nevus cells. [2] Some sources equate the term mole with "melanocytic nevus", [2] but there are also sources that equate the term ...
These masses are rarely superficial lesions and rarely occur in the pediatric population. [11] In a retrospective study of 266 individuals, UPS tumors ranged from 1–55 cm in greatest diameter (average 8.8 cm with 25%, 38%, and 38% having greatest diameters of 0–1, 5–9, and ≥10 cm, respectively).

Paranasal sinus and nasal cavity cancer is a type of cancer that is caused by the appearance and spread of malignant cells into the paranasal sinus and nasal cavity. The cancer most commonly occurs in people between 50 and 70 years old, and occurs twice as often in males as in females. [3] During early phases of the cancer, symptoms may include ...
A neurofibroma is a benign nerve-sheath tumor in the peripheral nervous system. In 90% of cases, they are found as stand-alone tumors ( solitary neurofibroma, solitary nerve sheath tumor [1] or sporadic neurofibroma [1] ), while the remainder are found in persons with neurofibromatosis type I (NF1), an autosomal-dominant genetically inherited ...
