Benign Nasal Tumors

Benign nasal tumors include papillomas, fibromas, angiomas and angiofibromas, chondromas, osteomas, neuromas, nevi (pigmented tumors), warts.

Some authors referred to benign tumors and mucous polyps, however, these formations do not have a tumor structure and are inflammatory and allergic hyperplasia of the mucous membrane, the so-called "vocal nodules" on the vocal folds also do not belong to true tumors, they are hyperplastic nodules.

K l and n and with to and to kartin and. Typical signs of benign tumors of the nasal cavity are persistent difficulty breathing through the half of the nose in which the tumor, hyposmia or anosmia are located; minor bleeding possible. In the late stages of the disease, facial skeleton deformities, headache, displacement of eyeballs, and visual impairment are observed.

D and a g of n about z establish at an endoscopy of a nose, sounding of a tumor, palpation, radiography. The final diagnosis is verified by histological examination of a piece of the tumor.

Papillomas are usually localized in anticipation of the nose, grow relatively slowly, and often recur after removal. Given that papilloma can degenerate into cancer, its removal should be radical. In order to prevent scarring, it is advisable to perform cryotherapy on the wound surface after excision of the papilloma.

Vascular tumors of the nasal cavity (hemangiomas - capillary and cavernous, lymphangiomas) develop on the nasal septum, more often in its cartilaginous part, lower nasal concha, nasal vault. They grow slowly, usually bleed periodically, sometimes very strongly, gradually increase and can fill the nasal cavity, grow into the ethmoid labyrinth, orbit and maxillary sinus, have the appearance of a round, tuberous red-cyanotic tumor. With a large tumor, in order to clarify its boundaries, angiography of the carotid artery system is necessary.

Surgical treatment, however, one should bear in mind the possibility of massive blood loss. Before removal of the tumor, the external carotid arteries of both sides are often ligated. Small angiomas are resected with the underlying tissue or cauterized with a galvanocauter; in some cases, laser or cryotherapy is used.
Relapses are possible with non-radical excision.

The bleeding polyp in structure resembles angiofibroma, as a rule, it is localized in the cartilaginous part of the nasal septum and has a wide leg. A bleeding polyp is more common in women, especially during pregnancy and lactation. Its dimensions are usually small, but sometimes the tumor protrudes from the nose. A constant symptom is frequent bleeding, usually in small portions. Diagnosis is simple. Removal should be radical, as the remaining parts of the polyp quickly recur. With a wide leg, it is recommended to excise the polyp along with the adjacent section of the nasal septum. After removal, galvanocaustic of the edges of the wound is used.

Nasal fibroma is rare, usually localized on the eve of the nose, nasopharynx and in the area of ​​the external nose. Diagnosis is not difficult. Surgical treatment.

Osteomas of the nose and paranasal sinuses usually occur in people aged 15-25 years, grow slowly, most often localized in the walls of the frontal sinuses and ethmoid bone, rarely in the maxillary sinuses. Small osteomas often go unnoticed and are detected by chance on a radiograph of the paranasal sinuses. In the absence of cosmetic, functional or other disorders, there is no reason for immediate surgical treatment of osteoma. In this case, conduct a long observation; noticeable osteoma growth is an indication for its removal. However, sometimes small osteomas, especially on the cerebral wall of the frontal sinus, cause a persistent headache. After eliminating other causes of headache, removal of such an osteoma is indicated. In some cases, osteomas reach large sizes, can spread in the cavity of the skull, nose, into orbit, deform the facial skeleton and cause brain disorders, headache, low vision, impaired nasal breathing and smell.

Differential d and a gnostic are performed with chondroma, osteosarcoma, exostosis.

Treatment is only surgical. Osteomas of medium and large sizes, even in the absence of severe symptoms, must be completely removed.

Benign Nasal Tumors

  1. Benign tumors
    Among benign tumors of the nose and paranasal sinuses, papillomas, adenomas, vascular tumors, chondromas, and osteomas are of the greatest clinical importance. Many benign tumors show a tendency to malignancy over time. It is noted that tumors of any degree of differentiation, localized on the lateral wall of the nose, should practically be regarded as potential
  2. Benign tumors are cured by poisons
    Benign tumors consist of cells that differ from normal ones mainly only by enhanced growth. Such tumors are characterized by limited enhanced growth, are often covered with a connective tissue capsule, and do not grow into surrounding tissues. In rare cases, benign tumors reach gigantic sizes (up to 10-20 kg), but even then they do not spread throughout the body. Clinically
  3. Benign ear tumors
    Ear tumors are rare diseases. There are benign and malignant neoplasms. Benign ear tumors include papillomas, fibromas, angiomas, chondromas, osteomas, etc. Of the tumor-like formations, various cysts (atheromas, dermoids, etc.) should be noted. Benign tumors are localized mainly in the outer ear.
  4. Benign Gastric Tumors
    formed as a result of inflammatory-reactive hyperplasia of the mucosa. Tumors are fibroepithelial, less commonly fibroids, fibroids, neuromas, angiomas, lipomas, hemangiomas. Polyps - conditionally benign tumors, are single or multiple formations located mainly in the antrum
  5. Benign laryngeal tumors
    Among benign tumors of the larynx, fibromas, papillomas, and angiomas are more common. Fibroma (fibrous polyp) usually occurs at the free edge of the vocal fold at the border between the anterior and middle thirds, grows very slowly and often does not reach large sizes. It has a rounded shape, the base can be wide or in the form of legs. The histological structure of fibroma is presented
  6. Benign Ovarian Tumors
    Benign tumors of the ovaries are divided into: • epithelial; • connective tissue. Epithelial neoplasms of the ovaries usually include: • serous: o smooth-walled; o papillary. • mucinous tumors: o proper cystomas or pseudo-mucinous cystomas o pseudomyxomas. The main type of connective tissue benign tumor is ovarian fibroma.
  7. Benign Ovarian Tumors
    Benign tumors of the ovaries are divided into: • epithelial; • connective tissue. Epithelial neoplasms of the ovaries usually include: • serous: o smooth-walled; o papillary. • mucinous tumors: o proper cystomas or pseudo-mucinous cystomas o pseudomyxomas. The main type of connective tissue benign tumor is ovarian fibroma.
  8. Benign pharyngeal tumors
    Benign pharyngeal tumors include fibroma, papilloma, hairy polyp, angioma, neurinoma, neurofibroma, mixed tumors, lipoma, cysts, pharyngeal goiter. More often than others, papillomas and fibromas on the leg are found. Papillomas are usually soft, located on the soft palate and palatine arches, are small in size and, as a rule, bother the patients a little. In some cases, papillomas come from
  9. Benign liver tumors
    Epidemiology. They occur at any age, mainly in women. In the structure of liver tumors, benign tumors make up 34%. Etiology: • intake of oral hormonal contraceptives containing estrogen; • pregnancy, childbirth; • ovarian tumors; • hormonal changes in children. Pathological anatomy: Hamartomas - nodular subcapsular
  10. Benign Neurogenic Tumors of the Ear
    Benign neurogenic ear tumors include a glomus tumor and auditory nerve neuroma. Glomus tumor (chemodectoma, nonchromaffin middle ear paraganglioma or glomerulocytoma) ranks first in frequency among benign tumors of the middle ear. It develops from glomuses (glomeruli), often found formations along the tympanic nerve, ear branch
  11. Benign tumors
    Fibrous tissue. 1. Fibroma - can be localized in any organ where there is connective tissue, but more often in the skin, mammary gland or in the ovaries. Depending on the predominance of cells or fibers in the tumor, fibroma is divided into a) hard and b) soft. 2. Dermatofibroma [histiocytoma) is often localized on the skin of the feet, in addition to fibers and histiocytes, the presence of giant multinuclear cells is characteristic in the tumor
  12. Benign laryngeal tumors
    Laryngeal fibroma is in first place among all benign tumors of the larynx. It occurs equally often in men and women aged 20-50 years, in children is extremely rare. Usually they grow on the free edge along the upper surface of the vocal fold, have a dark cherry (sometimes lighter) color, as a rule it is single, mobile (Fig. 4.18). Its size is from lentil grains to peas. Complaints
    In the nasal cavity and paranasal sinuses, as in other ENT organs, there are benign and malignant neoplasms, very diverse in morphological structure and clinical manifestation. A distinct border is often impossible to draw with many benign and malignant tumors. Modern classifications of tumors, including the nose and paranasal sinuses, are bulky and
