How does laryngeal papilloma examine oneself?

summary

Some tumors can be self-examination, laryngeal papilloma is a benign epithelial tumor occurred in esophageal stratified epithelium, most of which are lobulated, sessile or sub pedicled. The color is the same as the esophagus or slightly faded, close to the blood vessels in the center of the papillary structure. Let me share with you how to self-examine laryngeal papilloma?.

How does laryngeal papilloma examine oneself?

First, the etiology of papilloma is unknown, accompanied by the growth of inflammation, there are also reports related to papilloma "virus". The gross appearance should be differentiated from 0-iia stratified epithelial carcinoma and verrucous carcinoma, but the diagnosis can be made based on the above characteristics.

Second, benign laryngeal tumors are rare, among which squamous cell papilloma and leiomyoma are relatively common, granulosa cell tumor is the most common in the digestive tract. Squamous cell carcinoma is the most common malignant tumor. According to the degree of cell differentiation, it can be divided into three grades: well differentiated, moderately differentiated and poorly differentiated. Well differentiated squamous cell carcinoma has small atypia and obvious formation of keratinizing beads (cancer beads); The dysplasia of poorly differentiated squamous cell carcinoma is obvious, and the keratoglobus is rare; The morphology of moderately differentiated squamous cell carcinoma is between the former two.

Third: HPV, or human papillomavirus, is the general term of a group of viruses. At present, scientists have found more than 100 kinds of viruses, of which about 30 types can cause genital infection in men and women. There are 13 high-risk viruses that may cause cervical cancer. They are divided into low-risk HPV and high-risk HPV according to the risk of HPV and tumor. The low-risk HPV includes HPV6, 11, 42, 43 and 44, It often causes benign lesions such as condyloma of external genitalia, including low-grade cervical intraepithelial lesions (CIN I). High risk HPV types include HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, which are associated with cervical cancer and high-grade cervical intraepithelial lesions (CIN II / III), especially HPV16 and 18. The most common types of HPV in genital tract infection were 16,18,6,11. HPV6 and HPV11 often infect vulva, anus, vagina and other parts, which belong to low-risk types. Condyloma or low-grade cervical intraepithelial lesions are common in women, and are not significantly associated with cervical invasive cancer; Type 16 and 18 were high risk.

matters needing attention

First of all, we all know that esophageal papilloma is summarized as benign epithelial tumor. It has been reported that papilloma is caused by virus, which is HPV. And this virus type 16.18 is the primary factor of cervical cancer（ This is one of them; Let's talk about the throat. Throat papilloma rarely canceration, but also have! Throat and esophagus are squamous epithelium, if the throat has papilloma canceration, then esophageal papilloma will also have canceration probability! This has to be integrated（ It's not that esophageal papilloma has no canceration, it's just that we haven't met it. Its canceration is a real existence!
