Tumors of the penis
Oncology / / April 23, 2016
There are two groups of tumors of the penis: epithelial and non-epithelial.The most common epithelial tumors of the penis, which are divided into benign and malignant.
main form of benign tumors are papillomavirus, the most frequent virus papillomavirus or genital warts.Essentially - this is not true of the tumor and epithelial proliferation psevdoopuholevye viral origin.
recognition is based on the discovery of warty, villous growths located in the inner layer of the foreskin, at least - on the glans penis.Often noted the rapid growth of viral papillomas.
Papilloma excised using electrocautery.With extensive process shows a circular excision of the prepuce.It is expedient as electrocautery.
most common form of cancer is cancer that has spread predominant in Asia, Africa and Latin America.In Europe, penile cancer occurs in approximately 1% of all malignancies in men.
predispose to the occurrence of cancer of the penis factors include phimosis, papilloma, leukoplakia.Invasive cancer can also develop
most common histological form is squamous cell carcinomas with various degrees of keratinization.
Due to the fact that often develop cancer of the penis in a closed prepuce, the beginning of the disease is asymptomatic.Joining infection and the development of inflammatory events contribute to a more rapid onset of the disease.The tumor most often located in the coronal sulcus, and then on the head, at least - on the inner layer of the foreskin.
metastatic cancer of the penis often lymphogenous way to the regional (inguinal, femoral, iliac) lymph nodes.
Often diagnosis is difficult due to the location of the tumor at the neck of the foreskin, but radical surgery must be preceded by a histological confirmation of the diagnosis.Therefore, after the incision of the foreskin produce a biopsy.
main method is a combination of surgical and radiation treatment, the nature of which must be individualized depending on the status of the primary tumor and the extent of its prevalence (disease stage).
In stage I disease used a circular excision of the prepuce, or resection of the head.In the initial stages possible radiation therapy as an independent method of treatment.In the presence of phimosis necessarily circular circumcision for the disclosure of the primary tumor.In radiation treatment of the primary tumor is most expedient blizkofokusnaya radiotherapy.
In stage II penile amputation produced within healthy tissues and Duquesne surgery (removal of the inguinal and femoral lymph nodes).
in stage III of the disease, in addition to radical removal of the tumor, it is necessary to remove not only the inguinal and femoral, and iliac lymph nodes.
In stage IV apply palliative treatment (radiotherapy, chemotherapy).Combination treatment is carried out in various embodiments.
In II and III stages of preoperative radiotherapy relieves secondary inflammatory changes, limited tumor growth, allowing you to produce more economical surgery.
application of chemotherapy in the whole complex of combined treatment of penile cancer should be considered justified.
Prognosis depends on early recognition and early treatment.The earlier diagnosed and adequately treated, the more favorable prognosis.
Among non-epithelial tumors of the penis is extremely rare, it should be noted endothelium, melanoma, sarcoma.In contrast to the epithelial form, they are often localized in the stem of the penis.Treatment is mainly surgical.Prognosis is poor.
