Bowenoid Papulosis is a rare, sexually transmitted disorder thought to be caused by human papillomavirus type 16. This disorder is characterized by lesions that are found on the genitals of males and females. The lesions are reddish brown or violet in color, small, solid, raised and sometimes velvety.
Bowenoid Papulosis is a rare sexually transmitted infection that is characterized by lesions that are typically found on the genitals. These lesions may last from two weeks to several years. Females may be affected inside the vagina, on the clitoris, groin folds, labia major, labia minor and/or anus. Males may be affected on the glans, shaft and/or foreskin of the penis as well as the anus. The lesions found in Bowenoid Papulosis are usually reddish brown or violet in color, small, solid, smooth, raised and velvety. The lesions on females are usually darker than the lesions on males.
Many patients with Bowenoid Papulosis often have other types of viral infections that precede this condition. Herpes simplex, human papallomavirus, viral warts, and HIV infection have been found in some patients with this disorder. When viewed under a microscope the Bowenoid Papulosis tissue structure looks like pre-invasive squamous-cell carcinoma (a form of cancer cells). In some cases Bowenoid Papulosis has become malignant.
Bowenoid Papulosis is a sexually transmitted disorder thought to be caused by human papillomavirus type 16. Other viruses as well as a suppressed immune system may also play a role in contracting Bowenoid Papulosis.
Bowenoid Papulosis affects sexually active males (average age, 30) and females (average age, 32) equally. However, in the literature, Bowenoid Papulosis patients range in age from 3 to 80. It has recently been appearing in increasing numbers worldwide.
Symptoms of the following disorders can be similar to those of Bowenoid Papulosis. Comparisons may be useful for a differential diagnosis:
Bowen's Disease is characterized by a precancerous, slow growing skin malignancy. The major symptom is a red-brown, scaly or crusted patch on the skin which resembles psoriasis or dermatitis. It may occur on any part of the skin or in the mucous membranes. (For more information on this disorder, choose "Bowen's Disease" as your search term in the Rare Disease Database.)
Condyloma is a common infectious venereal disease that is caused by the human papillomavirus (HPV) and usually transmitted by direct sexual contact. The warts found in this disorder are small, soft, moist, pink or red elevations on the skin or mucous membranes of the genitals, mouth, anus or rectum. Typically the warts form in clusters. (For more information on this disorder, choose "Condyloma" as your search term in the Rare Disease Database.)
Lichen Planus is a recurrent, itchy, inflammatory eruption of the skin which is characterized by small, separate, angular spots that may grow together forming rough scaly patches. It is often accompanied by oral lesions. Women are most commonly affected by this disorder. The lesions are most commonly found on the joint surfaces of the wrists and on the legs, trunk, glands, penis and mucous membrane of the mouth and vagina. (For more information on this disorder, choose "Lichen Planus" as your search term in the Rare Disease Database.)
Patients with Bowenoid Papulosis should be monitored carefully. In some cases Bowenoid Papulosis may heal spontaneously (without treatment). Sexual activity should be limited in order to avoid infecting other people during the contagious stages of this disorder.
Electrosurgery, cryosurgery (surgery in which the tissue is frozen with liquid nitrogen), and/or lazer surgery may be used to remove the lesions when necessary.
In some milder cases the use of 5-Fluorouracil (a chemical that prevents cell division) in the form of a topical cream has been successful.
