Erythriplasia of Queyrat (EQ)

**THISONESFORYOU** · 10-10-2009

Erythroplasia of Queyrat (EQ) originally was described by Tarnovsky in 1891 and subsequently was appreciated as a penile disease by Fournier and Darier in 1893. More intensive studies by Queyrat in 1911 allowed this condition to be accepted as a distinct entity. He described erythroplasia of the glans penis and concluded that the disease represented a precancerous process.

EQ arises from the squamous epithelial cells of the glans penis or inner lining of the prepuce. It is seen almost exclusively in uncircumcised men and represents an in situ form of squamous cell carcinoma. Progression to invasive carcinoma may occur after a variable period of time.

EQ most often occurs in uncircumcised men. Multiple factors have been implicated as causative agents in this process.

Chronic irritation, inflammation, and infection appear to be the common links. A recent case report described a patient with coexistent Zoon balanitis.2
Urine, smegma, or poor hygiene can cause chronic irritation of the area.
Other physical factors, such as heat, friction, and trauma, also have been implicated.
Chronic infections, such as herpes simplex and human papillomavirus,3 are other considerations.
Immunosuppression from allogenic organ transplantation may contribute to increased overall incidence and invasive disease in affected patients.
Consider a broad differential diagnosis with cutaneous penile lesions. All types of inflammatory, infectious, and neoplastic processes can occur in this area. A systematic approach is crucial.

Don't know what to make of this, but it doesn't seem a positive post.

A good argument for mass circumcism.

I thought (EQ) was meant to refer to Erection Quality. At first i thought this post was from a troll wind up merchant ( so many long scientific words ) now I am unsure

A good argument for hygiene and safe sex. And outhere EQ on this board does stand for erection quality.
