Pseudoepitheliomatous keratotic and micaceous balanitis, (PKMB) is a cutaneous condition characterized by skin lesions on the glans penis that are wart-like with scaling. [1]: 657 It can present as a cutaneous horn. [2] PKMB is usually asymptomatic, with occasional irritation, burning sensation, fissuring, or maceration.
Invasive carcinoma of the penis. However, in some cases, non-dysplastic or mildly dysplastic lesions may progress directly into cancer. Examples include flat penile lesions (FPL) and condylomata acuminata. [4] In HPV negative cancers, the most common precursor lesion is lichen sclerosus (LS). [4]
Condylomata lata occurs in about one-third of secondary syphilis patients and is characterized by painless, mucosal, and warty erosions which are flat, velvety, moist and broad base in nature. They tend to develop in warm, moist sites of the genitals and perineum. These lesions hold a high accumulation of spirochetes and are highly infectious.
Balanitis circinata (also known as circinate balanitis) is a skin condition comprising a serpiginous ring-shaped dermatitis of the glans penis. [1] While circinate balanitis is one of the most common cutaneous manifestations of reactive arthritis, it can also occur independently.
The tumours (also called lesions) appear in various colours, from light tan to black. They are round or oval, feel flat or slightly elevated, like the scab from a healing wound, and range in size from very small to more than 2.5 centimetres (1 in) across. [5] They are often associated with other skin conditions, including basal cell carcinoma. [6]
The glans penis is where it is most frequently found, however it can also affect the coronal sulcus and prepuce's inner surface. Similar lesions can afflict the female genitalia, particularly the labia minora. [4] The conjunctiva, urethra, cheeks, epiglottis, and oral mucosa (gingiva, hard palate, and buccal mucosa) are additional locations. [6]
Among all primates, the human penis is the largest in girth, but is comparable to the chimpanzee penis and the penises of certain other primates in length. [13] Penis size is affected by genetics , but also by environmental factors such as fertility medications [ 14 ] [ unreliable medical source? ] and chemical/pollution exposure.
Penile cancer is due to trapped fluids under the foreskin of the penis. Uncircumcised individuals have a higher risk of penile cancer. Symptoms that may indicate penile cancer during male examination include lumps on the penis, swelling, and skin around the penis becoming thicker. Penile cancer and its grade is diagnosed by a biopsy to confirm ...
