Urticaria factitia is a medical condition typically caused by pressure or trauma to the skin, resulting in hives. The pronunciation of this term is [ərˌtɪkəˈriːə fækˈtɪʃə], with the emphasis on the second and fifth syllables. The word 'urticaria' derived from the Latin word for "nettle", while 'factitia' means "artificially produced". The word's spelling may be difficult to remember at first, but it becomes easier with practice.
Urticaria factitia, also known as dermatographism or skin writing, is a type of urticaria, which refers to a condition characterized by the development of itchy, raised welts or hives on the skin. However, urticaria factitia is unique in that it is triggered by physical stimuli or pressure applied to the skin. The word "urticaria" itself comes from the Latin word "urtica" meaning "nettle," which relates to the similar appearance of nettle stings and the raised welts seen in this condition.
Individuals with urticaria factitia experience skin reactions shortly after physical contact or rubbing of their skin. The welts, or hives, may appear as red, swollen, and itchy bumps that often follow the pattern of the stimulus applied. The hives may disappear within minutes or hours, only to reappear with further contact.
The exact cause of urticaria factitia is unknown, but it is believed to involve a hypersensitivity reaction in the skin. The release of histamine, a chemical involved in the immune response, leads to the characteristic appearance and symptoms. This condition can be triggered by a wide array of stimuli such as scratching, pressure, friction, heat, cold, or vibration.
Urticaria factitia is typically diagnosed through a physical examination and a detailed medical history. Treatment options may include avoiding triggers, the use of antihistamines to alleviate symptoms, and in some cases, corticosteroids to reduce inflammation.
In conclusion, urticaria factitia is a specific type of urticaria characterized by the development of itchy, raised welts on the skin in response to physical stimuli. Proper diagnosis and management are crucial for individuals affected by this condition to minimize discomfort and improve

The term urticaria factitia is derived from Latin and Greek roots.
The word urticaria comes from Latin, derived from urtica which means nettle. Urticaria is a medical term for a skin condition characterized by the appearance of raised, itchy, and often reddish bumps on the skin, similar to the rash caused by stinging nettle plants.
The word factitia is derived from Latin as well, from facticius meaning artificial or made by art. It is used in medical terminology to describe a condition that is deliberately self-induced or artificially produced.
Therefore, urticaria factitia is a term used in medicine to refer to a condition where an individual intentionally causes or induces hives or rashes on their own skin, also known as dermographism or dermatographic urticaria.
