Cauliflower ear is an irreversible condition that occurs when the external portion of the ear is hit and develops a blood clot or other collection of fluid under the perichondrium. This separates the cartilage from the overlying perichondrium that supplies its nutrients, causing it to die and resulting in the formation of fibrous tissue in the overlying skin. As a result, the outer ear becomes permanently swollen and deformed, resembling a cauliflower. The condition is common in martial arts such as Brazilian jiu-jitsu, wrestling, boxing, kickboxing, judo or mixed martial arts and in full-contact sports such as rugby union. Presentation
People presenting with possible auricular hematoma often have additional injuries (for example, head/neck lacerations) due to the frequently traumatic causes of auricular hematoma. The ear itself is often tense, fluctuant, and tender with throbbing pain. However, because of potentially more remarkable injuries often associated with auricular hematoma, auricular hematoma can easily be overlooked without directed attention. Causes
The most common cause of cauliflower ear is blunt trauma to the ear leading to a hematoma which, if left untreated, eventually heals to give the distinct appearance of cauliflower ear. The structure of the ear is supported by a cartilaginous scaffold consisting of the following distinct components: the helix, antihelix, concha, tragus, and antitragus.
Also, a lack of symptoms is not a reliable indicator of intestinal recuperation.If alternative causes of villous atrophy have been eliminated, steroids or immunosuppressants (such as azathioprine) may be considered in this scenario.Refractory coeliac disease should not be confused with the persistence of symptoms despite gluten withdrawal caused by transient conditions derived from the intestinal damage, which generally revert or improve several months after starting a gluten-free diet, such as small intestinal bacterial overgrowth, lactose intolerance, fructose, sucrose, and sorbitol malabsorption, exocrine pancreatic insufficiency, and microscopic colitis among others. Epidemiology
Globally coeliac disease affects between 1 in 100 and 1 in 170 people. Rates, however, vary between different regions of the world from as few as 1 in 300 to as many as 1 in 40. In the United States it is thought to affect between 1 in 1750 (defined as clinical disease including dermatitis herpetiformis with limited digestive tract symptoms) to 1 in 105 (defined by presence of IgA TG in blood donors). Due to variable signs and symptoms it is believed that about 85% of people affected are undiagnosed. The percentage of people with clinically diagnosed disease (symptoms prompting diagnostic testing) is 0.05–0.27% in various studies. However, population studies from parts of Europe, India, South America, Australasia and the USA (using serology and biopsy) indicate that the percentage of people with the disease may be between 0.33 and 1.06% in children (but 5.66% in one study of children of the predisposed Sahrawi people) and 0.18–1.2% in adults.
