Erythema contusiforme, when a subcutaneous hemorrhage (bleeding under the skin) occurs with an erythema nodosum lesion, causing the lesion to look like a contusion (bruise) Erythema nodosum migrans (also known as subacute nodular migratory panniculitis ), a rare form of chronic erythema nodosum characterized by asymmetrical nodules that are ...
Ulcerative colitis may affect the skin. The most common type of skin manifestation, erythema nodosum, presents in up to 3% of UC patients. It develops as raised, tender red nodules usually appearing on the outer areas of the arms or legs, especially in the anterior tibial area (shins). [34]
Erythema nodosum is the most common type of skin problem, occurring in around 8% of people with Crohn's disease, producing raised, tender red nodules usually appearing on the shins. [55] [68] [69] Erythema nodosum is due to inflammation of the underlying subcutaneous tissue, and is characterized by septal panniculitis. [68]
Yersiniosis is an infectious disease of the gastrointestinal tract caused by bacteria of the genus Yersinia other than Y. pestis. Most cases of yersiniosis in humans are caused by Y. enterocolitica, with a small minority being caused by Y. pseudotuberculosis. Rarely, other species of the genus can cause yersiniosis. [1]
Perianal cellulitis, also known as perianitis or perianal streptococcal dermatitis, is a bacterial infection affecting the lower layers of the skin around the anus. [1] [2] [3] It presents as bright redness in the skin and can be accompanied by pain, difficulty defecating, itching, and bleeding.
Y. enterocolitica infections are sometimes followed by chronic inflammatory diseases such as arthritis, [12] erythema nodosum, and reactive arthritis. This is most likely because of some immune-mediated mechanism. [13] Y. enterocolitica seems to be associated with autoimmune Graves-Basedow thyroiditis. [14]
In severely ill people with IBD there is a risk of the passage of viable bacteria from the gastrointestinal tract to the internal organs (bacterial translocation) and subsequent bacteremia, which can cause serious adverse health consequences. [135]
Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. [2]
