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 ...
Löfgren syndrome includes some of the same symptoms as traditional sarcoidosis, and presents with erythema nodosum (especially of the lower extremities), bilateral arthritis of the ankle joints, and hilar lymphadenopathy. (Note: Other symptoms are classically not present in Löfgren syndrome.)
The signs and symptoms depend on the organ involved. [2] Often, no symptoms or only mild symptoms are seen. [2] When it affects the lungs, wheezing, coughing, shortness of breath, or chest pain may occur. [3] Some may have Löfgren syndrome with fever, enlarged hilar lymph nodes, arthritis, and a rash known as erythema nodosum. [2]
Other symptoms due to sarcoidosis of other organs may be uveitis (inflammation of the uveal layer in the eye), dyspnoea (shortness of breath), arthralgia (joint pains), lupus pernio (a red skin rash, usually of the face), erythema nodosum (red skin lumps, usually on the shins), and symptoms of liver involvement or heart involvement (heart failure).
Dogs with the condition have a poor life expectancy and are often euthanised after diagnosis. [17] Clinical signs include: facial erythema , crusting and scaling, [ 18 ] skin lesions, lameness, ulcers, and disfiguration: it progresses to joint pain and azoospermia in males and disruption of the oestrous cycle in females.
Erythema nodosum is a form of panniculitis characterised by tender red nodules, 1–10 cm, associated with systemic symptoms including fever, malaise, and joint pain. Nodules may become bluish-purple, yellowing, and green, and subside over a period of 2–6 weeks without ulcerating or scarring.
Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, [1] [2] is a skin disease characterized by the sudden onset of fever, an elevated white blood cell count, and tender, red, well-demarcated papules and plaques that show dense infiltrates by neutrophil granulocytes on histologic examination.
Up to 80 percent of dogs infected will have symptoms, but the mortality rate is only 5 to 8 percent. [5] Infectious canine hepatitis is a sometimes fatal infectious disease of the liver. [6] Canine herpesvirus is an infectious disease that is a common cause of death in puppies less than three weeks old. [7]
