The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels. Typical signs and symptoms include nosebleeds, stuffy nose and crustiness of nasal secretions, and inflammation of the uveal layer of the eye. [3] Damage to the heart, lungs and kidneys can be fatal. The cause of GPA is unknown.
Eosinophilic granulomatosis with polyangiitis consists of three stages, but not all patients develop all three stages or progress from one stage to the next in the same order; [7] whereas some patients may develop severe or life-threatening complications such as gastrointestinal involvement and heart disease, some patients are only mildly affected, e.g. with skin lesions and nasal polyps. [8]
The lesion is in some cases very difficult to distinguish from breast cancer and other causes such as infections (tuberculosis, syphilis, corynebacterial infection, mycotic infection), autoimmune diseases (sarcoidosis, granulomatosis with polyangiitis), foreign body reaction and granulomatous. Reaction in a carcinoma must be excluded.
Lymphomatoid granulomatosis (LYG or LG) is a very rare lymphoproliferative disorder first characterized in 1972. [1] Lymphomatoid means lymphoma -like and granulomatosis denotes the microscopic characteristic of the presence of granulomas with polymorphic lymphoid infiltrates and focal necrosis within it.
The disease's symptoms can range from catastrophic neurological impairment to an asymptomatic condition brought on by impalpable pulses or bruits. [7] Non-specific features include mild anemia, myalgia, arthralgia, weight loss, malaise, night sweats, and fever. [8] Giant cell arteritis (GCA) is the most common type of systemic vasculitis in adults.
Palisaded neutrophilic and granulomatous dermaititis is associated with subacute bacterial endocarditis, [4] ledipasvir/sofosbuvir, [5] allopurinol, [6] Hodgkin’s and non-Hodgkin’s lymphoma, [4] chronic myelomonocytic leukemia, [7] ulcerative colitis, [8] Takayasu arteritis, [4] systemic vasculitis, [8] systemic lupus erythematosus (SLE), [9] sarcoidosis, [10] rheumatoid arthritis, [11 ...
p-ANCA is associated with several medical conditions: [3] It is fairly specific, but not sensitive for ulcerative colitis, so is not useful as a sole diagnostic test. [4] When measured together with anti-saccharomyces cerevisiae antibodies (ASCA), p-ANCA has been estimated to have a specificity of 97% and a sensitivity of 48% in differentiating patients with ulcerative colitis from normal ...
The additional cells are sometimes a clue to the cause of the granuloma. For example, granulomas with numerous eosinophils may be a clue to coccidioidomycosis or allergic bronchopulmonary fungal disease, and granulomas with numerous neutrophils suggest blastomycosis, granulomatosis with polyangiitis, aspiration pneumonia, or cat-scratch disease.
