• #2 Aphthous stomatitis – Wikipedia

  https://en.wikipedia.org/wiki/Aphthous_stomatitis

  Diagnosis is mostly based on the clinical appearance and the medical history. The most important diagnostic feature is a history of recurrent, self healing ulcers at fairly regular intervals. Although there are many causes of oral ulceration, recurrent oral ulceration has relatively few causes, most commonly aphthous stomatitis, but rarely Behet’s disease, erythema multiforme, ulceration associated with gastrointestinal disease, and recurrent intra-oral herpes simplex infection. A systemic cause is more likely in adults who suddenly develop recurrent oral ulceration with no prior history. […] Special investigations may be indicated to rule out other causes of oral ulceration. These include blood tests to exclude anemia, deficiencies of iron, folate or vitamin B12, or celiac disease. However, the nutritional deficiencies may be latent and the peripheral blood picture may appear relatively normal. Some suggest that screening for celiac disease should form part of the routine work up for individuals complaining of recurrent oral ulceration. Many of the systemic diseases cause other symptoms apart from oral ulceration, which is in contrast to aphthous stomatitis where there is isolated oral ulceration. Patch testing may be indicated if allergies are suspected (e.g. a strong relationship between certain foods and episodes of ulceration). Several drugs can cause oral ulceration (e.g. nicorandil), and a trial substitution to an alternative drug may highlight a causal relationship.

  The diagnosis of aphthous ulcers (canker sores) is usually based on the history and clinical presentation. No laboratory procedures are available for definitive diagnosis. Note the following: […] In patients with severe recurrent aphthous ulcers (RAUs), or canker sores, the clinical picture should guide laboratory testing. A complete blood cell (CBC) count, a chemistry panel, and nutritional workup may be necessary. […] Patients with suspected malabsorption or a nutritional deficiency should undergo immediate screening. Consider screening in patients presenting with a history of recurrent aphthous ulcers (canker sores) lasting 6 months or longer. […] CBC counts may be within the reference range in patients with recurrent aphthous ulcers (canker sores), although some have found anemia in 21%. Findings of neutropenia suggest Sweet syndrome or cyclic neutropenia; findings of leukocytosis suggest periodic fever, aphthous pharyngitis, and adenopathy (PFAPA) syndrome.

While not routinely needed for most cases, however, laboratory tests may be used to rule out underlying systemic conditions, particularly in severe or atypical cases. […] Although no specific tests for RAS are available, the following tests may be helpful in excluding systemic disorders: Complete blood count (CBC), Hemoglobin test, White blood cell (WBC) count with differential, Red blood cell indices, Iron studies (usually an assay of serum ferritin levels), Red blood cell folate assay, Serum vitamin B-12 measurements, Serum antiendomysium antibody and transglutaminase assay (positive in celiac disease).

  Tissue biopsy is not usually required, unless to rule out other suspected conditions such as oral squamous cell carcinoma. The histopathologic appearance is not pathognomonic (the microscopic appearance is not specific to the condition). Early lesions have a central zone of ulceration covered by a fibrinous membrane. In the connective tissue deep to the ulcer there is increased vascularity and a mixed inflammatory infiltrate composed of lymphocytes, histiocytes and polymorphonuclear leukocytes. The epithelium on the margins of the ulcer shows spongiosis and there are many mononuclear cells in the basal third. There are also lymphocytes and histiocytes in the connective tissue surrounding deeper blood vessels near to the ulcer, described histologically as „perivascular cuffing”.
