By extent:
Localized lymphadenopathy: due to localized spot of infection e.g., an infected spot on the scalp will cause lymph nodes in the neck on that same side to swell up
Generalized lymphadenopathy: due to a systemic infection of the body e.g., influenza or secondary syphilis
Persistent generalized lymphadenopathy (PGL): persisting for a long time, possibly without an apparent cause
By localization:
Hilar lymphadenopathy. Mediastinal lymphadenopathy
Bilateral hilar lymphadenopathy
Dermatopathic lymphadenopathy: lymphadenopathy associated with skin disease. By malignancy: Benign lymphadenopathy is distinguished from malignant types which mainly refer to lymphomas or lymph node metastasis. Size
By size, where lymphadenopathy in adults is often defined as a short axis of one or more lymph nodes is greater than 10mm. However, there is regional variation as detailed in this table:Lymphadenopathy of the axillary lymph nodes can be defined as solid nodes measuring more than 15 mm without fatty hilum. Axillary lymph nodes may be normal up to 30 mm if consisting largely of fat.In children, a short axis of 8 mm can be used. However, inguinal lymph nodes of up to 15 mm and cervical lymph nodes of up to 20 mm are generally normal in children up to age 8–12.Lymphadenopathy of more than 1.5–2 cm increases the risk of cancer or granulomatous disease as the cause rather than only inflammation or infection. Still, an increasing size and persistence over time are more indicative of cancer. See also

For this reason, patients who develop and report these symptoms, and subsequently byssinosis, are one of the reasons why the term Monday Fever exists. Byssinosis can become chronic in a patient if they are continually exposed to cotton, jute, or yarn dust over time. Byssinosis can be misdiagnosed as COPD, or asthma however the difference in these lung diseases and byssinosis comes from the etiology. Byssinosis can ultimately result in narrowing of the airways, lung scarring and death from infection or respiratory failure. Extended exposure to cotton or jute dust can lead to impaired lung function and further respiratory complications. Patients may require oxygen to assist with breathing and may also have difficulty exercising. Diagnosis
It can be difficult to accurately diagnose a patient with byssinosis due to symptoms that are similar to other respiratory diseases such as chronic obstructive pulmonary diseases (COPD), asthma, or bronchitis. Byssinosis can be misdiagnosed as other pneumoconioses therefore a chest x-ray and/or lung function test is needed to accurately diagnose a patient who may have byssinosis. The main distinction of byssinosis from other respiratory diseases comes from the initial exposure. Patients who have byssinosis have typically been exposed to cotton or just dust for an extended period of time and experience symptoms of chest tightness and coughing.Patient history should reveal exposure to cotton, flax, hemp, or jute dust. Measurable change in lung function before and after working shifts is key to diagnosis. Patients with byssinosis show a significant drop in FEV1 over the course of work shift.
