lymphadenopathy

 [lim-fad″ĕ-nop´ah-the]
disease of the lymph nodes; called also adenopathy.
angioimmunoblastic lymphadenopathy (angioimmunoblastic lymphadenopathy with dysproteinemia (AILD)) a systemic disorder resembling lymphoma characterized by fever, night sweats, weight loss, generalized lymphadenopathy, hepatosplenomegaly, macropapular rash, polyclonal hypergammaglobulinemia, and Coombs'-positive hemolytic anemia. It is considered to be a nonmalignant hyperimmune reaction to chronic antigenic stimulation; there is proliferation of B cells accompanied by profound deficiency of T cells. The disease follows a progressive but extremely variable course: some patients survive for a long period without chemotherapy; in other patients, overwhelming infections rapidly lead to death
dermatopathic lymphadenopathy regional lymph node enlargement associated with melanoderma and other dermatoses marked by chronic erythroderma.
immunoblastic lymphadenopathy angioimmunoblastic lymphadenopathy.
lymphadenopathy syndrome a condition occurring in immunocompromised individuals, characterized by unexplained lymphadenopathy for 3 or more months that involves extrainguinal sites, which on biopsy reveal nonspecific lymphoid hyperplasia. See also AIDS-related complex.

lymphadenopathy

Enlarged lymph nodes, follicular hypertrophy, swollen lymph glands Hematology Enlargement of lymph nodes of any etiology; the differential diagnostic considerations are multiple and divided into reactive patterns; benign lymphadenopathy is characterized by
1. Variability of the follicle–germinal center size;.
2. Lack of capsular or fat invasion;.
3. Mitotic activity confined to the germinal center;.
4. Cortical localization and inhomogeneous distribution of the follicles. See Angiography lymphadenopathy, Benign lymphadenopathy, Dermatopathic lymphadenopathy, Phenytoin lymphadenopathy, Shotty lymphadenopathy.

lymphadenopathy

(lim″fad″ĕ-nop′ă-thē) [ lymph- + adenopathy]
Enlarge picture
CERVICAL LYMPHADENOPATHY: Squamous cell carcinoma of the neck
Enlargement of lymph nodes (LN), typically to greater than 1.5 cm. The increased size is caused by activation and proliferation of lymphocytes and phagocytic white blood cells within the node or by invasion of the node by tumor. Most often, lymphadenopathy is found in nodes involved in local, regional, or systemic infections; it results occasionally from cancers. Lymphadenopathy may also be found in an array of other, less common illnesses, including thyroiditis, thyrotoxicosis, autoimmune diseases (e.g., rheumatoid arthritis), sarcoidosis, and drug reactions (e.g., phenytoin). See: illustration

Enlarged LNs may be tender or not; tenderness often is present when lymph nodes swell rapidly (e.g., in response to infections, hypersensitivity reactions, or some fulminant lymphomas). Rock-hard, enlarged, and immobile LNs are typical of metastatic cancer, whereas rubbery LNs are found in lymphomas. LNs that do not resolve spontaneously within 4 to 6 weeks, or for which no obvious explanation exists, usually are sampled by biopsy or aspiration.

dermatopathic lymphadenopathy

Widespread lymphadenopathy secondary to various skin disorders.

Patient discussion about lymphadenopathy

Q. my friend ate a bar of chocolate and now her left neck gland is swollen any ideas why? no other symptoms

A. it can be an infection -just like brandon said- or although this is rare, it can also be an allergic reaction.
if it is an infection, you can usually find such other infection symptoms like : fever, pain in that swollen area, increased white blood cells (in blood work test), etc.

if it is an allergy, usually it will fade away itself in couple of days, or you can just try to consume anti-allergic drugs, such as : loratadine and maybe combined with dexamethasone.

Good luck, and stay healthy always..

In this retrospective and cross-sectional study, files of a total of 1700 patients younger than 18 years of age with cervical, axillary, inguinal, mesenteric, and supraclavicular lymphadenopathies who were referred to Clinics of Paediatric Diseases, and Paediatric Surgery of Gaziantep Children's Hospital between January 2012, and January 2015 were retrospectively evaluated.

After these considerations, we were drawn to the associated clinical background of this patient, that is, a long-standing asthma and a possibility that these lymphadenopathies were all secondary to a forme fruste CSS.
In this area of north-eastern region (Manipur), where advanced and costly diagnostic facilities were not easily available to all groups of patients, FNAC formed an easy, inexpensive, reliable and readily acceptable diagnostic tool for superficial lymphadenopathies. In our study we presented the cytomorphologic diagnosis of 378 cases of lymphadenopathies over a period of 4 years, i.e.
Another limitation of our study was that we did not test for fungi or viruses that may also represent causes of lymphadenopathies. Mycobacterial infections in our study were diagnosed by culture and confirmed retrospectively by using a real-time quantitative PCR.
Although most infectious lymphadenopathies show nonspecific histologic findings, diagnostic morphologic features can be seen in a few reactive conditions, such as infectious mononucleosis, cat scratch disease, lymphogranuloma venereum, syphilis, virus-associated hemophagocytic syndrome, and HIV infection.[1,2] The cases presented in this report illustrate an unusual cause of lymphadenopathy secondary to Actinomyces infection.
Routine use of FNAC can help us to diagnose the types of lymphadenopathies.
On examination there were multiple lymphadenopathies in above mentioned areas with size ranging from 3x2 to 4x3 cm in size, with smooth surface, well defined margin, soft in consistency with normal overlaying skin.
