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..
