- Distribution
- Uncommon
- Lymphoma (Hodgkin, non-hodgkin)
- Metastatic cancer
- Salivary Gland Tumor (e.g. Parotid Tumor)
- Sarcoidosis
- Painless Lymphadenopathy (cervical, axillary, inguinal)
- Sjogren Syndrome
- Bilateral Parotid Gland enlargement
- Amyloidosis
- Painless Generalized Lymphadenopathy
- May be associated with other systemic disease (e.g. CHF, Nephrotic Syndrome, Neuropathy)
- Rare
- Castleman Disease (angiofollicular lymphoproliferative disease)
- Benign lymphoproliferative condition of mediastinum presenting with a single inflamed Lymph Node
- Kikuchi Disease (histiocytic necrotizing Lymphadenitis)
- Self limited (3 month course) of fever, posterior Lymphadenopathy and Leukopenia
- Kimura Disease
- Non-tender, idiopathic Subcutaneous Mass associated with Eosinophilia; endemic in Asia
- Rosai-Dorfman Disease
- Matted Lymphadenopathy with occasional fever in otherwise healthy adults
- Castleman Disease (angiofollicular lymphoproliferative disease)
IV. Causes: Chronic (months to years)
- Common
- Uncommon (in adults)
- Lipoma
- Laryngocele
- Due to recurrent forceful nose blowing, coughing or wind instrument use
- Mass lateral to the Thyroid cartilage
- Increases in size with increased laryngeal pressure
- Congenital Anomaly
- Branchial Cleft Cyst
- Upper Neck Mass, anterior to sternocleidomastoid Muscle
- May enlarge with Upper Respiratory Infections, or present with acute inflammation
- Typically diagnosed in childhood
- Thyroglossal Duct Cyst
- Midline Neck Mass near Hyoid Bone that elevates with Swallowing or Tongue protrusion
- Dermoid Cyst
- Congenital, benign, slow-growing soft, doughy cyst in midline submental neck (children, young adults)
- Branchial Cleft Cyst
- Parasympathetic tumors or paragangliomas of the neck (Flushing, Palpitations, Hypertension with local affects)
- Carotid body tumor
- Glomus jugulare tumor
- Glomus vagale tumor
- Rare
- Parathyroid cancer or Parathyroid cyst
- Liposarcoma
V. Causes: Malignant Adult Neck Masses
- Metastatic Squamous Cell Carcinoma
- Thyroid Cancer

-
Congenital Anomaly
- Lateral neck
- Brachial cleft cyst
- Cystic Hygroma
- Dermoid
- Medial Neck
- Lateral neck
- Miscellaneous Conditions
- Sarcoidosis

- Castleman Disease (angiofollicular lymphoproliferative disease)
- Benign lymphoproliferative condition of mediastinum presenting with a single inflamed Lymph Node
- Kikuchi Disease (histiocytic necrotizing Lymphadenitis)
- Self limited (3 month course) of fever, posterior Lymphadenopathy and Leukopenia
