Approach to Lymphadenopathy

Lymphadenopathy is defined as enlargement of lymph nodes. This process is often secondary to infection and is frequently benign and self-limited. Viral or bacterial infections lead to localized responses from lymphocytes and macrophages, leading to enlargement of nodes. There may also be localized infiltration by inflammatory cells in response to an infection of the nodes themselves. This is known as a lymphadenitis. Finally, it is crucial to rule out rarer, more serious causes such as lymphomas or leukemias, which are due to proliferation of neoplastic lymphocytes or macrophages.

For better or worse tattoos are meant to stay with you forever. New research, though, suggests that their permanence is more than skin deep.

Why Wouldn’t the Lump Under the Patient’s Jaw Go Away?

The 40-year-old man stared into the mirror. Lowering his razor, he lifted his chin to see if the lima-bean-size lump was still visible on the right side of his neck, just under his jawbone.
