An unusual cause of cervical adenopathy. Extramedullary hematopoiesis.
A painless lateral neck mass in an otherwise healthy 58-year-old man is a frequent diagnostic problem. We have recently seen such a patient with a cervical neck mass whose preoperative evaluation findings were normal. Excisional biopsy revealed a lymph node exhibiting changes compatible with extramedullary hematopoiesis. This becomes an additional unusual cause of enlarged lateral neck nodes.
