What is borrelial lymphocytoma in Lyme disease?

[Connor]

@khalidah Less than 1% of patients with stage 2 Lyme disease, almost all of them European, develop Borrelia lymphocytoma, described as a small, bluish-red nodule or plaque. The earlobe and scrotum are the typical location in children whereas the nipple is the more common location in adults.
Borrelial lymphocytoma tends to occur in areas of previous (or concurrent) erythema migrans and may be up to a few centimeters in size. Regional lymphadenopathy may be present.

Other terms used to describe borrelial lymphocytoma include the following:

Lymphadenosis benigna cutis
Lymphocytoma cutis
Cutaneous lymphoid hyperplasia
Spiegler-Fendt lymphoid hyperplasia
