Childhood cutaneous lymphoid hyperplasia following feline scratches.

Cutaneous lymphoid hyperplasia or pseudolymphoma is a usually benign inflammatory response that mimics lymphoma. Stimulation from foreign antigens introduced into the skin can induce this response. Scratches from pets are an effective mode of transmitting infections and inoculating foreign antigens into the skin. We report an unusual case of a child where cutaneous lymphoid hyperplasia presented as subcutaneous nodules at sites scratched by a pet cat.
