Cutaneous Lymphocytoma (Pseudolymphoma)

Cutaneous lymphocytoma (pseudolymphoma/Spiegler-Fendt sarcoid) is benign lymphoid hyperplasia presenting as red-brown papules/nodules on face/earlobes/genital, often after arthropod bite/Borrelia infection/drug/injection. Treatment: biopsy to exclude cutaneous lymphoma; investigate Borrelia (serology); oral amoxicillin/cefuroxime for borrelial lymphocytoma; topical/intralesional corticosteroids; excision/electrodessication; cryotherapy; reassurance; follow-up dermatology; monitor progression/atypia.

Common Symptoms

Reactive lymphoid hyperplasia (B/T-cell) to bite/borrelia/drug forms pseudolymphoma.

Treatment

Biopsy; anti-Borrelia antibiotics; topical/intralesional steroids; excision

Preventive Measures

Tick bite prevention; treat early borrelia.
