Borrelial pseudolymphoma of the nose

[Guide]

A 52-year-old Colombian woman, a patient with psoriasis, undergoing phototherapy with (ultraviolet B narrowband) UVBnb, presented with a symptomless solitary diffuse erythaematous plaque on her nose for 3 months. Initially, she was treated with pimecrolimus 1% cream for 8 weeks, which was then combined with metronidazole cream for 4 weeks, with the initial diagnosis of UV-triggered rosacea, without improvement. A punch biopsy was performed and the histology showed a pseudolymphomatous reaction. The diagnosis of nasal pseudolymphoma of borreliosis was confirmed with PCR. The lesion completely resolved following oral doxycycline therapy.
