Post-implantation erythema in 3 patients and a review of reticular telangiectatic erythema

Objective. To demonstrate the variety in clinical presentation of patients presenting with RTE or similar patch test-negative post-implantation erythema. Patients/Materials/Methods. After institutional board approval had been obtained, patient information was obtained from electronic medical record files, which included surgical reports, pathology reports, and notes from outpatient encounters. Results. We report post-implantation erythema following insertion of an elbow prosthesis, a knee prosthesis, and a spinal cord stimulator, which have not previously been cited as aetiologies of RTE. Conclusion. Owing to the delayed onset and variable recovery, RTE remains a diagnostic challenge. RTE should be included in the differential diagnosis of any patient presenting with erythema over the site of a previously implanted device.
