Article Synopsis
- Skin local reactions to mRNA COVID-19 vaccines may be linked to vaccine excipients, prompting a study on skin testing for delayed reactions.
- The study involved healthcare workers with adverse skin reactions to the vaccines, testing them with various excipients and comparing results to a control group without reactions.
- Results showed a high percentage of delayed skin reactions to PEG-2000 in those with delayed large local reactions, suggesting PEG's potential role in these skin reactions, while testing for other excipients was not significant.
A 59-year-old woman presented with a persistent eruption manifested as multiple agminated miliary facial papules. Histopathological examination showed prominent nodular dermal lymphoid infiltrates with hyperplastic follicles that were initially interpreted as B-cell reactive lymphoid hyperplasia. Several years later, an additional biopsy showed a dense perifollicular infiltrate with reactive primary and secondary follicles.

Treatment with oral ursodeoxycholic acid was prescribed, and a complete and persistent resolution of skin lesions was noted. This observation seems to support that acquired palmoplantar keratoderma is an uncommon cutaneous manifestation of primary biliary cholangitis.
