DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available):In June 2021, Biopsy: abnormal (abnormal) In Jul-2021 results revealed pseudolymphoma.No concomitant medications were reported.On 01-May-2021, three and half weeks after receiving second dose, the patient had pimple or bump on the forehead which was later diagnosed as pseudolymphoma on an unknown date in Jul-2021.On an unknown date in Aug-2021, the patient started treatment with steroid cream  and the bump went away but left a dent on the forehead.

The event of Pseudolymphoma occurred approximately 3.5 weeks after the second dose of mRNA- 1273 vaccine and the event skin mass and pruritus happened approximately after 9 weeks after the second dose of the mRNA 1273 vaccine . Clinical manifestations included a pruriginous mass in the forehead. Skin biopsy showed pseudolymphoma. She was prescribed a topical steroid cream,  with resolution of the skin bump. The event Skin mass  with clinical manifestations included a "kidney sized" skin mass on her stomach associated with pruritus. Skin biopsy is pending. The rechallenge is not applicable, since the events were reported exclusively after the second dose. The benefit-risk relationship of mRNA- 1273 vaccine is not affected by this report.; Sender's Comments: This spontaneous case concerns a 59-year-old female patient with no relevant medical history, who experienced the unexpected non serious events of Pseudo lymphoma, Skin mass and pruritus.
