We would like to present a special case in the context of the COVID-19 pandemic. A 41-year-old man was admitted to our Department of Dermatology at the University of Münster, Germany with changes to a 20-year-old black-coloured tattoo located on his right deltoid muscle. The changes had developed over a period of 5 months. He had noted these changes approximately 10 days after the second vaccination with the mRNA Comirnaty© vaccine (BNT162b2 Pfizer-BioNTech COVID-19 vaccine; Pfizer (New York, USA) - BioNTech (Mainz, Germany)). The second dose of the vaccine was administered to his left arm, the opposite side to his tattoo. Mild swelling of the injection area and fatigue were also reported by the patient. However, these symptoms disappeared within 2–3 days. He did not recall any previous changes to his tattoo. His history further disclosed allergic asthma and allergic rhinoconjunctivitis. The patient reported that topical corticosteroids and tacrolimus had no effect on the skin lesions.
Dermatological examination revealed a sharply defined swelling of the entire black-coloured tattoo (Fig. 1). No other skin changes were detected. A skin biopsy from the swollen tattooed skin showed sarcoidal granulomatous dermatitis with exogenous pigment deposits consistent with granulomatous tattoo reaction or cutaneous manifestation of sarcoidosis (Fig. 2). Additional laboratory tests revealed elevated angiotensin converting enzyme (ACE 56 U/L; normal range 8–52 U/L) and soluble interleukin-2 receptor (sIL-2R 1,069 U/mL; normal range 158–623 U/mL). All other laboratory parameters were within normal ranges. A computed tomography scan of the chest further disclosed mediastinal lymphadenopathy, in accordance with the diagnosis of systemic sarcoidosis, stage I. Intralesional triamcinolone injections and/or peroral hydroxychloroquine was/were recommended. Under medication with hydroxychloroquine, 200 mg twice a day, the swelling decreased, but the patient lost his appetite and lost weight; hence he reduced the dose and then stopped taking the medication.

Tattoo-induced skin and systemic sarcoidosis have been reported previously (1). Thus, vaccinations against influenza or with Bacillus Calmette-Guérin have been described as triggers for sarcoidosis (2, 3). With regard to COVID-19 disease, both COVID-19 infections and vaccinations against COVID-19 have been associated with onset of a variety of inflammatory and autoimmune-mediated diseases, including systemic sarcoidosis (4). In 2021, an acute, ulcerative, sarcoidal tattoo reaction following COVID-19 vaccination was reported and described as a “Sweet-like phenomenon”. However, in the latter case, laboratory markers, such as ACE and lung imaging, were inconspicuous, excluding the diagnosis of sarcoidosis (5). In contrast to this case, the patient in the current report showed clear signs of sarcoidosis, such as mediastinal lymphadenopathy and elevated levels of ACE. To the best of our knowledge, systemic sarcoidosis with a granulomatous tattoo reaction following COVID-19 vaccination has not been described previously. Possible pathophysiological mechanisms include pro-inflammatory mechanisms, such as the release of interferon gamma produced by T-cells after COVID-19 vaccination (6). Interferon gamma also activates macrophages, which are key players in tattoo reactions (7) and in sarcoidosis (8). Cytokine storms associated with COVID-19 (9) and COVID-19 vaccination (10) may favour the development of granulomas at cutaneous sites of high antigenic content, such as tattoos. The current case highlights that changes in tattoos can be the first clinical sign of sarcoidosis and also reports that this complication developed following COVID-19 vaccination.
