Immunofluorescence reveals the presence of immunoreactants, particularly IgM and C3, along the basement membrane zone and in vessels of the papillary dermis in a small number of cases.1616 Immunoperoxidase studies have shown that the lymphocytes in the dermal infiltrate are T cells, particularly of the cytotoxic/suppressor (CD8) type in PLEVA, although CD4+ cells appear to predominate in the chronic form.1569 Another study found a predominance of CD8+ cells in both forms of the disease.1600 Approximately 5% of the perivascular cells are Langerhans or indeterminate cells.1598 CD1a+ cells are also increased in the epidermis. Pityriasis lichenoides (PL) is a spectrum of inflammatory skin diseases which include PL et varioliformis acuta (PLEVA) and PL chronica (PLC) as two ends of the disease and rarely both entities can coexist on the same patient.

Pityriasis lichenoides chronica (PLC), which is characterized by the appearance of multiple scaly, red-brown papules on the skin, is often considered to be on a disease continuum with PLEVA ( picture 2) [ 1 ].

To better link the association between vaccination and PLC, we used the Adverse Drug Reaction Probability Scale (Naranjo Scale) and found that our case scored 7, which indicates a probable causality relationship between the Pfizer-BioNTech vaccine and PLC.14 However, it is important to highlight that the Naranjo Scale is a 10-questionbased score system, and one of these questions mandates the presence of 2 or more published case reports with the same adverse events to count the score of that question.14 Therefore, this case could aid in the identification of the COVID-19related PLC vaccine when the Naranjo scale is used, as it is the second case to be published in this regard.
