“…[35][36][37]39,40 There was also a unique case with evidence of extremely dilated dermal vessel, RBC extravasate, and nuclear dust in pathology. 39 Erythematous/Maculopapular/Morbilliform Rash Histopathologic studies on post-COVID vaccination revealed erythematous, maculopapular, and morbilliform rashes with perivascular and perifollicular lymphohistiocytic infiltrates, 35,[41][42][43][44][45][46][47] neutrophils, and abundant eosinophils in the epidermis, 35,43 spongiosis, basal cell vacuolization, 42,43,46 and apoptotic cells, 43,47 with morbilliform erythema. Histopathology of erythematous maculopapular plaques or patches were reported as follows: inflammatory infiltrates within dermis primarily including lymphocytes, eosinophils, and occasional histiocytes, 38,42,43,[48][49][50][51][52][53] spongiosis, RBCs extravasation, 38,42,44,48,52,53 widened rete ridges, 54 orthokeratosis, parakeratosis, 38,45,54 and vacuolization of basal layer cells.…”
