Article:

This manuscript presents a report of bullous pemphigoid rash associated with COVID-19 for the first time. The objective of this manuscript is to present a unique dermatological case in the setting of a COVID-19-positive infection to further recognize the virus symptomatology. A 37-year-old female with a past medical history of class III obesity, type II diabetes mellitus, and hypertension presented to the emergency department in September 2020 with inpatient and outpatient follow-up through to November 2020. The patient denied any personal or family history of skin disorders. The patient tested positive for COVID-19 prior to hospitalization and presented to the hospital with severe, persistent, pruritic rash meeting dermatopathological, serologic, and clinical criteria for bullous pemphigoid diagnosis. Histopathology H&E punch biopsy from her left flexor wrist demonstrated epidermal keratinocyte necrosis, subepidermal vesiculation with eosinophils, gossamer stranding of the papillary dermis, and subepidermal edema. Direct immunofluorescence punch biopsy from her left flexor wrist demonstrated strong linear IgG staining at the dermoepidermal junction, with weaker and focal linear C3 staining. Antigen-specific serology was consistent with bullous pemphigoid. There was no previously reported cutaneous association of COVID-19 infection with bullous pemphigoid making this case an important addition to the body of evidence helping to identify bullous pemphigoid in the setting of viral infection.
