Clinical narrative: right foot between 2nd and 3rd toe one huge blister appeared/blisters are spreading slowly all over the body, to his chest, arms, hips; a few days later some red bumps appeared in his ankle; urticarial phase of bullous pemphigoid/bullous pemphigoid also called blistering disease/The biopsy result is a superficial and mid dermal perivascular dermatitis with frequent eosinophils; This spontaneous case was reported by an other health care professional and describes the occurrence of PEMPHIGOID (urticarial phase of bullous pemphigoid/bullous pemphigoid also called blistering disease/The biopsy result is a superficial and mid dermal perivascular dermatitis with frequent eosinophils) and BLISTER (right foot between 2nd and 3rd toe one huge blister appeared/blisters are spreading slowly all over the body, to his chest, arms, hips) in a 77-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch no. 060A22A) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.     Family history included Melanoma.    On 22-Jun-2022, the patient received fourth dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 30-Jun-2022,  after starting mRNA-1273 (Moderna COVID-19 Vaccine), the patient experienced PEMPHIGOID (urticarial phase of bullous pemphigoid/bullous pemphigoid also called blistering disease/The biopsy result is a superficial and mid dermal perivascular dermatitis with frequent eosinophils) (seriousness criterion medically significant). On an unknown date, the patient experienced BLISTER (right foot between 2nd and 3rd toe one huge blister appeared/blisters are spreading slowly all over the body, to his chest, arms, hips) (seriousness criterion medically significant) and MACULE (a few days later some red bumps appeared in his ankle). The patient was treated with DEXAMETHASONE (DECADRON [DEXAMETHASONE]) for Bullous pemphigoid, at an unspecified dose and frequency; DIPHENHYDRAMINE HYDROCHLORIDE (BENADRYL [DIPHENHYDRAMINE HYDROCHLORIDE]) for Bullous pemphigoid, at an unspecified dose and frequency; TRIAMCINOLONE ACETONIDE for Bullous pemphigoid, at an unspecified dose and frequency and CLOBETASOL for Bullous pemphigoid, at an unspecified dose and frequency. At the time of the report, PEMPHIGOID (urticarial phase of bullous pemphigoid/bullous pemphigoid also called blistering disease/The biopsy result is a superficial and mid dermal perivascular dermatitis with frequent eosinophils) had not resolved and BLISTER (right foot between 2nd and 3rd toe one huge blister appeared/blisters are spreading slowly all over the body, to his chest, arms, hips) and MACULE (a few days later some red bumps appeared in his ankle) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 11-Jul-2022, Biopsy: Result is a superficial and mid dermal perivascular dermatitis with frequent eosinophils..     For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   No concomitant medications were reported. No past medical history was reported, and no medical history related to AE and both Acute and Chronic illnesses at the time of vaccination. Patient was not tested positive for COVID-19 since. No other vaccines given within 1 month prior to Moderna COVID-19 vaccine. No similar events were experienced by the patient in the past.

The patient was sent to a laboratory by the Physician and the lab performed a biopsy of the lesions. The biopsy result is a superficial and mid dermal perivascular dermatitis with frequent eosinophils. The differential diagnosis for the lesion on the patients left leg includes arthropod bite, hypersensitivity dermatitis, drug eruption, and urticarial phase of bullous pemphigoid. PAS-LG Stain for Fungi is pending. On the patients left great big toe the patient reports lichen simplex chronicus with evidence of prior erosion/ulceration. A few of the blisters have resolved after the patients physician treated with Dexamethasone.  After 2nd booster, on 26-Jun-2022 patient started to develop a rash in his left foot with blisters, and on 30-Jun-2022, patient visited a nurse practitioner who diagnosed with bullous pemphigoid also called blistering disease, which is a very rare and bad disease with no cure that can be deadly.
