looks like if you are on a blood thinner where you have those kind of skin necrosis only he is not on a blood thinner.; itching did not start until the 2nd dose for the itching and now this skin pattern where it is easy to bleed started much later and he has patching that was there he thought from the itching; itching has increased dramatically; noticed as of late there is a larger pattern of bruising/patching that is bruised; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A 62-year-old male patient received BNT162b2 (BNT162B2), on 16Jun2022 as dose 3 (booster), single (Lot number: FJ4991) at the age of 61 years for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: BNT162b2 (dose 1, lot number: EP6955), administration date: 19Mar2021, when the patient was 60-year-old, for COVID-19 Immunization, reaction(s): "rash on left arm above his wrist on forearm", "itching all over the body after rash formed"; BNT162b2 (Dose 2), administration date: 09Apr2021, when the patient was 60-year-old, for COVID-19 Immunization, reaction(s): "itching did not start until the 2nd dose for the itching and now this skin pattern where it is easy to bleed started much later and he has patching that was there he thought from the itching", "itching has increased dramatically", "looks like if you are on a blood thinner where you have those kind of skin necrosis only he is not on a blood thinner", "noticed as of late there is a larger pattern of bruising/patching that is bruised". The following information was reported: SKIN NECROSIS (medically significant), outcome "unknown", described as "looks like if you are on a blood thinner where you have those kind of skin necrosis only he is not on a blood thinner."; SKIN HAEMORRHAGE (non-serious), outcome "unknown", described as "itching did not start until the 2nd dose for the itching and now this skin pattern where it is easy to bleed started much later and he has patching that was there he thought from the itching"; PRURITUS (non-serious), outcome "not recovered", described as "itching has increased dramatically"; CONTUSION (non-serious), outcome "unknown", described as "noticed as of late there is a larger pattern of bruising/patching that is bruised". The events "looks like if you are on a blood thinner where you have those kind of skin necrosis only he is not on a blood thinner.", "itching did not start until the 2nd dose for the itching and now this skin pattern where it is easy to bleed started much later and he has patching that was there he thought from the itching", "itching has increased dramatically" and "noticed as of late there is a larger pattern of bruising/patching that is bruised" required physician office visit. Clinical course: After his 2nd dose, he thought itching was a side effect and he has that on file and after that, now it is probably to the top level of boosters that he has had and where he is supposed to be and the condition of itching has increased dramatically and he has the skin condition to his forearms and it accelerated enough that it looks like if you are on a blood thinner where you have those kind of skin necrosis only he is not on a blood thinner. He is seeing a dermatologist. The itching did not start until the 2nd dose for the itching and now this skin pattern where it is easy to bleed started much later and he has patching that was there he thought from the itching. The itching increased dramatically and he does not know when it began to increase dramatically but guesses it is when he first noticed it was just there and did not notice it being increased but noticed as of late there is a larger pattern of bruising, bleeding and patching that is bruised.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300290354 same patient/vaccine, different dose/event;US-PFIZER INC-2021412848 same patient/vaccine, different dose/event;US-PFIZER INC-202300290360 same patient/vaccine, different dose/event;US-PFIZER INC-202300290361 same patient/vaccine, different dose/event;
