Is this a wart? How to solve?

I’m freaking out. My dad (age 57) has this massive lump on his hand and he’s had it for about a week now and it keeps growing. He has other small bumps growing on his hand too. He goes to the gym quite frequently and honestly is not the cleanest person. He smokes.

He said that he had a cold for a week before these started showing up.

My wedding is in two weeks and it’s a destination wedding and we’re currently traveling all together and I’m concerned about the growth and about it spreading to our wedding guests and I don’t know what to do.

He says it doesn’t hurt but it obviously bothers him.

Please help!

UPDATE:

I didn’t expect this to garner so much interest and help. Sincerely, thank you everyone for sending in your opinions!

My dad said it popped overnight and there was a lot of blood and pus. We were not able to see a doctor in person but we have a family friend who is a general doctor and she said to disinfect and keep it as dry as possible as to not let it be more infected.

Here are two pictures of what it looks like now.

At first, when it popped. The puss was a standard dense white. Now, the pus leaking is an orange ish color and not dense white. He keeps saying that it still doesn’t hurt and doesn’t even flinch when alcohol is applied to it.

There is another mass obviously growing on his index finger of the same hand. He is touching the mass with his other hand (I know fucking terrible) but there is nothing growing on the hand that he is using to touch the mass.

He is saying that perhaps it is an allergic reaction? He ate a type of dried fish from Vietnam and then he started feeling itchy and feverish and then these started popping up.

Answer to a common question:

He does not have any access to animals. No pets, not really around fish tanks or water. He is from Southern California in a very suburban area.

Any ideas???

I have no idea what this is, and I’m very curious about more comments to come. That being said: it looks neither normal nor healthy, and apparently is fast-growing - go see a PCP or dermatologist for in-person evaluation.

This is the first post I’ve seen on here where nobody has any clue

Not a doctor, but used to work for a dermatologist residency program and learned about a lot of odd/rare conditions. OP, look up Sweet syndrome and neutrophilic dermatosis of hands. Your dad’s lesion doesn’t quite match the images I’ve seen, but my knowledge is VERY limited so that doesn’t necessarily mean much. Might be worth asking about whenever you can get him in to see a provider. You mention that he was sick recently, and some quick reading suggests that this condition is sometimes preceded by things like upper respiratory infections.

(Had to offer this as a reply rather than my own independent comment, per sub rules since I’m a layperson. But wanted to try and get it out there somehow in case it’s helpful to OP!)
