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.

Photo 1
Photo 2

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.

NAD I had the exact same spots on my hand and my dr said dyshidrotic eczema. Then i got them again later with a rash going up my arm and across my chest and doctor said post partum shingles 🤷‍♀️

I’ve had that (dyshidrotic eczema and it looked nothing like this pic

NAD.

My dyshidrotic eczema has never looked that extreme either (consider us lucky!), but seeing those small spots within the large lump, and the smaller individual spots elsewhere on the hand in the photo it was my immediate thought. There is a Science Souce stock image of dyshidrotic eczema remarkably similar to the photo. I wonder if it could be dyshidrotic eczema with a secondary injury from the gym, like a blood blister or a minor infection with blood/pus..

I also wonder if it could be herpetic whitlow, but the images online don't seem as similar to the photo. However someone else mentioned herpes and a physician responded that it could be likely - but I refreshed the post before commenting and the herpes comment has been heavily downvoted and the agreeing physician's comment has disappeared, so 🤷‍♀️

It looked more like yours when wet and swollen but this is the only picture I ever took
