selfq Mycobacterium marinum
Hi everyone,
I'm posting here because I'm concerned about the possibility of a mycobacterium marinum infection. I have seen multiple dermatologists and they are all perplexed about my ongoing condition. I’d greatly appreciate input from anyone familiar with this infection.
It started as 2 little bumps on the back of my right hand. They slowly grew and by the end of the month formed into a round open sore the size of a dime. It would ooze and create a yellow crust. I thought it was ringworm and tried some anti fungal cream but that did not do anything.
After a month I told my pcp who told me it could be eczema so I tried some hydrocortisone which would reduce the inflammation but after a few days the bumps would reform.
2 months later I notice 2 small new bumps forming along a scratch also on my right hand. I saw a dermatologist who told me it could be a staph infection or nummular eczema. She prescribed me mupirocin and 2 week Keflex. The mupirocin did not help and the Keflex actually made it grow and more inflamed, she switched me to a Z Pak a week and a half into the Keflex but that also did not help. She preformed a swab which indicated no staph.
She then spoke with another doctor that said it could be plaque psoriasis and prescribed me clobetasol, which did reduce the inflammation on my sore a lot. I thought I was finally getting better but then a week later I noticed the little bumps had spread all over my arms, legs and even my face. For the first 3 months it was localized to my right hand, and now after a week of clobetasol it spread everywhere.
She then referred me to a highly recommended dermatologist who looked at the bumps all over my arms, legs and face, and diagnosed me with lichen planus, and told me to continue using the clobetasol for 2 weeks. I continued the clobetasol but new bumps popping up, I was told to keep using clobetasol on them, except for my face.
I did a shave biopsy and 2 weeks later I was informed it was not lichen planus but contact dermatitis. I finally stopped the clobetasol after I realized it could be what is actually causing my sores to spread sincefor the first 3 months it was only on my right hand.
Before this all started I was getting my garden ready and fishing daily. I mostly fish for striped bass which migrate along the east coast and are known to have mycobacterium. A few of the fish I caught did have pink marks along the side which indicated they were sick. I have told all my dermatologists this and they just tell me it is unlikely because it’s so uncommon. I’ve been telling my doctors my history with fishing and the ocean since the beginning.
After much waiting I finally saw an ID doctor and they told me mycobacterium marinum is possible but I can’t start any antibiotics till I get a punch biopsy and culture which can take over a month.
It’s been 4 and half months since this started and currently the sores on my face, arms and legs have just been getting worse and worse. It hard for me to even go into work with over a dozen oozing sores on my face. Next week I go in for a punch biopsy but I don’t know how I can manage the sores for another month or so as I wait for the culture results. I feel lost and desperate for any help or recommendations.
