Hi there. I would require some history as regards the 'spots' before i attempt to opine. I have viewed your 4 attached photographs. You do say they are bilateral but all these snaps are of the left axilla (armpit). Could you perhaps upload one image of the right armpit as they may just be different conditions.
When did the rash start? (how long ago/?spreading/growing in size/number?)
Itchy/Burning/Tender? Symptoms
Was there any local minor trauma (eg shaving/waxing/lasers etc) prior to onset?
Was it following any deos/spray application to the area?
Do you have any blood(hematological) disorders & has there been any blood tests done in the recent past with regards to bleeding time/platelets more specifically?
Are there similar lesions in your groin/thigh regions?
Have you visited any doctor/dermatologist for this condition & been prescribed anything & does it work? What has the doctor told you it is?
Were the spots 'red' awhile ago with spreading margins & did they change colour to become 'purple' over the last few days/weeks?
Are you 'allergic' to anything at all...mediations/foods/dyes/food colouring or flavours?
Cheers. Await your response to my queries & will get back in time.

Hey XXXXXXX I empathise with your problem. One has to ensure that one's wife is always kept happy & understand you want this to go away. Here's what i think:
Your history & Clinical features & the fact that you have done an entire physical with all labs et al being normal suggest just one thing..it is a type of contact dermatitis or more specifically, from it's initial appearance, my first thoughts/gut instinct feel were FDE (fixed drug eruption). Now this is a misnomer...FDE does not relate only to 'drug's. It can be a skin reaction pattern (delayed hypersensitivity reaction) to almost any 'food or medication' including food colouring agents/additives etc & more commonly than not, the latter. Hence when one develops drug allergies, one must keep in mind the 'colour' of the tablet as often the dyes used in these are the ones that give rise to the allergy.
In your case, you clearly attribute the lesions onset to the use of the deo & i for one, always believe the patient knows best where these contact dermatitis/FDE is concerned.
The management:
(Prevention)Please figure out all the ingredinets (if you can) including colour et al in that deo stick & then avoid all tabs/colouring agents/foods etc having the same ingredients for at least 6 weeks. Then one may 'discretely' use a small miniscule quantity of the same & see if it recurrs....this is called the 'usage' test & is self explanatory.
(treatment)This is more difficult as it has been some time. Presently no point in topical cortisone creams unless there is some redness..if so, use a topical mixed cream (betamethasone-miconazole) combine to reduce any inflammation & in case any superadded fungal infection for 3-5 days & stop; Then switch to a pigment lightening cream : for awhile use a bioderma company product called Cicabio twice/daily for 2 weeks to promote regenration of the region; then switch to a south beach company formula for pigment lightening in 'sensitive' areas..this is what these are called & am sure your local pharmacist can help you.
Am afraid this is the best we can do for you online. Please review with this transcript & your local dermatologist @ ground 0 after 1 month if some pigmentation persists which may require the help of lasers that the dermatologist on the ground only can recommend after assessing the lesions. Remember to take photographs at weekly intervals to observe the progress.
I do hope I have been lucid, candid & objective in my assessment & have 'come up with something' tangible. If so, please do close this discussion & do give us your valuable feedback. I understand some other docs have commented on this particular issue & you are most welcome to collate the opinions & take an informed deciscion. Cheers XXXXXXX & good luck & hope your wife looses the pigmentation et al & all is well in the coming weeks!
