Itchy Purple Bump Appeared On Thumb. Should I Consult A Dermatologist?
Thanks for writing to us.
This purplish lesion could be anything. It could be a haematoma or bruise due to some injury, a Pyogenic granuloma, vasculitis lesion,cherry angioma, angiokeratoma, a nevi or a melanoma. Melanoma usually appears as an irregular pigmented lesion and is quite commonly confused with a bruise
As you can see the cause could be benign as well as something as sinister as a melanoma.
Dermatology is completely a visual field and no diagnosis can be surely suggested without clinically examining the lesion. As you would be away for a month, I would definitely suggest you to XXXXXXX a dermatologist near by to decide upon a possible diagnosis and treat the lesion appropriately.
Hope that helps. Should there be any query, feel free to write back.
Regards.
