Hi Dr. Jankicevic, could you check the picture I have uploaded.
Thank you very much.
Welcome to the Dermatology Expert Forum!
Here is the list of several differential diagnoses to be looked into: angiokeratoma, inflamed viral wart or mollusca, granuloma annulare, syringoma, epidermoid cyst, angiofibroma, etc.
You mentioned that multiple doctors had looked at your lesion without establishing final diagnosis. In such a case (clinically inconclusive) performing a biopsy is completely justified and recommended, especially if a lesion is pigmented (rapidly expanding pigmented nevus for example).
Yes, there is an option to post photographs on your MedHelp profile page. Photographs of lesions can be useful if taken as clear close-ups.
Wishing You Optimal Health,
Dr Jasmina Jankicevic
