<s>[INST] i have a rough mole most circular in shape, light to slightly dark brown in color, rough and bump about the size of half a pencil eraser. it is red in the middle and often itches and feels strange. Like I said it is rough and bumpr unlike other moles that are smooth to the skin. It is located in the center of my chest between my deltoids... [/INST] HIThank for choosing HCMAs you described here the location of this lesion it seems it could be the wart, or a simple mole, the final diagnosis is depend upon the clinical examination, in either of conditions it need to be excised under local anesthesia and the specimen should be sent for hestopathological examination for differential diagnosis, better consult to some skin specialist for further advise, Have good day. </s>
