Local and Central IRBs/IECs There are two types of IRBs/IECs: local and central. Local IRBs/IECs are functions of the academic institutions that conduct research and review only their trials, while central IRBs/IECs provide review services for multiple entities.
Groin and genital lesions resembling skin tags may actually be genital warts or condyloma. A biopsy would help diagnose which of these growths are not skin tags. Very rarely, a basal cell skin or squamous cancer or melanoma may mimic a skin tag, but this is very uncommon.
Skin tags are one of many forms of noncancerous skin growths that are abnormal accumulations of different types of skin cells. This group also includes moles, lumps of fatty material called lipomas, and red or purple discolorations called angiomas. They may be present at birth or develop later. Skin tags are soft and usually small, but if left to grow for years they can become an inch or more long. They are usually flesh-colored or a little darker. They typically grow on the neck, underarms and groin, but can be found in many other parts of the body as well.
