They are common lesions that can have their origin in the outermost layer of the skin (epidermis), for example seborrheic keratoses or epidermal nevi; middle layer (dermis) such as skin tags, also called fibropapillomas, or in the deeper layer (subcutaneous cellular tissue) such as lipomas, to name the most common examples.
Seborrheic keratoses are benign lesions with a warty appearance and a brownish-black color that can appear on the scalp, face and body. It is more common to observe after 40 years of age.
Skin tags are small skin-colored or brownish elevations located most frequently in folds: neck, armpits and groin. They usually appear during puberty and increase in size during pregnancy.
Epidermal nevi are warty-looking moles that are usually present from a person’s birth, but become more evident as the person develops. They can be observed in patients of any age and sex.
Lipomas are tumors that originate from adipocytes, which are the cells that store fat under the skin. They are generally diagnosed with the naked eye and palpation in the office, but in some cases they can simulate other types of lesions, both benign and malignant, and the help of diagnostic images such as ultrasound is necessary to ensure the diagnosis.
