A mole can be either subdermal (under the skin) or a pigmented growth on the skin, formed mostly of a type of cell known as a melanocyte. The high concentration of the body's pigmenting agent, melanin, is responsible for their dark color. Moles are a member of the family of skin lesions known as nevi (singular "nevus"), occurring commonly in ...
Congenital melanocytic nevus is a type of melanocytic nevus, the medical term for what is colloquially called a "mole", found in infants at birth. Occurring in about 1% of infants in the United States, it is located in the area of the head and neck 15% of the time, but may occur anywhere on the body.
Others may warrant more thorough examination and biopsy for histopathological examination (looking at a sample of skin under a microscope to detect unique cellular features). For example, a clinician may want to determine whether a pigmented nevus is a type of melanocytic nevus, dysplastic nevus, or melanoma as some of these skin lesions pose a ...
In dermatology, a mole map is a medical record which records an image and the location of lesions and/or moles, or dark spots on the human body.Such a record is useful for diagnosis of cancer a priori or as a baseline which can be compared against later images to determine when there has been a visual change which may indicate cancer.
Mongolian spot is a congenital developmental condition—that is, one existing from birth—exclusively involving the skin.The blue colour is caused by melanocytes, melanin-containing cells, that are usually located in the surface of the skin (the epidermis), but are in the deeper region (the dermis) in the location of the spot.

The etymology of the word "morphology" is from the Ancient Greek μορφή (morphḗ), meaning "form", and λόγος (lógos), meaning "word, study, research". [2] [3]While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist ...
Eimer's organs are organs for the sense of touch, shaped like bulbous papillae, formed from modified epidermis.First isolated by Theodor Eimer from the European mole in 1871, these organs are present in many moles, and are particularly dense on the star-nosed mole, which bears 25,000 of them on its unique tentacled snout.
