[Dermatology] Atlas of Dermatoses Resulting from Physical Factors (part 1)

These are pictures of Dermatoses Resulting from Physical Factors (Part 1). This is a part in Dermatoses Resulting from Physical Factors of the Andrews' Diseases of the Skin Clinical Atlas 1st Edition 2018 book

This chapter catalogues many examples of how the skin reacts to the external environment from which it protects the body. Exposure to physical factors such as heat, cold, moisture, ultraviolet light, radiation, mechanical trauma and imbedded foreign bodies can manifest as uniquely patterned skin fndings.

Of particular note are the many examples of photodistributed eruptions, symmetrically involving the face, chest, dorsal hands and forearms, as this pattern can be an important physical exam clue to one of many specifc photosensitive conditions. Those who spend signifcant amounts of time outdoors are particularly susceptible to acute and  chronic sun damage and may also sustain temperaturerelated (cold or hot) injuries at acral sites.

The distribution of mechanical injuries and foreign body reactions, however, is usually asymmetric. In this chapter, appreciate the geometric shapes and unnatural confgurations that can be produced on the skin as a result of physical abuse, radiotherapy or phytophotodermatitis. The patient history, and at times tissue analysis, can help to confrm the diagnosis that was suspected after a thorough physical

examination.

This portion of the atlas features examples of dermatoses and skin lesions resulting from physical factors.
