ABSTRACT
The respiratory system is closely related to skin, as both of these systems are the first ones to face external insult or pathogens. Various pulmonary disorders have characteristic cutaneous manifestations such as yellow nail syndrome, sarcoidosis, and certain vasculitis syndromes, whereas other general features such as clubbing and cyanosis can be seen in many respiratory disorders in addition to those affecting other systems including the cardiovascular system. Similarly, many dermatoses are known to affect the lungs primarily or are complications. Skin and the neurological system share a common embryonic origin, thereby many genetic disorders affecting the skin also involve the neurological system and are commonly referred to as neurocutaneous syndromes. Many of such genodermatoses, also called phakomatoses, in addition to a number of other acquired infective, inflammatory, or malignant conditions affecting the skin, can present with a neurological emergency, such as stroke or seizure. The lungs and the central nervous system can commonly be involved in dermatological emergencies. Similarly, many neurological and pulmonary emergencies can have varied cutaneous manifestations. Knowledge of these features can help all specialists involved to manage these emergencies in a much better way.
