Erythema Nodosum - The eruption of red nodules along the top surfaces of the lower legs (shins). Erythema nodosum is nearly always a symptom of an underlying condition, often a streptococcal INFECTION, and represents INFLAMMATION of the fatty tissue at the foundation of the SKIN. Other symptoms include FEVER, PAIN and swelling in the joints, and generalized discomfort and malaise. Erythema nodosum occurs most commonly in young adults between the ages of 18 and 30.

Symptoms of Erythema Nodosum and Treatment

The initial eruption of nodules may clear in six to eight weeks, though outbreaks tend to recur over months to years. Over the course of HEALING the nodules change color from their original bright red to bluish red and ultimately yellow, resembling bruises, before fading completely. The doctor diagnoses erythema nodosum primarily on the basis of its appearance, though may run BLOOD tests to look for evidence of AUTOIMMUNE DISORDERS or infection that may underlie the outbreak. Treatment targets the underlying cause and may include ANTIBIOTIC MEDICATIONS when there is infection or anti-inflammatory agents such as NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS) to relieve swelling, pain, and fever.

Xanthoma definition

The Integumentary System |

Xanthoma is a fatty deposit that forms a benign (noncancerous) LESION beneath the SKIN, though also may occur in other tissues. Xanthomas develop in people who have chronic, untreated HYPERLIPIDEMIA (elevated BLOOD cholesterol and triglycerides levels). In their most common form, xanthomas appear as yellowish blebs beneath the skin, typically rounded or

Wrinkles treatment

The Integumentary System |

Wrinkles are furrows or channels in the SKIN, typically resulting from repeated movements, such as facial expressions (for example, crow’s feet and laugh lines), or from long-term exposure to sun and wind. Aging is the single-most significant factor that causes wrinkles. Wrinkles increase with age as the skin loses collagen and subsequently

Whitlow - herpes

The Integumentary System |

Whitlow is an INFECTION at the end of the finger, or less commonly the end of a toe, that contains pus and is very painful. The area is inflamed, enlarged, erythematous (reddened), and often oozing. A common cause of whitlow is infection with the HERPES SIMPLEX VIRUS (HSV), conveyed to the finger via contact with infectious secretions from oral herpes

Wheal - raised, blisterlike lesion on the skin

The Integumentary System |

Wheal is a raised, blisterlike LESION on the SKIN that usually results from an intradermal injection such as for ALLERGY skin testing or the tuberculin skin test. Wheals also may occur in response to insect stings and topical allergic reactions (URTICARIA or hives). Wheals associated with urticaria typically itch, sometimes intensely. Wheals usually do not

Wart - causes, symptoms and removal

The Integumentary System |

What are Warts and What Causes Warts Wart is a growth, typically rough and raised, that appears on the SKIN. The HUMAN PAPILLOMAVIRUS (HPV), which has numerous strains, causes common warts as well as variations including genital warts (a common sexually transmitted disease) and plantar warts which appear on the soles (plantar surfaces) of the feet. Because

Vitiligo disease - symptoms, treatment and causes

The Integumentary System |

Vitiligo - a condition of hypopigmentation in which melanocytes die in patches of SKIN, leaving macules that are pale and depigmented. Dermatologists believe vitiligo is an autoimmune disorder in which the IMMUNE SYSTEM produces antibodies that attack melanocytes, the skin cells responsible for producing pigment. Vitiligo affects people of all races and

What is Vesicle and definition

The Integumentary System |

Vesicle is a small, blisterlike LESION on the SKIN that contains serous fluid. Vesicles typically occur in clusters and indicate INFECTION, such as with HERPES SIMPLEX VIRUS (HSV), or irritation, such as results from contact with poison ivy. Skin vesicles often hurt or itch. Treatment may include topical medications to relieve discomfort, with oral

Urticaria - acute/chronic - definition, causes, treatment and complications

The Integumentary System |

What is Urticaria and Definition Urticaria is the clinical term for hives, an outbreak of wheals on the SKIN’s surface. Acute urticaria, which comes on suddenly, typically signals a HYPERSENSITIVITY REACTION. The wheals contain fluid the IMMUNE RESPONSE draws from the cells of the skin. They itch, often intensely (PRURITUS), and may appear and recede

Toxic Epidermal Necrolysis - Stevens Johnsons Syndrome

The Integumentary System |

Toxic Epidermal Necrolysis is a life-threatening inflammatory condition affecting the SKIN and underlying connective tissues, also called Stevens-Johnson syndrome. Toxic epidermal necrolysis usually results as an adverse DRUG reaction though may occur as a complication of INFECTION or CANCER. Doctors believe toxic epidermal necrolysis develops when an

Tissue Expansion

The Integumentary System |

What is Tissue Expansion Tissue Expansion is a method for growing additional SKIN to use for autologous (self) skin grafts. Autologous grafts have the best rate of success when transplanted because they are native to the body and present no risk for graft rejection. Tissue expansion is a common method for many reconstructive surgery procedures, though
