|
Acanthosis nigricans - The clinical hallmark is development of gray-brown, velvety plaques that may start as a dirty appearance. The hyperpigmentation is later accompanied by hypertrophy, increased skin markings, and papillomatosis.
|
|
|
Acne vulgaris - Acne vulgaris is the most common cutaneous disorder in the United States, affecting more than 85% of adolescents. Acne is a disorder of the pilosebaceous follicle that involves proliferation of the keratinocytes at the opening of the follicle; increased production of sebum, stimulated by androgens, which combines with keratinocytes to plug the follicular opening; growth of Propionibacterium acnes, an anaerobic diphtheroid normally found on the skin; and inflammation from bacterial activity and release of free fatty acids and enzymes from activated neutrophils. Cosmetics, humidity, heavy sweating, and stress are contributing factors.
|
|
|
Actinic keratosis - Superficial, flattened papules covered by a dry scale. Often multiple; can be round or irregular; pink, tan, or grayish. Appear on sun-exposed skin of older, fair-skinned people. Though benign, 1 of every 1000 per year develops into squamous cell carcinoma (suggested by rapid growth, induration, redness at the base, and ulceration). Keratoses on face and hand, typical locations, are shown.
|
|
|
Acute otitis media - Acute otitis media with purulent effusion is caused by bacterial infection. Symptoms include earache, fever, and hearing loss. The eardrum reddens, loses its landmarks, and bulges laterally, toward the examiner’s eye. Here the eardrum is bulging, and most landmarks are obscured. Redness is most obvious near the umbo, but dilated vessels can be seen in all segments of the drum. A diffuse redness of the entire drum often develops. Spontaneous rupture (perforation) of the drum may follow, with discharge of purulent material into the ear canal. Hearing loss is of the conductive type. Acute purulent otitis media is much more common in children than in adults.
|
|
|
Alopecia areata - Clearly demarcated round or oval patches of hair loss, usually affecting young adults and children. There is no visible scaling or inflammation.
|
|
|
Anal fissure - An anal fissure is a very painful oval ulceration of the anal canal, found most commonly in the midline posteriorly, less commonly in the midline anteriorly. Its long axis lies longitudinally. There may be a swollen “sentinel” skin tag just below it. Gentle separation of the anal margins may reveal the lower edge of the fissure. The sphincter is spastic; the examination is painful. Local anesthesia maybe required.
|
|
|
Angioedema - A diffuse, nonpitting, tense swelling of the dermis and subcutaneous tissue. It develops rapidly, and typically disappears over subsequent hours or days. Although usually allergic in nature and sometimes associated with hives, angioedema does not itch. Recurrent large circumscribed areas of subcutaneous or mucosal edema of sudden onset, usually disappearing within 24 hours; frequently, an allergic reaction to foods or drugs
|
|
|
Angular cheilitis - Angular cheilitis starts with softening of the skin at the angles of the mouth, followed by fissuring. It may be due to nutritional deficiency or, more commonly, to overclosure of the mouth, as in people with no teeth or with ill-fitting dentures. Saliva wets and macerates the in-folded skin, often leading to secondary infection with Candida, as seen here.
|
|
|
Ankyloglossia-aka tongue tied: Partial or complete fusion of the tongue to the floor of the mouth; abnormal shortness of the frenulum linguae.
|
|
|
Cornel Arcus senilis - a white, gray, or blue opaque ring in the corneal margin (peripheral corneal opacity), or white ring in front of the periphery of the iris. It is present at birth, but then fades; however, it is quite commonly present in the elderly. It can also appear earlier in life as a result of hypercholesterolemia.
|
|
|
AV nicking - the phenomenon where, on examination of the eye, a small artery (arteriole) is seen crossing a small vein (venule), which results in the compression of the vein with bulging on either side of the crossing. This is most commonly seen in eye disease caused by high blood pressure
|
|
|
Bartholin cyst - Causes of a Bartholin’s gland infection include trauma, gonococci anaerobes like bacteroides and peptostreptococci, and Chlamydia trachomatis. Acutely, it appears as a tense, hot, very tender abscess. Look for pus coming out of the duct or erythema around the duct opening. Chronically, a nontender cyst is felt. It may be large or small.
|
|
|
Blepharitis - an eye condition characterized by chronic inflammation of the eyelid
|
|
|
Bulla - Greater than 1 cm. A blister is a small pocket of fluid within the upper layers of the skin. Blisters can be filled with blood (known as blood blisters) or with pus (if they become infected). However, most blisters are filled with a clear fluid called serum. A blister usually forms because the outer layer of the skin has become damaged. Fluid collects under the damaged layer of skin, cushioning the tissue underneath, protecting it from further damage and allowing it to heal.
|
|
|
Cataract - Opacities of the lenses visible through the pupil; most common in old age.
|
|
|
Cavernous hemangioma - is a vascular disorder of the central nervous system that may appear either sporadically or exhibit autosomal dominant inheritance. deep cutaneous hemangioma with dilated vessels on gross and microscopic examination

|
|
|
Chondritis – Inflammation of cartilage.
|
|
|
Clubbing - Clinically a bulbous swelling of the soft tissue at the nail base, with loss of the normal angle between the nail and the proximal nail fold. The angle increases to 180°or more, and the nail bed feels spongy or floating. The mechanism is still unknown but involves vasodilatation with increased blood flow to the distal portion of the digits and changes in connective tissue, possibly from hypoxia, changes in innervation, genetics, or a platelet-derived growth factor from fragments of platelet clumps. Seen in congenital heart disease, interstitial lung disease and lung cancer, inflammatory bowel diseases, and malignancies.
|
|
|

|
|
|
Crust - The dried residue of skin exudates such as serum, pus, or blood
|
|
|
Cupping - The physiologic cup is a small whitish depression in the optic disc, from which the retinal vessels appear to emerge.

When the size of the cup increases (normal cup:disc = 1:2)
|
|
|

|
|
|
Dupuytren’s contracture - The first sign of a Dupuytren’s contracture is a thickened plaque overlying the flexor tendon of the ring finger and possibly the little finger at the level of the distal palmar crease. Subsequently, the skin in this area puckers, and a thickened fibrotic cord develops between palm and finger. Flexion contracture of the fingers may gradually ensue.
|
|
|
Ectropion - In ectropion the margin of the lower lid is turned outward, exposing the palpebral conjunctiva. When the punctum of the lower lid turns outward, the eye no longer drains satisfactorily, and tearing occurs. Ectropion is more common in the elderly.
|
|
|
Eczema - a group of medical conditions that cause the skin to become inflamed or irritated
|
|
|
Enophthalmos - the posterior displacement of the eyeball within the orbit due to changes in the volume of the orbit
|

Hemorrhoid - External hemorrhoids are dilated hemorrhoidal veins that originate below the pectinate line and are covered with skin. They seldom produce symptoms unless thrombosis occurs. This causes acute local pain that increases with defecation and sitting. A tender, swollen, bluish, ovoid mass is visible at the anal margin. Internal hemorrhoids are enlargements of the normal vascular cushions located above the pectinate line. Here, they are not usually palpable. Sometimes, especially during defecation, internal hemorrhoids may cause bright-red bleeding. They may also prolapse through the anal canal and appear as reddish, moist, protruding masses, typically located in one or more of the positions illustrated.

Kaposi’s sarcoma - The deep purple color of these lesions, although not necessarily present, strongly suggests Kaposi’s sarcoma. The lesions may be raised or flat. Among people with AIDS, the palate, as illustrated here, is a common site for this tumor. This malignant tumor may appear in many forms: macules, papules, plaques, or nodules almost anywhere on the body. Lesions are often multiple and may involve internal structures. On left: ovoid, pinkish red plaques that typically lengthen along the skin line may become pigmented. On right: a purplish red nodule on the foot.
|
|
|
Keloid - A firm, nodular, hypertrophic mass of scar tissue extending beyond the area of injury. It may develop in any scarred area but is most common on the shoulders and upper-chest.
