What am I?
Nodulocystic acne
Acne conglobata In this severe nodulocystic acne, there are large confluent nodules and cysts forming linear mounds that correspond to interconnecting channels. There is pustulation, crusting, and scarring. Lesions are very painful.
Acne conglobata on the trunk Inflammatory nodules and cysts have coalesced, forming abscesses that can lead to ulceration. There are many recent red scars following resolution of inflammatory lesions on the entire chest but also on the back
Erythematous rosacea (stage I) The early stages of rosacea often present by episodic erythema, “flushing and blushing,” which is followed by persistent erythema caused by multiple tiny telangiectasias, resulting in a red face.
Rosacea Moderate rosacea in a 29-year-old female with persistent erythema, telangiectasia, red papules (stage II), and tiny pustules
Rosacea (stages II–III) Telangiectasia, papules and pustules, and some swelling in a 50-year-old woman. There are no comedones.
Papulopustular rosacea (stage III) In this 68-year-old female, rosacea involves almost the entire face, sparing only the upper and lower lip and temples. Papules and pustules have coalesced—again no comedones—and have already led to some swelling of the cheeks, which present “solid” edema
Rosacea (stage III) Here the persistent “solid” edema of the nose, forehead, and parts of the cheeks is the leading symptom. Papules, pustules, and crusted pustules are superimposed on this persistent edema. The enlarged nose feels rubbery and already represents rhinophyma. Note also blepharophyma of left upper eyelid
Perioral dermatitis Moderate involvement with early confluence of tiny papules and a few pustules in a perioral distribution in a young woman. Note typical sparing of the vermilion border (mucocutaneous junction)
Perioral dermatitis Preferential location around the mouth and nasolabial folds and cheeks. This 38-year-old woman has been treated with fluorinated corticosteroids that led to a worsening of the conditio
Periorbital dermatitis Note presence of tiny papules and a few pustules around the eye. This is a much less common site than lesions around the mouth.
Miliaria crystallina Tiny, superficial, clear vesicles on the trunk after excessive sweating
Chromhidrosis Note blue to black droplets of lipofuscin stained apocrine sweat in the glandular duct orifices. There is also a bluish sheen imparted to the entire axillary skin by lipofuscin in the glands deeper down in the tissue
Hidradenitis suppurativa Many black comedones, some of which are paired, are a characteristic finding associated with deep, exquisitely painful abscesses and old scars in the axilla
Hidradenitis suppurativa Multiple bulging and depressed scars, draining sinuses and larger ulcer in the axilla of a 24-year-old male
Hidradenitis suppurativa Severe scarring on the buttocks, inflammatory painful nodules with fistulas, and draining sinuses. When the patient sits down, pus will squirt from the sinus openings
Hidradenitis suppurativa The entire perigenital and perianal skin as well as the buttocks and inner aspects of the thighs are involved in this 50-year-old male. There is considerable inflammation, and pressure releases purulent exudate from multiple sinuses. The patient had to wear a large diaper, because whenever he was seated, secretions would squirt from the sinuses
macule, petechiae
Patch, fixed drug eruption
Papule, lichen nitidus
Plaque, psoriasis.
nodule, lymphoma cutis
