Tineas Capitis
Sudden appearance of a sharply circumscribed, ROUND or oval balding patch, usually with SMOOTH, soft, hairless skin underneath.
Alopecia areata
Regrowth occurs after illness or discontinuation of toxin. Mainly ocuur due to Chemo treatment.
Toxic Alopecia

Sarcoma Caposi
Traumatic sel-induce hair loss usually the result of compulsive twisting or plucking.
Trichotillomania
Head Lice
Pediculosis Capitis
Multiple pustules, “whiteheads,” with hair visible at CENTER and erythematous base. Usually on arms, legs, face, and buttocks
Folliculitis
Red, swollen, tender inflammation of the nails folds.
Paronychia
Acute version is usually a bacterial infection; chronic version is most often a fungal infection from a break in the cuticle in those who perform “WET” work.
Paronychia
A depression across the nail that extends down to the nail bed. Occurs with any trauma that temporarily impairs nail formation, such as acute illness, toxic reaction, or local trauma
Beau’s line
Red-brown linear STREAKS, embolic lesions, occur with subacute bacterial ENDOCARDITIS; also may occur with minor trauma
Splinter hemorrhages
Inner edge of nail elevates; nail bed angle is GREATER than 180 degrees.
Clubbing of the nails.
This is a slow, persistent fungal infection of fingernails and, more often, toenails, common in older adults.- Apearing in the NAIL PLATES
Onycholysis
The inner basal cell layer of the epidermis that forms new skin cells. made up of keratin, the fibrous protein, melanin is interspersed along this layer
Stratum germinativum
the outer horny layer of the epidermis formed by the migrated, flattened cells of the basal layer. this layer consists of dead keratinized cells that are interwoven and closely packed.
Stratum corneum
Protion of hair that is below the surface, embedded in the follicle
Root
Located in the expanded areas where the new cells are produced at a high rate
Bulb matrix
Fine, faint hair that covers most of the body
Vellus
Darker, thicker hair that grows on the scalp and eyebrows and, after puberty, on the acillae, pubic area, and the face and chest in male
Terminal hair
Oils and lubricates the skin and hair and forms an emulsion with water that retards water loss from the skin.
Sebum
Coiled tubules that open directly onto the skin surface and produce a dilute saline solution called sweat.
Eccrine glands
Producers of a thick, milky secretion that opens directly into the hair follicles. located in the axillae, anogenital area, nipple, and naval
Apocrine glands
Become active during puberty, and are stimulated with emotion and sexual stimulation
Apocrine glands
White opaque semilunar area at the proximal end of the nail.
Lanula
Fine downy hair of the newborn
Lanugo
Thick, cheesy substance present at birth that is made up of sebum and shed epithelial cells
Vernix Caseosa
An increased pigment in the areolae and nipples, vulva, and sometimes in the midline of the abdoment because of the change in hormone levels in pregnant women
Linea nigra
Increased pigmentation in the face because of a change in hormone levels in pregnant women also know as the “mask of pregnancy”
Chloasma
A dark red discolored area found in elderly because of their decreasing vascularity and increasing fragility of skin
Senile purpura
Itching
Pruritus
Complete absennce of melanin pigment in patchy areas of white or light skin on the face, neck, hands, feet, body folds, and around orifices
Vitiligo
ephilides
Freckels
Mole
Nevus
Profuse perspiration
Diaphoresis
A common variation in about half of newborns that causes yellowing of the skin, sclera, and mucus membranes
Physiological Jaundice
Caused by increased sebaceous gland activity in adolescence, can include milder open/closed comedones (white and black heads),
Acne
Lesions that are raised, thickened aras of pigmentation that look crusted, scaly, and warty. there are many different forms, caused by/no relation to the amount of sun exposure, malignant or benign. common in older adults
Keratoses
Acrochordons
Skin tags
Raised yellow papules that have a central dpression. common on oler men’s foreheads, nose, or cheeks
Sebacceous hyperplasia
3 layers of the skin
- Epidermis
- Dermis
- Subcutaneus
Dermis is most made out of?
Connective Tissue or Collagen
Subcutaneous layer is made out of ?
Adipose tissue
Wrinkling occour due to?
Loss of collagen, elastin, subcutaneous far, and a reduction of muscle tone
