Slide 4-

Seborrheic Keratosis More common in the elderly Often pigmented Variable size “Barnacle-like” appearance Usually asymptomatic
Slide 5-

Stucco Seborrheic Keratosis Primarily on the extremities, especially distally Often small 2-3mm white plaques that are easily lifted off
Slide 6-

Slide 7-

Keratoacanthoma Rapidly evolving tumor, often in the matter of weeks, possibly of viral origin Composed of keratinizing squamous cells More common in fair skinned, elderly people May resolve spontaneously over a period of 2 to 12 months
Slide 8-

Epidermal Nevus
Slide 9-

Nevus Comedonicus
Slide 10-

ppt slide no 10 content not found
Slide 11-

Acrochordon (Skin tags) Occur in approximately 25% of males and females Occur in the axilla, neck and inguinal region Increase with age beginning the 20s up into the 50s Few to multiple
Slide 12-

Benign Tumors Derived from the Epidermal Appendages
Slide 13-

Epidermoid Cyst
Slide 14-

Epidermoid Cyst Common, affecting young and middle age adults Usually seen on the head, neck and trunk Often can identifiy a punctum Cyst contains keratin
Slide 15-

Pilar Cysts
Slide 16-

ppt slide no 16 content not found
Slide 17-

Sebaceous Hyperplasia Found on the face Singular to multiple in number Usually 2-3mm up to 6mm with umbilication Often begin to appear in the 30s and increase with age
Slide 18-

Nevus Sebaceous of Jadassohn
Slide 19-

Hidrocystoma
Slide 20-

ppt slide no 20 content not found
Slide 21-

Syringomas Sweat duct tumors More common in females May first appear in adolescence, but more often in the third decade Found around eyelids and are skin colored to yellow in appearance
Slide 22-

Eccrine Poroma Tumor arising from the eccrine duct epithelium Often on the soles and palms Tend to be moist, red and exophytic
Slide 23-

ppt slide no 23 content not found
Slide 24-

Clear Cell Acanthoma A scaly plaque or nodule that has an accumulation of glycogen containing cells Most common on the lower limbs Usually solitary and may persists for years
Slide 25-

Benign Melanocytic Tumors
Slide 26-

Nevus A benign cluster of melanocytic cells arising as a result of proliferation of melanocytes at the dermo-epidermal junction. These may all remain in contact with the basal layer (the junctional nevus) or may become dettached from the basal layer and lie free in the dermis (the compound and intradermal nevus).

Halo Nevus
Slide 31-

Spitz Nevus A compound nevus seen most commonly in children and with lesser frequency in adults They appear suddenly and the color is caused by increased vascularity Its pathological features can be difficult to distinguish from malignant melanoma
Slide 32-

Blue Nevus An area of blue-black dermal pigmentation produced by an aberrant collection of pigment producing melanocytes The brown pigment absorbs the longer wavelength of light and scatters blue light (Tyndall effect) Extend into the deep dermis, often occur on extremities and the dorsum of the hand
Slide 33-

Benign Tumors Derived from Mesodermal Tissue
Slide 34-

Slide 35-

Dermatofibroma Can occur on any part of the body, most common on the lower extremities, to a lesser degree on the upper extremities and trunk May be single or multiple Usually pink or brown Commonly 6mm or less Hard consistency
Slide 36-

Fibrous Papule Small facial papule with a fibrovascular content Usually seen on or next to the nose Usually singular but on occasion can be multiple
Slide 37-

Slide 38-

Keloid An exaggerated reparative fibroblastic response to injury of the skin Genetic tendency Most commonly found on the ears, neck and trunk
Slide 39-

Cherry Angioma
Slide 40-

ppt slide no 40 content not found
Slide 41-

Pyogenic Granuloma A vasular nodule that develops rapidly, with a glistening moist surface Often may appear at a site of recent trauma Composed of proliferating capillaries in a loose stroma Bleeds easily
Slide 42-

Lipoma
Slide 43-

Premalignant Tumors
Slide 44-

ppt slide no 44 content not found
Slide 45-

Actinic Keratosis Hyperkeratotic lesions occurring in sun exposed adult skin May exist in a premalignant state for years Often begin as an area of increased vascularity with the surface becoming rough May progress to squamous cell carcinoma
Slide 46-

Actinic Cheilitis
Slide 47-

ppt slide no 47 content not found
Slide 48-

Squamous Cell Carcinoma in situ (Bowen’s Disease) A persistent, progressive, nonelevated, red, scaly or crusted plaque An intraepidermal proliferation on exposed and nonexposed areas of the body Often mistaken for eczema or psoriasis
Slide 49-

Epidermal Malignancies
Slide 50-

Superficial Basal Cell Carcinoma
Slide 51-

Basal Cell Carcinoma Most common form of skin cancer Usually appears on sun damaged skin Pearly appearance with superficial telangiectasias Rarely metastasizes Derived from basal cell layer of the epidermis
Slide 52-

Pigmented Nodular Basal Cell Carcinoma
Slide 53-

Sclerosing Basal Cell Carcinoma

Slide 56-

Squamous Cell Carcinoma
Slide 57-

Squamous Cell Carcinoma Often in older fair skinned persons Hyperkeratotic and often ulcerates SCC is separated into two groups based on malignant potential
Slide 58-

Slide 59-

In Situ Malignant Melanoma Melanoma cells confined to the epidermis Lack in invasion may persist for months to years Simple excision is often curative
Slide 60-

Superficial Spreading Melanoma
Slide 61-

Superficial Spreading Melanoma Most common in middle age Develops anywhere on the body, back in both sexes and legs in females Haphazard combination on colors but may be uniformly brown or black
Slide 62-

Acral Lentinginous Melanoma Most common in blacks and orientals Appears on the palms, soles terminal phalanges and mucous membranes The tumor is very aggressive and metastasizes early
Slide 63-

Nodular Melanoma Occurs in the fifth or sixth decade More frequent in males with a ratio of 2:1 Found anywhere on the body Most frequently misdiagnosed because it can resemble a blood blister, hemangioma, dermal nevus or polyp
Slide 64-

Amelanotic Melanoma
