Answer 1

> skin lesions that are non cancerous skin growth

Question 2

Answer 2

> CHERRY HEMANGIOMA

> STRAWBERRY ANGIOMA

> PYOGENIC GRANULOMA

Question 3

CHERRY HEMANGIOMA

Answer 3

> increase w/ age
proliferation + dilated mature capillaries

CLINICAL FEATURES
> bright cherry red/ purple > dome shaped papules
> trunk + upper extremeties
> multiple lesions

DX
> clinical appearance of lesion

TX
> only if bleeding occurs / cosmetic reasons
> electrocauterisation
> vascular laser therapy

PROGNOSIS
> no malignant potential
> no spontaneous regression
> no prevention possible

Question 4

STRAWBERRY ANGIOMA

Answer 4

BENING VASCULAR TUMOR OF INFANCY + CHILDHOOD

Question 5

PYOGENIC GRANULOMA

Answer 5

> cause uknown
linked w/ trauma + pregnancy > reactive proliferation of capillary blood vessel

CLINICAL FEATURES
> soft, round, bright red tumors
> easy bleeding
> at site of injury on face/ hands

DIAGNOSIS
> based on clinical appearance
> rapid growth + easily injured/ bleeding surface

TREATMENT
> surgical excision

Question 6

HYPERTROPHIC SCARS

Answer 6

> high fibroblast proliferation + collagen production
due to > local + genetic factors
does not grow beyond boundaries of original lesion
regress spontaneously

CLINICAL FEATUES
> raised scar tissue
> erythematous
> pruritis

DIAGNOSIS
> clincal appearance of lesion
> px history of trauma/ surgery

TREATMENT
MEDICAL TX
» first line tx > intralesional steroid injection
» silicone gel sheets
» compression therapy

SURGERY
> cyrotherapy
> laser tx
> surgical excision combined w/ radiotherapy
> light therapy

Question 7

KELOID SCAR

Answer 7

> high fibroblast proliferation + collagen production
excessive tissue response > typically to small skin injuries
growth beyond boundaries of original lesion
does not regress spontaneously

CLINICAL FEATUES
> scar tissue of varying consistency > soft + hard > brownish/red
> pruritis
> pain
> MC > earlobes, face (cheeks), upper extremity, chest, neck

DIAGNOSIS
> clinical appearance of lesion
> px history of trauma/ surgery

TREATMENT
> same as hypertophic scar
> BUT no excision > it can reoccur after resection

Answer 8

IRREGULAR HYPERKERATOSIS + HYPERPLASIA OF EPIDERMIS
> due to > human papilomavirus

FLAT WARTS > verruca plana
> face, back of hand, legs
> flesh coloured, smooth papules, flat surface

PLANTAR WART (verruca plantaris)
> soles of feet
> flesh coloured, hyperkeratotic surface

DIAGNOSIS
> clinical appearance

TREATMENT
> salicylic acid
> daily application for few weeks
SURGERY
> cyrotherapy w/ liquid nitrogen
> surgical excision

PROGNOSIS
> healthy px achieve spontanous remission but warts may reoccurs
