Session 2 CM derm9
CM- Derm -9- part two Skin papules
| Question | Answer |
|---|---|
| benign neoplasm of keratinocytes of unknown pathogenesis and is most common in geriatric population | seborrheic keratoses |
| a warty, brown stuck on appearing papule on any cutaneous surface except palms and soles | seborrheic keratoses |
| What is the treatment for seborrheic keratoses | optional; destruction or surgical removal no reimbursable under medicare guidelines so let patient know that |
| benign accumulation of nevus cells that develops during puberty and evolves over lifetime | Acquired melanocytic Nevi (moles, nevocellular nevi) |
| A cell of pigmented cutaneous whose abscence of dendrites differentiates it from a melanocyte | nevus cell |
| What type of acquired melanocytic nevi are there | junctional, compound, intradermal, |
| what is the treatment for acquired melanocytic nevi | optional; excision |
| accumulation of nevus cells in skin present from birth typed small, medium or large | congenital nevi |
| what is the treatment for congenital nevi | more necessary in larger lesions, serial excisions vs laser removal |
| what can occur with congenital nevi | they can have hair growth that is large and out of place that can hide cancer development |
| what are large congenital nevi on the neck, head or posterior midline associated with | generally associated with underlying malformations usually asymptomatic but can be associated with seizures, hydrocephalus, and neurological defects |
| how is the risk of developing melanoma associated with congenital nevus | the risk of developing melanoma is proportional to the size of the congenital nevus also large nevi can hide the developing melanoma |
| benign increase of melanin in the basal layer of the epidermis present by age 3 after uv exposure | Freckles (ephilides) |
| How do freckles relate to skin cancer | they are a marker for susceptibility to skin cancer |
| what are the optional treatments for freckles | bleaching creams, chemical peels, laser removal |
| flat sharply demarcated evenly pigmented spots that are usually oval where the long axis of the oval is situated along a cutaneous nerve tract | cafe au lait spots |
| What do cafe au lait spots look like and when do they present | light to medium brown spots that usually present at birth or a little later. |
| What causes cafe au lait spots | increase in melanin content with the presence of giant melanasomes |
| specific type of leumoderma characterized by depigmentation of the epidermis | vitiligo |
| It is an acquired progressive disorder in which some or all of the melanocytes in the interfollicular epidermis and occasionlay in the hair follicles are selectively destroyed | vitiligo |
| What is the rate of vitilgo | 1-2% about 30% of cases are with familial clustering |
| What are the clinical featurs of vitiligo this is a long paragraph just read it and make sure you understand it | At first, only a few, small, and sharply circumscribed foci are present w/ hyperpigmented borders. Lesions increase in number and become confluent, taking on bizarre shapes. |
| How can vitiligo present on the body IE how much can it cover | can be localized or generalized |
| where are the most common sites for vitiligo | face, neck and scalp |
| benign increase in melanin in basal layer of epidermis usually in patches on cheeks, chin and forehead of young women | melasma |
| what is the treatment for melasma | change or stop causal medication, bleaching creams, chemical peel, lase removal, SUNSCREEN |
| Classified as simple; benign increase in melanocytes in the basal layer of the epidermis or Solar; increased melanin production | lentigines Singular or Solar |
| What is the cause of lentigines | UVA |
| What is the treatment for Lentigines | optional; bleaching creams, chemical peel, laser removal |
| apart from the epidermis what other body part can be affected by generalized vitiligo | mucus membranes |
| Apart from the face neck and scalp where does vitiligo often occur | around body orifices such as lips, genitals, gingiva, areolas, and nipples |
| Another presentation of vitiligo where the hair may depigment as well | vitiliginous macule |
| how does vitiligo of the scalp generally appear | as a localized patch of white or gray hair but total depigmentation fo the scalp may occur |
