What management step is crucial for assessing cutaneous horns?
Press to flip
Excision of cutaneous horns is crucial to assess the base lesion and rule out potential squamous cell carcinoma (SCC).
What is the common presentation and management method for sebaceous hyperplasia?
Sebaceous hyperplasia presents as yellowish papules on the face, commonly managed via electrodesiccation, curettage, or shave excision if desired.
What is a dermatofibroma and where are they commonly located?
A dermatofibroma is a reactive fibrous tissue growth typically found on extremities, often in areas affected by trauma like shaving.
When should you suspect neurofibromatosis in a patient with neurofibromas?
When there are multiple neurofibromas or associated syndromes present, referral to a specialist for potential neurofibromatosis should be considered.
How is dermatosis papulosa nigra typically managed, and what is a potential complication of treatment?
Dermatosis papulosa nigra typically requires no treatment unless for cosmetic reasons, with a risk of hypopigmentation from treatments.
Where are syringomas most commonly found and what is their typical management?
Syringomas are commonly found around the eyes and generally require no treatment except for cosmetic reasons.
Differentiate between hypertrophic scars and keloids in terms of tissue overgrowth location.
Hypertrophic scars remain within the borders of the original injury, while keloids extend beyond the initial trauma area.
What is the characteristic appearance and common locations of seborrheic keratosis (SK)?
Seborrheic keratosis appears as a stuck-on, greasy lesion predominantly on sun-exposed areas like the face, back, and chest.
What are cherry angiomas, and how might they be managed if symptomatic?
Cherry angiomas are small, red papules that might be managed by shave excision if they are symptomatic.
What sign may indicate internal malignancy when multiple seborrheic keratoses (SK) appear suddenly?
The Lesser-Trelat Sign may indicate internal malignancy when multiple SKs appear suddenly.
What are the key characteristics of lipomas and when should they be excised?
Lipomas are soft, mobile, benign adipose tissue tumors that should be excised if they are symptomatic or large.
Describe the typical presentation and common sites for stucco keratosis.
Stucco keratoses appear as white lesions predominantly on the ankles and dorsal feet and are not related to sun exposure.
Describe the typical presentation and management for keratoacanthoma.
Keratoacanthoma presents as a solitary, dome-shaped lesion with a central keratin core on sun-exposed areas and requires excision and biopsy to rule out squamous cell carcinoma (SCC).
What are the common presentation and typical management methods for skin tags (acrochordon)?
Skin tags are pedunculated soft lesions commonly found in areas of friction and can be removed using scissors or silver nitrate.
What is the typical presentation and management for pyogenic granulomas?
Pyogenic granulomas present as bright red, shiny lesions that bleed easily and are managed by curettage and electrodesiccation.
Describe the presentation and treatment options for telangiectasia.
Telangiectasia presents as red linear streaks or clusters, often treated with electrodesiccation or laser treatment.
