Q

Capillary Hemangioma
Complications
Management

A

Amblyopia due to refractive error or visual deprivation

If visual obstruction, refer out.
Propanolol oral is treatment of choice. Or you could do topical timolol for small lesions.
Injectable steroid

Q

Epidermoid Cysts (Epidermal inclusion cyst)

  • What is it
  • Cause
A

Superficial cyst filled with keratin
Caused when surface skin cells move deeper into the skin and multiply, forming a wall. They secrete keratin which fills the cysts. Likely due to skin trauma.

25
Sudoriferous Cyst (HIdrocystoma) - What is it - cause
Superficial cyst filled with sweat. Can occur anywhere on the skin Cause- blockage of sweat gland w retention of sweat Likely a result of trauma to the skin
26
Sudoriferous Cyst (HIdrocystoma) Demographics Laterality
No predilection | Unilateral or bilateral
27
Sudoriferous Cyst (HIdrocystoma) Symptoms Signs
Asymptotic, bump on lid Flesh colored papule or nodule (dome shaped) Translucent and transilluminates Surrounding inflammation if cystic wall ruptures within the skin.
28
``` Sudoriferous Cyst (HIdrocystoma) Management ```
None if asymptomatic, may regress | Surgical excision for removal. Must remove cystic wall.
29
Sudoriferous Cyst (HIdrocystoma) located on eyelid margin is called
Cyst of Moll
30
Multiople, tiny Sudoriferous Cyst (HIdrocystoma) are called
Syringoma. Most common on cheeks and lower eyelids.
31
Squamous papilloma (papilloma, skin tag, verruca vulgaris if viral) - What is it - Cause
Benign epidermal tumor that can develop anywhere on the skin. Typically between skin folds- neck, eyelids. Proliferation of squamous epithelial cells overlying a fibrovascular core. Variable degrees of hyperkeratosis. May be a response to viral infection (HPV)
32
Squamous papilloma (papilloma, skin tag, verruca vulgaris if viral) Demographics Laterality
If associated with HPV, young adults more commonly affected. Non viral- develops after the age of 40 Unilateral or bilateral
33
Squamous papilloma (papilloma, skin tag, verruca vulgaris if viral) Symptoms Signs
Symptoms- Asymptomatic, bump on eyelid, irritation of the bump if rubbed constantly (tender/itchy) Signs- Flesh colored or hyper pigmented papule or nodule. Dome shape bump. Pedunculated (containing a stalk) or sessile (no stalk). Rough or smooth surface. Surrounding inflammation if rubbed.
34
``` Squamous papilloma (papilloma, skin tag, verruca vulgaris if viral) Management ```
None if asymptomatic, may regress. | Surgical excision for removal. Entire lesion needs to be removed or may recur if viral.
35
Most common benign eyelid lesion
Squamous papilloma (papilloma, skin tag, verruca vulgaris if viral)
36
Seborrheic Keratosis - What is it - Cause
Benign epidermal tumor **It is not seborrheic- relating to excessive discharge of sebum from sebaceous glands Proliferation of basal epithelial cells with keratin filled invaginations.
37
Seborrheic Keratosis - Demographics - laterality
Typically develops after 40 | Unilateral or bilateral
38
Seborrheic Keratosis Symptoms Signs
Symptoms- asymptomatic bump on eyelid. Can be irritated if rubbed constantly. Signs- hyper pigmented papule or nodule (dome shape) Slightly elevated from the skin with a "stuck on" appearance. Rough or smooth. Waxy.
39
Seborrheic Keratosis | Management
None of asymptomatic May spontaneously regress Surgical excision for removal
40
Multiple Seborrheic Keratosis papules on face is called
Dermatosis pupulosa nigra | More common with dark skin
41
Oculodermal Melanocytosis (Nevus of Ota) - What is it - Cause
Hyperpigmentation of the eyelid, sclera, and urea. | Cause- proliferation of melanocytes, congenital.
42
Oculodermal Melanocytosis (Nevus of Ota) Demographics Laterality
Asian and African descent. Caucasians least likely to have, but most likely to develop melanoma. Women > men Unilateral
43
Oculodermal Melanocytosis (Nevus of Ota) Symptoms Signs
Symptoms- Asymptomatic. Grey, blue or black area on eyelid. Signs- gray, blue or black eyelid/facial hyperpigmentation. Frequently follows the distribution of CN V1 and V2. Patchy, but extensive slate grey or blue scleral hyperpigmentation Variable amounts of uveal hyperpigmentation Darker iris, increased pigment in the angle, darker fundus. May have iris mammillations.
44
``` Oculodermal Melanocytosis (Nevus of Ota) Complications ```
Secondary open angle glaucoma due to pigment blocking TM
45
``` Oculodermal Melanocytosis (Nevus of Ota) Management ```
Monitor for glaucoma -IOP, gonio, ON pics, ON OCT, GCC, VF Monitor for melanoma- SL exam, A seg photos. Symptomatic- refer out for laser therapy. May cause scarring. Hyperpigmentation may recur.
46
Oculodermal Melanocytosis (Nevus of Ota) but only the sclera and urea are involved
Ocular Melanocystosis. | Same risk for glaucoma and transformation into uveal melanoma.
47
Oculodermal Melanocytosis (Nevus of Ota) but only the sclera is involved
Scleral Melanocystosis. Typically bilateral, small patches of slate grey pigmentation. Benign Common in black and asians
48
Melanocytic Nevus (mole) - What is it - Cause
Benign epidermal/dermal tumor that can occur anywhere on the skin. Proliferation of melanocytes. Associated with UV exposure. Junctional- Melanocytes clump at epidermal/dermal junction. Compound- Melanocytes extend from epidermis to the dermis Intradermal- Melanocytes clump within dermis. Most common.
49
Melanocytic Nevus (mole) Demographics Laterality
Often appear during puberty More common in caucasians Unilateral or bilat
50
Melanocytic Nevus (mole) Symptoms Signs
Asymptomatic, bump on eyelid. Signs- uniformly pigmented macule (flat lesion), papule, or nodule (dome shape). Most commonly tan, brown or black. May be amelanotic (pink). If on the eyelid, likely on the margin.
51
``` Melanocytic Nevus (mole) Complications ```
Malignant potential | Most important sign is documented change but may increase size during puberty
52
``` Melanocytic Nevus (mole) Mangagement ```
Monitor for melanoma- SL exam, A seg pictures. | Surgical excision then biopsy
