27
Q

Malignant Skin Tumors, BCC and SCC, Surgical - Electrosurgery: After this, electrodesiccation is done why

A

to achieve homeostasis and destroy any viable malignant cells at the base of the wound or its edges. Useful for lesions smaller than 1-2 cm.

28
Q

Malignant Skin Tumors, BCC and SCC, Surgical - Electrosurgery: This method takes advantage of what?

A

That utmor is softer than surrounding skin and can be outlined by a curette, which feels for the extent of the tumor. Usually repeated twice, and healing within 1 month

29
Q

Malignant Skin Tumors, BCC and SCC, Surgical - Cryosurgery: How does this work

A

DEstroys tumor by deep-freezing the tissue. Needle inserted into skin and liquid nitrogen directed to center of tumor.

30
Q

Malignant Skin Tumors, BCC and SCC, Surgical - Cryosurgery: What happens to tumor here?

A

Tissue is frozen, allowed to that, and then refrozen. Site thaws naturally and then becomes gelatinous and heals spontaneously.

31
Q

Malignant Skin Tumors, BCC and SCC, Non-Surgical Alternatives: What are two options that can be done?

A

Local radiation therap or PDT

32
Q

Malignant Skin Tumors, BCC and SCC, Non-Surgical Alternatives: What does PDT involve?

A

Application of 5-aminolevulinic acid to the lesion, which is followed by photoactivation with directed blue light for approximately 1 hour. Destroys neoplastic cells.

33
Q

Malignant Skin Tumors, BCC and SCC, Non-Surgical Alternatives: Problem with PDT?

A

Skin may become red and blistered after any of these therapies

34
Q

Malignant Skin Tumors, BCC and SCC, Nurse Mx: Patient is advised to watch for what?

A

Excessive bleeding and tight dressings that compromise circulation.

35
Q

Malignant Skin Tumors, BCC and SCC, Nurse Mx: What is done after sutures are removed?

A

Emollient cream may be used to prevent dryness.

36
Q

Malignant Skin Tumors, BCC and SCC, Nurse Mx: Follow-up exams should occur how often?

A

At regular intervals, usually every 3 months for a year. Should include palpation of adjacent lymph nodes.

37
Q

Malignant Skin Tumors, Melanoma: Wht is this?

A

Nancerous neoplasm characterized by neoplastic melanocytes present in the epidermis and the dermis.

38
Q

Malignant Skin Tumors, Melanoma: How deadly is this?

A

It is the most lethal

39
Q

Malignant Skin Tumors, Melanoma, CMs: This may manifest as what>?

A

Change in the nevus or a new growth on the skin arising from cutaneous epidermal melanocytes.

40
Q

Malignant Skin Tumors, Melanoma, CMs: Malignant melanoma looks how

A

dark, red, or blue colored, or a mix of any of these and irregular in shape.

41
Q

Malignant Skin Tumors, Melanoma, CMs: What may this be associated with?

A

Itching, rapid growth, ulceration, and bleeding. Found mmore commonly in lower extremities.

42
Q

Malignant Skin Tumors, Melanoma, CMs: Can occur in what forms?

A

Superficial Spreading of Melanoma (SSM)

Lentigo Maligna Melanoma (LMM)

Nodular Melanoma (NM)

Acral LEntiginous Melanoma (ALM)

43
Q

Malignant Skin Tumors, Melanoma, CMs: In rare instances, melanomas may develop where?

A

In the uveal tract of the eye or from the mucosal lining of the GI or GU tract

44
Q

Malignant Skin Tumors, Melanoma, CMs: Spread in what two growth phases?

A

Radial and vertical

45
Q

Malignant Skin Tumors, Melanoma, CMs: What occurs during the first growht phase ,the radial phase?

A

Cutaneous melanomas tend to spread radially within the layer of the epidermis. Is most amenable to treatment

46
Q

Malignant Skin Tumors, Melanoma, CMs: What occurs during the second growth phase, the vertical phase?

A

Characterized by vertical tumor growth into the dermal layer and eventual metastasis.

47
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: What confirms the diagnosis of melanoma?

A

Biopsy results

48
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: Excisional biopsy provides information on what

A

type, level of invasion, adn thickness of lesion. Includes a 1-2 cm margin of normal tissue.

49
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: When should incisional biopsy be performed?

A

When suspicious lesion is too large to be removed safely without extensive scarring.

50
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: What should a thorough history and physicl exam include?

A

A meticulous skin exam and palpation of regional lymph nodes that drain the lesional area.

51
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: What is usually performed after diagnosis of melanoma is confirmed?

A

Elevated in presence of metastatic disease.

53
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: Depending on results, what diagnostic tests can be performed?

A

MRI of brain, CT scans of chest, abdomen, or pelvivs, and PET scan of the lymphatics.

54
Q

Malignant Skin Tumors, Melanoma, Assess/Diagnostic: Staging of tumors follows what system?

55
Q

Malignant Skin Tumors, Melanoma, Medical Mx: What is the treatment of choice for small, superficial lesions?

A

Surgical excision

56
Q

Malignant Skin Tumors, Melanoma, Medical Mx: Deeper lesiosn require what?

A

Wide, local excision where skin grafting may be necessary

57
Q

Malignant Skin Tumors, Melanoma, Medical Mx: Sentinel lymph node biopsy performed why

A

to examine the nodes nearest the tumor and to spare the patient the long-term sequelae of extensive removal of lymph nodes.

58
Q

Malignant Skin Tumors, Melanoma, Medical Mx: What genetic mutation do most people have which helps in guiidng targeted therapy?

59
Q

Malignant Skin Tumors, Melanoma, Medical Mx: Patients with Stage II/III considered at risk for relapse are typically prescribed what?

A

High-dose interferon alpha-2 IV for 4 weeks, followed by subcutaneous dosing for an additional 48 weeks. Helps with decreased rates of relapse.
