I. CASE STUDY HISTORY AND ILLNESS PRESENTATION

Chief Complaint: “One of the moles on my face is changing.”

History of Present Illness:

Mr. C., a 62 year old farmer, comes to the clinic to have an exam about a change in the mole on his face. He just noticed the change 2 weeks ago. He says the mole doesn’t itch, but it has grown larger daily and is darkening. He has not noticed any discharge from the site. He denies being bitten by any insects. Although he works outdoors daily, he does not use sunscreen.

Mr. C has smoked one cigar daily for the past 35 years. On average, he drinks three beers daily and has done so for the past 40 years. He had a broken tibia repaired 2 years ago.

His father died of complications of melanoma. His mother died of lung cancer.

Actual findings on physical examination:

• Alert older man, resting comfortably on the exam table.

• BP 110/60 HR=86 and regular Respirations=24 Temp=98.6 F

• 1cm black, irregularly shaped, slightly elevated lesion on the right forehead.

• Multiple nevi scattered on the back, abdomen, arms and legs.

• Numerous capillary hemangiomas on the abdomen.

• HEAD: normocephalic, atraumatic.

• Eyes: Pupil’s equal, round, and reactive to light and accommodation, constrict from 6mm to 3mm. Disc margins sharp, fundi without hemorrhages or exudates.

• External ear canals patent, tympanic membranes with cone of light

• Oral mucosa pink, dentition in good repair, pharynx without exudates

• NECK: Supple without thyromegaly no lymphadenopathy

• THORAX/LUNGS: Thorax symmetric, lungs resonant, breath sounds vesicular.

III. IDENTIFY PHYSICAL FINDINGS TO HELP DETERMINE DIAGNOSIS

|System or | |

|Area Examined |What are we looking for to determine the diagnosis? |

|General Survey |Patient’s report of patterns of sun exposure. Total cumulative sun exposure strongly associated with basal cell and squamous cell carcinoma. Intermittent |

| |sun exposure associated with melanomas. |

| |History of blistering sun burns. |

| |Mental status changes, weakness, cachexia may indicate metastatic process in the brain. |

|Vital signs |Within normal parameters serves as a measure of general physiological wellness |

| |Exceeding normal parameters indicates the impact of disease processes. |

|Skin |Characteristics of mole in question (ABCDE) |

| |Other lesions – atypical mole/dysplastic nevus – associated with increased risk for melanoma. |

| |Texture of skin – leathery skin is indicative of total cumulative sun exposure. |

| |Erythema, inflammation and/or tenderness surrounding mole in question – may indicate dysplastic nevus transforming to melanoma |

| |Complexion / skin phototype providing an idea of possible severity of sunburn (extent of intermittent sun damage) |

|System or | |

|Area Examined |What are we looking for to determine the diagnosis? |

|Head, Neck and Lymphatic system |Color of hair and eyes to determine skin phototype (predisposition for suntan and sunburn which will increase risk for skin cancer). |

| |Oral cavity for lesions which could indicate oral malignancies from smoking. |

| |Lymphadenopathy in head or neck area could be indicative of malignant metastasis through the lymphatic system (sentinel lymph nodes). |

| |Palpable supraclavicular lymph nodes are tell-tale sign of malignancy (Seidel, p.217) |

| |Lymph nodes fixed to surrounding tissues, harder than expected & with asymmetrical involvement are causes for concern (Seidel, p.223, 225) |

| |Older patient with localized, persistent lymphadenopathy without evidence of infection or inflammation possible indication of malignancy (Seidel, p. 229) |

|Thorax & Lungs |Abnormal breath sounds, difficulty breathing, poor oxygenation and signs of respiratory insufficiency may be indicative of lung involvement – especially |

| |considering patient’s family history of cancer. |

I. LIST 3 DIFFERENTIAL DIAGNOSES WITH RATIONALE

Based on the information provided, the following differential diagnoses are considered:

a. Melanoma

• A: Symmetry/asymmetry – inadequate information given – clinician must assess

• B: Irregularly shaped lesion

• C: Color is darkening – now almost black (not stated if color changed uniformly or if variegation occurred).

• D: size >0.5cm,

• E: Patient reported evolution/elevation - mole has grown bigger and is slightly elevated

• Area of concern is located in area often noted to be vulnerable to effects of the sun.

• Patient has a family history of melanoma

• Several risk factors exist such as lack of use of sunscreen and an occupation where sun exposure occurs.

• Diagnosis based on biopsy findings from the lesion.

• However, melanoma is more often found on skin areas where intermittent sun exposure occurs (e.g. back in men and lower legs in women) (Porth & Matfin, p. 1591)

b. Seborrheic Keratosis

• Most common of the benign epithelial tumors

• Hereditary lesions – do not appear until age 30 and continue to occur over a lifetime,

• Varying from few scattered lesions to sometimes hundreds in elderly patients

• Range from small, barely elevated papules to plaques with warty surface and “stuck-on” appearance,

• Can mimic the look of melanoma

• Occurs frequently in the age group of the patient.

• Lesions may be skin-colored, tan, black, verrucous papules/plaques – black pigmented lesions more often found in black Africans, African Americans, deeply pigmented south-east Asians.

• Large pigmented lesions easily mistaken for pigmented basal cell carcinoma or malignant melanoma

• Verruca vulgaris is similar in appearance but thrombosed capillaries are present

c. Pigmented basal cell carcinoma (Fitzpatrick p. 287-293)

• Most common cancer in humans (Fitzpatrick p. 287) – most common skin cancer in light skinned people (Porth & Matfin, p.1592)

• Caused by UVB spectrum rays – especially associated with prolonged exposure (total cumulative sun exposure) and heavy sun exposure in youth (sunburns before age 20)

• Clinically different types (nodular, ulcerating, pigmented, sclerosing and superficial)

• Locally invasive, aggressive and destructive but slow growing.

• Very limited (almost none at all) tendency to metastasize

• Pigmented clinical type: brown to blue or black

• Smooth, glistening surface

• Hard or firm

• May be indistinguishable from superficial spreading or nodular melanoma but is usually harder.

• Stippled (variegated) pigmentation may be seen

• Usually isolated lesion (> 90% occurring in face) and appears mostly in “danger sites”

• medial and lateral canthi, nasolabial fold, behind the ears, sometimes on trunk

• Has capacity to develop hair follicles

d. Dysplastic nevus

• Larger than other nevi (often > 5mm in diameter)

• Often appear as a flat, slightly raised plaque with a pebbly surface, or a target-like lesion with a darker, raised center and irregular border.

• Vary in color from brown and red to flesh tones.

• One person may have hundreds of these lesions – occurring both in sun exposed and covered areas of the body.

• Documented in multiple members of families prone to develop malignant melanoma – possibility of malignant transformation – especially when changes occur (size, thickness, color, itching and bleeding) (Porth & Matfin, p. 1590).
