Vertigo + vomiting + tinnitus + sensorineural deafness
Meredith, age 60, has noticed that the colour of her left eye is changing. She thinks the brown area has been enlarging over the past few months.
Iris melanoma. It could be a benign naevus or a melanoma, but if it is growing then melanoma should be suspected.
Fatiguable weakness of eyelids / eye movement + limbs + bulbar muscles of speech and swallowing
Joe, age 72, has noticed a skin lesion on his forehead. He thought it started a few weeks ago as a mozzie bite, but it hasn't healed and seems to be getting slowly bigger. It is not sore or itchy.

Foetal alcohol syndrome
Maria, age 42, complains that her right eye is bulging and she has double vision. This has gradually been worsening over the past couple of weeks. She is otherwise well and hasn't noticed any fevers or any other symptoms.
Orbital tumour. An orbital tumour is the most important diagnosis to consider and imaging is very important. There are other causes of a unilateral proptosis, ie cellulitis, Graves disease or other autoimmune disease, but in the absence of any other symptoms to suggest this a tumour must be high on the list of differentials.
Painful / itchy bite + agitation + hydrophobia (pain with drinking)
Betty, age 76, has noticed a gradual decline in her vision. She complains that sometimes straight lines appear wavy and there seems to be a dark patch in the middle of her vision. She has stopped driving at night because she was finding this particularly difficult. Visual acuity is 6/9 left eye, 6/12 right eye.
Age-related macular degeneration. Elderly patient, gradual onset, mildly reduced visual acuity, visual distortions, central visual field defect (ie on Amsler grid), retinal drusen on fundoscopy. There is a risk of progression to wet macular degeneration.
Mid to low back pain / discomfort + inability to touch toes + kyphosis
