Some Drills On Station 5 (Part 5)



Common and readily available case for PACES. Look at this patient's extremities and proceed.

What are your findings? What are the possible differential diagnoses?

  2. There is vasculitic rash over the extremities.

    I would like to complete my Ex by checking her
    1)BP
    2)Dipstick the urine for hematuria and proteinuria (SLE, HSP, IE)
    3)Funduscope to look for haemorrhage/ cytoid body/ Roth spot
    4)Complete physical Ex for other systems involvement

    Diff
    1)CTD- SLE!!!, systemic sclerosis
    2)RA
    3)HSP ( if purpura over extensors of the LL)
    4)Drug reaction
    5)IE ........

  3. anyone think of osler-weber-rendu disease??? (Hereditary Haemorrhagic Telangectasia)

    I suppose there could be a family history of nosebleeds, haemoptysis or GI haemorrhage. Check her tongue for telangectasia!

  5. I saw a vasculitic rash on legs up to knees in an abdo exam in a patient with ?hepatosplenomegally

    How does this tie in?? is it sautoimmune disease or haematological

  7. the lesions over the palmar aspect of the hand and plantar aspect of the feet appears targetoid with a red centre surrounded by a pale circular area which in turn is surrounded by a circular red area

    i would proceed to examine the eyes,buccal mucosa and genitalia for involvement

    my dx is erythema multiforme and the differentials are:
    1) vasculitic rashes
    2) drug eruptions

  8. ok sorry pals, late reply. Have been busy with the PACES course.

    This lady in fact has MCTD with +ve anti-RNP. She also shows cutaneous stigmata of scleroderma upon palpation.

    Panhypopit is right on the right track for the differentials.

    Nope, it's not syphilitic rash for sure. And HHT won't have this confluent form of erythematous patches. Plus, it's the wrong place to look for HHT cutaneous signs!

    I'll see some of you all in the upcoming PACES course!! Surprises are in store for the participants:)
