    Correct

    • A 2 year old child was brought to casualty with recurrent episodes of eczematoid rash over the cheeks and flexural regions of his body. Which one of the following statement best suit this condition?

      Your Answer: Hydrocortisone 1% ointment should be applied sparingly to areas of active eczema

      Explanation:

      Atopic dermatitis is an allergic condition which is more apparent in those children who have a positive family history in their 1st or 2nd degree relatives. In some cases, there might be a positive history of bronchial asthma. The best treatment option in this case would be topical application of 1% hydrocortisone ointment to the affected areas of the child. We cannot prescribe a strong ointment to the face because it may lead to skin atrophy, telangiectasia and other steroid related topical complications.

    • A 37-year old female nurse presents with severe generalized itching, claiming that she had previously applied cream to the body of a patient with similar symptoms. What is the mechanism that produces her itch?

      Your Answer:

      Correct Answer: Allergic reaction

      Explanation:

      Contact dermatitis is a red, itchy rash caused by direct contact with a substance or an allergic reaction to it. The entry of allergen into the epidermis or dermis causes a localized allergic reaction. Local mast-cell activation in the skin leads immediately to a local increase in vascular permeability, which causes extravasation of fluid and swelling. Histamine released by mast cells activated by allergen in the skin causes large, itchy, red swellings of the skin.

The itching can be prickling or burning and is usually worse in the evening or night time. Triggering of urticaria by infections has been discussed for many years but the exact role and pathogenesis of mast cell activation by infectious processes is unclear.

    • A 38-year-old woman has a melanocytic naevi on her left forearm. Which of the following features do not suggest malignant change?

      Your Answer:

      Correct Answer: Decrease in size

      Explanation:

      Melanocytic nevi are benign neoplasms or hamartomas composed of melanocytes. Melanocytes are derived from the neural crest and migrate during embryogenesis to selected ectodermal sites (primarily the skin and the CNS), but also to the eyes and the ears.
      They tend to appear during early childhood and during the first 30 years of life. They may change slowly, becoming raised, changing color or gradually fading.. Pregnancy can increase the number of naevi as well as the degree of hyperpigmentation.
      They may become malignant and this should be suspected if the naevus increases in size, develops an irregular surface or becomes darker, itches or bleeds.

This is usually observed in the face, hands, forearms, and lower legs. It heals slowly and with scarring. Though blisters are the most common skin manifestations of PCT, other skin manifestations like hyperpigmentation (as if they are getting a tan) and hypertrichosis (mainly on top of the cheeks) also occur. Risk factors for the development of PCT include alcohol and sun.

The greatest risk factor is high total exposure to ultraviolet radiation from the Sun. Other risks include prior scars, chronic wounds, actinic keratosis, lighter skin, Bowen’s disease, arsenic exposure, radiation therapy, poor immune system function, previous basal cell carcinoma, and HPV infection. While prognosis is usually good, if distant spread occurs five-year survival is ,34%

    • Which of the following is FALSE with regards to vitiligo?

      Your Answer:

      Correct Answer: A positive family history is not a risk factor

      Explanation:

      The cause of Vitiligo is typically unknown. It is believed to be due to genetic susceptibility that is triggered by an environmental factor such that an autoimmune disease occurs. This results in the destruction of skin pigment cells. Risk factors include a family history of the condition or other autoimmune diseases, such as hyperthyroidism, alopecia areata, and pernicious anaemia. Vitiligo is classified into two main types: segmental and non-segmental. Most cases are non-segmental meaning they affect both sides and typically get worse with time. The prevalence of vitiligo is 0.5-1% of populations worldwide. Typical sites include backs of hands, wrists, knees, neck and around body orifices. The Koebner phenomenon refers to skin lesions appearing on lines of trauma. This occurs in vitiligo secondary to scratching.

    Incorrect

    • How would you advise your patient to apply an emollient and a steroid cream, in order to treat her eczema?

      Your Answer:

      Correct Answer: First use emollient then steroids.

      Explanation:

      If steroid is applied first, applying an emollient after could spread it from where it had been applied. If steroid is applied immediately after the emollient then it cannot be absorbed, this is why there should be a time interval of around thirty minutes between these two treatments in order for them to be effective.

      Your Answer:

    Incorrect

    • Which is NOT a poor prognostic factor for patients with malignant melanoma?

      Your Answer:

      Correct Answer: Diameter of melanoma > 6 mm

      Explanation:

      Features that affect prognosis are tumour thickness in millimetres (Breslow’s depth – the deeper the Breslow thickness the poorer the prognosis.), depth related to skin structures (Clark level – the level of invasion through the dermis), type of melanoma, presence of ulceration, presence of lymphatic/perineural invasion, presence of tumour-infiltrating lymphocytes (if present, prognosis is better), location of lesion, presence of satellite lesions, and presence of regional or distant metastasis. Malignant melanoma tends to grow radially before entering a vertical growth phase. The diameter it reaches has not been found to be a prognostic factor.

  • Question 36 - Which one of these features is typical of dermatomyositis? ...

    Incorrect

    • Which one of these features is typical of dermatomyositis?

      Your Answer:

      Correct Answer: Gottron's papules over knuckles of fingers

      Explanation:

      Dermatomyositis is a long-term inflammatory disorder which affects muscles. Its symptoms are generally a skin rash and worsening muscle weakness in the proximal muscles (for example, the shoulders and thighs) over time. These may occur suddenly or develop over months. Other symptoms may include weight loss, fever, lung inflammation, or light sensitivity. Complications may include calcium deposits in muscles or skin.
      The skin rash may manifest as aheliotrope (a purplish color) or lilac, but may also be red. It can occur around the eyes along with swelling, as well as the upper chest or back ( shawl sign) or V-sign above the breasts and may also occur on the face, upper arms, thighs, or hands. Another form the rash takes is called Gottron’s sign which are red or violet, sometimes scaly, slightly raised papules that erupt on any of the finger joints (the metacarpophalangeal joints or the interphalangeal joints)

    Incorrect

    • An 18 year old boy from Middle East presented with a 1 month history of a yellowish, crusted plaque over his scalp, along with some scarring alopecia. What will the likely diagnosis be?

      Your Answer:

      Correct Answer: Favus

      Explanation:

      Favus is a fungal infection of the scalp, resulting in the formation of a yellowish crusted plaque over the scalp and leads to scar formation with alopecia. Tinea capitus is a fungal infection of the scalp resulting in scaling and non scarring hair loss. Folliculitis presents with multiple perifollicular papules which can be caused by both bacteria and fungi. Cradle cap usually affects infants where the whole scalp is involved. It can lead to hair loss and responds to topical antifungals and keratolytics.

    Incorrect

    • Which features may suggest malignant changes in a melanocytic naevi?

      Your Answer:

      Correct Answer: Decrease in size

      Explanation:

      Melanocytic naevi are skin tumours produced by melanocytes. They usually present in childhood but increase during puberty. The mnemonic A-B-C-D, is used by institutions to assess for suspicion of malignancy. The letters stand for asymmetry, border, colour, and diameter. If a mole starts changing in size, colour, shape or, especially, if the border of a mole develops ragged edges or becomes larger than a pencil eraser, it would be an appropriate time to consult with a physician. Other warning signs include if it begins to crust over, bleed, itch, or become inflamed.
