2015 20 AIDS-induced neoplasia

    Multiple choice question

    Advent of HAART (incl. cART) has resulted in improved morbidity, mortality & life expectancy of patients with AIDS.

    As a result, there is declining incidence of AIDS-defining illnesses, incl. AIDS-defining malignancies. However, deaths due to non-AIDS defining cancers are on the rise (3x ↑).

    Skin biopsy in acute exanthem of HIV infection typically shows which pattern of tissue reaction?

    2015 9 WG Osteogenic melanoma

    Multiple choice question

    Rare variants of melanoma can show areas of divergent differentiation such as schwannian, smooth muscle, skeletal muscle, cartilage, osteoid, neuroendocrine, etc.

    The term metaplastic melanoma is aplied to melanomas showing cartilaginous (chondroid melanoma) or osteoid (osteogenic melanoma).

    Which of the following is the most common site of occurence of osteogenic melanoma?



    2015 13 Immune checkpoint therapies

    Multiple choice question

    Interaction of PD1-Ligand expressed on melanoma cells with PD1 receptor on activated tumor-specifice T cell provides inhibitory signal which supresses T cell activation. This is a critical mechanism of resistance of tumors towards immune response. Blocking of this interaction by anti-PD1 drugs is called immune checkpoint blockade. It is a very promising mechanims targeted by drugs which has shown to result in long-term survival in some patients with advanced melanoma and other malignancies.  





    Which of the following statement about immune check point blockage and PD1 targeting by anti-cancer drugs  is not true?






    2015 14 Next Gene Sequencing

    Multiple choice question

    The term Next-Gen Sequencing refers to massive parallel sequencing of DNA or cDNA  This technology allows to sequence each gene many times (up to 500 times) to increase sensitivity. It can detect base pair mutations, insertions, deletions, copy number changes, translocations in one sequencing reaction. Which of the following statements regarding Next Gene Sequencing is true:

    2015 4Odontogenic keratocyst

    Multiple choice question

    The image below show biopsy of parakeratinizing odonotogenic keratocyst.

    Which of the following statements regarding this entity is not true?

    Multiple choice question

    The number of melanoma cases worldwide is believed to be increasing faster than any cancer other than non-melanoma skin cancer, with estimates suggesting a doubling of melanoma incidence every 10-20 years.   It has been estimated that in 2013 there were 76,690 new cases of cutaneous melanoma in the USA, and that 9,480 people in the USA died from cutaneous melanoma.



    These findings have led to statements that cutaneous melanoma has become epidemic in Caucasian populations in many parts of the world.  Melanoma is often cured if excised at an early/thin stage, but until very recently advanced/metastatic melanoma has had a very high fatality rate, and been considered for the most part to be incurable.   Therefore, in the past 30 years great effort has been put into lowering the death rate from cutaneous melanoma  by identifying lesions at an early, curable stage, and screening individuals for early lesions.

    Which statement about cutaneous melanoma in the USA has been true for the past 30-40 years? (choose one)

    Multiple choice question

    A biopsy is submitted from the cheek of an 82 year old man.  It contains a spindle cell proliferation that you are concerned could be desmoplastic melanoma.  Which of the following are most likely to help you identify desmoplastic melanoma? 

    2015 37

    Multiple choice question

    Muir-Torre syndrome is an autosomal dominant disorder that is due to mutation in mismatch repair genes (MSH-2, MLH-1, MSH-6, PMS-2) with resultant microsatellite instability.

    Which of the following is of greatest concern for associated Muir Torre syndrome?

    2015 38 Leishmaniasis

    Multiple choice question

    A biopsy is submitted of an ulcerated crusted nodule.  It reveals parasitized histiocytes. 

    Of the following, which is the most likely diagnosis?

    Tammie Farringer question #4

    Multiple choice question

    Excisional biopsy of a draining sinus reveals a suppurative infiltrate with pigmented grains.  Of the following, which is the most likely diagnosis?

    Tammie Farringer question #3

    Multiple choice question

    Myiasis is infestation of tissue by Diptera larvaClinical presentations include wound and furuncular myiasis.  Furuncular myiasis occurs at the bite of an insect, most commonly due to Dermatobia hominis in warm humid, low land forests of Central and South AmericaThe female glues her eggs to the abdomen of a captured insect.  This vector then bites the host.  The larvae sense the change in temperature, detach, and burrow into the subcutaneous tissue through the bite or a follicle.  The larva grows and matures over 6-8 weeks before emerging.  The larva has an undulating thick chitinous wall with 2 to 6 rows of dark pigmented setae that prevent dislodgement. 

     Myiasis is infestation of tissue by:

    2015 39 Spirometra

    Multiple choice question

    Nematodes or round worms contain a “tube within a tube” or a gut. Cestodes (flat worm/tapeworm) have a secretory tegument but no gut. The worm depicted below lacks a gut.

    It is which one of the following?

    Dr. Tammie Farringer's Question #2

    Multiple choice question

    Although the tumor necrosis factor (TNF) inhibitors are sometimes used to treat psoriasis, paradoxical psoriasiform eruptions not uncommonly result from use of these drugs in patients with inflammatory bowel disease or rheumatoid arthritis without a history of psoriasis.  It may be due to disruption of the cytokine balance by TNF blockage allowing unopposed IFN-alpha production by plasmacytoid dendritic cells.  Which of the following is most likely to cause a psoriasiform eruption?

    2015 40

    Multiple choice question

    Lyme disease is caused by the spirochete Borrelia burgdorferi.  It is transmitted to humans through the bite of infected black legged ticks (Ixodes), including Ixodes scapularis (deer tick or black legged tick) and Ixodes pacificus (western black legged tick). In contrast, Dermacentor ticks transmit Rocky Mountain Spotted Fever. Amblyomma americanum (lone star tick) transmits human ehrlichiosis and tularemia. 

    The adult female tick that typically transmits Lyme disease, is characterized by which of the following features?
