    2015 12 AZ Sentinel Lymph node sampling

    Multiple choice question


    According to the most comprehensive study summarizing follow-up data on sentinel lymph node sampling in melanoma, which statement is not true?


    2015 11 AZ melanoma FISH #13

    Multiple choice question

    The main sourse of false-positive results in melanoma FISH is tetraploidy. In tetraploid cells increased number of intact chromosomes leads to increased signals with all FISH probes. In contrast, selective amplifications or deletions of genetic material is the most characteristic for melanoma. Importantly, not all the signals can be visible in a nucleus from a nevus cells as some FISH probe binding sites may not be in the plane of section. Keeping this in mind answer the question which FISH result from the options bellow is most compatible with malignant melanoma?

    Ana question #12

    Multiple choice question

    Fluorescent in situ hybridization techniques have been used as an adjunct tool in the diagnosis of melanoma. It can be done either on formalin fixed, paraffin-embedded sections or on fresh-frozen tissue. A 4-probe multicolor melanoma FISH is the most commonly used and targets chromosomes 6 and 11. Each fluorescently labeled fragment of DNA that hybridizes to a tumor cell nucleus will appear as a distinct fluorescent dot. Each dot identifies a single copy of the chromosomal locus with a homologous DNA. Knowing that melanomas are characterized by chromosomal copy number aberrations, what is the best interpretation for the figure below?

    Aqua: Cen 6

    Yellow: MYB

    2015 21 Zn deficiency

    Multiple choice question

    Acrodermatitis enteropathica can be an autosomal recessive inherited disorder or acquired, especially in patients with eating disorders or chronic malabsorption conditions. The clinical syndrome is characterizd by a triad of acral dermatitis, alopecia, and diarrhea. What are the most common features found in the biopsy?


    2015 22 Macular arteritis

    Multiple choice question

    Macular arteritis is a recently described clinicopathological entity. It is characterized clinically by asymptomatic erythematous and hyperpigmented macules and/or livido reticularis on the lower limbs. Which is true about biopsy findings in macular arteritis?


    2015 23 Drug eruptions

    Multiple choice question

    Drug reactions can happen at any time after commencement of the treatment with a drug. Knowing the time-course of different drug eruptions can be helpful in identifying the offending drug. Which is not true about time-course of different types of drug eruptions?

    2015 7 EMPSG question #8

    Multiple choice question

    Endocrine mucin producing carcinoma of the eyelid is a recently described lesion which is precursors to mucinous carcinoma of the eyelid. Which is not true about this tumor?

    2015 8 AZ Seb CA question #7

    Multiple choice question

    Sebaceous carcinomas of the eyelid is an aggressive tumor which is often misdiagnosed.  Key histological features for the diagnosis includes: pagetoid spread, involvement of hair follicles, infiltrative growth, nests with comedo necrosis, and epithelioid cells with vesicular nuclei and bubbly vacuolated cytoplasm. In some cases it may extremely difficult to distinguish ocular sebaceous carcinoma from basal cell carcinoma or squamous cell carcinoma.

    Which is not true about ocular sebaceous carcinoma?

    2015 24 Pseudobowenoid changes

    Multiple choice question

    Pseudobowenoid changes of the vulva is an HPV-induced lesion described on the vulva which has similar histologic changes to those seen in oral Heck’s disease (focal epithelial hyperplasia). Both conditions are induced by rare HPV variants. Histological feature characteristic for these entities include epithelial hyperplasia with broad rete ridges, koilocytes, and presence of mitosoid bodies.

    Mitosoid figures from a representative case from the vulva are shown below.

    Which types of HPV have been associated with this disease?


    2015 25 Lyme disease

    Multiple choice question

    Lyme disease is caused by a spiroquete Borrelia burgdorferi. It is transmitted by the Ixodes tick. Histologically, erythema chronicum migrans  is characterized by a non-specific lymphocytic perivascular and perineural inflammatory infiltrate, usually associated with plasma cells. What other condition can be also associated with Lyme disease?

    2015 26 Leprosy

    Multiple choice question

    Which form of leprosy is characterized by well formed perineural granulomas and absent bacilli?

    Ana question #3

    Multiple choice question

    Leprosy is caused by Mycobacterium leprae, which is an obligate intracellular gram-positive, weakly acid fast organism. The disease can present in many different forms, depending on the immune response of the patient. Which form of leprosy has the highest number of organisms found in the biopsy specimen?

    2015 27 Erythrasma

    Multiple choice question

    Erythrasma is caused by an actinobacteria of the genus Corynebacterium (C. minutissimum). Which of the folling statements about skin biopsies in erythrasma is not true?

    Ana question #1

    Multiple choice question

    Erythrasma is a bacterial infection of the skin, which occurs symmetrically in intertriginous areas, and is one of the differential diagnoses for “normal skin” histology on H&E stain. Knowing that it is caused by an actinobacteria of the genus Corynebacterium, which species causes erythrasma?

    Taube question #8

    Multiple choice question

    The PD-L1/PD-1 immune “checkpoint” may be co-opted by tumors to turn off the anti-tumor host immune response.  New anti-PD-1 or anti-PD-1 immunotherapies block this interaction, effectively “releasing the brakes” on the host immune system and allowing it to fight tumor. The expression of PD-L1 as detected by immunohistochemistry has been studied as a marker of response to anti-PD-1/PD-L1 immunotherapy. 

    Complete the following statement:

    Patients whose tumors are negative for PD-L1....

    Taube question #7

    Multiple choice question

    Which domains to the p40 and p63 antibodies recognize, respectively?

    2015 28 Vasculitis

    Multiple choice question

    The “gold standard” for the diagnosis of cutaneous vasculitis is:

    2015 29 Vasculitis

    Multiple choice question

    The slide below shows a biopsy from a purpuric lesion on the leg of a 18 y/o man who recently recovered from an upper respiratory tract infection. The biopsy showed classic features of leukocytoclastic vasculitis. However, in some cases the biopsy of leukocytoclasitc vasculitis can be false-negative because it is taken too early or two late in the cycle of lesion development. The timing of biopsy is critical for highest diagnostic yield.

    The lesion represented in this specimen was most likely biopsied within what time frame after appearance of the lesion?

    2015 5 Taube question #4

    Multiple choice question

    81 y/o woman with history of lichen sclerosus presented with raised plaque on the vulva. A biopsy was performed. It showed so called differentiated vulvar intraepithelial neoplasia (VIN).

    Which of the following is true about this entity?
