    Transcript

    00:02 Another type of non-Hodgkin’s lymphoma brings us to Burkitt.

    00:06 The Burkitt lymphoma, here, you have endemic or non-endemic type.

    00:11 The endemic type would be of the African, non-endemic type is then called the sporadic.

    00:17 And associated with latent EBV more so with endemic.

    00:22 Here, the translocation will be 8;14 and the gene here will be C-myc.

    00:28 The 14 again to you should mean immunoglobulin heavy chain.

    00:33 These translocations lead to upregulation to C-myc in which there’s going to be increased promotion of growth and division.

    00:42 Now, with Burkitt lymphoma, the endemic type, this African boy that you probably have seen the picture of and I’ll show you further, is almost always involving the mandible.

    00:52 And if it’s a sporadic type, you’re thinking about either the abdominal or the pelvic region.

    00:58 That will be the non-endemic type.

    01:00 Histologic picture, once again, remember this is a non-Hodgkin’s lymphoma affecting the lymph node and of B-cell origin.

    01:10 Diffuse infiltrate of medium-sized cells.

    01:14 You might have heard of the term starry sky appearance.

    01:17 A large number of mitotic and apoptotic cells and scattered benign macrophages that you’re seeing here then represents or create a picture of what’s called starry sky.

    01:28 By that we mean, that if you take a look at the overall picture here, appears as being dark blue.

    01:35 In the middle, do you see the twinkling stars? Yeah.

    01:40 That would be your scattered macrophages.

    01:49 Clinically, Burkitt lymphoma, all forms occur at extranodal sites.

    01:55 Remember, non-Hodgkin’s lymphoma can commonly be involved with extranodal.

    02:01 The different types and their demographics, endemic African, please observe the jaw and the mandible in this child who’s suffering from Burkitt lymphoma.

    02:14 Endemic.

    02:16 Non-endemic, known as sporadic.

    02:20 Pelvic abdominal region and you can have non-Hodgkin’s lymphoma with HIV association.

    02:28 Here, very aggressive.

    02:31 Remember with HIV status, it is important that you pay attention to your non-Hodgkin’s lymphoma including your diffuse large B-cell lymphoma.

    02:42 Endemic and sporadic type, most common, frequently seen in children and young adults.

    02:47 HIV can occur at any age as you can imagine and generally very aggressive, responds well with short-term and high-dose chemotherapy with management.
