A 54 year male with massive splenomegaly, early fatigue, malaise, low-grade fever, gout, increased susceptibility to infections, anemia, with TLC-1,25,000, and thrombocytopenia with easy bruising. The diagnosis is associated with following chromosomal translocation
**Core Concept**
The patient's symptoms suggest a hematological malignancy, specifically a type of leukemia. The chromosomal translocation is a genetic abnormality that can lead to the development of this disease.
**Why the Correct Answer is Right**
The patient's presentation is consistent with Chronic Lymphocytic Leukemia (CLL), a type of cancer that affects the immune system. CLL is characterized by the accumulation of abnormal lymphocytes in the bone marrow, spleen, and blood. The chromosomal translocation t(11;14) is a common genetic abnormality associated with CLL, involving the rearrangement of the cyclin D1 gene (CCND1) and the immunoglobulin heavy chain gene (IGH). This translocation leads to the overexpression of cyclin D1, promoting lymphocyte proliferation and survival.
**Why Each Wrong Option is Incorrect**
**Option A:** t(9;22) is associated with Chronic Myeloid Leukemia (CML), a different type of leukemia that is characterized by the BCR-ABL fusion gene. While CML can also present with splenomegaly and increased susceptibility to infections, the chromosomal translocation is different.
**Option B:** t(14;18) is associated with Follicular Lymphoma, a type of non-Hodgkin lymphoma. This translocation involves the rearrangement of the BCL2 gene and the IGH gene, leading to the overexpression of BCL2 and promoting lymphocyte survival.
**Option C:** t(8;14) is associated with Burkitt Lymphoma, a type of non-Hodgkin lymphoma. This translocation involves the rearrangement of the MYC gene and the IGH gene, leading to the overexpression of MYC and promoting lymphocyte proliferation.
**Option D:** t(15;17) is associated with Acute Promyelocytic Leukemia (APL), a type of acute myeloid leukemia. This translocation involves the rearrangement of the PML gene and the RARA gene, leading to the formation of the PML-RARA fusion protein and promoting abnormal cell differentiation.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the diagnosis of CLL often involves a combination of clinical presentation, laboratory findings, and genetic analysis. The presence of specific chromosomal translocations can help guide treatment decisions and predict patient outcomes.
**Correct Answer: C. t(11;14)**
