Chloroma: A Sign of Acute Myeloid Leukaemia
A chloroma, also known as granulocytic sarcoma, is a tumor composed of immature myeloid cells (granulocytes). This condition is a specific clinical manifestation strongly associated with myeloproliferative disorders.
Understanding Chloroma's Association
- Chloroma specifically indicates the presence of immature granulocytes, which are characteristic of Acute Myeloid Leukaemia (AML).
- While chloromas can occur in other myeloproliferative conditions, they are most frequently observed in patients diagnosed with AML.
- The tumor appears as a greenish mass, hence the name "chloro" (green).
Evaluating the Options
- Acute Myeloid Leukaemia (Option C): This is the correct answer. Chloroma is a recognized extramedullary (outside the bone marrow) manifestation of AML.
- Burkitt's lymphoma (Option 1): This is a type of non-Hodgkin lymphoma involving lymphoid cells, not myeloid cells.
- Acute lymphoblastic leukaemia (Option 2): This leukaemia involves lymphoid precursor cells (lymphoblasts), not myeloid cells like those found in a chloroma.
- Ewing's sarcoma (Option 4): This is a primary bone tumour and is unrelated to myeloid leukaemia or chloroma.
Therefore, chloroma is a key feature associated with Acute Myeloid Leukaemia.
