In early cases multiple myeloma presents with:
**Core Concept**
Multiple myeloma is a type of bone marrow cancer characterized by the proliferation of malignant plasma cells, leading to bone destruction, renal impairment, and immune system dysfunction. Early cases of multiple myeloma often present with a combination of symptoms related to bone destruction and immune system compromise.
**Why the Correct Answer is Right**
The correct presentation of early multiple myeloma involves a combination of bone pain, anemia, and renal impairment. Bone pain is due to the lytic lesions caused by the proliferation of malignant plasma cells, leading to bone destruction. Anemia is a result of the suppression of normal plasma cell function, leading to decreased erythropoietin production. Renal impairment is caused by the hypercalcemia and light chain deposition in the kidneys.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incomplete and does not provide a clear symptom or presentation of multiple myeloma.
* **Option B:** This option is incorrect as it does not accurately describe the early presentation of multiple myeloma.
* **Option C:** This option is incorrect as it does not include all the key symptoms of early multiple myeloma, particularly renal impairment.
**Clinical Pearl / High-Yield Fact**
Early cases of multiple myeloma can be challenging to diagnose due to non-specific symptoms. However, the presence of bone pain, anemia, and renal impairment should raise suspicion for this condition. It is essential to consider multiple myeloma in the differential diagnosis of patients presenting with these symptoms.
**Correct Answer: C. Bone pain, anemia, and renal impairment.**
