What does the patient’s initial presentation suggest to you?
This patient’s initial presentation suggests an inflammatory syndrome or a malignancy. Of course, in a patient that is this young and with those symptoms, you may be thinking more towards an inflammatory syndrome. Fortunately, some laboratory tests were done that looked at her ANA and looked at other inflammatory markers. Considering the potential downside risk of this being a malignancy, it’s really important to evaluate for both autoimmune diseases and malignancies. The FDG uptake on the PET scan SUV max suggests that this is not a high-grade malignancy, but it certainly does not rule out the possibility of it being a malignancy. The fact that the FNA was uninformative is not too surprising, but it’s absolutely the right move for this patient to then go on to have an excisional biopsy to determine: does this patient have a malignancy or should they be pursuing more systemic inflammatory disorders.
