FNA Diagnosis of Cutaneous Metastasis of Renal Cell Carcinoma with Initial Presentation as Scalp Lesion - Abstract
Renal cell carcinoma initially presenting as cutaneous metastasis is uncommon. We report a case of a 73 year old female with a raised, hemorrhagic, scalp lesion and no known history of malignancy. Fine needle aspiration (FNA) of the scalp lesion showed histiocytoid cells arranged singly and in groups. Immuno histochemical work up and cyto morphological features favored a diagnosis of metastatic renal cell carcinoma. CT scan of abdomen revealed a left renal mass suspicious for renal cell carcinoma. Minimally invasive procedure like FNA is helpful in the diagnosis of cutaneous metastasis of unknown primary by avoiding more invasive methods.
