Abstract:
We report the fine-needle aspiration (FNA) cytology findings of Subcutaneous Panniculitis-like T-cell Lymphoma (SCPTCL) in a 66-year-old woman who presented with a four month history of asymptomatic subcutaneous nodules on her right chest wall and back. An excisional biopsy of the right chest nodules was performed, and the diagnosis of SCPTCL was rendered. On a follow-up visit, several skin lesions were noted throughout her body. A fine-needle aspiration (FNA) of the right inguinal region was performed. The FNA yielded cellular smears, composed mainly of sheets of epithelioid histiocytes and scattered multinucleated cells. However, no distinct granulomas were noted. The background of the cytological smears showed scattered atypical lymphoid cells, some of which displayed nuclear membrane irregularities. To the best of our knowledge, the cytological features on FNA material of SCPTCL have not been described.
