Clinical History A 53 year old male presented with a subcutaneous right upper medial thigh nodule. He had a history of a right knee soft tissue mass resected the previous year, with reconstructive flap and radiation. The current subcutaneous nodule was palpable. Fine needle aspiration biopsy was performed. Cytopathology Features The cytology touch preparations of the core needle biopsy show a monomorphic population of loosely cohesive small blue round/oval cells. The cells are more uniform than small cell carcinoma. The nuclear to cytoplasmic ratio is high. The nuclei are round with powdery chromatin, and inconspicuous nucleoli. Cytoplasm is scant.
