Collision tumor of primary merkel cell carcinoma and chronic lymphocytic leukemia/small lymphocytic lymphoma, diagnosed on ultrasound-guided fine-needle aspiration biopsy: a unique case report and review of literature.

abstract：:Cytological and histological findings of a rare case of a malignant phyllodes tumor (with liposarcomatous components) of the breast are presented. The atypia of the stromal cells and naked nuclei in a lesion considered benign clinically and on imaging alerted us to the possibility of a phyllodes tumor, despite the low...
