    (2007-04-22) Sharma, Alok; Sen, Achin K; Chaturvedi, Nishith K; Yadav, Rajbala
    Myofibroblastoma of breast is an extremely rare, benign mesenchymal lesion composed ofmyofibroblasts. Less than seventy cases of this entity are reported in the literature. In spite of the widely varying morphological patterns, there are few characteristic cytological, histopathological, immunohistochemical, and ultrastructural features that permit its accurate identification among a vast group of mammary spindle cell tumours. We present the case ofa 60 year male presenting with a left breast nodule, interpreted as gynaecomastia on cytology. Histopathology however revealed characteristicfeatures of a myofibroblastoma, confirmed by immunohistochemistry.

    (2006-07-28) Talwar, Nikhil; Dargan, Puneet; Arora, Mohinder Pal; Sharma, Alok; Sen, Achin K
    Squamous cell carcinoma of the renal pelvis is a rare tumor, which is usually associated with nephrolithiasis. It is rarely associated with pyonephrosis. We report the case of a 69-year-old man who presented with features of pyonephrosis and underwent nephrectomy. The postoperative histological evaluation revealed an unsuspected squamous cell carcinoma of renal pelvis with a concomitant pyonephrosis. The rarity of this tumor in the absence of renal calculi and its association with pyonephrosis is highlighted.
