Benign triton tumors (BTT) are very rare lesions composed of mature skeletal muscle and neural tissue. We report a case of a 14-year-old boy who presented with asymptomatic swelling of the chin over an 18-month duration which increased gradually to involve the left side of the lower lip. Clinically, a diagnosis of neurofibroma was made. Excisional biopsy(More)
Chondroblastoma is a rare, giant cell-rich, benign neoplasm of bone. Since the past few decades fine needle aspiration cytology (FNAC) has gained momentum in preoperative diagnosis of bone lesions. At cytology, other giant cell-rich tumors and tumorlike lesions such as aneurysmal bone cyst (ABC), giant cell tumor, and chondromyxoid fibroma fall under the(More)
Primary cutaneous T-cell lymphoma is a rare lymphoproliferative disorder accounting for 2% of all lymphomas. Mycosis fungoides (MF) is a rare, albeit commonest form of primary cutaneous T cell lymphoma. MF d'emblee is an uncommon variant which is easily mistaken clinically for epithelial malignancy. Diagnosis at cytology is challenging due to low degree of(More)
A 60-year-old male, diabetic presented with a soft tissue mass over the right forearm of 15 days duration. The swelling was 5 x 3 cm and a clinical diagnosis of neurofibroma was made. Fine Needle Aspiration Cytology (FNAC) was done using standard technique. Smears showed predominantly suppurative inflammation, foreign body giant cells, granulomas and fungal(More)
This paper illustrate the design and realization of control drive electronics of Limited Angle brushless torque motor for position control of Scan mirror mechanism. The scan mirror mechanism is controlled for the intended limited mechanical angle within +/20deg. The control drive is designed for six selectable positions within +/20deg with an accuracy of(More)
