Abstract: Understanding muscle architecture of the foot may assist in the design of surgical procedures such as tendon transfer, biomechanical modeling of the foot, prosthesis design, and analysis of foot function. This paper primarily focuses on the variation of Flexor Digitorum Longus and Brevis muscles of foot. Sixty inferior extremities were dissected. While dissecting a body of adult female we observed a small muscle belly taking origin from the medial and lateral processes of the calcaneal tuberosity and get inserted in the distal phalanx of the little toe of right foot. The 4th tendon of the Flexor Digitorum Brevis muscle was absent and the respective tendon of the Flexor Digitorum Longus muscle to the little toe was atrophied in same foot. This additional muscle belly is pierced by one of branch of lateral planter nerve. The importance of such variations is to be kept in mind during radio-diagnostic procedures and surgical interventions.

Abstract: Fibrous Dysplasia of bone is an uncommon congenital skeletal disorder that is found equally in both genders and is not inherited. Fibrous Dysplasia is characterized either monostotic or polyostotic, and may occur as a component of McCune Albright Syndrome or the rare Mazabraud Syndrome. Long bones, skull bones and ribs are most commonly affected bones.1 We present a case of a 18 years old boy having pathological fracture of right shaft femur due to Fibrous Dysplasia associated with Ichthyosis Vulgaris. Clinicoradiological examination further established our diagnosis. Biopsy stated delicate trabeculae of immature bone, with no osteoblastic rimming, enmeshed within a bland fibrous stroma of dysplastic spindle shaped cells without any cellular features of malignancy.

Abstract: The light microscopic structure and the effect of superior cervical ganglionectomy on the pineal gland of Rhesus monkey was studied in 24 animals. The animals were divided into three groups. Group I normal controls, Group II after unilateral and Group III after bilateral ganglionectomy. The animals in group II were sacrificed 15 days and group III were sacrificed 21 days after the operation. Every seventh slide of serial paraffin sections were stained with H&E stain, Red Holzer's stain for glial fibers, Weigert's and Van Gieson's stain, Weil's stain for myelin sheath, Peter's protein silver stain for nerve fibers and Glee's stain for degenerating nerve fibers .

Abstract: Dermatofibroma , also known as benign fibrous histiocytoma is a soft tissue tumor that usually occur in the mid adult life and shows a slight female predominance. Giant dermatofibroma , a very rare clinical variant is characterised by its unusually large size , benign biological behaviour despite its large size and same histopathological characterstics as conventional dermatofibroma .. We report a case of a 20 years old female presenting with a rapidly enlarging large mass in right leg in calf muscle region with history of progressive enlargement for past 4 years. The mass measured 13cm in greatest dimension. The patient underwent total excision of the tumor with wide local margin and histopathological examination confirmed it to be Giant dermatofibroma. Microscopic picture showed fibroblastic proliferation with collagen production , histiocytes and storiform pattern and focal lymphocytic infiltrates. Regular follow up showed no recurrence .This case is reported due to its very rare occurance , academic interest and to differentiate giant dermatofibroma from other such conditions such as desmoid tumor and dermofibrosarcoma protubens .
