Giant Cell Tumor of Tendon Sheath – A Cyto Histo Correlation

Giant cell tumor of the tendon sheath (GCTTS) is a slowly progressing benign tumor
arising from synovial cells of tendon sheaths. Chas-saignac first described the soft tissue
mass in 1852. Hand is more frequently involved than any other part of the body. In fact it
is a rare primary tumor of hand but is second most common among the soft tissue tumors
of the hand. They occur more commonly on the palmar side of the hand. The age
distribution is 8 to 80 years but is more common between 30 to 50 years. Female:male
ratio is 3:2. They are usually non tender. Movements are usually not interfered and rarely
erode the bone.Here we present a case of GCTTS in a 35 year old female patient over the
right hand index finger which was diagnosed cytologically and histologically. History of
recurrence also present in the present case.
