Fibroma of tendon sheath of the hand: Clinical and pathological study

Fibroma of Flexor Tendon Sheath of Finger: A Rare Tumor of Hand-Revisited

“…The differential diagnosis of fibroma of tendon sheath includes several clinical conditions, summarized in Table 1 [7,[12][13][14]. FTS is most often confused with giant cell tumor (GCT) of the tendon sheath.…”

“…Often dilated or slit-like channels/clefts resembling tenosynovial spaces are present. It may have bizarre tumor cells, extravasated red blood cells, but atypical mitotic figures, necrosis, hyperchromasia, osteoclasts, giant cells and siderophages are typically absent [7,16,19,20].…”

“…Treatment of FTS is complete local excision with preservation of the surrounding vital structures particularly neurovascular bundles. Recurrences tend to occur between one month and two years postoperatively, and may be related to pseudopod formation and separate tumor foci in adjacent connective tissue and/or remnants of these foci after initial surgery [7].…”

“…The predilection for specific digits of right hand and the finding of fasciitis like areas in some cases suggest a possible reactive origin [6]. Microtrauma of the hand by routine manual labor has also been suggested as predisposing factor [7]. Surgical excision is the mainstay of the treatment but it should be done with great care, as recurrence is more common in hands and fingers with as high rate as 24% [8].…”
