Painless soft tissue lumps in fingers and toes

Introduction The painless soft tissue mass of the fingers and toes belongs to the lesion of the giant cell tumor of the tendon sheath. Slow growth, usually less than 3 cm, occurs on the fingers and hands, and the toes are rare. Tumors can erode adjacent bones. Young people are more common, more women than men. The average age of onset is 30 years old. The pathogenesis is still unclear. Because there are hemosiderin and lipid-like deposits in the tumor tissue, it is often yellow-brown, so it is also called yellow tumor. The cause is unknown and may be related to trauma, inflammation and cholesterol metabolism disorders. This tumor is often lobulated. The leaflets are surrounded by dense, clear collagen. The intratumoral cells are composed of tissue-like mononuclear cells, osteogenic multinucleated giant cells, xanthoma cells, chronic inflammatory cells, hemosiderin macrophages and collagenized matrix mixed in different proportions.

Skin lesion

The lesions of giant cell tumor of tendon sheath are solid, painless masses, which grow slowly, usually less than 3 cm, occurring on the fingers and hands, and the toes are rare. Young people are more common, more women than men. Tumors can erode adjacent bones. Approximately 25% of cases relapse after resection, and very rare malignant tendon sheath giant cell tumors have also been reported. Another ganglion sheath, the tendon sheath fibroma, may be a subtype of tendon sheath giant cells that also invades the flexor tendon of the fingers and hands. The clinical morphology is the same as that of giant cell tendon sheath tumors. The average age of onset is 30 years old, which is younger than the age of giant cell sheathoma. .

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.

Differential diagnosis

It should be differentiated from the symptoms of other lumps of the fingers or toes.

The skin lesion of the giant cell tumor of the tendon sheath is a solid, painless mass that grows slowly, usually less than 3 cm, and occurs on the fingers and hands, and the toes are rare. Young people are more common, more women than men. Tumors can erode adjacent bones. Approximately 25% of cases relapse after resection, and very rare malignant tendon sheath giant cell tumors have also been reported. Another sphincter tumor, the fibroma of the tendon sheath, may be a subtype of the giant cell of the tendon sheath and also invade the flexor tendon of the finger and hand. The clinical morphology is the same as that of the giant cell tendon sheath. The average age of onset is 30 years old, which is larger than the giant cell. The age of onset of tendon sheath is mild. According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
