OBJECTIVETo investigate diagnostic methods and surgical effect for the treatment of giant cell tumor of tendinous sheath in wrist.

METHODSFrom September 2002 to October 2009, 8 patients with preoperative diagnosis as giant cell tumor of tendinous sheath based on MRI were treated surgically. There were 5 males and 3 females, ranging in age from 16 to 65 years, with an average of 41 years. The disease course ranged from 10 to 72 months with an average of 31 months.

RESULTSThe diagnosis of all the patients was confirmed as giant cell tumor of tendinous sheath by postoperative pathology. All the patients were followed up, and the during ranged from 5 to 48 months (averaged, 34.2 months). One patient recurred and 3 patients got obvious relief of symptoms of median nerve injury. All the patients had significant improvement in wrist function after surgery.

CONCLUSIONPreoperative MRI is helpful for differential diagnosis of giant cell tumor of tendinous sheath. Thorough removal of tumor is very important in prevention of recurrence.

Low-grade fibromyxoid sarcoma is a slowly growing soft tissue neoplasm that shows benign histologic features but may have clinical course of malignant disease. It has been reported to occur in the thigh, inguinal area, axilla, shoulder, neck, perineum or buttock. However, there have been few cases of abdominal organ involvement. A 21-year-old woman presented with a large palpable abdominal mass. A 7x4 cm sized round soft tissue tumor at right upper quadrant area was identified by abdominopelvic CT scan. Percutaneous ultrasound-guided biopsy revealed features of spindle cell tumor. On exploration, the tumor originated from transvers colon and was attached to gastrocolic ligament, transverse mesocolon and stomach. The tumor could be dissected with transverse colectomy and partial gastrectomy. The excised tumor, measuring 7x5x5 cm, was well demarcated and appeared as an ovoid mass with firm and myxoid cut surface. She was diagnosed with low-grade fibromyxoid sarcoma arising from transverse colon, and is currently being followed-up without recurrence or metastasis.

Infantile hemangiomas are relatively common soft tissue tumors in infants and young children, with a prevalence of about 4.5% in full-term newborns. Subglottic Hemangioma （SGH） is a relatively rare type of hemangioma, and its special location often causes respiratory distress and potentially life-threatening conditions in infants. Therefore, it is necessary for clinicians to make an accurate diagnosis and formulate a detailed treatment plan based on the clinical manifestations, the auxiliary examinations, the medical history and the vital signs evaluation of patients.This review describes the pathophysiological mechanism of infantile hemangioma and provides a detailed discussion on commonly used treatment methods in detail.

Nodular fasciitis is a benign, reactive myofibroblastic tumor that is often mistaken for a sarcoma because of its histological appearance and rapid growth. Involvement of a finger is extremely rare. We report a case of nodular fasciitis of the thumb, accompanied by bone erosion. Magnetic resonance findings suggested the possibility of a malignancy, which could have led to misdiagnosis as a malignant soft tissue sarcoma. Instead, the lesion was treated by excisional biopsy, which confirmed nodular fasciitis. There has been no evidence of local recurrence at recent follow-up, 1 year after surgery. This case illustrates that, to avoid unnecessarily aggressive surgery, nodular fasciitis must be included in the differential diagnosis for any finger lesion that resembles a sarcoma, even if bone erosion is present.

We report the case of a giant cell tumor with diffuse interstitial hemorrhaging and unusually prominent cystic components in the soft tissue of the thigh which has not been reported previously. Magnetic resonance image (MRI), showed signal intensity typical of a giant cell tumor. However, because of its conspicuous large well-circumscribed cystic components, the differential diagnoses, based on the image findings from an ultrasonography (US) and MRI, were complicated epidermoid cyst, cystic change of a neurogenic tumor, and a parasitic cyst.

OBJECTIVETo introduce the clinical features of a rare malignant soft tissue tumor.

METHODSReview the clinical findings, pathologic features and results of the treatment of 16 cases of the epithelioid sarcoma in extremities, which were treated in our hospital from 1992 to 2004. Analyze the follow-up results of 14 cases.

RESULTSThe tumors occurred chiefly in young adults (mean age 30 years) and commonly involved soft tissue of the hand. Follow-up (average 25 months, from 1 to 112 months) information on 14 patients revealed relentless clinical course with frequent recurrence (71%). There was a significant difference between those patients in whom had a marginal and radical resection, both in recurrence rate and disease-free survival rate.

CONCLUSIONIt is safe to choose the radical resection of this disease after the tumor reoccurs.
