A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step.

Solitary fibrous tumor(SFT) is a spindle cell neoplasm that usually arises in the pleura. Its involvement of the meninges is rare but increasingly being reported. Our case was a 33-year-old man who presented with clonic seizure around the right mouth angle and sensory disturbance at the right hand. Radiological studies showed a large extra-axial, dural-based mass in the left fronto-parietal region, typically isointense with gray matter and heterogeneous strong enhancement on T1-weighted images. Histologically, the tumor was composed of spindle-shaped cells growing in fascicles within the collagenous matrix. Immunohistochemical staining demonstrated diffuse CD34 positivity. Awareness of this neoplasm is necessary to accurate diagnosis.

고립성 섬유성 종양은 주로 흉막에서 발생하는 드문 종양으로 중피하 중간엽에서 기원하며 드물게 흉막 외에서 발생하기도 한다. 많은 경우에서 증상이 없이 우연히 발견되나 다른 중요 장기를 침범하거나 종양의 크기가 커질 경우 증상이 나타나기도 한다. 일반적으로 진단은 영상의학적 검사와 세침흡인을 통한 생검으로 하며 면역조직화학검사를 시행하여 더 정확히 판별할 수 있다 대부분의 경우 양성의 경과를 보이며 병변의 완전한 제거 여부가 가장 중요한 예후 인자가 된다고 알려져 있다. 저자들은 우하엽에 발생한 폐실질 내에 생긴 고립성 섬유성 종양을 채기 절제술로 치험하여 이에 보고하는 바이다

Solitary fibrous tumor (SFT) is rare mesenchymal tumor usually arising from pleura. SFT can be found at all anatomic site in our body but incidence of SFT is much lower in head and neck region especially at lower neck area. We found a case of SFT that presented as a lower neck mass in a 41-year old woman. Ultrasonography showed a 3×1cm sized hypoechoic mass in the intermuscular fat plane of left lower neck, and computed tomography showed a well circumscribed, low-density mass with contrast enhancement. Fine needle aspiration showed no malignant cells with abundant red blood cells, but it was not possible to completely rule out malignant tumors or nodules clinically. Surgery was performed to make a definitive diagnosis and histopathology showed tightly packed, round to fusiform cells with staghorn shaped vessels at microscopic examination. The tumor cell were positive for CD34 but negative for CD31 and S-100 protein.

Solitary fibrous tumor (SFT) is a neoplasm that arises most commonly in pleura. Although SFT occasionally occurs in extrapleural locations, the incidence in the oral cavity is rare. SFT is benign in almost cases and surgical excision is the effective treatment. SFT occurred in the left cheek of a 60-year-old man presented with a painless submucosal mass. The tumor was surgically removed. Immunohistochemical study showed that tumoral cells were negative for SMA, S-100, but positive for Bcl-2, CD34. SFT is easily over-diagnosed if strict criteria are not carefully applied, and strict diagnostic criteria are necessary to avoid confusion of SFT with more aggressive lesions.

Solitary fibrous tumor (SFT) is an infrequently occurring neoplasm most commonly observed in the pleura, but it can develop in the head and neck region in occasional cases. However, no reports have described SFT in the temporalis muscle. Herein, we present the first known case of SFT in the temporalis muscle. A 47-year-old man complained of a painless palpable mass on his right temple. Facial enhanced computed tomography identified a 4.0×2.9×1.4 cm mass presenting as a vascular tumor in the right temporalis muscle under the zygomatic arch. The mass was excised from the right temporalis muscle under general anesthesia. A histopathologic examination revealed that the mass was an SFT. No complications occurred after surgery, including functional disability or sensory loss. The patient was followed up for 3 months without complications. Although SFT in extrapulmonary regions is rare, it should be considered in the differential diagnosis of masses that occur in the temporal area.

A solitary fibrous tumor (SFT) is a rare neoplasm originated from the pleura, but they can occur in a variety of extrathoracic regions. Although many cases of primary SFT have been reported, there are extremely rare repots to date of a malignant SFT in the spine or skull. A 54-year-woman visited our hospital due to low back pain and both leg radiating pain. Several imaging studies including magnetic resonance imaging and computed tomography revealed expansive enhanced lesions in the occipital bone, T8, S1-2, and ilium, with neural tissue compression. We performed surgical resection of the tumor in each site, and postoperative radiosurgery and chemotherapy were performed. However, after six months, tumors were recurred and metastasized in multiple regions including whole spine and lung. The authors report here the first case of patient with malignant SFT of tandem lesions in the various bony structures, including skull, thoracic spine, and sacral spine, with a rapid recurrence and metastasis. Although malignant SFT is extremely rare, it should be considered in the differential diagnosis and carful follow-up is needed.

고립성 섬유종은 흉막에서 흔히 발생하는 양성 종양으로 알려져 있으나, 신체 어느 곳에서나 발생할 수 있고 10%-30%에서는 악성이다. 전형적으로, 고립성 섬유종은 단일성의 조영증강되는 종괴로 나타나지만, 척추 주위의 양측성 종괴로 나타나는 경우는 보고되어 있지 않다. 이 증례에서는, 등 통증과 만성 농흉의 병력이 있던 88세 남자 환자의 영상 검사에서 침습적인 양측성 척추 주위 종괴가 발견되었고, 만성 농흉과 연관된 흉부 악성 종양을 먼저 의심하였다. CT 유도하 이중구조 바늘 생검을 통해 진단된 양측성의 척추 주위 악성 고립성 섬유종의 증례를 보고한다.

악성 고립성 섬유종은 비교적 드문 종양으로 흉막, 횡격막, 후복막 및 심낭 등에서 발생할 수 있으며, 남녀 발생 빈도는 비슷하고 60~70세 사이에 호발하나 10대의 어린 나이에도 발생하는 경우가 있다. 17세 남자에서 악성 고립성 섬유종에 의해 인접한 좌측 9번째 늑골의 형태학적 변화가 있어 섬유종의 제거 및 늑골 근위부의 부분적 절제술을 시행하였다. 술 후 뇌척수액의 흉강 내로의 누출을 CT myelography로 확인 후 뇌척수액의 배액 및 부분적 반측 추궁 절제술 및 경질막 복원술을 통한 교정을 치험하여 발표하고자 한다.

Desmoid tumor (fibromatosis) is a histologically benign fibrous neoplasm showing locally infiltrating growth. This type of tumor commonly occurs in the abdomen, but intrathoracic desmoid tumor is uncommon. To date, 12 cases of intrathoracic desmoid tumor protruding into the pleural cavity, radiologically mimicking pleural masses, have been reported. Here, we report on a case of intrathoracic desmoid tumor protruding into the pleural cavity, and partially covered by parietal pleura. The main preoperative differential diagnoses included pleural solitary fibrous tumor, inflammatory pseudotumor or malignant mesothelioma. A near-total mass excision was performed. Pathologically, the tumor was composed of a paucicellular arrangement of spindle-shaped cells with fibromyxoid stroma. The resection margin was partially involved with spindle cells present. On histochemical staining, the spindle cells were strongly positive for vimentin and negative for CD34, consistent with a desmoid tumor. The patient was stable without further adjuvant treatment during 6-years of follow-up.
