  • Purpose: To evaluate the imaging findings of desmoid tumors using various imaging modalities and to evaluate whether diffusion-weighted imaging (DWI) can help differentiate between desmoid and malignant tumors. Materials and Methods: The study included 27 patients with pathologically confirmed desmoid tumors. Two radiologists reviewed 23 computed tomography (CT), 12 magnetic resonance imaging (MRI) and 8 positron emission tomography-computed tomography (PET-CT) scans of desmoid tumors and recorded data regarding the shape, multiplicity, size, location, degree of enhancement, and presence or absence of calcification or hemorrhage. The signal intensity of masses on T1- and T2-weighted imaging and the presence or absence of whirling or band-like low signal intensity on T2-weighted imaging were recorded. The apparent diffusion coefficient (ADC) values of the desmoid tumors in nine patients with DWIs were compared with the ADC values of 32 malignant tumors. The maximum standardized uptake value ($SUV_{max}$) on PET-CT images was measured in 8 patients who underwent a PET-CT. Results: The mean size of the 27 tumors was 6.77 cm (range, 2.5-26 cm) and four tumors exhibited multiplicity. The desmoid tumors were classified by shape as either mass forming (n = 18), infiltrative (n = 4), or combined (n = 5). The location of the tumors was either intra-abdominal (n = 15), within the abdominal wall (n = 8) or extra-abdominal (n = 4). Among the 27 tumors, 21 showed moderate to marked enhancement and 22 showed homogeneous enhancement. Two tumors showed calcifications and one displayed hemorrhage. Eleven of the 12 MR T2-weighted images showed whirling or band-like low signal intensity areas in the mass. The mean ADC value of the desmoid tumors ($1493{\times}10^{-6}mm^2/s$) was significantly higher than the mean of the malignant soft tissue tumors ($873{\times}10^{-6}mm^2/s$, P < 0.001). On the PET-CT images, all tumors exhibited an intermediate $SUV_{max}$ (mean, 3.7; range, 2.3-4.5). Conclusion: Desmoids tumors showed homogenous, moderate to marked enhancement on CT and MRI scans and a characteristic whirling or band-like pattern on T2-weighted images. DWI can be useful for the differentiation of desmoid tumors from malignant soft tissue tumors.

  • 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.

  • Desmoid tumors are rare soft tissue tumors considered to have locally infiltrative features without distant metastasis until now. Although they are most commonly intraabdominal, very few cases have extra-abdominal locations. The origin of intrathoracic desmoid tumors is predominantly the chest wall with occasional involvement of pleura. True intrathoracic primary desmoid tumors with no involvement of the chest wall or pleura are extremely rare. We recently experienced a case of true intrathoracic desmoid tumor presenting as multiple lung nodules at 13 years after resection of a previous intraabdominal desmoid tumor.

  • 데스모이드 종양은 섬유아세포양 증식을 특징으로 하는 심부 섬유종증으로 조직학적으로 양성이지만 침습적인 성장 양상과 높은 재발율을 보인다. 방사선학적으로 초음파상 경계가 비교적 뚜렷한 고형종괴로 보이며 내부의 에코는 비특이적이며 CT 소견상 근섬유의 주행방향을 따라 길쭉한 모양을 보이고 조영제 주입전에는 주변 근육과 비슷한 등음영 또는 약간 저음영을 보이고 조영후에는 시간이 감에 따라 점차 조영증강되는 소견을 보인다. 저자들은 급속조영 CT를 시행하여 시간에 따른 조영 양상을 관찰함으로써 종괴의 조직학적 구성을 짐작할 수 있었고 병리조직학적으로 확진된 데스모이드 종양 2례를 경험하였기에 보고하는 바이다.

  • Objective: To demonstrate the feasibility of percutaneous microwave ablation in desmoid fibromatosis with respect to tumor volume control and improvement in the quality of life. Materials and Methods: Twelve microwave ablations were performed in 9 patients with a histological diagnosis of desmoid fibromatosis between January 2010 and January 2019. The study population included 6 female and 3 male, with an age range of 21-76 years (mean = 46.6 years; standard deviation [SD] = 19.3 years). The mean major axis of the tumors was 10.9 cm (SD = 5.2 cm) and mean lesion volume was 212.7 cm3 (SD = 213 cm3). Their anatomical distribution was as follows: 3 lesions in the thigh, 2 in the gluteus, 2 in the leg and 2 in the periscapular region. We evaluated the reduction in tumor volume and improvement in the quality of life based on the Eastern Cooperative Oncology Group (ECOG) scale. Results: An average tumor volume reduction of 70.4% (SD = 24.9) was achieved, while the quality of life (ECOG scale) improved in 88.9% of patients. Conclusion: Percutaneous microwave ablation may potentially be a safe, effective, and promising technique for controlling tumor volume and improving the quality of life in patients with desmoid fibromatosis.

  • The desmoid tumor has been reported as the most common histologic subtype of soft tissue sarcoma occuring in chest wall and it known to be highly recurrent. The treatment of choice is a radical wide resection including a safe margin of uninvolved structures around the grossly visible tumor. We report a case of chest wall reconstruction using Marlex sandwich and latissimus dorsi musculocutaneous flap after wide resection of desmoid tumor on the chest wall.

  • A 66 years old female who had a huge desmoid tumor on her left neck was treated by partial excision and postoperative irradiation. Detailed summary of this rare tumor are included with a review of the literature about treatment modality including irradiation. We suggest that local irradiation is one of the effective treatment tools in the management of desmoid tumor, especially, in the case of unresectable or postoperative residual tumors on the neck.

  • 데스모이드 종양은 조직학적으로 양성이지만 임상적으로는 악성으로 취급된다. 완전절제가 최선이고 재발 시에도 재절제를 시행하는 것이 권장된다. 본원에서는 흉부에 발생한 데스모이드 종양에 대한 재발 2예를 경험하였고 재수술로써 완전히 절제하였다. 두 환자 모두 수술 후 양호한 경과를 보여 퇴원하였고, 현재는 특이 합병증 및 재발 없이 외래 관찰 중이다. 이에 문헌 고찰과 함께 보고하는 바이다.

  • Desmoid tumor is found most often in the anterior abdominal wall of parous women. Although it may originate in virtually any musculotendinous structure, those of the chest wall are rare. We experienced a case of large dumb bell shaped desmoid tumor originated in intercostal muscle and invaded anterior chest wall, pericardium, pleura and the lung. The patient was healthy in appearance except a painful swelling on the anterior chest wall. Roentgenographic studies demonstrated a huge homogenous mass in the right anterior chest cavity. He was treated with resection of the tumor including .anterior chest wall, a portion of the pericardium, middle lobe, and part of upper & lower lobes of the right lung because of tumor invasion. The tumor composed with two parts, one [$5{\times}4{\times}3$cm in size] is over the rib cage and another [$10{\times}15{\times}10$cm in size] is in the right chest cavity. Postoperative course was uneventful and there was no evidence of recurrence until last visit, 5 months after surgery.
