Desmoid tumors (DTs) are rare benign neoplasms but cause significant mortality due to their locally infiltrative nature and propensity to recur. Most DTs occur in the extremities and trunk. Head and neck DTs are uncommon but can have a significant impact on a patient\'s facial appearance. However, there is limited information available about the diagnosis and treatment for multiple DTs located in head and neck. We report the first case of multiple maxillofacial DTs in a 14-year-old boy. He had painless submandibular masses for three months and MRI imaging reveals abnormal high signals on the submandibular and bilateral zygomatic regions. Considering facial aesthetics, via intraoral incision we obtained a biopsy from the largest mass. Pathological examination confirmed a diagnosis of DT. We selected the wait-and-see strategy and clinically monitored the rest of the masses. During the subsequent 1-year follow-up, the masses were stagnant and appeared to involute. According to the development and outcome of this case, a conservative treatment for craniofacial DTs is suggested; however, greater clarity concerning management and prognosis could derive from prospective study of a larger patient cohort in the future.

UNASSIGNED: Desmoid-type fibromatosis (DF) is characterized by a rare monoclonal fibroblast proliferation that exhibits variable and unpredictable clinical presentation. DF can be classified into sporadic and hereditary types. Despite extensive research efforts, the exact etiology of DF remains elusive.
UNASSIGNED: A 31-year-old male patient presented to the hospital with a progressively growing mass in the right lower abdomen, accompanied by abdominal discomfort. Symptoms are discovered 1 week before admission. Enteroscopy revealed no evidence of colonic abnormalities, and blood tests did not indicate any abnormalities. Due to the indeterminate nature of the mass during surgery, a partial resection of the ileum and cecum was performed, followed by ileocolonic end-to-end anastomosis, with no postoperative complications. The final pathological diagnosis confirmed primary desmoid-type fibromatosis of the distal ileum (invasive fibromatosis). To effectively manage DF, we recommend a follow-up schedule for patients. This includes appointments every 3 months in the first year following surgery, followed by appointments every 6 months up to the fifth year, and then once a year thereafter. The follow-up examinations should include collection of the patient\'s medical history, physical examination, blood tests, ultrasounds, CT scans, and other relevant assessments. During the first year of the follow-up period, no further treatment was administered, and the patient remained disease-free.
UNASSIGNED: Desmoid-type fibromatosis (DF) originating from the small intestine is an extremely rare condition that exhibits local invasiveness and can be life-threatening. Despite its benign histology, DF has a high local recurrence rate and lacks metastatic potential. Diagnosis of DF remains challenging, especially in cases where surgical intervention is not feasible due to asymptomatic patients or partial organ impairment. In such cases, a \"watchful waiting\" approach is recommended as the initial treatment strategy. However, when preoperative diagnosis is difficult, surgery is typically considered the best option. Given the potential for local recurrence and the uncertain long-term prognosis, regular follow-up is necessary.

Aggressive fibromatosis (AF), also known as ligamentoid fibromatosis and desmoid tumor, is a fibroblast clonoproliferative lesion located in the deep soft tissue. The present study reports the case of a 36-year-old female with AF who underwent cervical spinal cord ependymoma surgery. AF developed in the soft tissue of the neck adjacent to the incision site. The size of the neck AF increased rapidly over 2 years, and due to discomfort, the patient underwent initial surgical resection without any other combined treatment methods. When the patient was routinely reviewed at 6 months post-surgery, a recurrence of AF of the neck was found. The patient was recommended surgical resection and radiotherapy. This case report should improve the understanding of clinicians with regard to AF, and help the diagnostic process and treatment plan.

OBJECTIVE: Although the treatment of abdominal wall desmoid-type fibromatosis (DF) has evolved over the past decades, surgical treatment remains an important approach. Previously, surgeries for abdominal DF were mostly performed by laparotomy, which involves massive dissection and significant trauma. Here, we report our single-center experience of the laparoscopic management of abdominal wall DF in young female patients.
METHODS: The clinical data of nine patients diagnosed with abdominal wall DF during January 2020-April 2022 at the Qilu Hospital of Shandong University were retrospectively analyzed. All patients underwent laparoscopic resection of abdominal wall DF and immediate abdominal wall reconstruction (AWR) with mesh augmentation via the intraperitoneal onlay mesh (IPOM) technique.
RESULTS: Laparoscopic DF resection and AWR were successfully performed in all patients. The mean operation time was 175.56 ± 46.20 min. The width of abdominal wall defect was 8.61 ± 3.30 cm. Full- and partial-thickness myofascial closure and reapproximation were performed in five, two, and two patients, respectively. The average mesh size was 253.33 ± 71.01 cm2. The total and postoperative lengths of hospital stay were 11.00 ± 3.46 and 4.89 ± 2.03 days, respectively. Tumor recurred in one patient after 20 months of the resection. Nonetheless, death, herniation, or bulging were not observed in any patient during a mean follow-up of 16.11 ± 8.43 months.
CONCLUSIONS: Laparoscopic resection of abdominal wall DF and immediate AWR with IPOM mesh reinforcement is safe and reliable for young female patients. Management of such patients should be decided according to the biological behavior, size, and location of tumors.

UNASSIGNED: A giant abdominal tumor with a large hiatal hernia remains a rare disease with few studies regarding its implications in anesthesia. A large hiatal hernia may compress the heart and cause arrhythmia and even cardiac arrest, which greatly increases the risks and challenges of anesthesia management.
UNASSIGNED: We present a case in which a patient with a giant abdominal desmoid tumor and large hiatal hernia experienced a critical situation during anesthesia and surgery.
UNASSIGNED: It is a great challenge for anesthesiologists to manage a patient\'s respiratory system and circulation. Careful perioperative management and optimized multidisciplinary teams are the key factors in the successful management of this rare condition. In addition, awake endotracheal intubation, ventilation preserving spontaneous breathing and target-directed fluid therapy play an essential role in anesthesia management.

UNASSIGNED: There are lacking standard treatment guidelines for aggressive fibromatosis (AF) because of its rarity.
UNASSIGNED: This study aimed to investigate the risk factors for recurrence and survival of abdominal AF after radical surgical resection.
UNASSIGNED: From August 2012 to December 2020, a retrospective analysis was conducted on the clinical data of 69 AF in Shanghai Public Health Clinical Center Affiliated to Fudan University, with the tumor locating either in the abdominal wall or in the abdominal cavity. The main observation end point was progression-free survival time (PFS) and overall survival time (OS).
UNASSIGNED: All 69 patients achieved microscopic R0 resection, 10 (14.5%) had local recurrence, and 3 (4.3%) died. The PFS rate after 1, 3, 5, and 10 years was 96.8%, 87.7%, 78.8%, and 78.8%, respectively. The OS rate after 1, 3, 5, and 10 years was 100%, 100%, 92.9%, and 81.3%, respectively. In 10 patients with recurrence, the median recurrence time was 17.6 months. Concomitant familial adenomatous polyposis (FAP) and history of previous recurrence were independent risk factors of post-operative recurrence.
UNASSIGNED: After radical surgery of abdominal AF, the local recurrence rate was 15%. Concomitant FAP and a previous history of recurrence were independent risk factors of post-operative recurrence. R0 and a combined organ resection should be performed especially in FAP patients to minimize the recurrence and improve the prognosis.
UNASSIGNED: The present study identifies the risk factors of recurrence in AF and suggests R0 resection especially in concomitant FAP patients. A wait-and-see strategy should not be generally implemented and radical surgery will bring clinical benefits to patients with such kind of rare disease.

Desmoid tumors are rare neoplasms that are locally invasive. However, optimal treatment strategies for recurrent desmoid tumors remain controversial. High-intensity focused ultrasound (HIFU) has been reported as a noninvasive modality for treating recurrent desmoid tumors. However, its efficacy against massive desmoid tumors or those with complex anatomies remains unclear.
We developed a new therapeutic strategy called low-power cumulative HIFU and applied it to treat recurrent desmoid tumors.
We retrospectively collected data from 91 patients with recurrent desmoid tumors who underwent low-power cumulative HIFU treatment after surgical treatment failure. The mean ablation proportion of the HIFU treatment was 69.5%, and the objective response rate was 47.3%. The 5-year estimated progression-free survival rate for these patients was 69.3%.
Low-power cumulative HIFU treatment could achieve significant efficacy and long-term control of recurrent desmoid tumors.
