Rational: Low-grade myofibroblastic sarcoma (LGMS) is an atypical type of tumor composed of myofibroblasts. LGMS in the femoral head neck junction is extremely rare and no case treated by hip arthroscopy was reported. Patient concerns: We reported a case of LGMS in the femoral head neck junction treated by hip arthroscopy. A 30-year-old female was admitted to our hospital with discomfort and pain after left hip sprained one year prior. Physical examination revealed swelling of the left hip and magnetic resonance images showed a soft tissue mass in the femoral head neck junction. Diagnosis: Via microscopy of pathological specimens, spindle cell proliferative lesions, atypia of some cells, and mitotic figures/pathological mitotic figures of some cells were observed. Immunohistochemistry revealed positive for smooth muscle actin, focally positive for CD34 and CD68, while negative for S-100, desmin, and anaplastic lymphoma kinase. The imaging, histomorphological and immunohistochemical features suggested a final diagnosis of LGMS of the proximal femur. Interventions: This patient underwent hip arthroscopy for excision of the soft tissue mass. Outcomes: The clinical and imaging follow-up at 6 months postoperatively showed that surgery had achieved good clinical outcomes. Lessons: To the best of our knowledge, this is the first case report of LGMS in the femoral head neck junction treated by hip arthroscopy. Beyond the present case, other 120 cases from 58 literatures (1998–2022) are reviewed and discussed. The age of LGMS patients ranged from 11 months to 77 years and the male-to-female ratio was approximately 1.28:1. The location distribution of previously reported LGMS cases and the present case was as follows: Head&neck (45.90%), trunk (30.33%), and extremity (23.77%). Hip arthroscopic excision of LGMS may achieve relatively good clinical outcomes.

“…MRI revealed that T1weighted image (WI) signal was mostly an equal signal, T2WI signal was an iso-to-high signal [ 22 , 37 , 41 , 44 ]. Gadolinium enhancement T1WI showed enhancement of the tumor [ 22 , 41 ]. The border of the tumor on the MRI was varied; some author reported well demarcated tumor [ 7 , 13 , 44 ], but the others were ill-defined [ 10 , 41 , 42 ].…”

Background Low-grade myofibroblastic sarcoma (LGMS) is described as a distinct atypical myofibroblastic tumor often with fibromatosis-like features and predilection for the head and neck, especially the oral cavity and larynx. LGMS arising in the levator scapulae muscle is extremely rare. Case presentation A 69-year-old woman was admitted to our hospital because she noticed a hard mass in her left neck six months prior. Magnetic resonance images (MRI) showed a soft tissue tumor of the left levator scapulae muscle. A core needle biopsy showed cellular fascicles or a storiform growth pattern of spindle-shaped tumor cells with minimally atypia. Immunohistochemistry revealed focally positive for α-smooth muscle actin (α-SMA), negative for S-100, and a low-grade spindle cell sarcoma was suspected. Following a biopsy, the tumor was resected with a wide surgical margin. Immunohistochemical staining was a positive for vimentin and α-SMA and negative for desmin, CD34, nuclear β-catenin, and h-caldesmon. LGMS diagnosis was determined based on the histopathological findings. The patient was alive with no evidence of disease eight years after the surgery. Conclusions To the best of our knowledge, this is the first case report of LGMS arising in the levator scapulae muscle. In addition to the case report, 48 reports with 103 LGMS cases are reviewed and discussed. In previous reports of LGMS, there were 43 females and 60 males, with a mean age of 43.0 years (range, 2–75). There were 13 (12.6%) patients aged < 18 years, 67 (65.1%) patients aged 18 to 59 years, and 23 (22.3%) patients aged ≥60 years. The average tumor size was 4.4 cm (range: 0.4–22.0). The commonest sites of LGMS was the tongue. Tumor growth patterns were evaluated in 52 cases, and 44 cases (84.6%) showed infiltrative growth patterns. Local recurrence was 26.7%, and distant metastasis was 4.4%. Because of the locally aggressive feature, it is important to diagnose LGMS with biopsy and to excise the tumor with an adequately wide margin.

“…LGMS imaging also lacks characteristics of the most common CT and MRI manifestation as follows: mostly single lumps, lobulated or irregular type, a small number of tumor have clear border, mostly invasive growth, easy to infiltrate adjacent fat, fibrous and muscle tissues, visible necrosis and calcification; CT scan: non-contrast enhanced scan reveals uneven or lower density, and contrast enhanced scan reveals the uniform or thick-walled ring enhancement and mostly delayed enhancement [ 6 ] ; MRI characteristics: T1WI signal is mostly equal signal, T2WI signal is mostly slightly higher signal, the signal is not uniform, and there are cable-like signals. [ 7 ] Regarding to the 18 F-FDG PET/CT scan of LGMS, only Morii et al [ 8 ] have reported a case of back (left split muscle) LGMS, in which abnormally increased FDG metabolism can be seen in the lesions with an SUVmax of 9.8.…”

Rationale:Low-grade myofibroblastic sarcoma (LGMS) is a rare mesenchyme-derived tumor, which usually occurs in head, neck (especially tongue and mouth), and limbs. In this report, we described a case of gastric LGMS by 18F-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography/computed tomography (PET/CT), which has not been reported previously.Patient concerns:A 51-year-old female patient was admitted to our hospital with upper abdominal discomfort for 1 year and gradually increased eating difficulties over the last 3 months. From gastroscopy, an ulcer of 1.0 cm × 1.2 cm at the entrance of cardia and stiffness of peripheral mucosa were found, leading to suspicion of cardia cancer. 18F-FDG PET/CT was performed for further diagnosis and staging.Diagnoses:According to pathological findings in combination with immunohistochemical features, diagnosis of gastric LGMS was made.Interventions:To relieve symptoms of upper gastrointestinal obstruction in the patient, proximal gastrectomy was carried out 1 week after the 18F-FDG PET/CT scan.Outcomes:The patient died due to advanced tumor.Lessons:18F-FDG PET/CT scan showed local thickening of the gastric wall, invasion of adjacent soft tissue, diaphragmatic and peritoneal metastasis at early stage, absence of regional lymph node metastasis, and increased 18F-FDG metabolism in primary tumor and metastatic tumor.
