Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor that can develop in numerous organs, most commonly in the lungs and rarely in the brain. Here, we reported a 55-year-old patient with nasopharyngeal IMT and the recurrence in the skull base, slope and pterygoid sinus who underwent cranial base and slope tumor resection. Postoperative magnetic resonance imaging (MRI) and multiplex immunohistochemistry (mIHC) showed tumor recurrence and metastasis to the intracalvarium. While genetic testing revealed no significant related gene mutations, tertiary mutations in NSD1 and SOX9 genes were identified in the tumor tissues. The patient achieved partial remission after receiving 7 cycles of immunotherapy (toripalimab 240 mg for 1 cycle followed by 6 cycles of sintilimab 200 mg), and MRI examination indicated an almost complete remission of intracranial IMT after 16 cycles of immunotherapy. In summary, the novel class of immune-targeted agents may be effective in clinical management of rare intracranial IMT.

Uterine Inflammatory Myofibroblastic Neoplasms With Aggressive Behavior, Including an Epithelioid Inflammatory Myofibroblastic Sarcoma: A Clinicopathologic Study of 9 Cases. Am J Surg Pathol 2021; 46:105-117. [PMID: 34138797 DOI: 10.1097/pas.0000000000001756] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
The experience with uterine inflammatory myofibroblastic neoplasms with an unfavorable outcome is limited. We present the clinicopathologic features of 9 such cases, including 8 inflammatory myofibroblastic tumors (IMTs) and 1 epithelioid inflammatory myofibroblastic sarcoma (EIMS). Median patient age for the IMT group was 50.5 years; the patient with EIMS was 43 years old. Patients presented with abnormal uterine bleeding, presumed fibroids, pelvic pain, arthralgia and low-grade fever, as well as an incidental finding. Median tumor size for the IMTs was 8.5 cm. The borders were either infiltrative or well-circumscribed. Histologically, IMTs were purely fascicular or myxoid or showed predominance of one or the other pattern. Seven tumors were spindled, and 1 was both spindled and epithelioid. Tumors had variable nuclear atypia, ranging from grade 1 to 3. All tumors had an inflammatory infiltrate-predominantly lymphocytic, majority had necrosis (62.5%) and none had lymphovascular invasion. 7/8 (87.5%) tumors were positive for ALK-1 by immunohistochemistry (IHC). One tumor was negative for ALK-1 by IHC but was positive for ALK fusion by fluorescence in situ hybridization and had TNS1-ALK fusion by next-generation sequencing (NGS). Three other tumors with NGS testing showed one of the following ALK-fusion partners: FN1, DCTN1, and IGFBP5. The EIMS had infiltrative borders, myxoid and hyalinized patterns, epithelioid cells, and no lymphovascular invasion. This tumor was ALK-1 positive by IHC, had ALK rearrangement by fluorescence in situ hybridization and RANBP2-ALK fusion by NGS. Extrauterine disease at time of diagnosis was noted in 2/8 (25%) of IMTs, and in the single case of EIMS. Seven patients had surgery as primary treatment, 1 patient had neoadjuvant chemotherapy and 1 patient declined treatment. Patients with recurrence were treated with a combination of chemotherapy, targeted therapy, radiotherapy or hormonal therapy. Most patients (71.4%) recurred within 24 months (mos). Two thirds of patients were alive with disease at last follow up (mean 43.6 mos). The patient with EIMS was alive with disease at 22 mos. IMT referral cases were initially diagnosed as smooth muscle tumors in 87.5% of cases; while the EIMS was diagnosed as high-grade endometrial stromal sarcoma. Lack of consideration of IMT in the differential diagnosis of smooth muscle tumors with myxoid features can result in misdiagnosis and under-utilization of targeted therapy in these patients.

Abstract
A 17-year-old girl presented to her primary care physician with a history of unintentional weight loss and vague sensory symptoms, including tingling of her lower extremities. She had a nonrevealing neurology workup and a largely normal rheumatology workup apart from mild elevation in her inflammatory markers. She also had a nonfocal examination apart from a posterior cervical lymph node (2 × 1 cm). Given that she was well appearing, with a nonfocal examination and only mild laboratory abnormalities, she was told to follow-up with rheumatology in 3 months. Around that time, she re-presented to her medical home for a well-child visit, during which she was noted to have continued weight loss, now amounting to 17 lb in 1 year, and marked further elevation in her inflammatory markers. Her laboratory results were also significant for a profound microcytic anemia requiring inpatient admission for blood transfusion. During her admission, she was seen by the rheumatology, gastroenterology, and oncology subspecialty teams. Despite imaging studies and extensive laboratory workup, there was no unifying diagnosis at the time of her hospital discharge. Ultimately, an outpatient imaging study revealed the etiology.

Inflammatory myofibroblastic tumors of the breast with simultaneous intracranial, lung, and pancreas involvement: ultrasonographic findings and a review of the literature.

Abstract
We encountered a case of inflammatory myofibroblastic tumor (IMT) of the breast with simultaneous intracranial, lung, and pancreas involvement. Here, we present the clinical imaging results and report the significance of sonographic findings of breast IMT along with a review of the literature. A 16-year-old girl with a history of subarachnoidal hemorrhage was admitted to our hospital due to tonic-clonic seizure. Computed tomography (CT) and magnetic resonance imaging (MRI) showed multiple intracranial, lung, and pancreas mass lesions and a solitary mass lesion in the right breast. Breast ultrasonography showed a circumscribed oval-shaped hypoechoic mass with a central hyperechoic region. Power Doppler sonography revealed an unusual spiral-shaped flow signal. Breast tumorectomy was performed for definitive diagnosis, and pathological analysis indicated IMT. A literature review indicated that ultrasonographic findings of IMT of the breast are nonspecific, as in other systems or organs. It would be difficult to make a diagnosis of IMT of the breast preoperatively due to its rarity and the lack of specificity of clinical imaging findings. In addition, it is better to consider the possibility of IMT of the breast especially in younger patients without an obvious family history of hereditary breast cancer.
