Nodular fasciitis is a reactive, non-neoplastic lesion that is most commonly found in the subcutaneous or superficial fascia of the extremities and trunk. Head and neck lesions are relatively uncommon and reports vary from 7% to 15% depending on the authors. Nodular fasciitis grows quickly, and shows a pleomorphic spindle cell pattern with increased mitotic activity. Such factors lead to cases where the lesion is mistaken for a malignancy such as fibrosarcoma and the case may end up with unnecessarily aggressive treatments. The intent of this paper is to report a relatively rare case of nodular fasciitis occurring in the periorbital area and also to highlight the importance of accurate diagnosis and non-aggressive management of this benign lesion.

Nodular fasciitis is an unusual benign tumor which is composed of myofibroblast. Typical histologic findings include haphazardly arranged pleomorphic arranged spindle cells in a myxoid stroma. These lesions may easily be misinterpreted as malignancy clinically and histologically because it presents as a rapidly growing mass from subcutaneous or deep fascia. These lesions are usually located over upper extremity and rarely in the head and neck region. It's important to emphasize the need of clinical suspicion and accurate histopathology of this rare benign lesion usually misdiagnosed as a malignacy to avoid unnecessary and inappropriate aggressive wide resection, when encountering subcutaneous nodules of the face and neck region. In this article, we report a rare case of Nodular fasciitis on the Nose and some reviews of the literature.

Nodular fasciitis is a benign reactive proliferation that usually involves the deep fascia. Although it is relatively common in the adult population, it is often misdiagnosed as sarcoma due to its rapid growth and pathological features. It rarely presents as a chest wall tumor in young patients. Here, we report a case of nodular fasciitis involving the chest wall of an 18-year-old woman and its surgical management. This case underscores the need to consider nodular fasciitis in the differential diagnosis of chest wall tumors in young patients.

Nodular faciitis is generally considered to be benign proliferation of fibroblasts and myoblasts, and it measures dimension up to 3cm. The characteristics such as rapid growth, abundant cellularity, and mitotic activity occasionally cause these lesions to mimic sarcoma. The authors experienced two cases of nodular fasciitis of the thigh, which were unusually large with dimension of more than 5cm. All of these two cases mimicked sarcoma and one of two cases, which initially mimicked sarcoma clinically and histologically in our hospital, was finally diagnosed as nodular fasciitis after requesting external consultation to several experienced pathologists. All of two cases had no evidence of recurrence at 2 years postoperatively. The lesions of unusually large dimension such as in our cases must be included in the differential diagnosis of soft tissue sarcoma. So we report two cases of nodular fasciitis of the thigh with a review of the current literature.

A 25 years old male patient with Hodgkin's disease, considered as complete remission, underwent $^{18}F$-FDG whole body PET/CT. $^{18}F$-FDG whule body PET/CT showed unexpected hypermetabolic nodule in left quadratus femoris muscle suggesting local recurrence. Subsequent MRI also revealed well-enhancing nodular lesion with intermediate and high signal intensity on T1WI and T2WI, respectively. The lesion was confirmed as nodular fasciitis by pathologic examination of the excited specimen.

Nodular fasciitis is a benign fibroblastic proliferation rarely reported in the breast. We report the case of a 55-year-old woman who presented with imaging findings that resembled a malignancy. Mammography revealed an isodense nodule with partially indistinct margin in the right breast, showing the abnormality score 75% on artificial intelligence. Ultrasonography revealed an oval hypoechoic nodule with microlobulated margin, echogenic halo, increased blood flow, and soft elasticity. After core needle biopsy and excision, nodular fasciitis was diagnosed. Although nodular fasciitis of the breast is rare, it may mimic malignancy; therefore, it should be considered as a differential diagnosis to prevent unnecessary intervention.

Nodular fasciitis is a benign proliferative lesion of the fibroblasts and/or myofibroblasts, generally detected in the soft tissue of the upper extremities. It has also been reported in the lower extremities, head, and neck, and rarely in the breast. Its rarity and nonspecific clinical and radiological features resemble those of malignant tumors of the breast and make the differential diagnosis and management difficult. Herein, we present a rare case of nodular fasciitis of the breast, which was initially suspected to be a phyllodes tumor.

Nodular fasciitis (NF) is a benign myofibroblastic proliferation that grows very rapidly, mimicking a sarcoma on imaging. It is treated by local excision, and recurrence has been reported in only a few cases, even when excised incompletely. The most prevalent diagnoses of temporomandibular joint(TMJ) masses include synovial chondromatosis, pigmented villonodular synovitis, and sarcomas. Cases of NF in the TMJ are extremely rare, and only 3 cases have been reported to date. Due to its destructive features and rarity, NF has often been misdiagnosed as a more aggressive lesion, which could expose patients to unnecessary and invasive treatment approaches beyond repair. This report presents a case of NF in the TMJ, focusing on various imaging features, along with a literature review aiming to determine the hallmark features of NF in the TMJ and highlight the diagnostic challenges.

A 40-year-old woman was admitted to the hospital due to a palpable tumor on an anterior chest wall. The tumor was diagnosed with a nodular fasciitis. It is a rare benign soft-tissue tumor which has a characteristic referred to as proliferation of fibroblast, and a surgical removal is the best effective treatment. Therefore, we report this case with documents and considerations after the surgical removal.

Purpose: Cranial fasciitis is a rare type of benign tumor that occurs mostly in children younger than 6 years. It arises from the deep fascia, periosteum, or fibromembranous layer that covers fontanelles. The etiology is unknown, although prior trauma has been postulated to be an underlying cause. There is a 2:1 male predominance. Despite its rapid growth, this tumor has a benign clinical course and can be cured by total excision. Methods: A 16-year-old male presented with a 3 cm-sized palpable mass in the left lateral eyebrow region that he first noticed 4 months before presentation. The mass had grown rapidly since it was first noticed. Preoperative brain computed tomography showed a well-demarcated mass approximately 3 cm in size extending from the subcutaneous layer to the periosteum. Preoperatively, the presumed diagnosis was a dermoid cyst. An operation was performed with the patient under general anesthesia. The subcutaneous mass was completely excised by periosteal dissection. Results: Histological diagnosis revealed the presence of cranial fasciitis. After 20 months of follow-up, there have been neither complications nor evidence of local recurrence besed on clinical examination. Conclusion: Although cranial fasciitis is quite rare, it should be considered in the differential diagnosis for lytic skull lesions in patient whose clinical presentation suggests this possibility. This condition could be occasionally mistaken for malignant or locally aggressive lesions. To prevent local recurrence, curettage of the underlying bone is recommended for patients with bone involvement.
