“…Most lesions are solitary and occur in adults 20–50 years of age and have equal incidence among sexes [6]. Reported lesions are usually less than 3–4 cm in diameter and rarely increase in size to more than 4 cm in diameter as occurred in the present case [7]. Bernstein et al reported that lesions of NF rarely exceed 4 cm and 71% were smaller than 2 cm in their series comprising 134 cases [8].…”

“…NF lesions are classified into three subtypes according to the anatomical location: subcutaneous, fascial (intermuscular), and intramuscular. The subcutaneous form is most common, followed by the fascial form, with the intramuscular form being the least common [7]. Histologically, NF is usually a well-circumscribed yet nonencapsulated mass composed of fibroblastic and myofibroblastic proliferation arranged in short fascicles and untidy bundles.…”

Nodular fasciitis (NF) is a benign reactive proliferation of myofibroblasts that predominantly occurs subcutaneously. Commonly, it presents as a rapidly growing swelling in 4-8 weeks. NF mostly occurs in adults aged 20-50 years and usually has a diameter<3‐4 cm. Giant NF with a diameter>4 cm is rare. Owing to its rapidly growing nature, a precise clinical diagnosis is difficult; it is frequently misdiagnosed as an aggressive or malignant tumor. Herein, we present the case of a 15-year-old male who presented with a large protruding mass on the anterior chest wall. The tumor appeared clinically malignant as it was protruding and had doubled in size within a few weeks, reaching approximately 8×6 cm. Furthermore, the tumor separated and fell off spontaneously due to its large size. As the remaining tumor continued to grow rapidly, surgery was performed. Following wide tumor resection, no recurrence, metastases, or other complications were noted 1 year postsurgery. NF was diagnosed after pathological evaluation, including immunohistochemical analysis, molecular genetic testing, and cytogenetic testing via fluorescence in situ hybridization analysis. Knowledge of the atypical clinical course and a combination of histopathological examinations are necessary to accurately diagnose NF.

“…It sometimes shows spontaneous regression [6] and recurrence is rare, even after incomplete excision [2], with no reports of malignant transformation. These lesions may show atypia and mitoses, making nodular fasciitis difficult to distinguish from sarcoma [5,[7], [8], [9]]. In fact, Plaza et al [10] reported that two thirds of their cases were misdiagnosed as sarcoma.…”

“…Rarely involved sites include breast, intra-articular, nerve sheaths, and retroperitoneum. 8 Fine needle aspiration cytology (FNAC) can be done in the initial evaluation though the diagnosis is quite challenging. The relatively small amount of tissue obtained is often insufficient for a definitive panel of special stains, and thus surgical excision with histological evaluation is recommended.…”

Nodular fasciitis is defined as a benign and reactive fibroblastic growth extending from the superficial fascia into the subcutaneous tissue or muscle. It is a rare benign neoplasm most commonly afflicting the soft tissues of upper extremity followed by trunk, head, and neck. It accounts for 0.025% of all pathologic diagnosis. We report a case of a swelling over the right scapula which on cytology examination was diagnosed as a benign spindle cell lesion. It was subsequently confirmed to be an intramuscular nodular fasciitis on histopathological examination.
