Cytological Diagnosis and Misdiagnosis of Nodular Fasciiti

  1. Nodular fasciitis (NF) is a rapidly growing, self-limiting, subcutaneous nodular cytologic exuberant fibroblastic/myofibroblastic proliferation prone to cytological misdiagnosis
  2. Nodular fasciitis (NF) is the commonest of the benign pseudosarcomatous lesions. It presents as a rapidly enlarging, often painful or tender subcutaneous nodule, most often affecting young adults and showing a predilection for the upper limb, especially the forearm
  3. Background and Objective: Nodular fasciitis (NF) is a self-limiting, transient neo-plasm composed of fibroblasts and myofibroblasts. Since it regresses spontaneously, diagnosis by fine needle aspiration (FNA) cytology plays a major role in its manage-ment

We report a case of nodular fasciitis (NF) of the breast, which was cytologically diagnosed as a spindle cell proliferation with undetermined malignant potential. Owing to small size of the lesion (5.9 × 3.7 × 4.1 mm), only fine needle aspiration (FNA) cytology was performed under ultrasound guidance Nodular fasciitis Comment: This is spindle stellate cell neoplasm arranged in short bundles and fascicles. The nuclei are ovoid and monomorphic, with occasional mitotic activity. The stroma is variably myxoid to collagenous, with scattered lymphocytes and extravasated erythrocytes Nodular fasciitis is a rapidly growing lesion of benignfibroblastic tissue that most commonly is diagnosed in youngand middle aged adults, with a peak incidence in the thirdand fourth decades of life.

Data Collectio Nodular fasciitis (NF) is a benign, self-limited, fibroblastic/myofibroblastic proliferation that is diagnostically challenging, often mimicking a malignant process due to its rapid growth clinically and its high cellularity, mitotic activity, and variable/nonspecific cytomorphologic findings

Cytological diagnosis and misdiagnosis of nodular fasciiti

  1. Nodular fasciitis may occasionally involve muscle LGFS may contain areas indistinguishable from nodular fasciitis; both are composed of bland cells Although fibroma of tendon sheath is typically sclerotic and nodular fasciitis is typically not, there is sufficient variation in patterns to cause overlap
  2. Nodular Fasciitis • Relatively common fibrous proliferation typically occurring in subcutaneous tissue • Head and neck (including the salivary gland) is among the most common Cytology 5th Edition. 2012. Salivary Gland Lesions . FNA and Salivary Gland Lesions •Cytologic diagnoses of malignant tumors were confirmed histologically in 93
  3. Cytology Accurate cytologic diagnosis of nodular fasciitis is possible with knowledge of the fine needle aspiration cytology (FNAC) features along with clinical correlation, thus avoiding unnecessary surgical intervention. Sampling error is a possible limitation of this diagnostic technique
  4. Given its rarity, varied histological presentation and often pseudosarcomatous appearance, nodular fasciitis is frequently misdiagnosed on pre-operative, intra-operative and final analyses

Histology of nodular fasciitis Low power examination of nodular fasciitis shows a well- circumscribed discrete mass in the subcutaneous adipose tissue (figure 1). Dermal and intravascular forms have also been described

A case of nodular fasciitis involving the thumb of a 4-year-old male child is presented. Main significance lies in clinical and pathological recognition of the lesion to avoid over-treatment. Nodular fasciitis remains a difficult diagnosis by fine needle aspiration cytology, particularly when it occurs in locations such as the hand Nodular fasciitis of the breast is rarely diagnosed on cytology alone and a histological diagnosis is usually required for a definitive diagnosis. However, in this case, the lesion spontaneously resolved prior to core biopsy or diagnostic open biopsy Papillary thyroid carcinoma with nodular fasciitis-like stroma is one of the rare variants of papillary thyroid carcinoma. The problems posed by the exuberant nodular fasciitis-like stroma, which obscures the neoplastic nature of the tumor, are recognized in surgical pathology but have received little attention in the cytopathology literature

Nodular fasciitis is a benign tumour that arises from the proliferation of fibroblasts and myofibroblasts. It most commonly arises from the extremities and trunk and rarely from the head and neck region [].Despite its benign nature, it characteristically exhibits rapid growth, which is demonstrated on histology or cytology as increased mitotic activity Nodular fasciitis (NF) is a benign reactive or inflammatory condition of mesenchymal fibroblasts. Rapid growth and histological features make nodular fasciitis a mimicker of malignancies such as sarcomas, however, nodular fasciitis is a benign lesion and does not metastasize Nodular fasciitis of parotid region: A pitfall in the diagnosis of pleomorphic adenomas on fine‐needle aspiration cytology Reda S.

Ultrasound guided fine needle aspiration (FNA) of the solid mass was performed. Cytology was reported as atypical spindle cell neoplasm and the patient was referred to a breast surgeon at a tertiary institution for a definitive diagnosis and further management Cytopathology, often called cytology, is the study of pathologic changes in cells.. Specimen types include exfoliated cervical cytology (Pap tests), urine, body cavity fluids (pleural, pericardial, and peritoneal), cerebrospinal fluid, and fine needle aspirations from any body site, among others (see detail articles section).These are often collected by minimally invasive means In addition, once the diagnosis of nodular fasciitis (NF) is made, even though known as benign, the most frequent treatment for this condition is still surgery. What we intend to show is that fine needle aspiration cytology (FNAC) is a minimally invasive technique that can make the diagnosis and offer a watchful waiting strategy

Nodular fasciitis of parotid region: a pitfall in the diagnosis of pleomorphic adenomas on fine-needle aspiration cytology. Saad RS , Takei H , Lipscomb J , Ruiz B Diagn Cytopathol , 33(3):191-194, 01 Sep 200 Nodular fasciitis is rarely diagnosed by fine needle aspiration cytology or core needle biopsy, and it usually requires excisional biopsy for histologic confirmation. While authors have reported the proliferation of neoplastic spindle cells was suspected, no definitive diagnosis was obtained with aspiration cytology [ 8 ] Introduction. Nodular fasciitis, described for the first time in 1955 by Konwaler et al. [], is a benign disorder characterized by a pseudoneoplastic proliferation of myofibroblasts.Generally, it is detected in the soft tissue of the extremities, of the trunk and the neck, although involvement of muscles, fasciae and parenchymatous organs was described, and virtually all parts of the body can.

Nodular Fasciitis: A Frequent Diagnostic Pitfall on Fine

Cellular stroma with new bone, atypia and mitotic figures, rarely cartilage; zonation often present, although zones may be poorly demarcated Early lesions (3 weeks): inner cellular zone resembling nodular fasciitis with short fascicles or haphazard fibroblasts that are uniform with faint eosinophilic cytoplasm, tapering processes, vesicular or finely granular nuclei and variable nucleoli. Nowadays, histopathology and immunohistochemistry play a pivotal role in diagnosis as fine-needle aspiration cytology (FNAC) can be correctly diagnosed only if the cytologist is aware of its clinical and cytologic features. Following a short Literature review, the authors report a rare case of maxillary nodular fasciitis in an 85-year-old.

Nodular fasciitis is a benign reactive proliferation that usually involves the deep fascia. The rapidly growing, the abundant cellularity, and the mitotic activity noted on histology can simulate an aggressive entity, such as sarcoma. We report an uncommon case of nodular fasciitis involved the chest wall of a thirteen boy and its management, emphasizing the need to consider this lesion in the. Nodular fasciitis, also called pseudosarcomatous fasciitis, proliferative fasciitis or infiltrative fasciitis, is a rare, noncancerous tumor. It appears in soft tissue anywhere in the body. Nodular occurs mostly in adults aged between 20 to 40, and it affects males and females with equal frequency Nodular fasciitis (NF) is a rapidly growing benign lesion rarely reported in the parotid gland. It shares cytological features with other benign and malignant parotid neoplasms and may be difficult to diagnose based on fine needle aspiration cytology alone.

However, it has rarely been reported in the breast of an elderly woman. Our patient was an 88-year-old Asian woman who had noticed a mass in her right breast for 1 month before presentation to our hospital. The mass was elastic-hard and 20 mm in size

Background: Nodular fasciitis (NF) is a clonal, self-limited proliferation that has only rarely been described in the parotid gland. Because of its potential to mimic benign and malignant parotid neoplasms clinically, radiographically, and cytomorphologically, NF is often managed with unnecessary surgery, which is associated with a risk for significant surgical complications Objectives: Nodular fasciitis (NF) is a self-limited, mass-forming, fibrous proliferation that can occur in the head and neck and may mimic malignancy. Fine-needle aspiration biopsy (FNAB) is a minimally invasive, rapid, accurate method of obtaining diagnostic material from head and neck masses In 24 case reports of nodular fasciitis of the breast, four underwent FNA.1 -791730 A specific diagnosis of nodular fasci-itis was not made in any of these. Six underwent subsequent core biopsy with a definitive diagnosis of nodular fasciitis in three based on a combination of histological findings and spon-taneous regression of the lesion

  1. Nodular fasciitis of the breast is a rare benign pathology of soft tissue that is a consequence of fibroblastic hyperplasia within breast. It can mimic breast cancer clinically, radiologically, and histopathologically.A-43 year-old female with a painless mass within upper-lateral quadrant of her left breast complained of rapid and progressive growth during previous few days
  2. Nodular fasciitis is a benign proliferative lesion that is usually found in the soft tissue of the upper extremity and trunk in young to middle-aged persons. It has rarely been described in the breast. A 35-year-old woman had noticed a mass in her left breast. It was elastic-hard, 13 mm in size, and located mainly in the upper inner quadrant of the left breast
  3. Pseudosarcomatous lesions are benign neoplasms of the musculoskeletal system that are likely to be misdiagnosed as malignant, based on clinical and histologic features. These include soft‐tissue tumors considered reactive or reparative lesions such as nodular fasciitis and myositis ossificans. Also included in the pseudosarcoma category are benign neoplasms which show.
  4. Firm, painless, nodular swelling, usually in the bulbar conjunctiva at the limbus. If extending into the peripheral cornea, there is edema and vascularization. Since gross findings are diagnostic and disease responds to anti-inflammatories histopathology is performed only in atypical lesions. May appear as a diffuse, subconjunctival thickening
  5. Fine-needle aspiration cytology poses a considerable element of uncertainty in the diagnosis of nodular fasciitis. Its features of nodular fasciitis may mimic that of pleomorphic adenoma due to the presence in both of spindle and plasmacytoid cells, clumping of inter-cellular stromal material, and myxoid background

Nodular fasciitis (subcutaneous pseudosarcomatous

Nodular fasciitis (NF), very uncommon in the parotid gland, is a benign myofibroblastic proliferation that may be mistaken for other neoplastic proliferations. The mass-like clinical presentation and histologic features result in frequent misclassification, resulting in inappropriate clinical management. There are only a few reported cases in the English literature. Cases within the files of. Nodular fasciitis has propensity to occur in children and young adults on head and neck, trunk and upper extremities, but it is extremely rare to occur in the auricular region. Its etiology was thought to be reactive, but it is now found to have USP6-MYH9 fusion gene in most cases, thus favoring a neoplastic process Nodular fasciitis is most common in the third decade, but occurs at all ages. Males and females are equally affected. It usually presents as a rapidly growing soft tissue mass, somewhat tender and fixed to the subjacent structures, but with freely moveable overlying skin

Nodular fasciitis is a self-limiting, pseudosarcomatous lesion composed of fibroblasts and myofibroblasts. 1 Although arising most often within the extremities, NF can often arise within the head and neck. Nodular fasciitis arises within fascia or subcutaneous tissue but can also occur within muscle or organ parenchyma, such as the parotid gland Abstract: Nodular fasciitis is a relatively rare, benign and proliferative lesion that is not typically found in the retroperitoneal (RP) space and has not been previously reported as a cause of gastric outlet obstruction (GOO). GOOs are frequently associated with malignancies, however, benign etiologies should be considered as well. We report the first case of GOO secondary to nodular.
