It is a reactive lesion composed of fibroblasts/myofibroblasts and most commonly found in extremities and trunk. NF has been described in the head and neck region in 10-20% of cases. Many pathologists do not consider NF in the differential diagnosis of soft tissue masses arising in the Head neck region. NF that occurs in otherwise healthy individuals usually presents with a history of rapid growth, and is commonly found in the upper extremities and on the chest and trunk. The importance of otolaryngologists being aware of the existence of this entity in this area of the body is stressed. It has a confirmed perfectly benign clinical course, and simple excision, as tissue-sparing as possible, is the treatment of choice. A case of NF over the neck in a 05-year-old female not associated with trauma who presented with a localized mass over her left neck is presented. </font><br> <font face="Verdana" size="2" color="#000080"><b>Key Words:</b> Benign; Neck; Nodular fasciitis; Paediatric.</font></td> </tr> <tr> <td valign="top"><p align="justify" class="title"><b>Introduction</b></p> <P align="justify" class="verd">Nodular fasciitis (NF), a benign proliferation of fibroblasts, commonly presents as a solitary, well-circumscribed, rapidly growing soft tissue mass.

NF is located in the head and neck only in 10% to 20% of cases Although benign, it can often be confused with a more malignant process and therefore must be properly diagnosed histologically. The cause of NF is unknown but an association with trauma may be present. Treatment is most commonly by local surgical excision, and recurrence is rare. </p> <span class="title"><strong>Case Report</strong></span> <p align="justify" class="verd">A 5 years old female child referred by other hospital presented with 2 years history of a progressively growing swelling over the left side of neck.

NF is a benign lesion but can often be confused with myofibromatosis or a sarcoma due to its rapid rate of growth, rich cellularity and mitotic activity.<sup>3</sup></p> <p align="justify" class="verd">Nodular fasciitis is common in young adults (between 25 and 35 yrs) and less frequently in children. NF can occur almost anywhere on the body; however, the most common location in the adult population is in the upper extremities (39% to 54%), especially on the volar aspect of the elbow. They can also be found on the trunk (15% to 20%) and the lower extremities (16% to 18%). NF is located in the head and neck only in 7% to 20% of cases.<sup>3</sup> In children, however, the head and neck region is the most common site. Approximately 10% of all lesions are found in children.<sup>4</sup> In addition, it is more commonly found in those in the third through fifth decades of life; only 10% to 20% are found in those over 50 years of age.<sup>5</sup></p> <p align="justify" class="verd">Exact cause of the lesion is not known but it is considered to be a self limiting reactive process rather than a true neoplasm.<sup>6,7 </sup>The cause is unknown but has often been linked to local injury or trauma. In the literature, 10% to 15% of cases have been found to be associated with trauma,<sup>2,5,8</sup> but this was not the case in our patient. Although most commonly located on the extremities and then the trunk, it is estimated that the head and neck region represents only 10 to 20%. The majority of cases arise in the soft tissue, i.e. fascia, muscle, or subcutaneous tissue. Interestingly, cases in the head and neck region often involve dermal tissue. It presents as a solitary painless, rapidly growing nodule over several weeks' duration. It usually ranges from 1 cm to 3 cm in greatest diameter.</p> <p align="justify" class="verd">In adults, these are commonly located in the upper extremities (flexor surface of the forearm) and the trunk (chest wall and back). In infants and children, nodular fasciitis is present in the head and neck region.The lesion consists of nodular, nonencapsulated mass usually less than 3cm in diameter.The cut surface may show firm and grey white or soft and gelatinous areas.<sup>6</sup></p> <p align="justify" class="verd">The subtypes are: </p> <div align="justify"> <ul> <li class="verd">Fascial type- Poorly circumscribed lesion , extends along the superficial fascia and interlobular septa of subcutaneous fat .</li> <li class="verd">Subcutaneous type- Well circumscribed lesion, extends into the subcutis.</li> <li class="verd">Intramuscular type- Well circumscribed lesion, grows into the skeletal muscle.</li> <li class="verd">Intradermal type - Lesion present in the dermis (intradermal fasciitis)</li></ul></div> <p align="justify" class="verd">The condition is self-limited, and proper diagnosis is essential to avoid unnecessary aggressive treatment. Diagnosis is often a challenge because it may be confused with a malignant tumor due to its aggressive clinical behavior and histological features. Immunohistochemical staining can be a useful tool to aid in the diagnosis.<sup>7,9</sup></p> <p align="justify" class="verd">Proper diagnosis requires histological confirmation. NF typically shows well-circumscribed, unencapsulated nodules composed of spindle cells. Microscopically early cases of Nodular fasciitis display zonation effect with maturation from the centre (hypocellular or hyalinized) to the periphery (hypercellular with inflammatory cell, blood vessels). In between, the loose myxoid area is populated by non-pleomorphic myofibroblasts loosely arranged with a tissue culture look. The backround stroma shows variable myxoid change. The proliferating cells are of fibroblastic and myofibroblastic type. The high cellularity and mitotic activity can mimic sarcoma. It is especially problematic in the pediatric population in which nodular fasciitis is not commonly encountered while mesenchymal malignancies of the head and neck are of fundamental concern. The alternative possibilities are leiomyosarcoma, fibrosarcoma and even sarcomatoid carcinoma. The rapid clinical onset, presence of stromal chronic inflammation and lack of cytological atypia are all critical features that help identify the lesion as benign.<sup>7,10</sup> On immunohistochemistry NF demonstrates focal smooth muscle and muscle specific actin and calponin, but not usually desmin, h-caldesmon or CD34. CD68 may be positive in some cases. The following features rule out malignant tumour: i) Absence of atypia ii) Absence of atypical mitotic figures iii) Small size iv) Short history v) Superficial location in young adults.<sup>6</sup></p> <p align="justify" class="verd">Local excision is the treatment generally advocated for nodular fasciitis but intra-lesional steroids have been tried with varied success.<sup>11</sup> Spontaneous regression of these lesions is also known to occur.<sup>12</sup> Owing to its ominous presentation nodular fasciitis has a tendency to be over-treated. Generally, if recurrence does occur after excision, incomplete resection should be suspected but a malignant process should be reconsidered.<sup>13,14</sup></p> <p class="title"><strong>Conclusion</strong></p> <p align="justify" class="verd">NF is an uncommon benign proliferation of fibrous tissue rarely seen in neck. It is important to distinguish it from a malignant process because NF can be successfully treated with complete local excision.</p> <p align="justify" class="title"><strong>References</strong></p> <ol> <li class="verd">Konwaler BE, Keasbey L, Kaplan L.
