Several inflammatory processes can cause nodules or swelling in the neck. A complete physical examination and, usually, laboratory testing are required to establish the diagnosis. Common infections include cervical lymphadenitis and tuberculous lymphadenitis, cat-scratch disease, infection in the neck spaces, infectious mononucleosis, and syphilis. Primary or metastatic cancer may also be the cause. Cervical metastasis often presents as a neck mass. Although a primary tumor may not be found immediately when a neck mass is being evaluated, one is often discovered later. Other types of malignancy that may be present are histiocytic lymphoma, Hodgkin's disease, rhabdomyosarcoma, thyroid cancer, and a salivary (most often parotid) gland tumor. Symptomatic treatment is sometimes adequate for infectious disease, but administration of antituberculous drugs or antibiotics may also be necessary. Incision and drainage are required for some nodes and abscesses. For neck masses caused by neoplasms, fine-needle aspiration cytology or biopsy is performed. Depending on the diagnosis, treatment consists of dissection, radiation therapy, and/or chemotherapy.

Neck masses in children usually fall into one of three categories: developmental, inflammatory/reactive, or neoplastic. Common congenital developmental masses in the neck include thyroglossal duct cysts, branchial cleft cysts, dermoid cysts, vascular malformations, and hemangiomas. Inflammatory neck masses can be the result of reactive lymphadenopathy, infectious lymphadenitis (viral, staphylococcal, and mycobacterial infections; cat-scratch disease), or Kawasaki disease. Common benign neoplastic lesions include pilomatrixomas, lipomas, fibromas, neurofibromas, and salivary gland tumors. Although rare in children, malignant lesions occurring in the neck include lymphoma, rhabdomyosarcoma, thyroid carcinoma, and metastatic nasopharyngeal carcinoma. Workup for a neck mass may include a complete blood count; purified protein derivative test for tuberculosis; and measurement of titers for Epstein-Barr virus, cat-scratch disease, cytomegalovirus, human immunodeficiency virus, and toxoplasmosis if the history raises suspicion for any of these conditions. Ultrasonography is the preferred imaging study for a developmental or palpable mass. Computed tomography with intravenous contrast media is recommended for evaluating a malignancy or a suspected retropharyngeal or deep neck abscess. Congenital neck masses are excised to prevent potential growth and secondary infection of the lesion. Antibiotic therapy for suspected bacterial lymphadenitis should target Staphylococcus aureus and group A streptococcus. Lack of response to initial antibiotics should prompt consideration of intravenous antibiotic therapy, referral for possible incision and drainage, or further workup. If malignancy is suspected (accompanying type B symptoms; hard, firm, or rubbery consistency; fixed mass; supraclavicular mass; lymph node larger than 2 cm in diameter; persistent enlargement for more than two weeks; no decrease in size after four to six weeks; absence of inflammation; ulceration; failure to respond to antibiotic therapy; or a thyroid mass), the patient should be referred to a head and neck surgeon for urgent evaluation and possible biopsy.

Rhabdomyosarcoma is a highly aggressive malignant cancer that arises from skeletal muscle progenitor cells and is the third most common solid tumour in children. Despite significant advances, rhabdomyosarcoma still presents a therapeutic challenge, and while targeted therapy has shown promise, there are limited options because the molecular drivers of rhabdomyosarcoma are poorly understood. We previously reported that the T-box transcription factor 3 (TBX3), which has been identified as a druggable target in many cancers, is overexpressed in rhabdomyosarcoma patient samples and cell lines. To identify new molecular therapeutic targets to treat rhabdomyosarcoma, this study investigates the potential oncogenic role(s) for TBX3 and the factors responsible for upregulating it in this cancer. To this end, rhabdomyosarcoma cell culture models in which TBX3 was either stably knocked down or overexpressed were established and the impact on key hallmarks of cancer were examined using growth curves, soft agar and scratch motility assays, as well as tumour-forming ability in nude mice. Our data show that TBX3 promotes substrate-dependent and -independent proliferation, migration and tumour formation. We further reveal that TBX3 is upregulated by c-Myc transcriptionally and AKT1 post-translationally. This study identifies c-Myc/AKT1/TBX3 as an important axis that could be targeted for the treatment of rhabdomyosarcoma.
