An 86-year-old woman was referred to the otolaryngology clinic for a 1-year history of a painless, slow-growing neck mass. Physical examination showed a fixed, immobile right level II neck mass with normal vocal cord movement. MRI demonstrated a lobulated mass laterally displacing the carotid vessels, consistent with a schwannoma. Despite the pathognomonic radiographic findings for schwannoma, core needle biopsy of the mass was consistent with intramuscular myxoma (IM), which rarely presents in the head and neck region. After multiple years of slow growth with bulging into the pharynx, the patient ultimately underwent surgery to reduce the risk of airway compromise. The location of this IM together with its unusual imaging appearance is a unique finding in the head and neck and adds to the differential diagnoses for neck masses displacing the carotid sheath.

Hemangiomas of the head and neck region comprise about 60 to 70% of all benign tumors. Intramuscular hemangioma is a rare, slow-growing, angiomatous tumor. We report a rare case of an Intramuscular Hemangioma of Right sternocleidomastoid muscle in a six years old girl presenting for four years and with extensive involvement necessitating excision. Microscopic excision reduces the risk of recurrence.

Head And Neck Masses

Background. Intramuscular hemangioma (IMH) is a distinctive type of hemangioma occurring within skeletal muscle. Most IMH are located in the lower extremity, particularly in the muscles of the thigh. When present in the head and neck region, the masseter and trapezius muscle are the most frequently involved sites. Case report. We reported a case of unusual localization of the head and neck IMH occurring within the retropharyngeal space (RPS). To our knowledge, this is the second such case reported in the English literature. The tumor presented as a left-sided neck mass with bulging of the posterior and left lateral oropharyngeal wall on indirect laryngoscopy. Computed tomography (CT) scan revealed an ill-defined mass in the RPS at the oropharyngeal level. The lesion was excised via a transoral approach and microscopically diagnosed as IMH, the complex malformation subtype. Although surgical margins were positive, no recurrence of the tumor was noted in the 17-month follow-up. Conclusion. Intramuscular hemangioma should be considered in the differential diagnosis of deep head and neck masses. The knowledge of the infiltrative nature and recurrence rate of an IMH is useful for appropriate management. .

Rare Malignancy

Leiomyosarcoma (LMS) of the trachea is an extremely rare malignancy with only a few reported cases in English literature. As such the diagnosis can be frequently missed or delayed. We present a case of a 69-year-old male who underwent tracheostomy for airway obstruction secondary to glottic squamous cell carcinoma and treated definitely with radiation therapy. Subsequently, the patient developed LMS of the tracheostomy site. The case further details multiple risk factors that could contribute to development of LMS including radiation exposure, prior malignancy, and chronic inflammation. These risk factors have been well established for LMS in other sites but less so in the head and neck region, which is the subject of our discussion. We also review the current guidelines for head and neck as well as limb sarcomas and discussed role of surgery or radiation and their accompanying challenges in management of this rare malignancy.

Context.—Myeloid sarcoma of the head and neck region can pose diagnostic challenges because of the low frequency of myeloid sarcoma and the potential for tumors of almost any lineage to occur in the head and neck. Objective.—To study the clinicopathologic and immunohistochemical characteristics of myeloid sarcoma in the head and neck region and to review the differential diagnosis. Design.—We searched for cases of myeloid sarcoma involving the head and neck region for a 24-year period at our institution. The medical records and pathology slides were reviewed. Additional immunohistochemical stains were performed. Results.—We identified 17 patients, age 17 to 85 years. Most tumors involved the oral cavity. Myeloid sarcoma was the initial diagnosis in 9 patients (53%); the remaining 8 patients (47%) had a history of bone marrow disease. Immunohistochemical analysis using antibodies specific for lysozyme, CD43, and CD68 were highly sensitive for diagnosis but were not specific. By contrast, assessment for myeloperoxidase in this study was less sensitive but more specific. We also used antibodies specific for CD11c and CD33 in a subset of cases, and these reagents seem helpful as well. Conclusions.—The clinical presentation of myeloid sarcoma involving the head and neck, particularly the mouth, is often nonspecific, and a high degree of suspicion for the possibility of myeloid sarcoma is needed. Immunohistochemistry is very helpful for establishing the diagnosis.

<p class="abstract">Schwannoma are slow growing tumours, which can arise from any peripheral nerve. 10% of schwannomas that occur in the head and neck region mostly originate from the vagus or sympathetic nervous system. Extracranial schwannomas in the head and neck region are rare neoplasm. Intraoral schwannoma are only 1% of the all head and neck tumours. Diagnosis is established by imaging studies such as magnetic resonance imaging or computed tomography, while FNAC is used to rule out other conditions. We report a rare case of lingual schwannomas generally present as a painless lump schwannoma of the tongue in a 27-year-old male complaining of asymptomatic swelling over a posterolateral surface of the tongue, treated by complete surgical excision. The diagnosis was established on the basis of clinical, histopathological, and immunohistochemical examination. We report a rare case of schwannoma over the posterolateral surface of tongue. Prognosis is good for the patient when this condition is correctly diagnosed as the condition rarely recurs after complete resection.</p>

Nerve Of Origin

Introduction. Schwannomas are tumors of neurogenic origin, that arise from Schwann cells which surround peripheral, cranial and autonomic nerves. Schwannomas account for only 5% of all benign soft tissue tumors, and 25-45% of extracranial schwannomas are present in the head and neck region. They are usually classified according to the nerve of origin and the site within the head and neck. Case report. We presented extremely rare extracranial localizations of schwannomas and discussed about diagnosis and management of these tumors. Conclusion. Schwannomas are slow-growing tumors and late symptoms appearance may cause a delay in diagnosis and treatment of patients with these tumors. An appropriate diagnostic protocol is indispensable tool in performing a differential diagnosis of malignant from benign lesions. Choice of surgical approach depends on schwannomas localization.

Cancer metastasis to the oral and maxillofacial region is uncommon, and metastasis to the mandibular condyle is considered rare. We present a case of a 56-year-old woman with a history of invasive ductal cell carcinoma of the right breast, 10 years in remission, presenting with a 6-month history of symptoms typical of temporomandibular joint (TMJ) dysfunction. Imaging revealed an osteolytic lesion of her right TMJ and subsequent open biopsy confirmed the diagnosis of metastatic breast cancer. Despite the rarity of metastatic cancer to the head and neck region, it is still important for clinicians from both medical and dental backgrounds to consider this differential diagnosis, particularly in patients with a history of hormonal positive subtype of breast cancer. Given that bony metastasis can manifest even 10 years after initial diagnosis, surveillance which includes examination of the head and neck region is important, and may include routine plain-film imaging surveillance with an orthopantomogram (OPG).

Further Development

Embryology and development have been covered after the main anatomical descriptions in the previous sections, but it is going to precede them in this section. The reason for this departure is that the embryonic development of the head and neck explains much of the mature anatomy which can seem illogical without its developmental history. The development of the head, face, and neck is an area of embryology where significant strides in our understanding have been made in the last few years. The development of the head is intimately related to the development of the brain outlined in Chapter 19 and its effects on shaping the head will be described in Chapters 32 and 33. The major thrust of this chapter is the description of the formation of structures called the pharyngeal (or branchial) arches and the fate of the tissues that contribute to them. All four embryonic germ layers contribute to the pharyngeal arches and their derivatives, hence to further development of the head and neck. Figure 21.1 is a cross section through the neck region of a 3-week old embryo after neurulation and folding described in Chapter 8. It shows the structures and tissues that contribute to the formation of the head and neck: • The neural tube situated posteriorly and the ectomesenchymal neural crest cells that arise as the tube closes; • The paraxial mesoderm anterolateral to the neural tube; • The endodermal foregut tube anteriorly; • The investing layer of ectoderm. The development of all these tissues is intimately interrelated. The pharyngeal arches are very ancient structures in the evolutionary history of vertebrates. The arches and their individual components have undergone many modifications during their long history. In ancestral aquatic vertebrates, as in modern fishes, water was drawn in through the mouth and expelled through a series of gill slits (or branchiae, hence the term ‘branchial arch’) in the sides of the pharynx. Oxygen was extracted as the water was passed over a gill apparatus supported by a branchial arch skeleton moved by branchial muscles controlled by branchial nerves. Although ventilation and respiration is now a function of the lungs in land vertebrates, the pharyngeal arches persist during vertebrate development.

Inflammatory Pseudotumors

Inflammatory pseudotumor (IP) is an uncommon idiopathic lesion that often imitates malignancy clinically and radiologically. Inflammatory pseudotumors have been found to occur in various sites but rarely in the head and neck. The histopathology, imaging, and treatment of three unique cases of head and neck inflammatory pseudotumors are described in this case series. Patients in Cases 1 and 2 presented with right level II neck mass and left parotid tail mass, respectively. The patient in Case 3 presented with otalgia, jaw pain and trismus, and a left parapharyngeal space mass. The tumors in Cases 1 and 3 significantly decreased in size with tapered courses of oral corticosteroids. The tumor in Case 2 was surgically excised without disease recurrence. Malignancy must be ruled out with incisional or excisional biopsy. Treatment includes surgical excision, oral corticosteroids, or both. The literature shows that radiotherapy and small-molecule inhibitors may be promising alternatives.

Rare Diagnosis

Schwannomas/ neurilemmomas are benign tumors of nerve sheath arising from Schwann cells that form myelin sheath around peripheral nerves. They are usually solitary, slow growing and encapsulated lesions. Head and neck are the common sites. We report a case of a 38 years old Nepalese female who had presented with a solitary asymptomatic, slow growing nodule on the left side of the chin for the last three years. Dermoscopy of the lesion revealed arborizing vessels with brownish pigmentation overlying a whitish to pinkish background. Complete excision of the lesion was performed. Histopathological evaluation of the lesion revealed schwannoma. Though schwannomas are a rare diagnosis, they should be considered as a differential diagnosis of any unilateral, asymptomatic, slow growing nodule in the head and neck region. Dermoscopy is a useful tool which helps to differentiate schwannoma from other lesions. Histopathology is the gold standard for diagnosis and the treatment of choice is surgical excision.
