Purpose: Spindle cell lipoma(SCL) is an uncommon subcutaneous soft tissue neoplasm that arises in the shoulder and posterior neck of older male patients. The imaging appearance of SCL is not pathognomonic and can display some features overlapping with liposarcoma. We report a case of SCL on the posterior neck. Method: The patient is a 50 - year - old man with a slowly enlarging subcutaneous mass on the right side of posterior neck. Computed tomographic imaging revealed a 7.0 cm sized, well - circumscribed, heterogenous and fatty mass with enhanced solid components. Whole body Fluorine - 18 Fluorodeoxyglucose Positron emission tomogram(FDG PET-CT) showed little increase of FDG uptake on the right posterior neck and there was no distant metastasis. Results: The mass was surgically removed. The resection margin was free of tumor on frozen biopsy. Histopathologic examination indicated spindle cell lipoma consisting of a mixture of mature adipocytes and uniform spindle cells within a matrix of mucinous material. Conclusion: Although CT image of solidtary mass in posterior neck is similar with the one of liposarcoma, we should consider that it may be a spindle cell lipoma if PET-CT and other systemic studies reveal no distant metastasis. And we should perform fine needle aspiration to differentiate SCL from malignant lesions.

Purpose: The pathophysiology of congenital muscular torticollis (CMT) is that the sternoclavicularmastoid (SCM) is shortened on the involved side by fibrosis, leading to an ipsilateral tilt and contralateral rotation of the face and chin. The aim of this study was to examine the effect of physical therapy and develop a mass diameter prediction model for infants with CMT. Methods: Fifty six patients were diagnosed with CMT between April 2003 and December 2008. Infants with neurological complications, and spasmodic and ocular torticollis were excluded. Physical therapy was applied to those masses in the SCM muscles of those infants after checking their physical findings and the diameter of the mass with ultrasonography. Their physical findings and mass diameter was reevaluated when their neck tilt was under $5^{\circ}$. Results: The mean age when physical therapy was started was 35 days. After a mean 90 days of treatment, the subjects showed improvement in the neck tilt. Subjects whose neck tilted above $15^{\circ}$ showed significant improvement in neck tilt decreased their mass diameter (p<0.01). Facial symmetric infants showed a shorter recovery duration than the facial asymmetric infants (p<0.05). A mass decreasing model based on the diameter of the mass, facial symmetry or not and the physical therapy start day after birth was developed by linear regression. Conclusion: Physical therapy is an effective treatment for CMT. The change in the diameter of the mass on the SCM muscles after treatment can be predicted.

Purpose: Ganglioneuromas are well-differentiated tumors derived from neuroectodermal neural crest cells. Although these tumors can occur anywhere along the sympathetic chain from the base of the skull to the pelvic cavity, they usually develop in the posterior mediastinum and retroperitoneum these tumors are rarely found in the cervical region. Method: We report the case of a 16-year-old male patient with neurofibromatosis type 1 who was admitted because of a palpable mass centrally located on the left side of the neck. A preoperative contrast-enhanced neck computed tomography image showed a low-density homogeneous mass on the parapharyngeal space along with marked displacement of the trachea and carotid vessels. Round and soft masses were also detected on both axillae. Results: The patient subsequently underwent complete excision of the neck mass via the transcervical approach. The mass was smooth and well encapsulated between the sternocleidomastoid muscle and the trachea. Further, the mass appeared to arise from the cervical sympathetic chain, which was preserved during surgery. Both the axillary masses were also excised. The histopathological findings were ganglioneuroma for the neck mass and neurofibroma for both the axillary masses. Conclusion: Cervical ganglioneuromas are rare tumors that present as enlarging parapharyngeal cervical masses in the oropharynx or neck. To our knowledge, a case of cervical ganglioneuroma associated with neurofibromatosis type 1 has never been reported. In patients with neurofibromatosis, multiple tumors may develop, and therefore periodic clinical and radiological follow-up is recommended. Further, repeated imaging analysis should be performed if the presence of another tumor is suspected.

Basaloid squamous cell carcinoma(BSCC) is a high-grade variant of squamous cell carcinoma, with a prediction for multifocal involvement of the base of tongue, pyriform sinus, supraglottic larynx, hypopharynx and palatine tonsil. It primary affects men in the seventh decade of life with frequent cervical lymph-node metastasis at presentation. Grossly, these tumors are usually firm to hard, with associated central necrosis, occuring as exophytic to nodular masses. Histologically, the this infiltrating tumor offers a variety of growth patterns, including solid, lobular, cribriform, cords, trabeculae, nests and glands or cyst. We present a 55-year-old female who was treated with surgical excision and radiotherapy. She was firstly presented as a recurrent inflammatory neck mass and finally diagnosed with basaloid squamous cell carcinoma in the palatine tonsil.

Kimura's disease is a chronic inflammatory disease with unknown etiology. The most common clinical presentation of Kimura's disease is non-tender unilateral mass in the head and neck area, but bilateral involvement has rarely been reported. Histopathological confirmation should be taken for the diagnosis. Various management options are available, including surgical excision, steroid therapy, and radiotherapy. We report a male patient diagnosed as Kimura's disease involving bilateral retro-auricular region. Simultaneous bilateral neck involvement is an extremely rare finding. For cosmetic reasons, the patient was treated surgically, with satisfactory postoperative results. When evaluating patients with mass lesion in bilateral parotid/retro-auricular area, Kimura's disease should be considered as differential diagnosis.

Chondrosarcomas are uncommon disease that are noted almostly in the pelvis, sternum, long bone. Chondrosarcoma in the head & neck was very rare. It can occur in nearly every bone in the head and neck. Lesion of the maxilla is most frequent site in head and neck region, but temporomandibular joint is rare site. In chondrosarcoma of temporomandibular joint, its danger lies in its local invasiveness and potential to seed into the meninges. Histologically, the tumor exhibits myxoid feature, which must be differentiated from chordoma and chondroid chordoma. The cranial nerve palsies frequently observed with the tumors are related to the anatomical location. Chondroma is a benign tumor that most frequently found in the hand, foot bone, but can be originated in any cartilagenous area of body. When it occurs in one site, it is named as solitary enchondroma, and when it occurs in multiple site, it is named as multiple enchondromatosis. In the head & neck, it may occur in the nasal cavity, nasopharynx, nasal septum, eustachian tube, palate. But chondroma that occur as neck mass is extremely rare. Recently, the authors experienced a case of chondrosarcoma confirmed pathology affecting 35-years-old female presenting mass in left temporomadibular joint and a case of chondroma confirmed pathology affecting 26-years-old female presenting neck mass, left.

Angioleiomyoma is benign smooth muscle tumor originating from the vascular wall. While they can occur in various anatomical locations, they are rarely reported in the vallecula region of the oropharynx. We present a case of a 58-year-old female patient with a five-year history of progressive dysphagia and throat discomfort. Laryngoscopy revealed a large, soft, mobile mass located on the right side of the vallecula. Radiological imaging further characterized the lesion as a well-circumscribed, heterogeneous mass. Surgical intervention in the form of Transoral Videolaryngoscopic Surgery (TOVS) was performed, leading to the successful removal of the mass. Histopathological analysis confirmed the diagnosis of angioleiomyoma.

A giant thyroid mass can be associated with severe compressive symptoms, requiring surgery for treatment. This paper reports the case of an 82-year-old man who presented with a giant thyroid mass that was suspected of being a metastatic papillary thyroid carcinoma on fine-needle aspiration cytology. A harmonic scalpel was used to excise the giant thyroid mass. A pectoralis major myocutaneous flap was used for reconstruction. The histopathology assessment confirmed the metastases in the lymph node and papillary thyroid carcinoma in the resected gland.

Thymoma is the most common anterior mediastinal tumor in adults. Rarely, it is presented as the anterior neck mass, commonly located in the anterolateral aspect of the neck or adjacent to the thyroid. We experienced two cases of fine needle aspiration cytology of thymoma, mimicking thyroid mass. The first case was an ectopoic cervical thymoma in a 31-year-old female. The fine needle aspiration cytology was misinterpreted as reactive hyperplasia of lymph node. But the histologic diagnosis was thymoma, predominantly lymphocytic type. The second case was an invasive thymoma in a 66-year-old female, who complained a large anterior neck mass. The fine needle aspiration cytology revealed biphasic population of some clusters of epithelial cells and scattered lymphocytes. The cytologic diagnosis was thymoma and was confirmed as invasive thymoma after the biopsy. Therefore, when the cytologic feature of anterior neck mass shows the both lymphocyte and epithelial component, the differential diagnosis should Include the possibility of thymoma.

Bronchogenic cysts are thought to be uncommon developmental anomalies. They develop from small buds or diverticuli that separate from the foregut in the formation of the tracheo-bronchial tree. They are nearly always located near the tracheal bifurcation; However, these lesions can occur anywhere along the tracheo-bronchial tree. We experienced a case of cervical bronchogenic cyst presenting sorely as an anterior neck mass in a 26-year-old woman. The neck ultrasonography showed as $1.4{\times}1.1cm$ sized hypoechoic lesion with a well-defined margin on the isthmic portion of the thyroid gland. Excision of the mass was carried out. The mass was superfical to the strap muscle and was contained within the subcutaneous tissue in the midline without any connection to the trachea. Grossly, the mass was an oval-shaped cystic lesion which measured 1.5 cm in the greatest diameter. The cyst was filled with thick, yellow, jelly-like material and the inner surface was smooth and glistening. Microscopically, the cyst showed a lining of ciliated columnar epithelium, beneath which was a loose areolar stroma containing plaques of mucous glands and mature cartilage. We thought this cervical bronchogenic cyst appeared to represent an expression of complete aberrent accessory lung bud detachment from the primitive foregut.
