A granular cell tumor (GCT) is a rare soft tissue tumor that usually arises from the striated muscle of the tongue. Few literatures have reported pectoral muscle involvement of the GCT. Herein, we report a rare case of a GCT originating from the pectoral muscle below the breast with multimodal imaging appearance.

Hemangiomas are the most common benign tumors or tumor-like malformations of blood vessels or blood filled cavernous spaces. Hemangiomas of the oral cavity represents 14% of all hemangiomas. Most hemangiomas are detected by one year of age and most commonly occurred in the lips, tongue, buccal mucosa and palate. But hemangiomas are sometimes reported in adults. We report one case of extensive hemangioma of the tongue in adult. Our case is a 48-year-old male who presented with a hemangioma occupying entirely two-third of the tongue. Treating those lesions pose a challenge to the surgeon. This paper discusses one case of extensive tongue hemangiomas treated with alcoholic sclerotherapy with satisfactory results supporting this particular approach in the management of these lesion.

Schwannoma, also named neurilemmoma, is a rare solitary and slow-growing tumor which originates from schwann cells of the nerve sheath. Schwannoma is a well-circumscribed, encapsulated masses that is attached to the nerve but can be separated from it. On microscopic examination, tumors show a mixture of two growth patterns, Antoni A and B. Surgical excision is the treatment of choice. Especially, Schwannoma of the tongue is very rare. We present a case of a 11-year-old child with a schwannoma of the tongue, measuring $1{\times}1cm$. During the operation the mass revealed itself as being encapsulated. The tumor was removed and diagnosed pathologically as a schwannoma.

The tongue, especially its lateral part, is the most common site of oral tumors. Patients who undergo glossectomy for the treatment of tongue cancer may experience difficulty in proper functioning for pronunciation, chewing, swallowing, and oral hygiene maintenance; therefore, a palatal augmentation prosthesis can be used to restore function of the tongue. In this case, an implant overdenture was used in a patient who had residual ridge resorption and obliteration of alveololingual sulcus after undergoing glossectomy for tongue cancer treatment. In addition, a palatal augmentation prosthesis with a metal framework, support, and retention part was fabricated. The palatal vault was reduced, so that even with limited tongue movement, adequate tongue-palate contact could be achieved. After placement of the definitive prostheses, the patient showed improvement in the functions of chewing, swallowing, and pronunciation.

Mucinous adenocarcinoma is rarely reported in head and neck region. In other organ, it usually occur in breast, gastrointenstinal tract and so on. The specific histologic findings of mucinous adenocarcinoma are the large amount of extracellular mucin and tumor cell nests such as floating in mucin pool. It may develop rarely in major or minor salivary gland, but only one case of mucinous adenocarcinoma originating from parotid gland was presented in south korea. We report a case of mucinous adenocarcinoma in the tongue base considered to develop from minor salivary gland with a review of literatures.

Tongue osteoma is a rare disease. Clinically, it occurs mainly in the posterior part of the tongue and may cause foreign body sensation, but most of it is found incidentally without any symptom. Clear mechanisms of development have not yet been established, but many hypotheses have been proposed. Treatment is possible with surgical resection and no recurrence or malignancy has been reported. We experienced a 29 year old man with osteoma of tongue. We report this case with a review of literature.

Osseous choristoma is a rare, benign proliferative osseous lesion, which is defined as the growth of normal tissue in an abnormal location. The etiopathogenesis for its formation is unknown, but various hypotheses have been proposed. Treatment of choice is en-bloc resection, and no recurrence has been reported. Here, we report the two cases of osseous choristoma, presented with a mass on the base of the tongue with/without globus symptom and were treated with surgical excision.

Granular cell tumors (GCT) are uncommon benign neoplasms. Their location is mostly in the the skin, tongue, and breast; appearance in other parts of the body is rare, but it has been reported. They have also been reported to occur synchronously in multiple organs and metachronously in a single organ. The incidence of GCTs in the tracheobronchial tree is unknown and pulmonary GCTs are uncommon, with approximately 100 reported cases in the literature. We present the case of a 33-year-old man with a granular cell tumor of the left main bronchus. The tumor was found at bronchoscopy performed to exclude suspected endobronchial mass with symptoms of pneumonia. Biopsies revealed the histological pattern of a benign granular cell tumor. He underwent resection of the left main bronchus followed by end to end anastomosis of left main bronchus. He has not had any recurrence of the tumor during the 1 year follow-up.

A 7-year-old castrated male Boston terrier dog was referred due to dyspnea and unilateral cervical mass. On physical examination, mass on left submandibular region was palpated. CT findings revealed this case could be the tumor originated from left lingual vein. The client refused further treatment and the patient expired because of respiratory failure 10 days after presentation. On necropsy, a well-defined firm mass which located in the left side of larynx was detected. Histopathological findings for the mass indicated polygonal tumor cells arranged in nest and separated by fibrovascular septa. We performed immunohistochemisry to evaluate of chromogranin A and tumor cells showed positive immunoreactivity for chromogranin A. Based on computed tomography (CT), histopathological and immunohistochemical findings, this case was definitely diagnosed to paraganglioma of the body on the lingual vein. This report describes the clinical findings, CT imaging characteristics, histopathologic and immunohistochemical features of paraganglioma arised from lingual vein in a dog.

Extranodal Natural Killer (NK)/T-cell lymphoma, nasal type, is a subtype of non-Hodgkin lymphoma, strongly associated with Epstein-Barr virus. Extranodal NK/T-cell lymphoma mostly affects the nasal cavity and there has been no report of the disease's occurrence at the base of tongue. Here we report a case of 43-year-old man who presented with a diffuse ulcerative lesion at the base of tongue. Because the patient had oral bleeding, tracheostomy and lingual artery ligation was performed via a transcervical approach to control bleeding and protect the upper airway. We performed a deep biopsy through the lateral pharyngotomy approach, and finally, the patient was diagnosed with extranodal NK/T-cell lymphoma, nasal type. We report this rare case of extranodal NK/T cell lymphoma at the base of tongue with a literature review.
