Rhabdomyosarcoma is an uncommon type of soft tissue malignant neoplasm characterized by undifferentiated mesodermal tissue. Sarcomas account for approximately 1% of all laryngeal neoplasm and rhabdomyosarcomas are the rarest sarcoma found in the larynx. When the sarcoma involves the larynx, radical surgery such as laryngectomy has been considered. With recent advances of combined therapy, however, it can be treated by conservative surgeries followed by postoperative radiotherapy and/or pulse chemotherapy. With reviews of literature, we report a 47-year-old patient complaining of husky voice and throat discomfort who was finally diagnosed as rhabdomyosarcoma of the vocal fold and successfully treated by laser cordectomy followed by adjuvant chemoradiotherapy.

Columnar cell variant of papillary thyroid carcinoma (CCV-PTC) is a rare variant representing 0.15-0.2% of all PTCs. The CCV is aggressive, due to its rapid growth, high local recurrence rate, and frequent lung, brain and bone metastasis. Aggressive surgical and medical management are recommended for these neoplasias. The authors experienced a case of CCV-PTC in a 45-year-old man. We performed total thyroidectomy with neck dissection. The patient received radiation and radioactive iodine therapy. There were no recurrences or complications in the following 24 months after the operation. The patient will closely undergo continuous follow up. We present the clinical characteristics, pathology, treatment, and prognosis of the tumor with a review of the literature.

Castleman's disease is an uncommon lymphoproliferative disorder. The disorder can be classified based on histological subtype, such as hyaline vascular type, plasma cell type, and mixed type, and can also be clinically divided into either unicentric or multicentric type. Its exact pathophysiology is not clearly identified. The unicentric type is able to be treated by surgical resection. However, there is no standard treatment modlity for the multicentric type. Treatment of multicentric type includes anti-cancer chemotherapy and radiation therapy. Recently, authors have experienced a rare case of unicentric type of Castleman's disease accompanying a mucoepidermoid carcinoma of parotid gland and report a case which is discussed with references.

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.

The Neurofibroma is a benign neoplasm originating from neural tissue such as Schwann cell, fibroblast and peripheral fibroblast, which rarely converts to malignancy. About 25-45% of neurofibroma are located in head and neck, and the most common sites are lateral cervical region and mouth. Because of its high vascularity and invasion to the adjacent organs, surgical resection may be confronted and limited, moreover large neurofibroma can cause large defect that needs various kinds of flap. The factors related to clinically suspected malignancy are painlessness, abrupt increase in size, firm fixation, and central ulceration, although the malignancy rate of neurofibroma is low. The complete resection was failed several times at local clinic, the patient was transferred to our hospital. We have successfully removed the retroauricular neurofibroma using transposition flap & free skin graft on its large defects.

The extranodal non-Hodgkin lymphoma is uncommonly occurred in larynx, accounting for less than 1% of all laryngeal neoplasm. In general, the laryngeal lymphoma is appeared as submucosal mass without mucosal ulceration and is most commonly found in supraglottis. The primary laryngeal lymphoma constitute a diagnostic challenge because they are characterized by absence of clinical and gross differential criteria, compared with squamous cell carcinoma (SCC). We encountered a 74-year-old man with hoarseness and lump sensation in the throat. On direct laryngoscope, multiple ulcerative and exudative mass in glottis and supraglottic areas were observed. The patient was finally diagnosed as large B-cell lymphoma through the laryngeal microsurgery. He received radiation therapy and there is no evidence of recurrence. Although the laryngeal mass has superficial mucosal change, primary laryngeal lymphoma must be included in the differential diagnosis.

Hemangioma is one of the most common benign neoplasm, which occurs about 50% in head and neck region, but laryngeal hemangioma is relatively rare. Hemangioma occurred in larynx can be treated by surgical removal, cryosurgery, and steroid injection. Transoral CO2 laser micorsurgery has been known as useful method for the treatment of laryngeal hemangioma. We have experienced a 54-years old male patient of hemangioma originated in arytenoid area. This mass was removed via transoral approach with 'en bloc' resection by CO2 laser. We report this case regarding the treatment and prognosis of laryngeal hemangioma with review of literatures.

Mantle cell lymphoma (MCL) is a rare subtype of B-cell neoplasm and it accounts for about 3~6% of all non-Hodgkin's lymphomas. It occurs mainly in middle-aged or elderly man, involving the extra-nodal sites such as gastrointestinal tract, bone marrow and Waldeyer's ring. The incidence of the MCL in salivary gland is about 3%. The blastoid MCL is a rare variant and it has a very aggressive clinical course. It is extremely rare to be arising from the parotid gland. To our knowledge, similar case has not been reported in domestic literature, one case has been described in English literature. We experienced a rare and unique disease entity and report it with brief literature review.

Simultaneous occurrence of medullary and papillary thyroid carcinomas in the same gland is very rare. In fact. there are only 18 cases of simultaneous occurrence of medullary and papillary thyroid carcinomas in the literature. We report a case of simultaneous medullary and papillary carcinoma of thyroid gland. A 67-year-old woman was diagnosed with medullary carcinoma of right lobe of thyroid gland and papillary carcinoma of left lobe of thyroid gland by fine needle aspiration cytology. Total thyroidectomy, anterior neck dissection, bilateral modified radical neck dissection and tracheotomy was undertaken. The tumor metastasized to regional lymph node and extrathyroidal muscle invasion of left papillary carcinoma was also revealed by pathological report. This report describes a case of thyroid carcinoma that demonstrated both medullary carcinoma and papillary components in the thyroid with lymph node metastasis.

Inflammatory myofibrolastic tumor (IMT) is a rare borderline neoplasm. It frequently occurs in the lung but occasionally occurs in extrapulmonary sites such as the genitourinary tract, gastrointestinal tract, breast, salivary glands, sinonasal tract, orbit, and the central nervous system. Laryngeal involvement of IMT is very rare. A 61-year-old woman who complained of hoarseness persisting for 3 months visited our hospital. Laryngoscopy showed an elevated lesion in the right true vocal cord. Incisional biopsy was confirmed as larygeal inflammatory myofibrolastic tumor. We performed a transoral excision with CO₂ LASER under suspension examination. Regional recurrence or distant metastasis was not observed after 9 months of follow-up. Herein we report a case of larygeal inflammatory myofibrolastic tumor that was treated with surgery alone, with a literature review.
