Epstein-Barr virus positive diffuse large B-cell lymphoma is very rare malignant tumor in thyroid gland. Compared to Epstein-Barr virus negative diffuse large B-cell lymphoma, it tends to have more extranodal involvement, does not respond to chemoimmunotherapy well, and has worse prognosis. We have encountered a patient with Epstein-Barr virus positive diffuse large B-cell lymphoma of thyroid gland in 75-year-old female presenting with aggravating dyspnea and neck pain.

Follicular dendritic cell sarcoma (FDCS) is rare lymphoid sarcoma occurs anywhere in body, mostly in lymph nodes. Sixty-two-year-old man presented left submandibular gland region mass for 5 months. Mass excision with submandibular gland resection was performed. Histopathology showed proliferation of spindle and ovoid cells with storiform arrangement which were positive for CD21, CD23, Vimentin, Ki-67, suggested FDCS in submandibular gland region lymph node. Tumor size was 3cm with no involvement of resection margin, nor cellular atypia and necrosis, so regular follow up was performed. After 4 years, new enhancing mass in left submandibular area was found. Wide excision of mass with neck dissection on left level I-III was performed. Histopathology confirmed recurrence of FDCS. The patient underwent radiation therapy from left mandible to hyoid area. After 2 years, new nodule was found in left lung upper lobe, and wedge resection confirmed metastasis of FDCS. The patient is on adjuvant chemotherapy.

Pilomatricoma is characterized by a semi-transparent epidermis, especially pigmented pilomatricoma, containing melanocytes in basaloid cells, which are dark and purple, resembling vessel-derived skin masses. If the vascularity at doppler ultrasound is high before surgery, it may be misdiagnosed.A 10-year-old female patient visited our clinic because of a mass in the right ear triangular fossa. Ultrasonography was performed, and a vascular-origin tumor was suspected because of the high vascularity. The excised mass was diagnosed as pigmented pilomatricoma by a pathologist.Pilomatricoma is mistaken for other masses owing to its various phenotypes. A misdiagnosis can lead to misdirected strategies which can cause delayed treatment and can result in an increase in the size of the pilomatricoma, making the sequalae of surgery more complicated. For proper treatment, careful examination and evaluation are required before surgery.

Solitary fibrous tumor (SFT), which was initially believed to be a subtype of mesothelioma, has been reported to occur outside the pleura. In the head and neck region, it primarily manifests in the oral or nasal cavity, with rare occurrences in the facial region. A 40-year-old woman visited our hospital with a mass on her chin. Prior to surgery, involuntary movement was observed in the ipsilateral corner of the mouth upon palpation of the mass. Special care was taken during the surgical procedure to avoid damaging the facial nerve. The mass was excised, and histological examination and immunohistochemical analysis confirmed the diagnosis of an SFT. Here, we present the first reported case of an SFT diagnosed in a jaw mass in Korea. The objective of this study was to highlight the importance of the diagnostic accuracy of SFTs in lower jaw masses.

Neck masses can have various origins and diverse presentations, making accurate diagnosis challenging. Schwannomas and lymphoepithelial cysts are commonly encountered neck tumors, and it is hard to get differential diagnosis. A 50-year-old woman presented with a progressively enlarging right neck mass discovered five years ago. Upon examination, a 3 cm firm, non-tender, and mobile tumor was found in the right neck level II region. Imaging studies suggested a tumor originating from the cervical sympathetic chain. The patient underwent a resection of the tumor under general anesthesia. Postoperative follow-up showed no complications or signs of recurrence. However, contrary to the initial suspicion of a schwannoma, the final pathological examination revealed a lymphoepithelial cyst. In this paper, we present a case of a cervical lymphoepithelial cyst misdiagnosed as a schwannoma, aiming to compare the clinical and histological characteristics of these two tumors and provide insights into appropriate diagnosis and management.

Ewing sarcoma is a rare tumor in head and neck area. We demonstrate a rare case of sinonasal Ewing sarcoma initially suspected as olfactory neuroblastoma. After the surgery and immunohistochemical studies, it was accurately diagnosed as Ewing sarcoma. We would like to emphasize the possibility that Ewing sarcoma may originate from the head and neck area, and hence, it is important to use appropriate techniques for accurate diagnosis and treatment.

The primary treatment of oral cavity cancer is still surgery. By discussing the surgical treatment of oral cavity cancer, the basic concept of head and neck surgery could be thoroughly reviewed. The oral cavity is defined as the hard palate and the anterior 2/3 of the tongue. With appropriate reconstruction, most defects can be repaired without a significant change in quality of life, unlike in the oropharynx or hypopharynx, where aspiration problems frequently occur. The selection of a surgical approach that can provide an appropriate field of view to obtain a resection margin of 5 mm or more has become the core of head and neck surgery. The role of prophylactic neck dissection is also well established in oral cavity cancer patients. Mandibulotomy for access to the oral cavity or mandibulectomy due to cancer invasion requires bony surgical techniques, and reconstruction also requires bone tissue reconstruction techniques as well as soft tissue. Therefore, oral cancer surgery is the most important primary area where all techniques of head and neck surgery are mobilized.

Lipomas are a common soft-tissue tumor of mesenchymal origin, but intermuscular lipomas are very infrequently found especially in the cervical region. Although lipoma itself rarely causes complications, an accurate diagnosis and appropriate treatment are important. Surgical excision is indicated for deep lipomas that are 5 cm or larger, grow, or are accompanied by symptoms such as pain. It is also important to differentiate malignant tumors through pathological examination. Since the size of the lipoma was large, lipoma was divided into several pieces to successful removal, and the patient in this case showed successful recovery after surgery.

A plunging ranula is a pseudocyst caused by mucus secreted from the sublingual glands, and it is mainly observed on the mouth floor. Nowadays, sclerotherapy using picibanil has been performed instead of invasive surgical treatment, and studies are reporting safe and effective outcomes. In our study, more than 92% of the 25 patients had marked response after picibanil sclerotherapy, and no serious complications were observed. Picibanil sclerotheraphy can be considered as the primary treatment of plunging ranula for patients who refuse surgery under general anaesthesia.

In general, the anatomical location and number of parathyroid glands are well known, but they are often found in a variety of locations, making it difficult to find parathyroid glands during surgery. Besides Intra-thyroidal parathyroid adenoma is extremely rare case, and it is harder to identify in surgery. We encountered a 51-year-old patient with a thyroid nodule. The results of the additional blood test and the Tc-99m MIBI were combined to determine that the left lower lobe parathyroid adenoma was highly likely. This patient was treated with left thyroid lobectomy with parathyroid identification using Near-infrared (NIR) imaging. Afterwards, the biopsy confirmed that it was a parathyroid adenoma, and has since been monitored through outpatient observation without any problem. We present this rare case with a review of related literatures.
