Most neoplasm of the floor of the mouth are squamous cell carcinoma. They originate from anterior midline floor of the mouth and penetrate into the sublingual gland. Invasion of the mandible is a late manifestation. Lymphatic spread is the submaxillary and subdigastric nodes and advanced lesions of them produce severe pain, The initial step in managing patients with cancer pain is the oncology therapy in the form of radiotherapy, surgery, or chemotherapy, alone or combined. When oncologic therapy is ineffective, the pain must be treated by systemic analgesic, psychologic, neurostimulating, regional analgesic,and meuroablative techniques. We successfully treated with gasserian ganglion block on the left side and mandibular nerve block on the right side with pure alcohol in the patient having severe submandibular, lower lip and tongue pain.

Dermoid cyst is a benign neoplasm, so called by teratoma that is derived from both ectoderm and mesoderm during embryonic period. The majority of dermoid cysts are found in the ovaries and approximately only 7% of dermoid cysts are found in the head and neck. The growth of dermoid cysts in the floor of the mouth is considered a rare condition. We report one case of huge dermoid cyst in the floor of mouth suffered with double chin appearance and difficulty in pronunciation and respiration. The cyst was excised successfully only intra-oral incision. Clinical progress was uneventful and postoperative recovery excellent without recurrence.

Purpose: This study was done to investigate the effects of pilocarpine mouth care on the condition and discomfort of the oral cavity in patients with terminal cancer. Method: A quasi-experimental design with a non-equivalent control group, pre- and post-test was used. The participants were 30 patients admitted to the hospice care unit of C university hospital. Fourteen patients received pilocarpine mouth care for 5 days. The other sixteen received general mouth care. Results: Improvement in the condition of the oral cavity was significantly higher in the experimental group compared to the control group. Decrease in oral discomfort scores was significantly higher in the experimental group compared to the control group. The incidence of oral candidiasis was significantly higher in the control group compared to the experimental group. Conclusion: These findings indicate that pilocarpine mouth care could be an effective intervention for relieving oral discomfort, improving the condition of the oral cavity, and decreasing the incidence of oral candidiasis in patients with terminal cancer.

Objectives: Leiomyosarcoma is a malignant neoplasm that affects smooth muscle tissue and it is very rare in the field of oral and maxillofcial surgery. The purpose of this study was to obtain information on diagnosis of and treatment methods for leiomyosarcoma by retrospectively reviewing of the cases. Patients and Methods: The study included nine patients who were diagnosed with leiomyosarcoma in the Department of Oral and Maxillofacial Surgery at Seoul National University Dental Hospital. The subjects were analyzed with respect to sex, age, clinical features, primary site of disease, treatment method, recurrence, and metastasis. Results: Particular clinical features included pain, edema, mouth-opening limitations, dysesthesia, and enlarged lymph nodes. All cases except one were surgically treated, and recurrence was found in two cases. Four of nine patients were followed up without recurrence and one patient underwent additional surgery due to recurrence. Conclusion: In our case series, notable symptoms included pain, edema, mouth-opening limitations, and dysesthesia; however, it was difficult to label these as specific symptoms of leiomyosarcoma. Considering the aggressive characteristics of the disease and poor prognosis, surgical treatment is necessary with careful consideration of postoperative radiotherapy and chemotherapy.

Solitary fibrous tumor(SFT) is a spindle cell neoplasm that usually arises in the pleura. Its involvement of the meninges is rare but increasingly being reported. Our case was a 33-year-old man who presented with clonic seizure around the right mouth angle and sensory disturbance at the right hand. Radiological studies showed a large extra-axial, dural-based mass in the left fronto-parietal region, typically isointense with gray matter and heterogeneous strong enhancement on T1-weighted images. Histologically, the tumor was composed of spindle-shaped cells growing in fascicles within the collagenous matrix. Immunohistochemical staining demonstrated diffuse CD34 positivity. Awareness of this neoplasm is necessary to accurate diagnosis.

Sclerosing polycystic adenosis (SPA) is a rare, asymptomatic disease that occurs mainly in the salivary glands. We report the case of a 51-year-old man who presented with trismus and pain upon mouth opening. Magnetic resonance imaging revealed a 2-cm mass located in the anterior portion of the left parotid gland. SPA was diagnosed based on histopathological examination of the surgical specimen. In pathologic findings, there was a well-circumscribed multicystic nodule in the parenchyma. Dense fibrosis and chronic non-specific inflammatory cells were observed in the stroma. In 13 previous reports on SPA, the most preferred treatment was superficial or total parotidectomy. This report suggests that simple excision of SPA preserves facial nerve function and facial volume.

Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.

Lipoma is the most common benign neoplasm of the body with rare occurrence in the oral cavity. It represents 1~4% of benign neoplasms of the mouth, which affect the buccal mucosa, floor of the mouth, tongue and lips. We report a case of lipoma in the labial vestibule with extraoral swelling, which could easily be misdiagnosed as an odontogenic abscess. Excisional biopsy in this case revealed well-circumscribed masses, surrounded by a thin fibrous capsule and composed of sheets of mature adipocytes, arranged in a "chicken wire" configuration. After a computed tomography scan, excisoinal biopsy was done, and there were no recurrence after 5-month follow-up period.

Lipoma is most common tumor that compromises 4% to 5% of all benign neoplasm, but in oral cavity it is uncommon. In oral cavity, lipoma presents painless, asymptomatic, slow growing, but sometimes it grows to larger size causing deformities, mastication and speech difficulties. While lipoma in commonly affects female patients (68-73%), oral lipoma appears more frequently in male patients. The majority of oral lipoma is seen after the age of forty (uncommon in children). Lipoma of oral cavity and maxillofacial region occurs most commonly in the parotid region, followed by the buccal mucosa, lip, tongue, palate, mouth floor, gingiva in order. A treatment of lesion is surgical excision with recurrence not expected. In this paper we present the case of a patient who has Lipoma in the mouth floor.

Ameloblastoma is the most frequently accuring odontogenic tumor in mouth. The biologic behavior of this neoplasm is locally invasive tumor with a high rate of recurrence. But in case of unicystic ameloblastoma, it was known that the neoplasm can be treated by marsupialization and the recurrence rate is lower. In our clinic, we tried to treat one of ameloblastoma cases by marsupialization and finished the treatment by enucleation via intra-oral approach with sagittal ramus osteotomy. This is a report of that case about 29 years old female patient.
