Liposarcoma is a malignant tumor originated from adipose tissue, accounting for 20% of all soft tissue sarcomas. A 69-year-old man with anterior and posterior neck mass visited to our department and we performed an excisional biopsy in level I. Histopathological examination revealed liposarcoma, so we performed wide excision in anterior and posterior neck, and adjuvant radiotherapy. We report a unique case of well-differentiated liposarcoma on anterior and posterior neck with literature review. To our best knowledge, such case has not been reported earlier in Korea previously.

Salivary gland tumors take possession of almost 5% in head and neck malignancies. Among these, mucoepidermoid carcinoma(MEC) is most common malignany in major salivary glands(12-29%) and the parotid gland is most predilection site. Intra-oral MEC has a tendency to various locations, and the predilection sites are palate, cheek, mandible, lip and tongue in order of frequency. A few cases of MEC are occurred in with retromolar trigone, oropharynx, and ectopic salivary gland. Recently, we experienced a-65-year old woman with retromolar trigonal mass, and she was finally diagnosed as MEC. We report it with review of literature.

Warthin's tumor (WT) is second most common neoplasm in the parotid gland and it can be accompanied by inflammation and necrosis. The chest wall inflammation may present a rapid and fatal clinical course and secondary to parotid abscess is extremely rare. An 81-year-old man came to emergency room complained of rapidly enlarged left parotid mass and inflammatory symptoms and signs around the upper lateral neck. We performed incision and drainage with adequate infection control. He was pathologically diagnosed as abscess. We report the unique and instructive clinical case with a literature review.

Angiokeratomas represent vascular lesions and are histologically characterized by superficial dermal vascular ectasia with overlying epidermal hyperkeratosis. Angiokeratoma circumscriptum is one of five types in the group of the angiokeratomas. The lesion is present from birth but may appear in childhood or adulthood. Angiokeratoma circumscriptum is typically hyperkeratotic papules or nodules situated unilaterally on the foot or distal aspect of the leg, but can occur elsewhere on the body. Isolated tongue involvement is very rare. We report a 12-year-old boy with angiokeratoma circumscriptum of the posterior dorsal tongue with a review of the literatures.

Liposarcoma is a very rare malignant tumor affecting the head and neck area. Since it is an invasive and life-threatening disease, active treatments is necessary. However, differential it from lipoma, its corresponding benign counterpart, may be difficult. Herein, we report a rare case of posterior neck myxoid liposarcoma in a 72-year-old man who was initially misdiagnosed with lipoma, including a literature review of differential diagnosis between lipoma and liposarcoma.

Purpose: The purpose of this study was to investigate the effect of customer experience management on nursing service satisfaction of cancer patients and their intent to revisit the hospital and also to identify empathy ability of oncology nurses. Methods: Participants were 376 cancer patients and 190 oncology nurses from a tertiary hospital in Korea. Cancer patients' satisfaction with nursing care and intent to continue using the hospital were measured and empathy of oncology nurses was measured using Empathy Construct Rating Scale. Data were analyzed using descriptive statistics, ${\chi}^2$ test, t-test, one-way ANOVA and stepwise multiple regression analysis. Results: Patient satisfaction with nursing care and intent to continue using the hospital were higher in patients who received the customer experience management program than those who did not. Oncology nurses' ability to empathize was high. Clinical career, participate in customer experience management and education level together explained 20% of variance in empathy ability of oncology nurses. Conclusion: Findings from this study confirm that customer experience management affects patient satisfaction with nursing service and intent to continue using the hospital. Further research is necessary to reaffirm the empathy ability of the oncology nurses and to identify the related various factors.

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.

Hyalinizing trabecular tumor (HTT) of the thyroid gland is a rare neoplasm and only less than 100 cases have been reported so far. It is characterized by hyalinizing stroma with trabecular growth pattern and has an indolent clinical course. Because of its histologic features, it is frequently misdiagnosed as papillary or medullary carcinoma in fine needle aspiration cytologic findings. The tumor is benign or low malignant potential and thyroid lobectomy is recommended for adequate treatment. We recently experienced a case of thyroidal HTT in a 57-year-old man, who presented with a right thyroid nodule that was suspicious of papillary carcinoma in aspiration cytology. We report the unique and rare disease entity with brief literature review.

Ganglioneuroma (GN) is benign neurogenic tumor arising from ganglia of the sympathetic nervous system. They are mostly found at posterior mediastinum, retroperitoneum, and adrenal gland, whereas only 1-5% occurred in the cervical region. GN usually present as a single, painless and slow-growing mass, but multiple cervical occurrences are extremely rare. An 80-year-old woman came to our clinic complained of posterior neck mass for three years. We performed surgical excision, and it was finally diagnosed as GN. We report the unique and rare disease entity with a brief literature review.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of malignant lymphoma (ML), accounting for only 1 to 2% of all non-Hodgkin's lymphoma (NHL). Although ML of the parotid gland is rare, the majority are B-cell types. The AITL occurring synchronously in the parotid gland and lateral neck has not been reported earlier. It is classified as a high-grade malignancy with aggressive clinical features, and the prognosis is worse than any other type of NHL. We recently encountered a 72-year-old man with multiple mass on the ipsilateral parotid tail and lateral neck, and he was finally diagnosed as AITL. We report the unique and rare disease entity with a brief literature review.
