There are many treatment options for the malignant melanoma. Wide excisional surgery is one of the most acceptable treatments for locoregional treatment. Depending on the pathologic classification, however, some other treatment option can be included such as chemotherapy, radiotherapy and immunotherapy as adjuvant treatment. Small cell type malignant melanoma is a rare variant of malignant melanoma. It is known that melanomas manifesting this morphology are invariably in vertical growth phase and have an aggressive course. The authors encountered small cell type malignant melanoma and would like to share the experience of successful treatment with surgery plus immunotherapy as one of adjuvant treatment options.

Chronic invasive fungal sinusitis (CIFS) is a relatively rare disease which occurs in immunocompetent or immunocompromised patients. We report a case of CIFS in ethmoid sinus with concurrent fungal ball in maxillary sinus. After surgical debridement and antifungal therapy, CIFS recurred with submucosal invasion in nasopharynx and osteomyelitis of clivus. Although CIFS encompasses a slowly progressing invasive fungal disease but potentially aggressive. It should be noted that CIFS could progress and extend through submucosal route without evidence of mucosal lesion.

It is important to choose which approaches should be used to correct the fracture if the operation is indication for surgery in patients with orbital floor fracture. Transorbital, transantral, and endonasal approaches are methods for correcting the orbital floor fracture. The approach needs to be considered the location of the fracture, the degree, the severity of the fracture, the least remaining patient's disability, and preference of the surgeon. We report a case of orbital floor fracture using transorbital approach and endonasal catheter ballooning to resolve the limitations of transorbital approach alone.

Liposarcoma is a malignant tumor that occurs in adipocytes, accounting for 5% of all sarcomas. Generally, it has no symptoms and it occurs in any parts of the body. There are various types of liposarcoma. Of these, 40-45% are known as highly differentiated liposarcoma, and highly differentiated liposarcoma is also referred to as atypical lipomatous tumor. We report a case of an atypical lipomatous tumor on the left neck.

현장조사학습은 학습자로 하여금 생생한 현실에 직면하게 함으로써 보고 듣고 느끼는 구체적인 학습을 통하여 생활경험과 시야를 넓히고 사회사상 간의 관계를 보다 잘 이해할 수 있게 하며 사회과 교수, 학습과정에서의 문제해결을 위해 교실을 벗어나 고장을 중심한 우리도의 현지학습을 위주로 하는 것을 말한다. 그러나 21세기 정보화시대를 맞아하여 우리는 수많은 정보를 일일이 다 경험하기에는 한계가 있으며 현실적으로도 매우 어려운 실정이다. 또한 초등학교 사회과 편성의 주요방향인 정보화능력을 바탕으로 학습자가 정보화 사회에 나아가 다양한 정보를 취득하고 활용하여 현대사회의 문제를 창의적이며 합리적으로 해결하는 능력을 길러야 한다. 이러한 능력을 기를 수 있는 기틀을 마련해 주기위해 학습자가 원하는 시간과 장소에서 자기 학습력과 속도에 맞춰 자기 주도적인 학습을 할 수 있도록 학습자에게 다양한 미디어를 결합시킴 형태의 WBI를 설계하고 구현하여 학습효과를 극대화 하고자 한다. 본 연구에서는 사회과 4학년 1학기 보조교과서 "우리 경상남도의 생활"을 재구성하여 서부경남의 7개 시 군의 교통, 관광, 인구, 특산물, 문화재, 등에 대하여 정보를 탐색, 분석, 활용할 수 있는 능력을 길러주고자 한다.

Immunoglobulin G4-related disease (IgG4RD) is a chronic inflammatory condition characterized by tissue infiltration with lymphocytes and IgG4-secreting plasma cells, as well as varying degrees of fibrosis. We report a case of a 70-year-old man with a rapid-growing cervical mass for several months. Computed tomography and positron emission tomography showed a huge, ill-defined mass involving left thyroid lobe and encasing the common carotid artery, which was clinically and radiologically suspicious for anaplastic thyroid carcinoma. Ultrasonography-guided core needle biopsy was performed and histopathology examination revealed to be consistent with IgG4RD, and the IgG4/IgG ratio was 0.6. After oral corticosteroid was administered, the mass was dramatically resolved. Because IgG4RD often presents as a single localized and infiltrated mass lesion, it can be confused and misdiagnosed as a malignancy. Thus, clinicians should consider IgG4RD as a differential diagnosis in a rapid-growing neck mass to prevent unnecessary and excessive treatments.

Sparganum is the larvae of a parasite called Spirometra. It usually lives in snakes or frogs, which are parasitic on the human who consume them raw. Sparganum is presented with a form of mobile subcutaneous nodule in various parts of human body. A 78 years old man with palpable neck mass visited our clinics. He had a history of eating snakes raw about 50 years ago. He was diagnosed with Sparganosis through a fine needle aspiration biopsy and underwent excisional biopsy. Sparganosis should be considered when dealing subcutaneous palpable neck mass with history of consuming raw snakes or frogs.

Papillary thyroid carcinoma (PTC) is the most prevalent type of thyroid cancer. In contrast, thyroid lymphoma is a very rare disease. Concurrent onset of both is very rare in the thyroid gland. Ultrasound (US)-guided Fine needle aspiration (FNA) is a useful diagnostic tool, but occasionally pathology results may change after the surgery. A 56 years old woman visited with Hashimoto's thyroiditis and nodule on the thyroid gland isthmus on US exam. US-guided FNA was performed at thyroid nodule and diagnosed as PTC. The patient underwent total thyroidectomy. The pathological findings revealed a mucosa associated lymphoid tissue (MALT) lymphoma accompanied with PTC. Authors report this unusual case with a review of literature.

Granulomatosis with polyangiitis (GPA) and Immunoglobulin (Ig) $G_4$-related disease ($IgG_4$-RD) are rare diseases and early diagnosis and proper management are imperative to prevent multi-organ damage. The authors present a case of a 60 years old woman who had facial paralysis and hearing loss. Lt intact canal wall tympanomastoidectomy, Lt facial nerve decompression and ossiculoplasty with partial ossicular replacement prosthesis (PORP) was done. During operation, middle ear tissue was biopsied and GPA with $IgG_4$-RD was diagnosed. After methyl prednisolone (MPD) pulse therapy and azathioprine therapy, the severity of paralysis was improved. We present this case because common otologic symptoms like facial palsy and hearing loss could be initial symptoms of rare systemic disease.

Neurilemmoma is a benign tumor that originates from the Schwann cell. It frequently occurs in head and neck regions, but neurilemmoma of external auditory canal is extremely rare. Here, we report a very rare case of 36-year-old male with a tumor located in the posterior wall of external auditory canal, preoperatively suspected as neurilemmoma originated from Arnold's nerve by temporal bone magnetic resonance imaging. The tumor mass was surgically excised and pathologically confirmed as a neurilemmoma.
