  • Primary malignant melanoma of the mediastinum is extremely rare : To date, there have been only 8 cases reported in the literature. We report a case of a 50-year-old woman presented with an anterior mediastinal mass. The mass invaded the lung parenchyme of right upper lobe, which was wedge-resected with the mass. Microscopically, spindle or polygonal tumor cells with prominent nucleoli and intracytoplasmic melanin pigments are characterized and Fontana stain confirmed the presence of melanin pigment. Immunohistochemical studies showed diffuse positive staining for HMB45, S100 protein and vimentin, which further suggested melanoma.

  • Over the last several decades, the incidence of malignant melanoma has been increasing rapidly. The annual incidence rates have increased approximately 3~7% in Caucasian population. The rate of increase is highest in perimenopausal period in women. The relationship between risk of melanoma and female hormone is still unclear. The safety of hormone therapy for the melanoma patients is not known. We experienced a case of melanoma in whom underwent hormone therapy for 10 years. We report this case with a brief review of literature.

  • Primary malignant melanoma of the esophagus(PMME) is an extremely rare tumor with only scattered case reports. The treatment of choice is surgical resection. However, the prognosis is poor. Recently we experienced one case of primary malignant melanoma of the esophagus in a 60-year-old male patient. Esophagectomy and intrathoracic esophagogastrostomy were perfomed. The patient was discharged without specific complications.

  • Primary malignant melanoma of the esophagus(PMME) is an uncommon neoplasm. And the world literature reports only about 200 cases. A case of primary malignant melanoma of the esophagus is presented, and followed by review of the literature. In our patient, the walnut-sized melanoma was located at the midportion of esophagus and there were two small satellite lesions at the esophagogastric junction. The main mass was diagnosed as primary malignant melanoma histologically and immunohistologically. The tumor was curatively resected by the transthoracic subtotal esophagectomy and the 2 fields node dissection. Post- operative immunotherapy was performed but the tumor recurred 7 months later at the stomach.

  • Primary pulmonary malignant melanoma is an extremely rare type of melanoma. The radiologic features of primary pulmonary malignant melanoma are nonspecific; however, it almost always presents as a well-demarcated round or lobulated solitary solid nodule or mass. Herein, we report the case of a 78-year-old male with primary pulmonary malignant melanoma that was mistaken for primary pulmonary adenocarcinoma with lepidic growth and was seen as bilateral multiple subsolid nodules on CT.

  • Primary malignant melanoma occurring in the lung is very rare and only few cases have been reported in the literatures. We have experienced one case of primary malignant melanoma of the right middle lobe. The patient was a 65-year-old male who had cough with blood tinged sputum for one month. Chest computed tomography showed about 4.5$\times$3 cm sized mass at the right middle lobe encasing the bronchus. Percutaneous needle biopsy was performed and confirmed to malignant melanoma. Physical examination and additional clinical history showed that the mass had not metastasized to other possible primary sites. The patient underwent thoracotomy with right middle lobe lobectomy. Histologically, the tumor showed sheets of tumor cells that have nuclear atypia and melanin pigment Postoperative course was uneventful and the patient has been followed up for 24 months with no recurrence.

  • In the pigmented tumors, the diagnosis of malignant melanoma is not alway easy. Primary mucosal melanoma arising in the nose and paranasal sinuses is a rare disease with a generally poor prognosis. Melanoma in these area is frequently silent at the onset and produces insufficient symptoms to force the patient to the physician in the early stages of the disease. The importance of early recognition of melanoma by the physician is emphasized. We have an experience a case of primary malignant melanoma of the nose and paranasal sinuses in a 36-year-old female and present this case with a brief review of literatures.

  • Malignant melanoma of the oral cavity is rare, accounting for 1 to $8\%$ of all malignant melanomas. The overall prognosis remains poor despite the available treatments such as radical surgery, adjuvant radiotherapy, chemotherapy and immunotherapy due to failure in early detection and tendency in early metastasis. The etiology of mucosal malignant melanoma remains unkown. However, there are few cases of malignant melanoma of the oral cavity reported in the literature, which might be related to preexisting melanosis and radiation treatment. A case with malignant melanoma developed on the same site after 6 years following irradiation for squamous cell carcinoma of the oral cavity is reported in this article.

  • 색소 세포성 모반과 악성 흑색종은 형태가 유사하지만 유해성의 측면에서 악성 흑색종은 암으로써 무해한 색소 세포성 모반에 비해 위험한 질환이다. 이에 기반하여 기존 연구에서 색소 세포성 모반과 악성 흑색종을 구분하기 위한 연구가 있었지만, 데이터를 취득하는 과정에서 많은 cost 가 필요하였다. 본 연구에서는 이를 개선하기 위해 두 병변의 dermatoscopic 영상을 분류 학습의 데이터로 사용하여 연구를 진행하였다. 학습을 위한 데이터는 오픈소스 dermatoscopic 데이터셋인 HAM10000을 사용하였으며 모델은 CNN 에서 개선된 MobileNetV2 를 사용하였다. 실험 결과, MobileNetV2 를 사용한 학습은 3-layer CNN 에 비해 15 분의 1 가량 적은 파라미터를 가졌으며, 검증 성능과 테스트 성능에서 93%에 근사하는 성능을 보였다. 본 연구는 이전 연구에 비해 cost 측면에서 큰 개선을 이루었으며, 상용화 가능한 분류 기법을 발견했다는 점을 시사한다.

  • A primary malignant melanoma of the vagina is a very rare gynecological malignant tumor. Its clinical behavior is more aggressive than that of cutaneous and vulvar melanomas. We present a case of a large sized primary melanoma of the lower third of the vagina, with a cervical lesion, in a 58-year-old postmenopausal woman. The patient was treated with conventional external radiation therapy and intracavitary radiotherapy (ICR), without surgical treatment. Although the primary lesion showed a partial response, the patient died of extensive metastases, which were found 4.5 months after the initial diagnosis. We suggest that shortening the treatment period, such as hypofractionated radiation therapy and surgical removal, and various systemic therapies for preventing early distant metastasis, are appropriate treatments for a primary malignant melanoma of the vagina, with a large tumor size.
