  • Background and Aim: Currently available systemic therapies for malignant melanoma produce low response rates in patients, and more effective treatment modalities are clearly needed. The tumor necrosis factor (TNF)-related apoptosis-inducing ligand has a significant impact on therapy for patients with X-linked inhibitor of apoptosis protein-downregulation malignant melanoma. The primary objective of this study was to assess its therapeutic potential. Materials and Methods: We employed a conditionally replicating oncolytic adenoviral vector, named CRAd5.TRAIL/siXIAP, with the characteristics of over-expression of the therapeutic gene TRAIL and downregulation of XIAP in one vector. B16F10-luc cells were employed to detect anti-tumor activity of CRAd5.TRAIL/siXIAP in vitro and in vivo. Results: CRAd5.TRAIL/siXIAP enhanced caspase-8 activation and caspase-3 maturation in B16F10 cells in vitro. Furthermore, it more effectively infected and killed melanoma cells in vitro and in vivo than other adenoviruses. Conclusion: Taken together, the combination of upregulation of TRAIL and downregulation of siXIAP with one oncolytic adenoviral vector holds promise for development of an effective therapy for melanomas and other common cancers.

  • We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.

  • Objectives : It is the aim of this study to derive lurker studies evaluating the effectiveness of bee-venom phamacopuncture on malignant melanoma patients. We present a patient of malignant melanoma at right maxilla who survives over one year with stable disease (SD) by the treatment of Bee Venom Phamacopuncture (BVP). Methods : We followed the treatment and examination. We prescribed to the patient what to be taken 1.5cc BVP once a day. Picture series, Head series were followed-up and Neck computed tomography (CT) and positron emission tomography computed tomography (PET CT) were performed to evaluate the therapeutic efficacy. Results : The patient survives over one year and continued stable disease over 6 months. Picture series, Head series X-ray, neck CT and PET CT were shown no interval change. Conclusion : This case may give us the possibility that BVP offers potential benefits for patients with malignant melanoma.

  • A 14-year-old neutered-male Shih-Tzu was referred for glaucoma and hyphema accompanied by systemic hypertension. After topical corticosteroid and antiglaucoma medications, the left eye (OS) progressed phthisically, but ocular hypertension redevelop one-year-and-seven-months later. Suspected limbal melanoma developed in peripheral cornea/limbal sclera with heavily pigmented cornea OS. Ultrasound biomicroscopy and ocular ultrasonography differentiated ciliary body origin-heterogeneous mass from limbal mass. Persistent hyphema and pigmented cornea might obscure intraocular lesion and advanced diagnostic methods played a crucial role. Unlike the generally benign limbal melanoma, aggressive treatment was recommended for uveal tumor. Histopathology of enucleated OS confirmed malignant uveal melanoma with chronic hypertensive vasculopathy.

  • We report the case of a 33-year-old male who presented with a malignant melanoma on his anterior chest wall. The lesion was only found in the red ink pigment of the tattoo, as were several in-transit dermal metastases. Possible explanations include a pre-existing lesion which was seeded with red ink or the possibility of the red ink causing an inflammatory reaction leading to malignant transformation. This is the first reported case of a melanoma developing in the red ink pigment of a multi-colored tattoo.

  • Herein we report a rare case of primary esophageal malignant melanoma in a 56-year-old gentleman who presented with a 2-month dysphagea. Esophagoscopy reveals a polypoid tumor and a total thoracic esophagectomy was performed through a right thoracotomy and esophageal replacement with stomach. The tumor was proven to be a primary esophageal malignant melanoma by histological and immunohistochemical studies. The pathologic stage was IIa. He received no postoperative adjuvant therapy. He died of liver metastasis at 8 months postoperatively.

  • Primary intracranial malignant melanoma is a very rare and highly aggressive tumor with poor prognosis. A 66-year-old female patient presented a headache that had been slowly progressing for several months. A large benign pigmented skin lesion was found on her back. A brain MRI showed multiple linear signal changes with branching pattern and strong enhancement in the temporal lobe. The cytological and immunohiostochemical cerebrospinal fluid examination confirmed malignant melanoma. A biopsy confirmed that the pigmented skin lesion on the back and the conjunctiva were benign nevi. We report a case of primary intracranial malignant melanoma and review relevant literatures.

  • 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.

  • While oral melanotic macule is regarded as the most frequent oral pigmented lesion without any harmful symptom, oral melanoma is a very rare and life-threatening disease among oral pigmented lesions. Oral melanotic macule has previously been described as benign, with no malignant potential. However, a few case reports have raised the question of malignant potential of oral melanotic macule. In this case report, we present a case of coexistence of oral melanotic macule and oral melanoma. A 66-year-old man with a chief complaint of black pigmentation on gingiva showed the lesion spread out on the right palatal gingiva, the right maxillary buccal gingiva and the right buccal mucosa, appearing to merge with one another. Biopsies were performed on the right palatal gingiva and the right buccal mucosa. While the lesion on the right palatal gingiva was diagnosed as an oral melanotic macule, the other lesion on the right buccal mucosa was diagnosed as an oral melanoma. The present case implied the possibility of malignant potential of oral melanotic macule. Therefore, oral melanotic macule needs careful periodic observation for early detection and prompt treatment of the transformed oral melanoma.

  • Malignant Melanoma refers to a malignant neoplasm of melanocytes. Primary malignant melanoma of oral cavity is rare. Most frequent site of primary oral malignant melanoma are palate & gingiva. We have experienced 2 cases of malignant melanoma of the mouth. In one case, we performed wide surgical excision which was followed by chemotherapy with DTIC. In the other case, performed wide surgical excision only. There is no evidence of recurrence or of metastasis of the lesions 22 months, 12 months after operation, respectively.
