  • Malignant melanoma of the nasal cavity occurs rarely. Malignant melanoma, originated from the upper respiratory tract including nasal cavity, has clinical feature of local recurrence and easily metastasizes to regional or distant lymph nodes, lung, and liver. Malignant melanoma originated from nasal cavity frequently shows tumor cell invasion, ulceration, or infection. Owing to these characteristics, complete surgical excision of the malignant melanoma in nasal cavity is not easy. And also the prognosis of this tumor is not so good because of a high recurrence rate. Recently the authors have recently experienced a case of malignant melanoma originated from the inferior turbinate, which was treated with lateral rhinectomy, total maxillectomy. The defect developed after surgical extirpation was reconstructed with rotational forehead flap.

  • A neutered male, 8-year-old, Pekingese, weighing 4.3 kg with a history of anorexia, sneezing, nasal discharge, and epistaxis for one month was referred. Soft tissue swelling around the nasal bone and small defects of the hard palate with a tiny round dark red mass were found on physical examination. The laboratory tests represented mild leukocytosis. On skull radiographs, soft tissue swelling and osteolytic change of the incisor bone, nasal bone, and maxilla were found. On computed tomography scan images, there was soft tissue attenuating opacity with calcified spots in the bilateral nasal cavities and frontal sinuses. Loss of nasal turbinate pattern and nasal septum was found. And destruction of the insicor bone, nasal bone, maxilla, hard palate, perpendicular palatine bone, and cribriform plate were identified. Nasal malignant melanoma was confirmed by nasal biopsy.

  • 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.

  • Melanoma can occur as a metastasis within subcutaneous tissue, lymph nodes, or viscera without a detectable primary tumor. Among patients with metastatic melanoma of unknown primary lesion, those with endobronchial metastasis are exceedingly rare. Herein we report a case of an endobronchial and pulmonary metastasis in a patient with melanoma originating from an unknown primary site. The patient without a previous history of melanoma presented with blood-tinged sputum. Fiberoptic bronchoscopy revealed a black polypoid tumor obstructing the posterior basal segmental bronchus of the right lower lobe. A final diagnosis of the malignant melanoma was made based on an immunohistochemical study of the bronchoscopic biopsy specimen. Skin, ophthalmic, oral, and nasal examinations failed to identify occult primary lesions. Subsequent evaluation including positron emission tomography/computed tomography scans did not uncover any abnormalities other than the metastatic pulmonary melanoma. We also describe the characteristic bronchoscopic features of melanoma.

  • Magnoliae Flos(‘shin-j’). the flower buds of Magnolia kobus, is acrid to taste with a ‘warm’ property. It is a ‘wind-cold’ discutient and nasal decongestant and is principally used in the treatment of nasal congestion with headache, sinusitis and allergic rhinitis. By screening inhibitory activities on the melanin polymer biosysthesis in B-16 mouse melanoma cell lines, methylene chloride extract of Magnoliae Flos was found to have inhibitory effect on melanin polymer biosynthesis.

  • Sinonasal mucosal melanoma (SNMM) in the maxillary sinus is a rare disease condition. Compared to oral mucosal melanoma, SNMM has a bulky, exophytic, and polypoid appearance, is weakly pigmented, and associated with unspecific symptoms. Due to these features, SNMM in the maxillary sinus has been misdiagnosed as nasal polyps and chronic sinusitis. In this case report, we described SNMM occurring in the right maxillary sinus simulated as a cystic or benign lesion. Cortical bone thinning and expansion were observed around the mass. The excised soft mass was encapsulated and weakly pigmented. The mass was clearly excised and covered with a pedicled buccal fat pad graft. Diagnosis using immunohistochemistry with S-100 and homatropine methylbromide-45 (HMB-45) is critical for proper treatment.

  • Metastasis to the thyroid gland is very rare in clinical practice. We recently encountered a 65-year-old woman who presented with a large thyroid nodule that mimicked the cytologic features of a papillary thyroid carcinoma on fine needle aspiration biopsy (FNAB). Although initially diagnosed as a papillary thyroid carcinoma, a thorough clinical work-up revealed multiple lesions in the bones, liver, and nasal cavity, which were confirmed as metastases of a malignant melanoma. Despite a thorough physical examination, however, the primary skin lesion could not be identified. Although FNAB shows a high degree of accuracy in diagnosing primary thyroid tumors, it is less accurate in diagnosing metastases to the thyroid gland. A thorough clinical history with appropriate immunohistochemical staining assays is necessary for the accurate diagnosis of metastatic malignant melanoma.

  • Background Nasal reconstruction is one of the most difficult challenges for the head and neck surgeon, especially in the case of complex full thickness defects following malignant skin tumor resection. Full-thickness defects require demanding multi-step reconstruction. Methods Seven patients underwent surgical reconstruction of full-thickness nasal defects with a bi-pedicled forehead flap shaped appropriately to the defect. Patients were aged between 58 and 86 years, with a mean age of 63.4 years. All of the tumors were excised using traditional surgery, and in 4 of the patients, reconstruction was performed simultaneously following negativity of fresh frozen sections of the margins under general anesthesia. Results Nasal reconstruction was well accepted by all of the patients suffering non-melanoma skin tumors with acceptable cosmetic outcomes. The heart-shaped forehead flap was harvested in cases of subtotal involvement of the nasal pyramid, while smaller defects were reconstructed with a wing-shaped flap. No cartilaginous or osseous support was necessary. Conclusions This bi-pedicled forehead flap was a valid, versatile, and easy-to-implement alternative to microsurgery or multi-step reconstruction. The flap is the best indication for full-thickness nasal defects but can also be indicated for other complex facial defects in the orbital (exenteratio orbitae), zygomatic, and cheek area, for which the availability of a flap equipped with two thick and hairless lobes can be a valuable resource.

  • 점막형 악성흑색종 10례에 대한 임상분석 결과 비강에서 가장 호발하였고 증상은 비폐색이 가장 많았다. 치료 성적은 수술을 우선적으로 선택한 후 방사선요법을 시행한 경우군에서 평균생존기간이 20.8개월이었고 방사선치료를 우선적으로 선택한 경우군에서는 14.7개월로, 접막형 악성흑색종의 경우 광범위 절제술 후 방사선요법을 시행하는 것이 도움이 될 것으로 생각되나 윈격전이 6례를 포함한 8례의 환자에서 재발이 있어 예후가 극히 불량한 암종으로 생각된다.
