A 61 year-old male patient, diagnosed to have a malignant melanoma in the left arm in April, 1981, was treated by chemotherapy (gamma-INF and DAVP) and a left axillary lymphadenectomy. In March, 1985, he had complained of hoarseness and an early laryngeal squamous cell carcinoma was found, and was subjected to laser treatment. On May 25, 1986, during his hospitalization for treatment of a multiple metastasis of a malignant melanoma, he suddenly suffered from a gastroduodenal perforation. During an emergency operation, a third cancer, a primary mixed hepatocellular and cholangiocellular carcinoma, was discovered.

The life course of acrodermatitis enteropathica is recorded in a 62-year-old white man. Initially saved in infancy by breast-feeding and good medical care, later in his twenties he responded well to diiodohydroxyquinoline (Diodoquin) therapy, his only residua being dermatitis, hoarseness, and short stature. Subsequently untreated, this patient years later developed not only a dermatofibrosarcoma but also a large amelanotic malignant melanoma. Both were successfully excised. Subsequently, oral zinc therapy initiated for the first time cleared his acrodermatitis, which had been present for 60 years. It is suggested that this patient's malignancies developed as a result of an immune deficiency state typically found in acrodermatitis enteropathica. On this basis, acrodermatitis enteropathica may be viewed as having a malignant potential over the long term. The zinc-dependent nature of the immune deficit, however, suggests that lifelong daily zinc supplementation is an appropriate prophylactic measure.

Primary malignant melanoma of the larynx is very rare. The case of larynx malignant melanoma in 71-years old men is presented. Hoarseness was the main complaint that encouraged the patient to visit a doctor. The patient was heavy smoker, he had been smoking 40 cigarettes for the last 50 years. He used to drink about 200 ml of pure alcohol per day. In the direct laryngoscopy gluish had cyanotic tumor, extending to the true vocal cord, ventricle, ventricle fold and subglottic space was seen. Enlarged cervical lymph nodes, laterally to the main vessels were found both in palpation and in US examination. Total laryngectomy and neck dissection was performed. The histological examination of surgical specimen revealed; Malignant melanoma. Metastases in the lymph nodes. Neoplastic infiltration of the nodal capsule. The patient was admitted to the complementary radiotherapy. At the moment the follow up in outpatient. The article contains the review of literature concerning the diagnosis, treatment and prognosis in cases of laryngeal malignant melanoma.

Primary malignant melanoma of the larynx is a rare clinical entity. Only 53 cases have been reported in the medical literature to date. This report describes a case of primary malignant melanoma arising in the larynx and diagnosed by histologic examination of an excisional biopsy specimen. The patient was a 53-year-old man with a history of smoking and hoarseness. There was no clinical evidence of other primary malignant melanocytic lesions. Microscopically, the tumor consisted of polygonal-epithelioid cells admixed with more elongated, spindle-shaped cells. The majority of the cells demonstrated dark brown cytoplasmic and nuclear melanin. Marked pleomorphism and abnormal mitoses were also identified. Despite significant ulceration and disruption of the epithelium, in situ malignant melanocytes were recognized within the remaining portion of the epithelium. Immunohistochemical studies were positive for S100, HMB-45, and vimentin, while cytokeratin and iron stains were negative. Based on the clinical and histologic findings, a diagnosis of primary malignant melanoma of the larynx was established.

Choristoma in the larynx is rare and related to thyroid or glial tissue. The manifestation of salivary gland tissue in the larynx has not been reported to date. We present the case of an 80 year old male complaining of hoarseness and productive coughing. A left side tumourous swelling was seen in the larynx with intact vocal cord mobility. Using microlaryngoscopy the mass was resected without any intra- or postoperative problems. Histologically, a choristoma-heterotopic salivary gland tissue in the muscle and fat tissue--was found. The mucosa was intact and there were no signs of malignancy. Differential diagnosis of such masses in the larynx include benign lesions as well as specific infections, e.g. tuberculosis, sarcoidosis, amyloidosis and Wegener's granulomatosis. Especially in non-smokers, sarcoma, lymphoma and melanoma should be separated from the frequent squamous cell carcinoma of the laryngeal tissue. In rare cases, heterotopic tissue can mimic a tumourous mass. Intralaryngeal resection is the therapy of choice and should be recommended to the patient.

Primary malignant melanoma of the epiglottis is extremely rare. Until now, only 4 cases have been reported in the world literature. We describe a new case of epiglottic primary malignant melanoma in a 74-year-old man who presented with hoarseness and a foreign-body sensation. Clinical examination revealed the presence of a small, whitish, polypoid tumor on the laryngeal surface of the epiglottis; no other primary melanoma was detected. Wide excision of the lesion was performed, and microscopy revealed that it contained melanin-pigmented tumor cells in both the mucosa and submucosa. Immunostaining was positive for S-100 protein. The patient was treated with radiotherapy, and he remained well 1 year after the diagnosis with no evidence of recurrence.

A 56-year-old Japanese man presented with hoarseness and left sided neck swelling in June 2003. Endoscopy showed an irregular tumor extending from the anterior commissure to the left ventricle with dark pigmentation. A biopsy showed malignant melanoma. A total laryngectomy with left radical neck dissection was performed in July 2003, followed by chemohormonal therapy and radiotherapy to the neck. Multiple bone metastases were diagnosed in May 2004, and the patient died with disseminated disease in April 2005, 21 months after initial treatment. The medical literature on laryngeal malignant melanoma was reviewed, and suggested a very poor prognosis despite therapy with surgery, radiotherapy, and chemotherapy.

Tracheal melanomas represent the rarest type of extracutaneous melanomas. The clinical manifestation is similar to other tracheal tumors and ranges from symptoms of airway obstruction such as dyspnea and stridor to other nonspecific symptoms such as hoarseness, cough and hemoptysis. Bronchoscopy is required to draw the origin of the lesion biopsy is needed to establish histologic diagnosis. Treatment consists of either palliative surgery aiming at restoring the airway or tracheal resection and end to end anastmosis. We would like to present here below a rare case of tracheal melanoma and discuss the various diagnostic and therapeutic means.

A 22-year-old man was admitted with complaints of dyspnea and hoarseness. Laryngoscopy and computed tomography of the neck revealed a 1.5 x 2-cm solid mass obstructing the trachea. The black, pedunculated mass was completely removed through a tracheal incision, and a paratracheal lymph node dissection was performed. Histopathologic examination revealed nodular-type mucosal malignant melanoma. Cranial and thoracic computed tomography, abdominal ultrasonography, and histopathologic examination of the paratracheal lymph nodes showed no metastases. No recurrence has been noted in more than 3 years of follow-up.

Multiple myeloma involving the thyroid cartilage is a very uncommon disease entity. Only 10 cases have been reported in the international literature to date and as such it constitutes a rare and challenging diagnosis to make. We report the case of a 63-year-old man with a background of malignant melanoma and multiple myeloma both of which were in remission at the time of presentation. The patient presented with hoarseness and a large neck mass that turned out to be an extramedullary deposit of his previously treated multiple myeloma indicating disease relapse. The differential diagnosis of a mass in the thyroid cartilage is discussed. Despite its rarity, this diagnosis should be considered even in patients with no history of multiple myeloma, as it can arise de-novo in the thyroid cartilage (extramedullary plasmacytoma). The importance of the multidisciplinary team (MDT) approach as well as recent advances in treatment are also discussed.
