[Melanoma bronchopulmonary metastasis concerning 2 cases]

ABSTRACT

Melanoma is a malignant melanocytary tumor that has a great metastatic potential. Bronchopulmonary metastases are the most frequent ; estimated up to 33% according to the review of literature. The authors report two observations of melanoma bronchopulmonary metastases. The first observation concerns a 61 year-old patient, with as antecedent a melanoma of the thigh confirmed by exersis biopsy and who shows two years later a bronchic syndrome with thoracic pain in a context of general condition alteration. Chest x-ray revealed a retractile opacity of all the right hemithorax associated to a left mediothoracic macronodular opacity. Bronchoscopy detected a tumor obstructing the right bronchus strain whose anatomopathologic exam concluded to a bronchic melanoma. The diagnosis of the melanoma bronchopulmonary metastases of the thigh was thus maintained and the proposed treatment was palliative symptomatic. The second observation concerns a 42 years patient who showed 1 month before had admittance to hospital a bronchic syndrome and thoracic pain in a context of general condition alteration with a naevus of the right cheek of 3 cm in an ulcerous detected a stage melanoma. The chest x-ray found multiple macronodular opacities in baloon-letting out form of tissular density at CT-scan evoking pulmonary metastases. Bronchoscopy revealed a burgeoning tumor witely necrosed at the left basal pyramid. The diagnosis of melanoma bronchopulmonary melanoma of the cheek was maintained and the treatment was symptomatic
