title: Desmoplastic malignant melanoma presenting as large lung mass.
abstract: We describe a case of successful minimally invasive thoracoscopic surgical resection of metastatic desmoplastic malignant melanoma replacing the entire right lower lobe of the lung, presenting 4 years after the initial complete resection of the primary scalp lesion. An 89-year-old man presented with a 6-month history of right-sided chest pain. A computed tomographic scan showed a large paravertebral mass with possibility of chest wall invasion. Core biopsy initially raised the suspicion of a schwannoma. We also discussed the atypical delayed presentation and misleading radiologic and histologic findings.
