Two cases of esophageal primary melanoma in females aged 63 and 68 years with nodular and lentiginous forms of growth are reported. The diagnosis was made intraoperatively and at autopsy, respectively. Morphogenetically, there were primary multiple non-simultaneous zones of tumor growth with the apposition growth as a form of tumor progression. Early stages of morphogenesis were characterized by atypical borderline melanocytic activity, melanoma in situ with a starting invasive growth being basic criteria for diagnosis of primary esophageal melanoma in examination of endoscopic and surgical material.
