RESUMO
BACKGROUND: Amelanotic lentigo maligna is not clinically suspected and is often mistaken for a basal cell carcinoma, squamous cell carcinoma, or dermatitis. OBJECTIVE: Our objective was to review previously reported cases of amelanotic lentigo maligna and compare them with our 3 cases. METHODS: The clinical presentation and histologic findings of 3 new cases are described and compared with those in the literature. RESULTS: The index of suspicion for amelanotic lentigo maligna is extremely low. No reported cases have been diagnosed clinically. None of our 3 cases was suspected. LIMITATIONS: Only three cases were reviewed. CONCLUSION: A high degree of clinical and histologic suspicion is required to make the diagnosis of this clinically nondescript neoplasm.
