Delay in diagnosis of acral melanoma.
We report a 41-year-old woman presented with a 4-year history of an exuberant, erythematous tumor, with necrotic appearance of the right distal toe. The histopathology examination showed a nodular-ulcerative melanoma, with bone infiltration. Widespread metastases including the right ovary, peritoneum, and right breast were present. The patient was misdiagnosed for almost 4 years as having onychomycosis, ingrown nail and pyogenic granuloma.
