- Early symptoms can mimic benign conditions like gout, delaying diagnosis.
Observation:
- A 61-year-old male presented with a persistent great toe lesion previously treated for gout.
- Histopathological examination revealed nests of atypical tumor cells.
Findings:
- The patient was diagnosed with amelanotic malignant melanoma of the subungual region.
- The condition was initially misdiagnosed as gout, leading to delayed treatment.
Implications:
- This case highlights the importance of considering rare diagnoses in persistent lesions.
- Timely and accurate histopathological diagnosis is critical for improving prognosis in subungual amelanotic melanoma.
