BACKGROUND
Keloids generally present in a recognizable fashion, atypical locations may closely resemble other dermatologic conditions. Cutaneous sarcoidosis in particular can manifest as firm, infiltrated papules or plaques on the face and may mimic keloids both clinically and, in certain variants, histologically.
Keloids involving the nasal tip are exceedingly rare. To date, solitary keloids confined to the nasal tip have not been reported in the literature, making such cases diagnostically challenging and clinically notable. We describe an unusual instance of a nasal-tip keloid initially suggestive of cutaneous sarcoidosis, ultimately requiring histopathological confirmation for accurate diagnosis.
CONCLUSION
To our knowledge, this case represents the first reported instance of a nasal-tip keloid clinically mimicking cutaneous sarcoidosis. Its unusual localization and misleading appearance highlight the diagnostic difficulty associated with atypical keloids and demonstrate the crucial role of histopathology when clinical features are inconclusive. Accurate diagnosis helps avoid unnecessary systemic investigations and guides appropriate treatment in these rare and deceptive presentations.
