Transepidermal elimination (TEE) is a well known phenomenon by which foreign or altered constituents are removed from the dermis. A thrombosis in the dilated dermal blood vessels of angiokeratoma is not unusual, hence the term thrombotic angiokeratoma. We recently reviewed the histopathologic findings of previously diagnosed cases of angiokeratoma and found that multiple histologic sections of surgical biopsy materials disclosed changes indicating TEE of thrombi in three cases. Special stains searching for an altered substance in those thrombi failed. In this report of three cases, we suggest that this phenomenon could be an incidental and long missed histopathologic finding of angiokeratoma which might explain the fate of these thrombi.
