Abstract:
The subtype of eccrine carcinoma known as squamoid eccrine ductal carcinoma (SEDC) is rare; only 38 cases, including only 6 cases in the ear, have been documented in the literature. This may be the first case to focus on the fact that SEDC, located within the dermal and subcutaneous layers, spares the epidermis histopathologically, which can cause clinicians to confuse SEDC with acute perichondritis.
