A 56-year-old Caucasian woman presented with a lesion on the right ear of 5-year duration. The site had undergone incision and drainage with no expression of contents followed by a complete excisional punch biopsy 4 years prior to presentation. The patient now presented with recurrence of the lesion, which she reported had been growing in size. Despite its growth, the lesion remained asymptomatic. Physical examination revealed a dermal nodule with a bluish hue and visible telangiectasias on the root of right ear, measuring 1.7 cm in size [Figure 1]. Histopathologic evaluation of a biopsy revealed a dermal-based, well-circumscribed lobulated tumor island composed of basophilic cells with little cytoplasm [Figure 2]a. Higher magnification showed two types of tumor cells – small, dark basaloid cells with scant cytoplasm and small nuclei and slightly larger cells with a more open nuclear chromatin pattern [Figure 2]b. The larger cells surrounded areas of focal ductal differentiation. No atypical features were identified.
