Abstract
Cellular neurothekeomas (CNTs) are rare, benign cutaneous tumors that arise primarily on the head and neck, with a slight female predominance. CNTs with atypical features have been described, including those with an infiltrative growth pattern. Although CNTs with atypical features are benign, recognition of this entity can pose diagnostic challenges. Here, we report a case of CNT with an unusual clinical presentation on the left second digit, and with atypical histological features including an infiltrative growth pattern, which could have been mistaken for features of malignancy.
