Nodular hidradenoma is a rare benign adnexal tumor that occurs as a solitary nodule with a predilection for the head, face, and upper extremities. We describe the case of nodular hidradenoma presenting as an expanding nodule on the scalp. This tumor is a simulator of malignant lesions on clinical and dermoscopic examination. Our case emphasizes the importance to identify this tumor as a differential for scalp lesions.
