Abstract
Nodular hidradenoma is a rare skin adnexal tumor of eccrine differentiation with predominant site being scalp and axillae. Due to its variable locations and unusual clinical presentation and no definite radiological criteria, histopathology seems to be the mainstay in diagnosing these tumors. Most of the lesions present as a cystic swelling and was clinically thought to be a sebaceous cyst/metastasis/carcinoma/sarcoma. In our study, we have included 37 cases and compared its varied clinical and radiological presentation.
