Nodular hidradenoma in a 19-year-old woman

Hidradenomas are rare adnexal tumors. Recently, two groups have been individualized: those with eccrine differentiation called poroid hidradenoma and those with apocrine differentiation called clear-cell hidradenoma or nodular hidradenoma. Herein we report a case of 19-year old woman with a nodular hidradenoma of the scapular region. Our report highlights the clinic-pathological characteristics of these tumors and emphasizes the benefit of complete local excision to prevent risk of recurrence and possible malignant potential.
