Summary
Hidradenoma is an asymptomatic benign sweat gland tumour with apocrine or eccrine differentiation. The most common dermoscopic features are bluish or pinkish homogeneous areas, white structures and vascular structures such as arborizing telangiectasias and polymorphous atypical vessels, mimicking other malignant tumours such as basal cell carcinoma and melanoma. As this tumour is a great masquerader, one should keep in mind hidradenoma in the differential diagnosis, when a blue colour is seen on dermoscopy. Owing to the risk of hidradenocarcinoma development on a pre-existing hidradenoma, the management of this tumour is surgical excision.
