Example 1: A colleague needed a clinical photo of hidradenoma papilliferum
for an upcoming book chapter.
The two apocrine tumours in this study were Hidradenoma papilliferum
and Syringocystadenoma papilliferum.
Hidradenoma papilliferum is a rare, benign adnexal tumor considered to be of apocrine origin that occurs almost exclusively in females on the anogenital area.

INTRODUCTION: Hidradenoma papilliferum is a benign, cystic papillary tumor considered to be of apocrine origin that occurs almost exclusively on the skin of the anogenital region in middle aged females.
Hidradenoma papilliferum was the most common (80 cases; 60%), followed by syringoma (29 cases; 22%), and various types of cysts (12 cases; 10%).
92) Initially thought to be derived from the apocrine glands, (72) subsequent reports suggest hidradenoma papilliferum (and tubular adenoma) to be derived from anogenital mammary like glands.
In our series, hidradenoma papilliferum was the most-common benign vulvar adnexal neoplasm, accounting for 60% of the benign lesions and 42% of the total vulvar adnexal neoplasms (Table 1).
