Hidradenoma papilliferum with mixed histopathologic features of
syringocystadenoma papilliferum and anogenital mammary-like glands.

A case of
hidradenoma papilliferum with mixed features of syringocystadenoma
papilliferum (SCAP) and anogenital mammary-like glands is reported. A
single, fresh red-colored nodule developed in the sulcus between the
labia majora and minora of a 49-year-old Japanese woman.
Histopathologically, the tumor showed epithelial lining with apocrine
secretion and slight connective tissues characteristics. Our case was
unique because, like SCAP, the tumor was connected to the epidermis
and cystic invaginations extended downward into the deep dermis. In
addition, beneath the tumor, tubular structures that resembled normal
mammary tissue were present in the subcutaneous fatty tissue. In this
study, it has been suggested that this tumor might have been developed
from these mammary-like glands. |
