An Apocrine nevus is an extremely rare cutaneous condition that is composed of
apocrine glands.[1]
: 775 Apocrine nevi present as a nodular skin-coloured lump. They are typically asymptomatic. Apocrine nevi can be congenital and they have been associated with other disorders.
Signs and symptoms
Apocrine nevi manifests as a persistent pedunculated or nodular skin-coloured axillary lump.
Causes
Apocrine nevi may be congenital.[9] There have been reported associations with neurofibromatosis,[6] epilepsy,[8] and localized dermal hypoplasia, but these may be coincidental.[10]
Diagnosis
According to histopathology, apocrine nevi are made up of several mature apocrine sweat glands grouped in lobules that invade the dermis and/or hypodermis and cause normal skin structures to be displaced. There may be some cystic dilatation of the lumina in these glands.[11]
