An Apocrine nevus is an extremely rare cutaneous condition that is composed of hyperplastic mature 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

[edit]

Apocrine nevi manifests as a persistent pedunculated or nodular skin-coloured axillary lump.[2] Additionally, reports of them occurring on the face,[3][4] scalp,[5] chest,[6] and inguinal area have been made.[7] The majority of the time, apocrine nevi are asymptomatic, although some individuals describe minor pain, baldness, or in rare cases, leakage.[8][9]

Causes

[edit]

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

[edit]

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]
