A galactocoele is a benign breast lesion
consisting of a cyst containing thick,
milky fluid with a high fat content, most
commonly seen in a young lactating women.1
A blocked lactiferous duct, generally as a
result of fibrosis from previous infection, is
normally the cause. Patients usually present
with a painless palpable lump in the breast
which is freely mobile. Treatment is complete
aspiration, which is generally successful.
Recurrence is common following successive
pregnancies. We present a young primiparous
woman with a galactocoele caused by an
agenesis or atresia of lactiferous ducts.
Absence of lactiferous duct openings on the
corresponding segment of the nipple and
absence of lactiferous ducts in the
corresponding segment of breast on
Ultrasonography gives evidence for this
inference. An extensive literature search,
including current texts and indexed journal
data revealed no previous reports of such a
case.
