Abstract:
Background: Lactating adenoses are benign breast tumors that
are usually seen both during pregnancy and lactation period. There is
not yet clear information about the exact pathophysiology and management
of such cases in the literature. We report a case of bilateral complex
growth lactating adenomas which clinically and pathologically mimic
inflammatory breast carcinoma in a 19-year-old lactating woman.
Case Presentation: A 19-year-old female, primigravida presented
3 months after giving birth to a healthy baby, with huge multiple
bilateral breast masses started to grow two years prior to the
presentation (age 17). Clinical assessment, biopsy and
Immunohistochemistry cannot rule out malignancy completely. The main
diagnosis was complex bilateral lactating adenosis. A simple mastectomy
of the left mass with active surveillance of the right mass has been
carried out as a treatment of choice for this case.
Conclusion: Menstruation and pregnancy in young females can be
followed by an aggressive type of lactating adenosis with a complex
macro-histological picture that mimics cancer growth. Moreover, under
the influence of puerperal hormones, bilateral breast involvement can be
inevitable. A simple mastectomy can be treatment of choice for complex
benign lactating adenosis when malignancy cannot be rule out.
