Delayed involution of lactation presenting as a non-resolving breast mass: a case report.
BACKGROUND
Involution of lactation is a physiological process. Rarely, it may be delayed and troublesome for the lactating woman. Though lactation-induced changes in breast are well known, morphological features of delayed involution are not clear.


METHODS
We report a case of a 22-year-old lactating mother who presented with a painful, non-resolving breast mass 5 months after delivery. Clinically, it simulated an inflammatory carcinoma. Histopathology, however, revealed involuting lactational changes.


CONCLUSIONS
To the best of our knowledge, lactational involution with such a presentation has not been described in the English literature. The case needs to be reported so that this entity can be considered among the differential diagnoses of breast masses in a lactating patient.
