Unilateral galactocele in a male infant
Insights
Galactocele, a rare cause of breast enlargement in male infants, presents as a unilateral cyst. This case highlights the diagnostic and treatment challenges of this uncommon condition in young boys.
Area of Science:
- Pediatric Endocrinology
- Surgical Pathology
Background:
- Galactocele is a rare breast lesion typically seen in lactating women.
- Its occurrence in male infants is exceptionally rare, with limited documented cases.
Observation:
- A 29-month-old boy presented with unilateral, cystic breast enlargement.
- No endocrinologic or other abnormalities were noted.
- Clinical and histopathologic findings were typical for galactocele.
Findings:
- This report details the 27th documented case of galactocele in a male infant.
- The lesion exhibited classic clinical and histopathologic features.
- Etiology is considered multifactorial.
Implications:
- The extreme rarity of galactocele in male infants poses diagnostic and therapeutic challenges.
- Further research into the multifactorial etiology may aid in management strategies.
Introduction:
Galactocele, generally occuring in young women during or after lactation, is an extremely rare cause of breast enlargement in infants and children of exclusively male gender. Only 26 cases have been published so far, including two our cases.
Case Report:
We described unilateral, cystic, breast enlargement, without any endocrinologic and other abnormalities in a 29-month-old boy. A typical clinical and histopathologic presentation of galactocele was followed with a complete excision.
Conclusion:
This was a 27th well documented case of galactocele in a male infant with typical clinical and histopathologic presentation. There are several hypotheses regarding etiology of the lesion, but it is likely to be multifactorial. Because of its extreme rarity, there are some difficulties in differential diagnosis and treatment options of galactocele in male infants.
