Insights
Benign müllerian inclusions, like endocervicosis, are common below the diaphragm but rare above it. This report details an extremely rare case of endocervicosis found in an intramammary lymph node.
Area of Science:
- Gynecologic Pathology
- Surgical Pathology
- Histopathology
Background:
- Benign müllerian inclusions are typically found in infra-diaphragmatic pelvic organs.
- Supra-diaphragmatic occurrences of müllerian inclusions are exceptionally uncommon.
- Endocervicosis, a specific type of müllerian inclusion, is particularly rare outside the pelvic region.
Observation:
- A case of endocervicosis was identified within an intramammary lymph node.
- The patient was a 49-year-old woman.
- This represents the second documented instance of this rare finding.
Findings:
- Histopathological confirmation of benign endocervical tissue within an intramammary lymph node.
- Demonstration of a rare supra-diaphragmatic müllerian inclusion.
- The case highlights the potential for ectopic müllerian tissue in unusual locations.
Implications:
- Expands the known anatomical distribution of benign müllerian inclusions.
- May influence diagnostic considerations for breast lesions in women.
- Underscores the importance of thorough histopathological examination in identifying rare ectopic tissues.
Abstract:
Benign müllerian inclusions are frequently encountered within infra-diaphragmatic locations such as pelvic lymph nodes, bladder, cervix and vagina. Supra-diaphragmatic müllerian inclusions, especially endocervicosis, are exceedingly rare. We report a case of endocervicosis within an intramammary lymph node in a 49-year-old woman. To the best of our knowledge, this is the second reported case.

From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
