“…The absence of a primary or simultaneous ovarian serous‐type lesion would discard the notion of a benign serous implant. However, in one of the reported cases of supradiaphragmatic ES (9), the patient developed a low grade papillary serous carcinoma of the ovary 3 years after the diagnosis of axillary ES.…”

“…Outside the abdomen, only five cases of supradiaphragmatic ES have been described in intramammary, (8,9) and axillary lymph nodes (5–7). However, to the best of our knowledge, this is the first case of FPE reported in a supradiaphragmatic location.…”

“…Glandular inclusions were isolated and identified within the subcapsular, marginal sinus. Histology revealed cysts lined by a nonciliated serous‐type epithelium (9). In two cases (8,9), solitary, nonbranching pseudopapillary protrusions without fibrovascular cores were present; psammoma bodies were noted in both.…”

“…Unusually, ES can occur outside the abdominal area, with five cases, none of which corresponded to florid type, reported in supradiaphragmatic locations in both axillary (5–7), and intramammary lymph nodes (8,9).…”

Florid, Papillary Endosalpingiosis of the Axillary Lymph Nodes

A 55-year-old woman underwent radical mastectomy and axillary node dissection because of an invasive ductal carcinoma with neuroendocrine features. Histologically, all 22 sampled lymph nodes had widespread cystic inclusions lined by a regular, serous-type epithelium positive for cytokeratin-7, WT-1, CA125, and estrogen receptors. Papillary projections were found in the lumen of some cysts. The lesions were consistent with florid, papillary endosalpingiosis (FPE), a hitherto unreported condition in a supradiaphragmatic location. Metastases from papillary carcinomas of ovary, breast, or thyroid were excluded considering the lesion's immunophenotype (negative for mammaglobin and TTF-1) and the absence of both atypical features and a concurrent abdominal serous tumor. In only one node, lesions co-existed with a metastasis of breast carcinoma. Supradiaphragmatic FPE represents a pitfall in the differential diagnosis of metastases, especially in sentinel nodes, since it may increase their size and reveal an unusual ultrasonographic image. Clinicopathologic findings and a focused immunohistochemical study led to the correct diagnosis of this benign lesion.

Epithelium Involving Bilateral Axillary Lymph Nodes: Metastasis, Misplaced, or Mullerian!

et al. 2020

View full text Add to dashboard Cite

During breast cancer staging, histological evaluation of axillary sentinel lymph nodes (SLN) is usually straightforward. However, the exact characterization of a small epithelial deposit in an SLN can be challenging, especially during the frozen section examination. We report the first case of endosalpingiosis involving bilateral axillary lymph nodes. We review published literature on axillary endosalpingiosis and discuss the differential diagnosis of small epithelial deposits in an axillary SLN. Pathologists should consider benign epithelial rests and displaced epithelium as differential diagnoses for the microscopic epithelial nodal deposit, especially during the frozen section examination.
