29) For peritoneal resection specimens, additional findings, such as endometriosis, endosalpingiosis
, and mesothelial inclusion cysts, should be noted.
The morphological differential diagnosis had to be done with ovarian endosalpingiosis
, a lesion frequently overdiagnosed as endometriosis, due to histological resemblance, and ovarian serous cystic lesions, while colon location has been differentiated from colon carcinoma and lymph nodes from cystic lesions, all these being excluded by characteristic histology.
El aspecto mas relevante del TA es su diagnostico diferencial, que en utero incluye adenocarcinoma endometrial o metastatico y linfangioma, mientras en ovario debe hacerse con tumores epiteliales serosos, endosalpingiosis
, tumor de seno endodermico, metastasis y tumores del estroma gonadal para la variante oxifilica.
1%) tenian miomatosis, 1 (3%) con diagnostico histologico de endosalpingiosis
y en 1 (3%) no se encontro alteracion patologica.
Florid endosalpingiosis rarely may enter in the differential diagnosis of minimal deviation endometrioid adenocarcinoma owing to the randomly distributed glands with irregular contours (complex infolding and branching), marked variation in gland size and shape, and occasional nuclear pseudostratification 205 Helpful features in favor of florid endosalpingiosis include: (1) tubal-type epithelium with no more than mild atypia; (2) absence of mitotic activity; and (3) unremarkable stroma.
Florid cystic endosalpingiosis with tumor-like manifestations: a report of four cases including the first reported cases of transmural endosalpingiosis of the uterus.
The cytologic appearance of tubal-type epithelium in urinary cytology may be inferred from a report of endosalpingiosis of the urinary bladder.
Though the differential diagnosis toward low-grade urothelial carcinoma may be more complex, (22,23) the evidence of macrophages, which are found in endosalpingiosis, supports the hypothesis of mtillerianosis.
often occurs with either endometriosis or endocervicosis, although any combination of these 3 can be seen, warranting the term mullerianosis, when substantial amounts of each are present.
Additionally, benign conditions such as endosalpingiosis
may be extremely difficult to differentiate from borderline ovarian tumors (tumors of low malignant potential) or low-grade serous carcinomas in cytologic specimens.
To present a brief history of this condition and describe its distinctive histology and clinical presentation, as well as to review the chief differential diagnostic considerations, to include mesothelial proliferations, endosalpingiosis
, endometriosis, high-grade primary peritoneal papillary serous carcinoma, and implants from primary ovarian serous neoplasms.
Additional pathologic findings (eg, endosalpingiosis
and relation to tumor, if pertinent) 3.
