Peritoneal epithelial lesions associated with proliferative serous tumours of ovary

Abstract

The peritoneal epithelial lesions in 40 cases of proliferating ovarian serous tumour are described. The lesions were varied and of both neoplastic and non-neoplastic form. The most common was serous tumour similar to that in the associated ovarian neoplasm. Tumour of this type was present in some or all of the peritoneal lesions in 77.5% of cases. In nearly two-thirds, the tumour was superficial; in the rest it invaded omentum. Occasionally, the infiltrating tumour was poorly differentiated. Benign tubular lesions resembling endosalpingiosis occurred in 16 (40%) of the 40 cases, but in seven it was associated with serous tumour. Psammoma bodies frequently accompanied serous tumour and endosalpingiosis and in occasional cases the majority of lesions consisted of psammomatous foci. The duration of follow up is too short to adequately assess the biological significance of these findings but it is clear that the peritoneal tumour occasionally may kill the patient within a few years. 'Serous tumour of low malignant potential' is the most appropriate term to describe the general group of ovarian serous tumours of so-called 'borderline malignant' type.

Serous ovarian tumors of low malignant potential with peritoneal implants

“…Spontaneous regression of metastatic implants has also been reported.l6,I7 Some authors have classified implants as either noninvasive or invasive8~'s-22 and have attempted to correlate the type of metastatic implants with prognosis. [19][20][21][22] In an effort to understand better the biologic behavior of serous ovarian tumors of LMP with peritoneal implants and to devise a rational treatment approach, we reviewed our experience with this tumor at The University of Texas M. D. Anderson Cancer Center, Houston.…”

Chemotherapy of borderline ovarian tumors

“…Cependant, il n'existe pas de preuve que l'aneuploïdie soit un facteur de risque indépendant. L'impact des caracté-ristiques des implants péritonéaux (invasifs ou non) a également été discuté [4,39,40,44], mais actuellement la majorité des équipes s'accorde pour leur attribuer un impact péjoratif ; -les TOLM séreuses avec composante micropapillaire sont fréquemment associées à des extensions extra-ovariennes, souvent à type d'implants péritonéaux invasifs. Le pronostic de ces tumeurs est identique, à extension tumorale similaire, à celui des TOLM séreu-ses sans composante micropapillaire [24,50].…”

Endosalpingiosis, an unrecognized condition: report and literature review

“…2 Histopathology of endosalpingiosis and endometriosis several reported cases in which endosalpingiosis has created diagnostic problems, particularly when the cytologist is unaware of the morphology of the primary tumour [16,17,15]. As previously mentioned, endosalpingiosis may be associated with ovarian epithelial neoplasms, especially borderline or welldifferentiated lesions [19,20,21]. It has also been found in association with cervical carcinoma [16,17].…”

“…Macroscopically, this disease is usually not discernable. When it is visually obvious, endosalpingiosis can be seen as multiple white to yellow, translucent to opaque, punctate, fluid-filled cystic lesions [20].…”
