Three cases of primary adenocarcinoma of the Fallopian tube have been treated at the Gynecology Department of Hospital A. C. Camargo, Fundación A. Prudente, São Paulo, between 1972-1987. The diagnosis was only possible at surgery. The poor prognosis was due to the advanced stage of the disease. In view of its rarity further studies are necessary for a better diagnostic and therapeutic approach.
The morphology of the pars intramuralis of the fallopian tube has been histological examined in 500 uteri which were exstirpated in the Department of Gynaecology and Obstetrics of the University of Kiel in the years of 1972 to 1973. It was found that the interstitial pars of the endometrium changes regularly during the menstrual cycle. In the same way the endometrium in the interstitial part of the tubal canal suffers from an atrophy if patients were treated with gestagens. The adenomatous hyperplasie or the polypes of the endometrium which are often found near the utero-tubal junction are to be considered as the matrix of the carcinoma of the endometrium; continuous changes between the adenomatous hyperplasie and the carcinoma of the endometrium can be observed. The frequency of precancers near the utero-tubal junction underlines the demand for an accurate curettage in this region of the cavum uteri. The histological examination of the region of the utero-tubal junction after the extirpation of the uterus is absolutely necessary and has to be generally to be asked for.

Microsurgical operations of sterility on 39 women with only one remaining tube have been analysed in order to examine the justification of primary operations of sterility on these patients. 13 out of 26 women (50%), who had been followed up for at least 9 months after the operation, have become pregnant. Live birth rate was 30.8% abortion rate 7.7% and the rate of ectopic pregnancies 11.5%. The results correspond to these obtained from women bilaterally operated on, so that microsurgical operations are justified in sterile women with a lacking opposite tube, too. The removal of the opposite tube during the actual operation of sterility is prognostically more advantageous than the exstirpation before it. Salpingectomy has better results than salpingo-oophorectomy.
42 of 86 patients with suppurated ovaries had primary isolated ovarian abscesses (PIOA), 44 secondary tubo-ovarian abscesses (STOA). Parts of ectopic endometrium in the abscess wall could be identified by serial sections in 23 PIOA. With Berlin-blue-staining was a special phenomenon in 28 of 42 PIOA demonstrated: a basal layer of hemosiderophages underlying the abscess membrane. Thus in 36 of 42 PIOA the histogenesis out of cystic ovarian endometriosis or other pathologic ovarian hematomas is assured. The PIOA is a typical major complication of ovarian hematomas, especially in cases of ovarian endometriosis caused by vaginal aplasia (gynatresia). Concomitant salpingitis in PIOA is therefore often better explained as secondary descending infection from pelveoperitonitis. Before laparotomy it is extremely difficult to diagnose PIOA on a clinical basis only. More than laboratory data helps this special consideration if an inflammatory adnexal mass could be or not the result of an ascending infection and if an ovarian endometriosis could exist. Besides the abscesses out of cystic ovarian endometriosis PIOA were observed after hysterectomies and complicated appendectomies possible due to the infection of traumatic ovarian hematomas. The only curative therapy for PIOA is surgery--as soon as possible. Antibiotics are poorly helpful. However the inefficacy of antibiotics usually gives the final indication for laparotomy. Knowing the usual etiology of PIOA out of pathologic (endometriotic) ovarian hematomas we have new guidelines in other clinical problems also: Thus every ovarian endometriosis has to be cured--hormonally or surgically; evacuation of endometriotic cysts during pelvic endoscopy is not a sufficient therapy, for the endometrium would be left in the ovary. During operations provocation of traumatic hematomas of the adnexa should be avoided.
Two asymptomatic cases of adenomatoid tumor, confined to the lamina propria of the tubal fimbria, are presented, and their location within strictly Müllerian territory is offered as indirect evidence for the Müllerian origin of this lesion. To stress the individuality of this distinct entity, the name of Müllerian mesothelioma is suggested.
Microscopic evaluation of a human fallopian tube following end-to-end anastomosis over a polyethylene stent was performed 10 days after the initial surgical procedure. The stent was removed on the 3rd postoperative day. Examination of the excised tube revealed a patent lumen without any evidence of mucosal compromise. The submucosa adjacent to the anastomotic site revealed a mild polymorphonuclear leukocytic infiltration, although a marked inflammatory response was observed around the 5-0 chromic sutures used in the reanastomosis. This case and recent animal studies suggest that early removal of the stent does not appear to jeopardize the patency of the tube and may be preferable to removal after 3 to 4 months.
A patient with co-existent carcinoma and tuberculosis of the Fallopian tube is described. Tuberculosis was diagnosed by the finding of numerous typical granulomata throughout the uterus, tubes and ovaries, and by exclusion of other possible causes of these; and carcinoma by the finding of solid tumour, with a marked anisocytic appearance, invading submucosa. Despite the well recognised epithelial hyperplasia seen in tuberculous salpingitis, there remains no evidence that the occurrence of carcinoma in such cases is other than fortuitous.
A case of primary carcinoma of the fallopian tube with coexistent tuberculosis has been presented, and previously reported cases in the literature reviewed. These cases represent a rare occurrence where the diagnosis might be missed without a thorough pathologic evaluation. Clinicians should maintain an index of suspicion for fallopian tube carcinoma in perimenopausal or postmenopausal women with menometrorrhagia who fail to respond to hormonal therapy and a D and C. The finding of a tuboovarian abscess in a postmenopausal woman should also cause concern for tubal carcinoma, as it is usually a disease of menarcheal women. Similarly, a possibility of granulomatous salpingitis should always be borne in mind in the differential diagnosis of inflammatory diseases of the fallopian tube.
Proliferative epithelial lesions of the oviduct have been called adenomatous hyperplasia or carcinoma in situ. In order to assess the incidence and significance of these lesions, we sectioned entire oviducts from 124 nonselected hysterectomies. We found 23 cases (18.5%) with lesions corresponding to those described in the literature. We have found no justification for diagnosing and treating these lesions as carcinoma in situ. There appears to be an association with salpingitis.

Nodular salpingitis and tubal endometriosis have been referred to in succession as salpingiosis, diverticulosis, adenomyosis of the oviduct, endometrioid conditions, etc. This varied terminology underscores their etiopathogenetic and morphological substratum which is different from that of non specific tubal inflammation, but at the same time this variety of terms has always created confusion in interpretation and diagnosis. We have considered it necessary to carry out a comparative study of nodular salpingitis and tubal endometriosis in 42 cases of sterility operated during the last two years for tubal obstruction and in which histological examination has yielded evidence for the lesions of nodular salpingitis (NS) or endometriosis (EM) in at least one of the oviducts. As for the etiology of the two diseases, we have discussed the role plaid by inflammatory conditions, uterine trauma (curettage) and dystrophic disorders, as well as the importance of hyperandrogenism in NS. Taking into account the diffuse sclerogenic tendency of the tubal wall in NS and the concomitant inflammatory and dystrophic lesions in the peritubal tissues in EM, the postoperative outlook depends on early surgery, to be performed before tubal anatomy has been completely altered.
