Demographic, clinical, and service-use characteristics related to the clinician's recommendation to transition from child to adult mental health services.

PURPOSE: The service configuration with distinct child and adolescent mental health services (CAMHS) and adult mental health services (AMHS) may be a barrier to continuity of care. Because of a lack of transition policy, CAMHS clinicians have to decide whether and when a young person should transition to AMHS. This study describes which characteristics are associated with the clinicians' advice to continue treatment at AMHS. METHODS: Demographic, family, clinical, treatment, and service-use characteristics of the MILESTONE cohort of 763 young people from 39 CAMHS in Europe were assessed using multi-informant and standardized assessment tools. Logistic mixed models were fitted to assess the relationship between these characteristics and clinicians' transition recommendations. RESULTS: Young people with higher clinician-rated severity of psychopathology scores, with self- and parent-reported need for ongoing treatment, with lower everyday functional skills and without self-reported psychotic experiences were more likely to be recommended to continue treatment. Among those who had been recommended to continue treatment, young people who used psychotropic medication, who had been in CAMHS for more than a year, and for whom appropriate AMHS were available were more likely to be recommended to continue treatment at AMHS. Young people whose parents indicated a need for ongoing treatment were more likely to be recommended to stay in CAMHS. CONCLUSION: Although the decision regarding continuity of treatment was mostly determined by a small set of clinical characteristics, the recommendation to continue treatment at AMHS was mostly affected by service-use related characteristics, such as the availability of appropriate services.

Pro-inflammatory mediators in vaginal fluid and short cervical length in pregnancy.

AIM: We hypothesized that elevated vaginal levels of matrix metalloproteinase-8 (MMP-8), interleukin-8 (IL-8) and the 70kDa heat shock protein (hsp70), compounds involved in inflammatory responses, correlated with a short cervix in pregnant women. METHODS: This prospective cohort study used a convenience sample of 64 women in their early third trimester with a singleton pregnancy. A short cervical length was present in 35 women (54.7 %). Vaginal fluid was tested for levels of MMP-8, IL-8 and hsp70 by enzyme-linked immunosorbent assay (ELISA). A receiver operating charasteristic (ROC) analysis was used to calculate the area under the curve (AUC) for each mediator in predicting short cervical length. RESULTS: MMP-8 (109 vs 29.6 ng/ml, p=0.014), IL-8 (689 vs 330 pg/ml, p=0.007) and hsp70 (4.4 vs 2.9 ng/ml, p=0.036) were all elevated in vaginal samples from women with a short cervix. In addition, there was a negative association between the concentration of each compound in vaginal fluid and cervical length p≤0.026). The vaginal IL-8 concentration had the highest negative correlation with a short cervix (AUC=0.7, p=0.007). CONCLUSION: MMP-8, hsp70 and IL-8 contribute to a pro-inflammatory cervico-vaginal milieu that weakens cervical integrity and leads to a shortening in cervical length (Tab. 4, Fig. 1, Ref. 27).

What is the evidence for the role of TRP channels in inflammatory and immune cells?

A complex network of many interacting mechanisms orchestrates immune and inflammatory responses. Among these, the cation channels of the transient receptor potential (TRP) family expressed by resident tissue cells, inflammatory and immune cells and distinct subsets of primary sensory neurons, have emerged as a novel and interrelated system to detect and respond to harmful agents. TRP channels, by means of their direct effect on the intracellular levels of cations and/or through the indirect modulation of a large series of intracellular pathways, orchestrate a range of cellular processes, such as cytokine production, cell differentiation and cytotoxicity. The contribution of TRP channels to the transition of inflammation and immune responses from a defensive early response to a chronic and pathological condition is also emerging as a possible underlying mechanism in various diseases. This review discusses the roles of TRP channels in inflammatory and immune cell function and provides an overview of the effects of inflammatory and immune TRP channels on the pathogenesis of human diseases.

Sulci of the liver found after death: Their nature and potential teaching value.

Accessory sulci of the liver are more commonly found after death than in life, raising questions as to their causation and possible classification. We have analyzed a group of 180 livers sampled from un-embalmed (96) and embalmed cadavers (84). In un-embalmed cadavers, no accessory sulci were found on the diaphragmatic surface in 58 cases. Diaphragmatic sulci were found in the right lobe of 38 livers. When removed from the abdominal cavity and placed flat on the examination table (the "bench position") all 58 livers without sulci appreciable in the abdominal cavity showed the appearance of two sulci. The first ran from the right side of the inferior vena cava (IVC), curving anteriorly to the inferior border of the liver, at a point midway between the right extremity of the inferior border and the gallbladder fossa, concave towards the left. The second sulcus ran from the left side of the IVC, curving anteriorly to reach the inferior border of the liver at the level of the gallbladder fossa, concave towards the right. With progressive side-to-side manual compression, the sulci on the diaphragmatic surface become more evident. Division of the hepatic parenchyma along the two sulci exposed the right and middle hepatic veins respectively in more than 90% of cases. In embalmed cadavers, 24 livers showed antero-posterior sulci in the superior surface, visible and palpable on the liver examined in situ. When the livers with sulci had been removed from the abdomen for further examination, the appearance of the superior surface did not change. In a removed liver, accessory sulci can be divided into true, "diaphragmatic," sulci and "false" sulci due to the position of the free liver on the examination table. The "false" sulci may be considered as further morphological evidence of the functional anatomical division of the liver. Their demonstration may also be useful in teaching its topographical and surgical anatomy.

Knee Region Coverage with Reversed Gracilis Pedicle Flap (GReSP Flap).

INTRODUCTION: To treat severe soft-tissue complications of total knee arthroplasty, we used an extended reversed gracilis flap based on secondary pedicles (the GReSP flap). STEP 1 PREPARE WOUND BED: Locate the gracilis and pedicles, then debride the wound bed. STEP 2 EXPOSE GRACILIS MUSCLE: Expose the superficial aspect of the muscle, while protecting the saphenous vein and nerve. STEP 3 CHECK MUSCLE PERFUSION: Temporarily clamp the main vascular pedicle to ensure blood supply when perfused only by the secondary pedicles. STEP 4 MOBILIZE MUSCLE FLAP: Transect the proximal tendon of the gracilis muscle to provide maximal length for the muscle flap and ligate the main vascular and nerve pedicles. STEP 5 COVER WITH SKIN GRAFT: Suture the flap in place and cover with skin graft. STEP 6 POSTOPERATIVE CARE: Immobilize the knee for two weeks; follow with rehabilitation to restore range of motion. RESULTS & PREOP/POSTOP IMAGES: We treated three patients who had an infection at the site of a total knee arthroplasty and exposure of the implant.

Neurotensin receptor 1 immunoreactivity in the peripheral ganglia and carotid body.

In the present study we investigated, through immunohistochemistry, the presence and location of neurotensin receptor 1 (NTR1) in the peripheral ganglia and carotid body of 16 humans and 5 rats. In both humans and rats, NTR1 immunostained ganglion cells were found in superior cervical ganglia (57.4+/-11.6% and 72.4+/-11.4%, respectively, p0.05), enteric ganglia (51.9+/-10.4% and 64.6+/-6.1, p<0.05), sensory ganglia (69.2+/-10.7% and 73.0+/-13.1%, p>0.05) and parasympathetic ganglia (52.1+/-14.1% and 59.4+/-14.0%, p>0.05), supporting a modulatory role for NT in these ganglia. Positivity was also detected in 45.6+/-9.2% and 50.8+/-6.8% of human and rat type I glomic cells, respectively, whereas type II cells were negative. Our findings suggest that NT produced by type I cells acts in an autocrine or paracrine way on the same cell type, playing a modulatory role on chemoception.

Chronic carotid glomitis in heroin addiction.

The aim of the present work was to investigate the occurrence and immunological characteristics of chronic carotid glomitis in opiate addicts. Carotid bodies were sampled at autopsy from 50 subjects who died of heroin intoxication (mean age 28 years), and from 16 young (24 years) and 10 older subjects (66 years) who died of trauma. Sections were stained with haematoxylin-eosin and azan-Mallory, and immunohistochemistry was carried out with anti-CD45, -CD3, -CD8, -CD4, -CD20, -CD68, -CD56. Inflammatory aggregates were not observed in young cases, but were found in 21/50 (42%) opiate cases and in 4/10 (40%) older cases. Infiltrates were mainly located in subcapsular and interlobular positions, and were also found around nerve fibres. Inflammatory aggregates were mainly composed of T suppressor/cytotoxic lymphocytes (50-80%). Monocytic/macrophagic cells and B lymphocytes comprised about 10% and 5-20% of inflammatory cells, respectively. T helper lymphocytes were fewer and only rare Natural Killer cells were found. Chronic carotid glomitis must be included among the autopsy findings of opiate addiction, and may be ascribed to inflammatory reactions to exogenous immunogens or to responses to drug-induced degenerative changes of carotid body components.

Surgical anatomy of the radial nerve at the elbow.

An anatomical study of the brachial portion of the radial nerve with surgical implications is proposed. Thirty specimens of arm from 20 fresh cadavers (11 male, 9 female) were used to examine the topographical relations of the radial nerve with reference to the following anatomical landmarks: acromion angle, medial and lateral epicondyles, point of division between the lateral and long heads of the triceps brachii, lateral intermuscular septum, site of division of the radial nerve into its superficial and posterior interosseous branches and entry and exit point of the posterior interosseous branch into the supinator muscle. The mean distances between the acromion angle and the medial and lateral levels of crossing the posterior aspect of the humerus were 109 (+/-11) and 157 (+/-11) mm, respectively. The mean length and calibre of the nerve in the groove were 59 (+/-4) and 6 (+/-1) mm, respectively. The division of the lateral and long heads of the triceps was found at a mean distance of 126 (+/-13) mm from the acromion angle. The mean distances between the lateral point of crossing the posterior aspect of the humerus and the medial and lateral epicondyles were 125 (+/-13) and 121 (+/-13) mm, respectively. The mean distance between the lateral point of crossing the posterior aspect of the humerus and the entry point in the lateral intermuscular septum (LIS) was 29 (+/-6) mm. The mean distances between the entry point of the nerve in the LIS and the medial and lateral epicondyles were 133 (+/-14) and 110 (+/-23) mm, respectively. Our study provides reliable and objective data of surgical anatomy of the radial nerve which should be always kept in mind by surgeons approaching to the surgery of the arm, in order to avoid iatrogenic injuries.

Neurotensin receptor 1 immunoreactivity in the peripheral ganglia and carotid body.

In the present study we investigated, through immunohistochemistry, the presence and location of neurotensin receptor 1 (NTR1) in the peripheral ganglia and carotid body of 16 humans and 5 rats. In both humans and rats, NTR1 immunostained ganglion cells were found in superior cervical ganglia (57.4±11.6% and 72.4±11.4%, respectively, p<0.05), enteric ganglia (51.9±10.4% and 64.6±6.1%, p<0.05), sensory ganglia (69.2±10.7% and 73.0±13.1%, p>0.05) and parasympathetic ganglia (52.1±14.1% and 59.4±14.0%, p>0.05), supporting a modulatory role for NT in these ganglia. Positivity was also detected in 45.6±9.2% and 50.8±6.8% of human and rat type I glomic cells, respectively, whereas type II cells were negative. Our findings suggest that NT produced by type I cells acts in an autocrine or paracrine way on the same cell type, playing a modulatory role on chemoception.

The gracilis muscle and its use in clinical reconstruction: an anatomical, embryological, and radiological study.

The gracilis muscle is used widely in reconstructive surgery, as a pedicled or as a free microsurgical flap, for soft tissue coverage or as a functioning muscle transfer. Many studies, based on cadaver dissections, have focused on the vascular anatomy of the gracilis muscle and provided different data about the number, origin, and caliber of its vascular pedicles. Computed tomographic (CT) angiography of both thighs of 40 patients (35 males and 5 females, mean age: 63 years) have been analyzed to provide a detailed anatomical description of the arterial supply of the gracilis muscle. The gracilis muscle had a mean length of 41 +/- 2.1 cm. The principal pedicle enters the gracilis muscle at a mean distance (+/-SD) of 10 +/- 1 cm from the ischiopubic attachment of the muscle. Its caliber shows a mean value of 2.5 +/- 0.5 mm, and it is statistically larger when originating directly from the deep femoral artery (45%) than from its muscular branch supplying the adductors, i.e., the "artery to the adductors" (46%) (P < 0.01). A significant correlation between the caliber of the artery of the main pedicle and the volume of the gracilis muscle was found (P < 0.01). The mean number of distal accessory pedicles is 1.8 (range, 1-4,) and the artery of the first of these pedicles shows a mean caliber of 2.0 mm. There is no correlation between either the number or the caliber of the artery of the accessory pedicles and the volume of the gracilis muscle. CT angiography, providing detailed images of the muscular and vascular structures of the thigh of each patient, could be a useful preoperative study for the reconstructive surgeon. It would allow a personalized planning of a gracilis flap, reducing the risk of iatrogenic damage.

Anatomic distribution of apoptosis in medulla oblongata of infants and adults.

The aim of the study was to evaluate the distribution of apoptosis in the medullary nuclei of infants and adults who died of hypoxic-ischaemic injury. Apoptosis was studied by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labelling (TUNEL) in brainstems from 22 adults (7 subjects who died of opiate intoxication, 15 who died of other hypoxic-ischaemic injury) and 10 infants. The nuclei examined included the hypoglossal, dorsal motor nucleus of the vagus, nucleus tractus solitarii, nucleus of the spinal trigeminal tract, cuneate, vestibular and inferior olivary nuclei. A morphometric analysis with the optical disector method was performed to calculate the mean percentages (+/- standard deviation) of TUNEL-positive neuronal and glial cells for the sample populations. Opiate deaths did not have higher apoptotic indices than other adult hypoxic-ischaemic deaths. Statistically significant differences between adults and infants were found in the neuronal apoptotic indices of the cuneate (28.2 +/- 16.3% vs. 6.9 +/- 8.7%), vestibular (24.7 +/- 15.0% vs. 11.3 +/- 11.4%), nucleus tractus solitarii (11.2 +/- 11.2% vs. 2.3 +/- 2.4%), dorsal motor nucleus of the vagus (6.8 +/- 8.5% vs. 0.1 +/- 0.2%) and hypoglossal (6.6 +/- 5.7% vs. 0.1 +/- 0.2%), indicating higher resistance of the neuronal populations of these infant medullary nuclei to terminal hypoxic-ischaemic injury or post-mortem changes. Differences in neuronal apoptotic index were also statistically significant among nuclei, suggesting differential characteristics of survival. Nuclei with higher neuronal apoptotic indices were the cuneate, vestibular and nucleus of the spinal trigeminal tract, which are located in the lateral medullary tegmentum and share the same vascular supply from the posterior inferior cerebellar artery.

Expression pattern of squamous cell carcinoma antigen in oesophageal dysplasia and squamous cell carcinoma.

The aim of the present study was to evaluate the tissue expression of squamous cell carcinoma antigen (SCCA) in oesophageal dysplasia and squamous cell carcinoma (SCC) with reference to its clinico-pathologic and prognostic significance. Immunohistochemistry using SCCA polyclonal antibody was performed on SCCs from 61 surgical oesophagectomies. Fifteen cases of low-grade dysplasia (LGD) and 37 non-coexistent high-grade dysplasia (HGD) were also sampled from these materials, together with sixteen chronic cases of oesophagitis. SCCA immunoreactivity was present in the maturative compartments of all normal epithelia and oesophagitis. LGDs showed no SCCA immunoreactivity in the dysplastic proliferative component but only in the superficial normal layers. In 94.6% of HGDs, no SCCA immunoreactivity was detected throughout the thickness of the epithelium. In SCCs, SCCA expression higher than 25% was found in 54% of cases. SCCA positivity showed an inverse correlation with histological grade, whereas no statistically significant correlation was found with TNM classifications, stage, or survival. SCCA is not expressed in early oesophageal carcinogenesis but, in SCC, it represents an indicator of histologic differentiation. In differentiated SCC, SCCA may represent a negative factor for cancer invasiveness, through inhibition of proteases.

Endoscopic treatment of pseudosarcomatous squamous carcinoma of the esophagus: case report and personal experience.

Spindle cell (or pseudosarcomatous) squamous carcinoma (PSC) is a rare malignant neoplasm of the esophagus, potentially capable of causing lymph node and distant metastases. Indications for surgery are the same as for squamous cell carcinoma (SCC) of the esophagus. The aims of this paper were to report a case of endoscopically treated PSC and to review our experience of surgically-treated patients with PSC in order to identify patients potentially suitable for endoscopic treatment. In our series of 4,460 patients with carcinoma of the esophagus observed between 1980 and 2003, 28 (0.6%) had the histological features of PSC. One had a PSC histologically confirmed (8cm-long polyp with a 3cm-large base) and endoscopically treated for high surgical risk. The patient had a close follow-up with endoscopic biopsies and ultrasonography with no local recurrence at 3 years. The overall survival rate was 22% for PSC and 17% for SCC (P = n.s.); after 5 years, the survival rates were 22% and 13%, respectively (P = n.s.). In our opinion the limited tendency to parietal infiltration and the good chance of disclosure in an early stage with endoscopic ultrasonography, justify non-surgical solutions in patients with a high surgical risk, possibly associated with adjuvant chemo- and radiotherapy since lymph node involvement is reported in 50% of cases. The limited number of patients with PSC involved in the present series prevent any significant statistical comparisons between the different groups, but the survival rates were roughly the same in the nonsurgical curative therapy as in the curative resection group, while the chances of survival were significantly lower in patients given palliative surgery and or non-curative treatments (P < 0.05).

Persistence of embryonic pattern of hepatocaval venous junction and patent ductus venosus in Budd-Chiari syndrome.

We report an autopsy study on a case of Budd-Chiari syndrome (BCS) in a 44-year-old woman. Dissection showed that the outlets of the right hepatic vein (HV) and of the common trunk of the middle and left HVs appeared as two small depressed areas with narrow ostia. Histological examination showed recent thrombosis of the tributaries of the HVs and centrilobular congestion with necrosis of the hepatic parenchyma. The juxtacaval portions of the major HVs showed a cuneiform shape, because of marked dilation, with thread-like ostia, and multiple small outlets of minor hepatic veins were also present. The coexistence of patent ductus venosus may have prevented the development of the hepatocaval venous junction, with persistence of the embryonic pattern, composed of multiple small channels draining into the right hepatocardiac channel. The unusual hepatocaval venous junction may have predisposed to thrombosis of the HVs, causing BCS.

Sertoli cell tumor: a rare case in an elderly patient.

Sertoli-Leydig cell tumors constitute < 1% of ovarian tumors, mostly in young women with virilization; however, not all present endocrine manifestations. A 72-year-old female presented with an abdominal mass and no signs of virilization. Total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy and selective pelvic lymphadenectomy was performed. The pathologic diagnosis was poorly-differentiated sex cord-stromal tumor with Sertoli cells. No adjuvant chemotherapy or radiation was administered. At 12-month follow-up the patient showed no evidence of disease.

Selective stroke of the solitary tract nuclei in two cases of central sleep apnoea.

Central sleep apnoea (CSA) is a breathing disorder characterized by repetitive central apnoeas with hypoxia interrupted by hyperventilation phases. In the literature, there are reports of CSA caused by brainstem infarcts. We report two patients (38 and 53 years old) with longstanding history of central sleep apnoea who died during sleep. In both cases the autopsy revealed acute bilateral hypoxic lesions at the level of the solitary tract nuclei. In one case, symmetrical selective neuronal necrosis was found in the dorsal part of the solitary tract nuclei. A chronic obstructive vasculopathy was also found, with thickening and fibrosis of the smallest vessels of the medullary tegmentum. In the other case, bilateral infarctions were found with the base at the ependymal lining of the 4th ventricle floor and the apex towards the solitary tract. An acute intramural hemorrhagic lesion in the premedullary segment of the left vertebral artery was also found. Episodes of hypoxemic hypoxia during sleep may worsen the effects of focal oligohemic hypoxia in the medullary tegmentum. Selective stroke of the solitary tract nuclei may be the acute fatal lesion in patients with both central sleep apnoea and lesions of the vertebro-basilar system. To the best of our knowledge, this is the first neuropathologic report of acute medullary ischemic-hypoxic lesions which may not be considered the cause of the CSA because of their recent onset. Our findings suggest that CSA, besides being caused by ischemic events at the level of the medulla, may also contribute to pathogenesis of strokes, through hypoxia or hemodynamic oscillations.

Histopathology of carotid body in heroin addiction. Possible chemosensitive impairment.

AIMS: To perform a morphometric analysis of carotid bodies in opiate addicts. METHODS AND RESULTS: Carotid bodies were sampled at autopsy from 35 subjects who died of heroin intoxication (mean age 26 years), and from eight young (22 years) and eight older subjects (66.5 years) who died of trauma. Sections were stained with haematoxylin-eosin, azan-Mallory, and double-labelling immunohistochemistry with antineuronal specific enolase and anti-S100, to count type I and type II cells. Interlobular and intralobular connective tissue was increased both in the opiate cases (43.45 +/- 6.79%, P < 0.001, and 13.34 +/- 5.72%, P < 0.001, respectively) and older cases (46.67 +/- 1.65%, P < 0.001, and 9.62 +/- 2.11%, P < 0.05, respectively) compared with young cases (33.17 +/- 6.41% and 4.33 +/- 1.84%, respectively). The percentage of type II cells in the opiate cases (51.6 +/- 7.3%, P < 0.001) and in the older controls (49.0 +/- 7.2%, P < 0.01) was higher than in the young cases (37.9 +/- 3.0%). Among type I cells, the light cell percentage in the opiate cases (65.85 +/- 11%, P < 0.001) was reduced with respect to the two control groups (82.8 +/- 5.34%, young; 81.62 +/- 8.58%, older). CONCLUSIONS: The increases in connective tissue and type II cells are similar to findings in ageing and chronic pulmonary disease, and may be ascribed to glomic hypoxia. A direct action of opiates should be taken into account for the decrease in light cells in heroin addiction. The histopathological changes in the carotid body, by impairing chemosensivity, may play a role in the fatal cardiorespiratory derangement of heroin addicts.

Morphogenesis of the posterior inferior cerebellar artery with three-dimensional reconstruction of the late embryonic vertebrobasilar system.

The posterior inferior cerebellar artery (PICA) shows the most variable course among the cerebellar arteries, mainly at the level of the lateral medullary segment. Based on the correlation between the level of origin and the characteristics of the lateromedullary segment, we have proposed three patterns of course of the PICA. With the aim of understanding their embryological basis we review the interrelations between the developing cerebellum and the primitive hindbrain arterial plexus through the analysis of transverse serial sections of human embryos of 22.5 and 23 mm crown-rump length. Three-dimensional reconstruction of the vertebrobasilar system has been performed to study the morphology of the vascular networks. The cerebellar primordium is vascularized by the metencephalic plexus that will form the basilar artery and the superior cerebellar arteries. Due to the development of the pontine flexure the rhomboid lips approach and the cerebellum comes into contact with the myelencephalon; thus the myelencephalic plexus represents an acquired source of vascularization for the cerebellum with respect to the metencephalic plexus. The examination of the transverse sections shows that the vertebral and basilar arteries, superior cerebellar arteries, anterior inferior cerebellar arteries, and primitive lateral vertebrobasilar anastomoses are well recognizable. The three-dimensional reconstruction of the vessels shows that the PICA is not yet defined due to the persistence of a plexus of many thin vessels at the level of the lateral aspect of the myelencephalon, indicating that its origin and course are established at the end of the embryonic period. Based on the evolution of the primitive hindbrain plexus, we suggest that in synchrony with the progressive descent of the cerebellum the branches of the myelencephalic plexus succeed with a rostrocaudal progression in feeding the cerebellum and the morphogenesis of the PICA results from the selection of portions of this plexus. The high origin of the PICA from the basilar artery could be ascribed to its development from a rostral collateral of the plexus due to an early development of the vessel at the beginning of its embryonic lifetime. Moreover, the three patterns of course of the PICA could reflect the variable retention of the primitive lateral vertebrobasilar anastomosis in the trunk of the definitive PICA, which may be related to its level of origin.

Intraepithelial G3 adenocarcinoma of the endometrium after tamoxifen treatment.

CASE REPORT: In this paper we describe a case of endometrial carcinoma observed in a post-menopausal patient who was treated with tamoxifen for 5 years after a mastectomy for cancer. She came to our department because of vaginal bleeding 2 years after the end of tamoxifen treatment. TREATMENT: She underwent hysteroscopy and a D and C. A polypoid endometrium completely filled the uterine cavity and was carefully removed by curettage; histology showed a highly undifferentiated neoplasia with a component of serous adenocarcinoma, which was likely to originate from endometrial polyps. OUTCOME: The patient underwent radical hysterectomy, but no residual tumor was found in the uterus or in the tubes, ovary, or pelvic nodes, in spite of its low differentiation grade and high potential aggressiveness, and even though the patient was already symptomatic. Two years after surgery the patient is disease free, which is consistent with the evaluation of the surgical specimen, but unusual in poorly differentiated neoplasms.
