RESUMO

Pelvic exenteration (PE) is a radical oncological surgical procedure proposed in patients with recurrent or persistent gynecological cancers. The radical alteration of pelvic anatomy and of pelvic floor integrity can cause major postoperative complications. Fortunately, PE can be combined with reconstructive procedures to decrease complications and functional and support problems of pelvic floor, reducing morbility and mortality and increasing quality of life. Many options for reconstructive surgery have been described, especially a wide spectrum of surgical flaps. Different selection criteria have been proposed to select patients for primary perineal defect flap closure without achieving any strict indication of the best option. The aim of this review is to focus on technical aspects and the advantages and disadvantages of each technique, providing an overview of those most frequently used for the treatment of pelvic floor defects after PE. Flaps based on the deep inferior epigastric artery, especially vertical rectus abdominis musculocutaneous (VRAM) flaps, and gracilis flaps, based on the gracilis muscle, are the most common reconstructive techniques used for pelvic floor and vaginal reconstruction. In our opinion, reconstructive surgery may be considered in case of total PE or type II/III PE and in patients submitted to prior pelvic irradiation. VRAM could be used to close extended defects at the time of PE, while gracilis flaps can be used in case of VRAM complications. Fortunately, numerous choices for reconstructive surgery have been devised. As these techniques continue to evolve, it is advisable to adopt an integrated, multi-disciplinary approach within a tertiary medical center.

RESUMO

OBJECTIVE: Eccrine porocarcinoma (EPC) is a malignant adnexal tumor accounting for about 0.005% of skin tumors. The standard treatment of EPC is the complete surgical excision of the primary lesion and of the clinically involved lymph nodes. There is limited evidence regarding the role of radiotherapy (RT) in managing EPC after surgery. Therefore, the aim of this multidisciplinary systematic review is to analyze the available evidence about postoperative RT in the curative treatment of EPC. MATERIALS AND METHODS: A systematic search strategy was launched trough the main scientific databases including PubMed, Scopus and Cochrane. An additional manual search and a chain citation were performed about potentially relevant papers. The key words used for the search included "eccrine porocarcinoma", "porocarcinoma", "radiotherapy", "radiation therapy", "adjuvant radiotherapy" and "postoperative radiotherapy". RESULTS: A total of 104 publications were identified and 14 papers were included in the final analysis. The only articles found on adjuvant RT in EPC were case reports published between 1996 and 2019. There was a slight female prevalence (57% female/43% male) with a mean age of 65 years (range 37-85). Head-and-neck region was the most frequently involved anatomical site followed by legs. CONCLUSIONS: Adjuvant radiotherapy after surgical removal of EPC could be considered in cases with positive or close margins and in cases with unfavorable histological features. In view of limited literature data and the rarity of EPC the best treatment sequence should always be discussed within the frame of a multidisciplinary setting. ADVANCES IN KNOWLEDGE: adjuvant radiotherapy after surgical removal of EPC could be considered in cases with positive or close margins and in cases with unfavorable histological features.

RESUMO

Transient osteoporosis of the hip (TOH) is usually reported in middle-aged men or during pregnancy as a benign self-limiting condition. Nevertheless, its impact on quality of life in terms of pain and disability is considerable. Also, it can lead to insufficiency fractures or, more rarely, evolve into osteonecrosis. This condition is anecdotally described in the pediatric age and very little is known about how it may affect the growing bone. We herein describe a case of TOH in a 10-year-old child treated at our pediatric rheumatology service and summarize the pediatric cases of TOH previously reported in literature. There are two points of interest in our case report, the first one being the unusual complication of TOH with a femoral physis fracture and the second the complete recovery after the off-label therapy with bisphosphonates. We suggest that interventional medical treatment could be considered in selected cases of juvenile TOH, to prevent any possible irreversible damage on the femoral physis. As far as we know, this is the first report of neridronate employment in children affected by TOH.

RESUMO

OBJECTIVE: The aim of our systematic review was to assess the role of interventional radiotherapy (IRT, brachytherapy) in the management of primary and/or recurrent vulvar carcinoma. EVIDENCE ACQUISITION: A systematic research using PubMed, Scopus and Cochrane library was performed. ClinicalTrials.gov was searched for ongoing or recently completed trials, and PROSPERO was searched for ongoing or recently completed systematic reviews. Only full-text English-language articles related to IRT for treatment of primary or recurrent VC were identified and reviewed. Conference paper, survey, letter, editorial, book chapter and review were excluded. Time restriction (1990-2018) as concerns the years of the publication was considered. EVIDENCE SYNTHESIS: Primary disease: the median 5-year LC was 43.5% (range 19-68%); the median 5-year DFS was 44.5% (range 44-81%); the median 5-year OS was 50.5% (range 27-85%). Recurrent disease: the median 5-year DFS was 64% (range 56-72%) and the median 5-year OS was 45% (range 33%-57%). Acute ≥ grade 2 toxicity was reported in three patients (1.6%). The severe late toxicity rates (grade 3-4) ranged from 0% to 14.3% (median 7.7%). CONCLUSION: IRT as part of primary treatment for primary and/or recurrent vulvar cancer is associated with promising clinical outcomes.

RESUMO

OBJECTIVE: To evaluate the feasibility and clinical application of fusion imaging with virtual navigation, combining 18 F-fluorodeoxyglucose (18 F-FDG) positron emission tomography/computed tomography (PET/CT) with real-time ultrasound imaging, in assessing superficial lymph nodes in breast-cancer and gynecological-cancer patients. METHODS: This was a pilot study of breast- and gynecological-cancer patients with abnormal uptake of 18 F-FDG by axillary or groin lymph nodes on PET/CT scan, examined at our institution between January 2017 and May 2019. Fusion imaging was performed, uploading preacquired PET/CT DICOM images onto the ultrasound machine and synchronizing them with real-time ultrasound scanning performed at the lymph-node site. In the first phase, we assessed the feasibility and reliability of fusion imaging in a series of 10 patients with suspicious lymph nodes on both PET/CT and ultrasound, and with full correspondence between both techniques in terms of size, shape and morphology of the lymph nodes (Group A). In the second phase, we included 20 patients with non-corresponding findings between PET/CT and ultrasound: 10 patients with lymph nodes that were suspicious or pathological on PET/CT scan but not suspicious on ultrasound assessment (Group B), and 10 patients with suspicious or pathological lymph nodes on both PET/CT and ultrasound but with no correspondence between the two techniques in terms of number of affected lymph nodes (Group C). RESULTS: In the 30 selected patients, fusion imaging was assessed at 30 lymph-node sites (22 inguinal and eight axillary nodes). In the first phase (Group A), the fusion technique was shown to be feasible in all 10 lymph-node sites evaluated. In the second phase, fusion imaging was completed successfully in nine of 10 cases in Group B and in all 10 cases in Group C. In all groups, fusion imaging was able to identify the target lymph node, guiding the examiner to perform a core-needle aspiration biopsy or to inject radiotracer for selective surgical nodal excision, according to the radio-guided occult lesion localization technique. CONCLUSION: Fusion imaging with virtual navigation, combining PET/CT and real-time ultrasound imaging, is technically feasible and able to detect target lymph nodes even when PET/CT and ultrasound findings are inconsistent. Fusion imaging can also be used to guide the performance of core-needle aspiration biopsy, avoiding further surgical diagnostic procedures, or the injection of radiotracer for selective surgical nodal excision, enabling more sparing, selective surgery. This innovative technique could open up multiple diagnostic and therapeutic opportunities in breast and gynecological oncology. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMO

OBJECTIVE: To assess the accuracy of preoperative ultrasound examination for predicting lymph-node (LN) status in patients with vulvar cancer. METHODS: This was a single-institution retrospective observational study of all women with a histological diagnosis of vulvar cancer triaged to inguinal surgery within 30 days following ultrasound evaluation between December 2010 and January 2016. For each groin examined, 15 morphological and dimensional sonographic parameters associated with suspicion for LN involvement were examined. A morphometric ultrasound pattern (MUP) was expressed for each groin, classifying the inguinal LN status into five groups (normal; reactive-but-negative; minimally suspicious/probably negative; moderately suspicious; and highly suspicious/positive) according to subjective judgment, followed by stratification as positive or negative for metastasis according to morphometric binomial assessment (MBA). In cases of positive MBA, fine-needle aspiration cytology was performed. Combining the information obtained from MUP and cytologic results, a binomial final overall assessment (FOA) was assigned for each groin. The final histology was considered as the reference standard. Comparison was performed between patients with negative and those with positive LNs on histology, and receiver-operating-characteristics curves were generated for statistically significant variables on univariate analysis, to evaluate their diagnostic ability to predict negative LN status. RESULTS: Of 144 patients included in the analysis, 87 had negative inguinal LNs and 57 had positive LNs on histology. A total of 256 groins were analyzed, of which 171 were negative and 85 showed at least one metastatic LN on histology. The following parameters showed the greatest accuracy, with the best balance between specificity and sensitivity, in predicting negative LN status: cortical (C) thickness of the dominant LN (cut-off, 2.5 mm; sensitivity, 90.0%; specificity, 77.9%); short-axis (S) length of the dominant LN (cut-off, 8.4 mm; sensitivity, 63.9%; specificity, 90.6%); C/medulla (M) thickness ratio of the dominant LN (cut-off, 1.2 mm; sensitivity, 70.4%; specificity, 91.5%), the combination of S length and C/M thickness ratio (sensitivity, 88.9%; specificity, 82.4%); and the FOA analysis (sensitivity, 85.9%; specificity, 84.2%). CONCLUSIONS: Preoperative ultrasound assessment, with or without the addition of cytology, has a high accuracy in assessing inguinal LN status in patients with vulvar cancer. In particular, the combination of two ultrasound parameters (S length and C/M thickness ratio) provided the greatest accuracy in discriminating between negative and positive LNs.

RESUMO

OBJECTIVE: To evaluate the feasibility of fusion of ultrasound imaging and three-dimensional (3D) single-photon-emission computed tomography/computed tomography (SPECT/CT) in detecting sentinel lymph nodes in women with vulvar cancer. METHODS: This was a prospective pilot single-center study. Patients with vulvar cancer who were candidates for sentinel lymph-node biopsy were enrolled between December 2018 and February 2019. Fusion imaging virtual navigation using 3D SPECT/CT and ultrasound was performed to investigate the tumor-draining lymph node. All clinical, imaging, surgical and histological information was collected prospectively and entered into a dedicated Excel file. Feasibility and success of fusion imaging virtual navigation and time needed to perform the three steps of fusion imaging were evaluated. RESULTS: Ten lymph-node sites were evaluated in five consecutive women with a histological diagnosis of vulvar cancer. Fusion imaging virtual navigation was feasible and completed successfully for all (10/10) draining sites. Median overall time to perform fusion imaging was 32 (range, 25-40) min and the time decreased from the first to the last examination. CONCLUSIONS: The present study demonstrated that fusion imaging virtual navigation using 3D SPECT/CT and ultrasound is feasible and able to detect sentinel lymph nodes in women with vulvar carcinoma. Fusion imaging using ultrasound for detection of sentinel lymph nodes opens up multiple diagnostic and therapeutic opportunities in gynecological oncology. Copyright © 2019 ISUOG.

RESUMO

OBJECTIVE/PURPOSE: Extramammary Paget disease (EMPD) is a rare neoplasm of the skin generally affecting the anogenital area. Because of the low-frequency of the disease, no specific guidelines about the treatment strategy are available. Surgery is the recommended therapy for resectable and localized disease, but several other local treatments have been reported such as radiotherapy (RT). Most articles report small retrospective studies, referring to patients treated decades ago with large heterogeneity in terms of RT dose and technique. The aim of this study was to systematically review the main experiences in RT for the treatment of EMPD in the past 30 years. MATERIALS AND METHODS: A systematic search of the bibliographic databases PubMed and Scopus from January 1986 to January 2017 was performed including studies published in English, Italian, Spanish, French, and German language. RESULTS: According to the search strategy, 19 full-text articles, published from 1991 to 2015, fulfilled inclusion criteria and were included in the final review. All articles were retrospective analyses with no randomized controlled trials. These studies evaluated 195 EMPD patients treated with RT, delivered in several settings. A large variability in terms of RT doses, fractionation, clinical setting, and techniques was found.Radiotherapy was administered as definitive treatment for primary or recurrent disease after surgery in 18 studies with doses ranging from 30 to 80.2 Gy delivered in 3 to 43 fractions. Radiotherapy was administered as postoperative adjuvant treatment in 9 articles with doses ranging between 32 and 64.8 Gy in 20 to 30 fractions. Two studies reported the RT use in preoperative neoadjuvant setting with doses ranging between 40 and 43.30 Gy, and 2 experiences reported the RT treatment for in situ EMPD, using 39.6 to 40 Gy. Adverse events were reported in almost all but 2 articles and were grade 2 or lower.The 18 studies evaluating RT as definitive treatment for primary or recurrent disease after surgery reported a complete response rate ranging from 50% to 100%, with a variable rate of local relapse or persistent disease ranging from 0% to 80% of cases. The 9 studies evaluating RT as postoperative adjuvant treatment reported a local relapse or persistent disease rate of 0% to 62.5%. A dose-response relationship was reported suggesting doses greater than or equal to 60 Gy for gross tumor volume treatment. Local control, disease-free survival, and overall survival at 12, 20, and 60 months have been retrieved for available data, respectively.In patients with EMPD and concurrent underlying internal malignancy, the prognosis was often worsened by the latter. In this setting, literature analysis showed a potential RT palliative role for symptoms control or local control maintenance.Derma tumor invasion greater than 1 mm and lymph node metastases were reported to be important prognostic factors for distant metastases or death. CONCLUSIONS: To date, literature highlights the role of RT in the management of EMPD, but with low level of evidences.

RESUMO

OBJECTIVE: The study aims were: 1) to verify the role of sentinel node biopsy (SNB) in a subset of patients with clinical N0 (cN0) invasive vulvar cancer (VC) who were still candidates for radical inguinal surgery according to the current guidelines; 2) to investigate whether a preoperative 18F-FDG PET/CT (PET/CT) evaluation could improve the selection of node negative patients. METHODS: From July 2013 to July 2016, all patients with VC admitted to our Division were evaluated by standard imaging and clinical exam. Among the patients assessed as cN0 we enrolled those unsuitable for SNB, due to: T > 4 cm, multifocal tumors, complete tumor diagnostic excision, contralateral nodal involvement and local recurrence. A preoperative PET/CT was performed. For each patient surgery included SNB, performed using a combined technique (radiotracer plus blue dye), followed by standard inguino-femoral lymphadenectomy. The reference standard was histopathology. RESULTS: Forty-seven patients entered the study for a total of 73 groins. Histopathology revealed 12 metastatic SNs in 9 groins. No false negative SNs were found (NPV 100%). PET/CT showed a negative predictive value of 93%. CONCLUSIONS: Our data suggest that SNB is accurate and safe even in cN0 patients currently excluded from this procedure, providing that a careful preoperative selection is performed. PET/CT allows a reliable assessment of LN status and may be an effective support for the selection of patients who are safe candidates for SNB.

RESUMO

OBJECTIVE: A case of misdiagnosed acral melanoma of the hallux and its diagnostic challenge are herein presented. Acral melanoma is insidious and subtle. A methodic approach to any suspicious lesions is mandatory. A case of misdiagnosed acral melanoma of the hallux is herein reported in a 66-year-old healthy man. Suggestions concerning similar non-healing lesions are herein presented. MATERIALS AND METHODS: It was firstly clinically diagnosed and treated as a micosis at another centre. The absence of any amelioration after three years pushed us to perform a biopsy. RESULTS: An acral melanoma was revealed, treated by amputation. CONCLUSIONS: In case of a non-healing ulcer of the lower extremities, melanoma should be taken into consideration. Even in absence of any suggestive risk factors or clear signs of melanoma, the lack of any improvement after treatment should raise doubts about diagnosis. In particular, biopsy is advisable as a first attempt to guide the management.

RESUMO

BACKGROUND: Lipomas are the most common type of soft tissue benign tumor. They can be either isolated entities or involved in a multiple lipomatosis, which may have a familial basis or be an acquired condition. AIM: Chemotherapy and/or blood stem cell transplantation may be plausible causes of multiple lipomatosis. MATERIALS AND METHODS: A 28 year-old patient was diagnosed with non-seminomatous germ cell left testicular cancer. The patient was addressed to chemotherapy and peripheral blood stem cell chemomobilization. After stem cells collection, the patient underwent autologous peripheral blood stem cell transplant. RESULTS: A subsequent de novo multiple lipomatosis onset developed. CONCLUSIONS: Although this is a preliminary study and further elaborations are needed, dermatologists and surgeons facing with multiple lipomatosis should consider previous chemotherapy and peripheral blood stem cell mobilization/transplant as possible causes of its onset.

RESUMO

BACKGROUND: Literature data report an association between some vitamin D receptor (VDR) polymorphisms and different kinds of tumours, including malignant melanoma (MM). Only three VDR polymorphisms (FokI, TaqI and A-1012G) have been investigated in association with the presence of cutaneous MM or the development of metastases. OBJECTIVES: The present paper analyses for the first time the association between BsmI polymorphism and MM prevalence together with Breslow thickness. In addition, the FokI single nucleotide polymorphism was also determined. METHODS: One hundred and one patients with MM and 101 healthy donors matched for age and sex were enrolled. Molecular VDR typing was performed by means of restriction fragment length polymorphism analysis. RESULTS: All cases and controls were in Hardy-Weinberg equilibrium for BsmI, FokI and A-1012G. Significant associations were found between the BsmI bb genotype frequency and MM (P = 0.02) along with Breslow thickness (P = 0.001). This same behaviour was not observed for the FokI or A-1012G polymorphisms. Multivariate logistic regression analysis confirmed these significant results after correction for age, gender, skin type and MM localization. CONCLUSIONS: Although the biological meaning of the effects exerted by BsmI polymorphism is still under debate, the statistical association found in the present study suggests that further work should be done to verify this variant as a possible risk marker for MM and its aggressiveness, also considering that the real association may be due to other unknown genes linked to the BsmI b allele.

RESUMO

We report the case of a complete duplication of the glans, with prepuce and a blind end urethra just proximal to the dorsal aspect of the balanopreputial fold. The malformation was not evident at birth and during childhood, and became manifest only at puberty, with the growth of the external genitalia. It was not associated with other urinary malformations. Surgical excision was easy and uneventful.

RESUMO

Mucous cysts formation following a rhinoplasty is a rare complication. Only 16 cases have been reported. The cysts seem to arise from mucosal remnants left in the subcutaneous layer and must be distinguished from other complications causing postoperative swelling of the nose, such as foreign body, paraffinoma and bony or cartilagineous fragments. We describe two cases of dorsal mucous cysts following rhinoplasty, provide a review of the concerning literature and discuss the removal of the lesions by nasal endoscopy. Nasal endoscopy allows excellent exposure of the operative field, without the need of open rhinoplasty technique, allowing fast healing, minor swelling and no external scar.

RESUMO

Lateral osteotomy is a very important step in a cosmetic rhinoplasty; it allows the surgeon to narrow the nose, to close the open roof created after hump removal, and to achieve symmetry of an asymmetrical nasal bony framework. In most patients a single lateral osteotomy reaches the expected result, with excellent cosmetic outcome, good stability, and rapid healing. We find that double lateral osteotomy is useful in managing severe asymmetry of nasal walls in patients with too prominent and thick maxillary processes that join asymmetrically together with nasal bones. It is also valuable in correcting very large and wide noses. We review our experience of about 1660 rhinoplasties with more than one year follow-up. Two hundred and ten cases (12.65%) had been treated with monolateral, or bilateral double osteotomy. We evaluate postoperative aesthetic and functional results.

RESUMO

We report the case of a patient presenting with eyelid hernias who required bilateral upper and lower blepharoplasty; histological examination of the excised fat revealed B-cell non-Hodgkin's lymphoma. At diagnosis, the disease was already systemically advanced, but the patient was asymptomatic. No sign of disease had been detected in the preoperative tests. The bilateral orbital presentation of a systemic lymphoma is very rare, and is usually accompanied and revealed by exophthalmos, increased tear secretion, diplopia and decreased visual acuity. To our knowledge, this is the first case in which lid hernias were the first and only clinical sign of such a systemic disease.

RESUMO

Oncocytic tumours rarely affect the major salivary glands, accounting for less than 1% of all salivary-gland tumours. The World Health Organisation classification groups these tumours into three principal types: diffuse oncocytosis, focal adenomatous oncocytic hyperplasia and oncocytoma. Diffuse hyperplastic oncocytosis is the rarest lesion: only six cases have been previously reported in the literature. This condition of putative hyperplastic pathogenesis follows a benign course, whereas oncocytomas may recur after excision. No metastatic dissemination or recurrence of diffuse hyperplastic oncocytosis has been reported. We present and discuss a new case of diffuse hyperplastic oncocytosis of the parotid gland.

RESUMO

The authors examined the effect of twisting on the patency of microvascular anastomoses 3 days after surgery. A total of 69 male Wistar rats were divided randomly into four groups. The femoral arteries and veins were dissected for a standard distance. A total of 69 microarteriorrhaphies and 68 microvenorrhaphies were performed at 0 deg and with twist of the vessel ends of 90, 180, and 270 deg. Three-day patency rates for arterial microanastomoses were 100% with a 0-deg twist, 80.9% with a 90-deg twist, 68.4% with a 180-deg twist, and 64.2% with a 270-deg twist. Three-day patency rates for venous microanastomoses were 100% with a 0-deg twist, 85% with a 90-deg twist, 28.5% with a 180-deg twist, and 25% with a 270-deg twist (p = 0.047 for arteries, p = 0.001 for veins). These data are statistically significant. Moreover, assuming the risk of thrombosis to be 1 for microanastomosis without twisting, the odds ratio for the risk of vessel thrombosis for 270-deg twisting (the maximal examined degree of arterial and venous twist in the current study) is 10.08 for arterial anastomosis and 226.85 for venous anastomosis.
