The use of near-infrared imaging with indocyanine green in the ovarian tissue transplantation: a case report

The request for fertility preservation has consistently increased in recent years. To our knowledge this case report is the first to describe the application of near-infrared intraoperative imaging using indocyanine green (NIR-ICG) during ovarian tissue transplantation (OTT), to assist surgeon choosing the site of implantation of ovarian fragments. OTT was performed in a 42-year-old woman using NIR-ICG to evaluate the vascularisation of peritoneal area as the site of implantation for the ovarian graft. we believe this new approach could be useful in identifying the best reimplantation site.

Mogamulizumab and bexarotene are a promising association for the treatment of advanced cutaneous T-cell lymphomas: a case series

BACKGROUND

Treatment choices for patients with advanced-stage mycosis fungoides (MF) or Sézary syndrome (SS) who have failed first-line systemic therapies can be challenging, as several options are available. However, most evidence is based on observational and early phase studies due to the rarity of the disease. Mogamulizumab has recently been approved for the treatment of adult patients with MF or SS who have received at least one prior systemic therapy; it has a good tolerability profile prompting its use in combination with other agents. This article aims at describing the role of the concomitant use of bexarotene with mogamulizumab in this setting.

CASES PRESENTATION

To add information in the field, we describe our experience with four patients with MF/SS who failed first- and second-line treatments and started the combination mogamulizumab in addition to bexarotene. The combination of bexarotene with mogamulizumab in patients with advanced MF/SS after the failure of bexarotene alone obtained a response in all the four patients observed. The response was maintained longer than expected.

CONCLUSIONS

The combination is promising and deserves further study.

P-746 Clinical, laboratory and ultrasonographic risk factors for uterine artery arteriosclerosis: insights for uterus transplantation

Study question

What is the uterine artery arteriosclerosis prevalence in women undergoing total hysterectomy for benign diseases?

Summary answer

Uterine artery arteriosclerosis shows a prevalence of 70% in women undergoing total hysterectomy for benign diseases.

What is known already

Arteriosclerosis is defined as a chronic inflammatory disease involving arteries triggered by endothelial dysfunction. The presence of uterine artery arteriosclerosis might identify uteri to be excluded for uterus transplantation. Just one article assessed frequency of UAA in women scheduled for hysterectomy. The Authors observed UAA lesions, from intimal thickness to complex plaque, in all patients; but these data have not been validated in other study populations.

Study design, size, duration

This is a single center, observational, prospective, cohort study, carried out in a tertiary academic center from December 2020 to May 2021. Forty-two consecutive symptomatic patients refuse/ contraindications/intolerance to medical therapy and scheduled for total hysterectomy were enrolled in the study. Exclusion criteria were virgo patients and patients with specimen removal requiring morcellation. Women underwent preoperative assessment of medical history, gynecological examination, transvaginal ultrasound scan and serum tests.

Participants/materials, setting, methods

Two-cm length segments of ascending branch of uterine arteries specimens were harvested at a level of the internal cervical os, then divided, fixed in formalin and then embedded in paraffin. Serial sections were obtained with a thickness of 4 micron. Clinical data and serum tests were collected during preoperative evaluation for each patient. Transvaginal ultrasound was performed. We evaluated PI, RI and PSV as markers of vascular stenosis.

Main results and the role of chance

Forty women were included in the analyses. UAA prevalence was 70%. Among clinical and laboratory factors, means ± SD of body mass index (p = 0.04), total cholesterol (p = 0.03), and triglycerides (p = 0.049) were significantly higher in patients with UAA compared to patients without UAA. On the contrary, HDL mean ± SD (p = 0.02) was significantly lower in patients with UAA than those without UAA. Regarding ultrasonographic factors, uterine arteries with UAA showed higher PSV values compared to vessels without UAA (p = 0.04).

Limitations, reasons for caution

A potential limitation of the present study is the small sample size and the enrollment of women affected by uterine diseases requiring surgery. However, we considered unethical to provide histological data in a cohort of patients with regular uterus, thus not requiring hysterectomy.

Wider implications of the findings

To our knowledge, our study may be the first to evaluate the correlation between both clinical, laboratory and ultrasonographic factors and the presence of UAA. Our findings might direct future studies aiming to improve UTx outcomes.

Sclerosing nevus with pseudomelanomatous features: dermoscopic and confocal aspects

BACKGROUND

Sclerosing nevus with pseudomelanomatous features (SNPFs) is a clinical and pathologic entity that mimics melanoma both clinically and histologically. The lesion is a melanocytic nevus, histologically characterized by fibrosis and a pseudomelanomatous proliferation. It is typically seen in young to middle-aged individuals, mainly on the back, where microtrauma or inflammatory changes are more frequent. Dermoscopic description of SNPF has been reported so far in one case series.

OBJECTIVE

The aim of our study was to describe the dermoscopic and confocal features of SNPF.

METHODS

Histopathologically confirmed cases of SNPF were retrospectively collected from three referral centres in Italy. Only lesions with available clinical, dermoscopic and histopathological data were included; confocal images were also retrieved, when available. Lesions were evaluated for the presence of 12 dermoscopic and five confocal criteria previously described.

RESULTS

The study population included 93 lesions in as many patients (71 men and 22 women; median age: 38 years). Dermoscopically, we found a predominance of dark colours, in particular brown and blue, which were found in all lesions and the vast majority of the lesions (86/93; 92.5%) displayed at least one structureless area. By the combination of colours and structures, we observed that the majority of the lesions (67/92; 72%) were characterized by more than one structure and more than one colour. Confocal evaluation was performed on a subset of 24/93 lesions showing a regular architecture pattern (19/24 cases, 79%), with a predominance of the ringed pattern. The presence of focal cytologic atypia at the dermal-epidermal junction was present in 12/24 cases (50%) with a prevalent dendritic-shaped cell proliferation.

CONCLUSIONS

The current study demonstrated that SNPF was frequently characterized, on dermoscopic examination, by more than one structure and more than one colour and on confocal microscopy by a regular ringed pattern with focal dendritic atypical cells.

Reflectance confocal microscopy analysis of equivocal melanocytic lesions with severe regression

BACKGROUND

The differential diagnosis between regressing nevi and melanoma might be challenging; regressing areas can represent a confounding factor for the diagnosis and the histology still remain mandatory to rule out melanoma. Reflectance confocal microscopy may add valuable information by revealing features suggestive of the nature of the melanocytic proliferation.

OBJECTIVE

To assess the impact of confocal microscopy in the management of regressive melanocytic lesions.

METHODS

The dermoscopic analysis of 92 melanocytic lesions showing that more than 30% of regressions have been retrospectively considered, among them, 32 melanocytic lesions with a 7 check point list ≥3 they were assessed at the rcm and subsequently excised. For each selected lesion, dermoscopic features of regression (white scar-like areas, blue areas, blue white areas), distribution of regressing areas (central, peripheral, or both) and the percentage of regression have been examined by an expert in dermoscopy, blinded to the histological and confocal diagnosis. Subsequently, two experts in confocal microscopy revaluated, blinded from histology, RCM images.

RESULTS

Of the 32 lesions analyzed, 23 (71.5%) were diagnosed histologically as nevi, and 9 (28.5%) as melanomas. 26 of 32 lesions (81.5%) exhibited regression >50% of the overall. On RCM, 11 lesions have been interpreted as malignant and 21 as benign. On RCM the majority of nevi exhibited regular architecture without cytological atypia. Epidermal disarray, pagetoid infiltration, disarranged dermo-epidermal junction architecture and atypical nests were considered as suspicious for malignancy. Good concordance between confocal readers has been detected.

CONCLUSION

A combined dermoscopic/confocal approach can be used for the management of lesions exhibiting dermoscopic features of regression in order to provide a more conclusive pre-histological diagnosis avoiding a high number of unnecessary excisions. Limits of this study were represented by the relatively small number of lesions and the retrospective approach. Further, prospective studies on a larger number of cases, will be necessary in order to compare the efficacy of dermoscopy alone versus dermoscopy in combination with RCM for the evaluation of regression, suspected pigmented lesions.

[Malignant tumours arising in extraovarian endometriosis: three case reports and review of the literature]

In its extraovarian form, co-existence of carcinoma and endometriosis is a sufficient argument used in favour of the malignant transformation of endometric lesions. Estrogen as well as the loss of 5q chromosome heterozygosity are considerate as initiators of that type of carcinogenesis. Endometrioid histological type is the most frequent and is revealed usually by abdominal pain. The incidence of carcinoma arising in endometriosis is about 0.8% and 5-year survival rate of pelvic endometrioid form is about a 100% after surgery and radiotherapy.

[Conservative surgery in breast cancer: combination skin incision for a better cosmetic result]

The authors report a surgical procedure for lumpectomy combining both areolar and radial skin incision for cancer localized in the inferior, or at the junction of the superior and inferior part of the breast. The skin incision have an "amphore-like" appearance. It allows an easy mammoplasty with all cancerologic securities.

Les métastases intrathyroïdiennes du cancer du rein à cellules claires : présentation de sept cas et revue de la littérature

PURPOSE

The aim of this study was to retrospectively report clinical manifestations, type of treatment, survival rate of thyroid metastases from renal carcinoma.

PATIENTS AND METHODS

Seven patients were retrospectively collected from files of different Burgundy's hospitals. All renal and thyroid gland specimens were controlled by the anatomopathologist.

RESULTS

Tumors occurred in four women and three men (mean age: 66 years). Symptoms were generally a solitary mass. The metastatic tumor to the thyroid gland was the initial presentation of renal carcinoma in one case. In the other cases, patients had documented previous evidence of renal carcinoma as remotely 8.1 years before the thyroid metastases. Thyroglobulin immunohistochemistry was always negative in the foci of metastatic renal carcinoma. All patients had surgical resection of there metastasis. The majority of patients died with disseminated malignancies (mean: 38.1 months after there thyroid resection). Three patients are still alive, one after a complementary pancreatic resection for a secondary pancreatic metastasis and one other with cervical and mediastinal lymph node recurrence.

CONCLUSIONS

Surgical treatment of the metastatic disease is suggested, as this may prolonged patient survival.
