Neurofibromas developing in neurofibromatosis type 1 rarely grow to a large size. However, in cases of massive lesions, selection of optimal treatment tactics can be complicated.

To describe a successful experience of surgical treatment in a patient with giant neurofibroma type 1 affecting a massive pool of soft tissues.Clinical case. Patient, 22 years, sought medical help at the N.N. Blokhin National Medical Research Center of Oncology with diagnosis of neurofibromatosis type 1 with massive lesions in the tissues of the lower third of the back, gluteal region, thighs. The disease has existed since birth, family medical history is fraught: father died of malignant manifestation of a neurogenic tumor. The younger sister is also diagnosed with neurofibromatosis affecting the brain and manifesting through cafe au lait spots on the body. Due to massive tumors significantly decreasing the patient’s quality  of life, cytoreductive surgical treatment was prescribed aimed at maximally radical resection of all available tumors to alleviate the patient’s condition.Conclusion.

The effectiveness of efficient surgical interventions in patients with benign, borderline, and malignant bone tumors remains an important topic because such operations imply lower injury rate and volume of surgical intervention while being more physiological. In terms of radicality and consequently recurrence rates they are comparable to more traumatic surgeries such as segmental resections with various types of reconstructions (arthrodesis, endoprosthesis, auto- and allotransplantation using bone fragments, et al) and amputation.Aim. To analyze the results of intraosseous resection for benign, malignant, giant cell, and metastatic bone tumors.Materials and methods. Between 2015 and 2023, 45 interventions of intraosseous resection were performed in 44 patients: 19 (43 %) had enchondroma, 6 (14 %) – giant cell tumor, 4 (9 %) – fibrous dysplasia, 3 (7 %) – solitary bone cyst, 3 (7 %) – aneurysmal bone cyst, 2 (5 %) – chondromyxoid fibroma, 4 (9 %) – metastatic bone lesions, 1 (2 %) – osteoid osteoma, 1 (2 %) – benign fibrous histiocytoma, 1 (2 %) – chondrosarcoma G1 . Among them, 27 interventions were performed in combination with adjuvants (liquid nitrogen cryoablation, argon plasma coagulation, hydrogen peroxide, ethanol). In 24 patients, reconstruction was performed using lyophilized corpse bones, in 5 using autotransplant (fragments of the iliac crest), in 10 using plastic material (in 6 – polymethacrylate, in 4 – osseointegrative material “Rekost”), in 6 using xenoplastic material “Silorif.” Additionally, 16 surgeries were augmented with osteosynthesis (14 extramedullary and 3 intramedullary osteosyntheses).Results. Complications in the early postoperative period were observed in 3 (7 %) patients, in the late postoperative period in 2 (5 %) patients. At follow ups (between 2 and 97 months), 42 (95 %) patients did not have signs of recurrence. Musculoskeletal Tumor Society Score (MSTS) at these follow ups in recurrence-free patients was excellent (mean score – 93.6 %) and good (mean score – 77 %). Eastern Cooperative Oncology Group (ECOG) performance status also showed high functional potential of intraosseous resection: its mean value was 0.3.Conclusion. Use of intraosseous resection including augmentation with adjuvant measures, allowed to achieve excellent functional results in 42 (95 %) of patients with mean follow-up duration of 39.8 months. Fractures in 2 patients demonstrate the necessity of extramedullary osteosynthesis in surgeries on long bones experiencing high load irrespective of the volume of intervention. The obtained results show applicability and high effectiveness of intraosseous resection. For certain indications, it can be the treatment of choice.","PeriodicalId":504764,"journal":{"name":"Bone and soft tissue sarcomas, tumors of the skin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140729571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanism of such dimorphism is studied at various levels, mainly in the field of influence on the pathogenesis of sex hormones and their receptors, the effect of which is significantly related to the histogenesis of the tumor, its localization, the mechanism of malignant transformation and the stage of progression. Sex hormone receptors are often found in the early stages of tumor development and are lost during progression. At the same time, the expression of the same receptors in tumors of different histogenesis sometimes correlates with the opposite prognosis of the disease and sensitivity to hormonal therapy. For example, in uterine leiomyosarcomas, the expression of estrogen and androgen receptors correlates with a better prognosis and greater effectiveness of therapy, and in osteo- and fibrosarcomas, vice versa. Estrogens stimulate proliferation of osteosarcoma cells, and androgens that of rhabdomyosarcoma and small round cell tumor, which growth is inhibited by antiandrogens used in the treatment of prostate cancer. In this regard, when trying to include a hormonal component in a therapeutic complex, an individual study of the hormonal sensitivity of the tumor is necessary. One of the methodological approaches to this could be testing a culture of tumor cells from surgical material for sensitivity to agonists/antagonists of hormonal receptors separately and in combination with chemotherapy drugs.","PeriodicalId":504764,"journal":{"name":"Bone and soft tissue sarcomas, tumors of the skin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140730389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Merkel’s carcinoma is a neuroendocrine malignant epithelial skin tumor, rapidly progressive, prone to local recurrence and metastasis to regional lymph nodes and internal organs. The etiology and pathogenesis of Merkel’s carcinoma are still an insufficiently studied issue. Because of its rare occurrence, only single observations of Merkel’s carcinoma metastasis without an identified primary focus, most often with regional lymph node involvement, have been described in the world literature.Clinical case. This article presents a clinical case of metastatic lesion of inguinal lymph nodes with microinvasion into femoral artery in Merkel’s carcinoma without identified primary focus. After a comprehensive examination and onco-consilium the patient underwent surgical treatment in the scope of cytoreductive excision of the inguinal lymph node conglomerate on the right side and artery prosthesis with an autovenous graft. According to the routine postoperative pathomorphologic and immunohistochemical studies, the diagnosis of Merkel’s carcinoma metastasis was finally confirmed.Conclusion. Identification and description of such clinical cases are practically significant and can serve for formation of certain algorithms for treatment of Merkel’s carcinoma both with local manifestations and in progressive forms. Patients with Merkel’s carcinoma should be discussed in oncological consiliums, as treatment may include surgical stage, including biopsy of sentinel lymph nodes, adjuvant radiotherapy, chemotherapy and immunotherapy in case of tumor dissemination.","PeriodicalId":504764,"journal":{"name":"Bone and soft tissue sarcomas, tumors of the skin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140728014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
