Background. Esthesioneyroblastoma is a rare malignant tumor arising from olfactory neuroepithelium of the nasal cavity. It is an aggressive local tumor. It accounts for 3 to 6% of cases of nasal and sinus cancer. Occurs at any age. Due to the rarity of the disease, there are no uniform standards of treatment. A multimodal and interdisciplinary approach is recommended. Aim. To present the results of a retrospective study of patients with esthesioneuroblastoma. Materials and methods. The retrospective study was carried out using the database of departments of radionuclide diagnostics of Nuclear Medicine Centres from 2012 to 2022. Ten patients with histologically confirmed diagnosis of esthesioneyroblastoma were identified. Results. Age of patients from 29 to 67 years, median 51 years. Men and women equal. The clinical picture was dominated by a sense of nasal congestion and various nose impairments 8 and 7 patients. The tumor was more often confined to the left side of the nose. Computer tomography (CT), magnetic resonance imaging and positron emission tomography combined with CT (PET/CT) were used for diagnosis, estimation of tumor process prevalence and outpatient observation. Stage A by Kadish was identified in 2 cases, and stage B in 1 patient. Stage C 6 patients predominated. D was diagnosed in 1 patient. The use of PET/CT clarifies the primary stage, the effect of therapy, provides disease control during dynamic observation. The SUVmax median for primary tumor was 7.43 (4.319.1). A multi-modal approach is used to treat esthesioneuroblastoma. The surgical method is performed by 4 patients with subsequent radiation therapy. Radiation therapy was carried out at the first stage of 3 patients, the total focal dose was 66 Gy. Polychemotherapy followed by radiotherapy was used in 3 cases. Duration of observation ranged from 8 to 108 months, median 47.5 months. Conclusion. Esthesioneyroblastoma is a rare malignant nasal tumor. The peak of the disease falls on 5070 years. No gender differences have been identified. The main clinical symptoms are nasal congestion 8 patients and various smelling disorders 7 patients. PET/CT is the main imaging method in the diagnostic, evaluation and observation phases. In this case, most often (6 patients) is determined stage C by Kadish.
Introduction. Brain metastases can occur in almost all gynecological malignancies and, despite modern therapeutic options, have a poor prognosis. Brain metastases from vulvar cancer are considered to be rare. In the literature, the reports on these cases have identity character. The aim is to show clinical observation of the patient with vulvar cancer with brain metastases. Results. Patient S., 60 years old, with stage I р T1N0M0 vulvar cancer underwent vulvectomy in January 2018. During the histological study in the subepithelial layers were the areas of kraurosis with the growth of squamous cell keratinous carcinoma. Taking into account the prevalence of the tumor process, adjuvant treatment was not carried out. Two years later, in January 2020, there were focal symptoms in form of weakness in the left upper and lower limbs, an unsteady gait, a generalized weakness. During magnetic resonance imaging (MRI) of the brain in the occipital lobe paraventricular with intensive perifocal edema to the right was determined cystic-solid formation with rough edges which size was 293365 mm without clinically significant mass-effect. The middle structures were not displaced. Positron emission tomography-computed tomography (PET/CT) was performed to detect the prevalence of the tumor process. Data on the presence of the active specific process at the time of study were not received. Taking into account the absence of other indicators of generalization process, whole brain radiation therapy (single fraction dose of 3 Gy, total radiation dose of 30 Gy) was carried out, followed by the application of Temodal. The patient was examined in 6 months. There were no signs of progression. Conclusion. Brain metastases from vulvar cancer are considered to be rare. This clinical case is interesting because brain metastases have been the only manifestation of the progression of the tumor process in the absence of regional lymph nodes damage. The main diagnostic method is MRI of the brain. The use of PET/CT helps to detect the prevalence of the tumor process. The metastases have been detected after 36 months from the date of the initial diagnosis of the cancer. Radiation therapy is a method of choice of brain metastases treatment.
Introduction. Papillary thyroid cancer (PTC) usually metastasizes into the central and lateral lymph nodes (LNs) of the neck. Metastases into the retropharyngeal and parapharyngeal LNs are rare. Their presence attests to aggressive PTC.The study objective is to describe a rare case of metastases of papillary radioiodine-refractory PTC into the parapharyngeal LN.Clinical case. In 2015, female patient K., 40 years old, underwent thyroidectomy due to PTC. Histological examination verified papillary PTC with growth through the capsule and ingrowth into the surrounding tissues and muscles. In a separately admitted LN, metastases of the same cancer were observed. One year later, regional metastases in the lateral neck LNs were detected. Radioiodine therapy (activity 131I 4.5 GBq) was performed followed by fascial circular section of the neck tissues on the right per thyroid type. Morphological examination verified presence of papillary PTC metastases in 4 LNs. In January of 2018, positron emission tomography showed metastases in the paratracheal LNs. Central neck lymph node dissection was performed. Per histological conclusion, fat tissue and LN contained multiple metastases of papillary PTC. In October of the same year, repeat radioiodine therapy (activity 131I 3.0 GBq) was performed. Thyroglobulin levels increased. In June of 2020, repeat positron emission tomography showed a single metastasis in the parapharyngeal LN. Due to small size of the metastasis and absence of signs of progression, dynamic follow-up and hormone therapy were suggested to the patient.Conclusion. Metastatic involvement of parapharyngeal LNs is rare, especially in radioiodine-refractory PTC. They can be detected both during primary diagnosis and after the treatment during dynamic follow-up, as well as a single manifestation of PTC, which should be taken into account during differential diagnosis.
Background. Radiation-induced malignancies are one of the long-term complications of radiation therapy, which is widely used to treat some tumors. The latency period before a second tumor develops varies from 3 to 60 years. Epithelial tumors and hemoblastoses occur after low-dose radiation therapy and sarcomas after high-dose radiation therapy. Aim. To present a case of radiation-induced soft tissue angiosarcoma of the neck after the cure of Hodgkin's disease. Materials and methods. A 41-year-old patient with Hodgkin's nodular lymphoma with the lymphoid predominance of stage IIIA with involvement of the right cervical and clavicular lymph nodes, mediastinum, and abdominal lymph nodes was followed-up. In 2004 the patient underwent four cycles of polychemotherapy per ABVD regimen followed by radiotherapy of the right cervical and clavicular lymph nodes and mediastinum, with a total focal dose of 40 Gy. Results. Seventeen years after the treatment for Hodgkin's disease, including radiation therapy, the patient presented with painful swelling of the neck soft tissues in the radiation area with the transition to the anterior thoracic wall and an enlarged cervical lymph node. A lymph node dissection was performed. According to the combined positron emission tomography and X-ray computed tomography (PET/CT), histological and immunohistochemical studies, epithelioid angiosarcoma of soft tissues of the neck and thoracic wall stage IV cT2N1M1G3 with metastases to the skeleton bones, neck lymph nodes, left adrenal gland was established. Surgical treatment was not performed due to advanced disease. The patient received six cycles of polychemotherapy with doxorubicin + ifosfamide. PET/CT confirmed partial tumor regression. Conclusion. Radiation-induced soft tissue sarcoma is a late iatrogenic complication of radiation therapy for Hodgkin's lymphoma. The tumor occurred in the radiation area. PET/CT is the method of choice in diagnosing and evaluating the extent of cancer and response to treatment. Chemotherapy, as an option for complex treatment, can achieve adequate disease control when surgery is not feasible.
