Multidetector CT findings of primary pleural angiosarcoma : a systematic review, an additional cases report

Background To demonstrate and analyze the relatively common imaging findings in this rare primary pleural angiosarcoma (PPA). Case presentation Three cases of PPA, proven by video-assisted thoracic surgery biopsies are retrospectively reviewed. Patients were all male. Age ranges from 65 to 75 years old age (mean; 69). Major chief complaints were dyspnea and chest pain. One has a history of colon cancer, the other has a tuberculosis history and the other has no known history. Multidetector chest CT and PET CT were all done. Immunohistochemical studies were performed including CD31, CD34, or factor VIII-related antigen, vimentin, and cytokeratin. We also review the literatures on recently published PPA. All masses were from 1 to 10 cm. All three patients had multiple pleural based masses, which were ovoid in shape with relatively sharp margin in unilateral hemithorax. Multiple small circumscribed pleural masses are limited in the pleural space in two patients, whereas two, huge lobulated masses about up to 10 cm were present with pleural and extrapleural involvement in one patient. In two patients with pleural mass only, multiple pleural masses were only seen in parietal pleura in one patient and were in both visceral and parietal pleura in one patient. Pleural effusion were found in one side in one patient and in both sides in one patient. One angiosarcoma was arised from chronic tuberculotic pleurisy sequelae. All pleural masses are heterogenous with irregular internal low densities in all patients. Hematogenous metastases were found in liver, vertebra, rib in one patient, and were in lungs with mediastinal lymph node metastases in the other patient. Three patients survived for longer than 3months after diagnosis, but continued to deteriorate rapidly. Two patients underwent chemotherapy after surgical excision, and the other one with multiple metastases treated chemotherapy after CT-guided biopsy, but eventually all died. As a result of comparative analysis of a total of 13 patients’ images including 10 cases previously published, there was pleural effusion in all except 2 cases. Conclusions PPA were all necrotic without any vascularized enhancing nature, and manifested as unilateral circumscribed or localized pleural-based masses.

Prognostic Analysis of Different Metastatic Patterns in Invasive Intraductal Papillary Mucinous Neoplasm: A Surveillance, Epidemiology, and End Results Database Analysis

Objective. To evaluate the impacts of different metastatic patterns on the prognosis of patients with invasive intraductal papillary mucinous neoplasm (IPMN). Materials and Methods. All patients who were diagnosed with invasive IPMN in the Surveillance, Epidemiology, and End Results SEER database (2010–2015) were included in this study. They were grouped according to different metastatic patterns. Kaplan–Meier analysis and log-rank test were used for the comparison of their survival rates. The hazard ratio (HR) with 95% confidence interval (CI) was analyzed using the Cox proportional-hazards model. Results. A total of 2264 cases were included in this study. The most common metastatic site was the liver. The patients with the nonorgan metastasis demonstrated the best survival outcomes, while those with multiple metastases showed the worst survival outcomes. As compared to the patients with isolated liver metastasis, those with isolated lung and other organ metastases showed better overall survival rates and tumor-specific survival rates. The patients with liver, lung, multiple, and other organ metastases or of age >60 years were the independent predictors of poor prognosis. Conclusions. The patients with isolated lung and other organ metastases demonstrated better survival outcomes as compared to those with isolated liver metastasis. The patients with nonorgan metastasis demonstrated the best survival outcomes, while those with multiple metastases showed the worst survival outcomes. Further studies are needed to determine a highly selected subset of patients, who might benefit from surgery or chemotherapy.

Multiple endocrine disorders manifested as gynecomastia in a patient with renal pelvis cancer

A 95-year-old man was diagnosed with left pelvis cancer which presented with rapid tumor growth, multiple metastases, and bilateral tender gynecomastia. Elevated serum human chorionic gonadotropin(hCG), prolactin, estradiol, and progesterone were detected. The patient’s condition rapidly deteriorated and he passed away.

Májsejtspecifikus kontrasztanyaggal végzett MR-vizsgálat alkalmazása colorectalis eredetű májáttétek reszekciója előtt

Összefoglaló. Bevezetés: A colorectalis eredetű májáttétek (CRCLM-ek) kuratív célú kezelésében elsődleges a sebészi reszekció. A műtét előtt különböző képalkotó vizsgálatok végezhetők, az egyik ilyen speciális vizsgálat a májsejtspecifikus kontrasztanyaggal végzett MR-vizsgálat. Célkitűzés: Tanulmányunkban a májsejtspecifikus kontrasztanyaggal végzett MR-vizsgálat helyét és szerepét vizsgáltuk a májsebészeti gyakorlatban colorectalis áttétes betegek esetében. Módszer: Az Uzsoki Utcai Kórház Sebészeti-Onkosebészeti Osztályán 2017. 01. 01. és 2019. 12. 31. között CRCLM miatt májreszekcióra kerülő betegek adatait elemeztük. Retrospektív módon vizsgáltuk a betegek általános sebészeti és onkosebészeti paramétereit, a képalkotó diagnosztikai eredményeket, a műtéti adatokat és a patológiai leleteket. Eredmények: 132, CRCLM miatt operált betegből 73 szoliter áttét (55%), míg 59 beteg (45%) többszörös áttét miatt került műtétre. 94 betegnél (71%) történt májsejtspecifikus MR-vizsgálat. Szoliter áttét esetén 60%-ban, multiplex áttétek esetén 85%-ban történt májsejtspecifikus MR-vizsgálat (p = 0,02). A szoliter áttétes betegek 8%-ában, míg a multiplex áttétes betegek 39%-ában mutatott további áttétet a májspecifikus kontrasztanyaggal végzett MR-vizsgálat (p = 0,001). A betegek 5%-ában igazolódott fals pozitivitás és 6%-ában fals negativitás a májsejtspecifikus MR-vizsgálat során. 264 góc vizsgálata alapján a májspecifikus kontrasztanyaggal végzett MR-vizsgálat szenzitivitása CRCLM esetén 95%-os, míg pozitív prediktív értéke 93%-os volt vizsgálatunkban. Következtetés: A májsejtspecifikus kontrasztanyaggal végzett MR-vizsgálat hasznos diagnosztikai módszer a CRCLM-ek sebészi reszekciója előtt. Leginkább többszörös áttétek esetén, preoperatív szisztémás onkológiai kezelést követően, illetve más képalkotó vizsgálaton igazolt eltűnt áttét esetén javasolható az alkalmazása. Orv Hetil. 2021; 162(50): 2010–2016. Summary. Introduction: Liver resection is the only curtive treatment option of colorectal cancer liver metastases (CRCLMs). While different diagnostic modalities are available before surgery, a specific diagnostic tool is the liver-specific contrast-enhanced MRI. Objective: The purpose of this study was to evaluate the role of liver-specific contrast-enhanced MRI before resection of colorectal liver metastases. Method: Patients with CRCLM, resected at the Department of Surgical Oncology, Uzsoki Teaching Hospital, between 01. 01. 2017 and 31. 12. 2019 were enrolled in our study. Clinical data, diagnostic, intraoperative and pathological findings were analyzed in a retrospective setting. Results: 132 CRCLM patients were resected in this period, 73 patients had solitary (55%), and 59 patients (45%) had multiple metastases. Liver-specific contrast-enhanced MRI was performed in 94 patients (71%). 60% of the patients with solitary and 85% of the patients with multiple CRCLM had liver-specific contrast-enhanced MRI (p = 0.02). Compared to other modalities, liver-specific contrast-enhanced MRI showed additional metastases in 8% of the patients with solitary, and in 39% of the patients with multiple metastases (p = 0.001). Liver-specific contrast-enhanced MRI had a 5% false-positivity and a 6% false-negativity rate. 264 leasions were analyzed, and the sensitivity of the liver-specific contrast-enhanced MRI was 95% with a predictive positive value of 93%. Conclusion: Liver-specific contrast-enhanced MRI is a useful diagnostic tool in CRCLM patients before liver resection. It is highly recommended in the case of multiple metastases, after preoperative chemotherapy and in the case of disappearing metastases. Orv Hetil. 2021; 162(50): 2010–2016.

Sertoli cell tumor of the testis causing intracranial metastasis two years after orchiectomy. Report of a rare case and review of the literature

Sertoli cell tumor of the testis (SCTT) accounts for less than 1% of all testicular tumors with only 10% of cases exhibiting malignant behavior. In the present report, a case of malignant SCTT causing multiple metastases in a 32-year-old man is described. After being diagnosed and treated for bone and lymph nodes metastases, the patient presented with a brief history of worsening headaches and visual impairment. A head MRI demonstrated an extra-axial tumor located in the right fronto-parietal junction exhibiting avid contrast enhancement and leptomeningeal involvement. To the best of the authors’ knowledge, this represents the second case of intracranial metastasis from SCTT described to date.

CS-7 A case of Lymphomatoid granulomatosis with skin, lung, and intracranial lesions due to multicentric development

Introduction: LYG is very rare tumor and composed of large EB-positive B cells and reactive T cells. In this study, we experienced a case of LYG with multiple intracranial, cutaneous, and pulmonary masses. We report the pathogenesis and pathophysiology of LYG, including a discussion of the literature. case: A 69-year-old female presented with a growing lump in her lower back that had been present for several years. Six months later, she was found to have multiple masses in her lungs and intracranial region and underwent surgical removal for diagnostic purposes. Intraoperative findings: The tumor was substantial, reddish to grayish-white in color, and the margins of the tumor were whitish and hard, with some areas that could not be detached. Pathological findings: There were no atypical lymphocytes, and a small number of EBER-positive cells were observed. IgVH PCR: IgVH PCR was performed on the skin lesions and intracranial lesions, and bands of different sizes were detected, suggesting that the IgVH clone was present in the polyclonal region. Finally, we diagnosed LYG grade 1. discussion: EB-associated lymphoproliferative disease can lead to polyclonal reactive growth or monoclonal neoplastic growth depending on the balance between morphology and host immunity. The results of IgVH PCR suggest that the skin lesions did not cause multiple metastases, but rather that the enlargement of the skin lesions triggered intracranial and pulmonary lesions in an allo-centric manner. The results of IgVH PCR suggested that the skin lesions did not cause multiple metastases, but rather that the skin lesions grew to cause intracranial and pulmonary involvement in an other-centric manner.

Atypical bilateral ventilation/perfusion mismatches in an asymptomatic patient suffering from metastatic thyroid cancer

Background Pulmonary embolism is indicated by ventilation/perfusion (V/P) mismatches in ventilation/perfusion scintigraphy. However, other pathologies may also evoke segmental or lobar mismatches. Thus, diagnosis can be difficult in asymptomatic patients with equivocal clinical presentation. Case presentation We present a case of multiple bilateral pulmonary ventilation/perfusion mismatches in a poorly differentiated thyroid cancer patient. Exact diagnosis was difficult, as the patient was asymptomatic and pulmonary embolism is commonly unilateral in tumour patients and not typical for thyroid cancer. External pulmonary artery compression by aortic aneurysm, multiple metastases or additional bronchopulmonary malignancies were considered as differential diagnosis. After unilateral pulmonary and hilar metastasectomy, perfusion normalised on the operated side. Pulmonary perfusion defects due to pulmonary artery compression by hilar metastases were finally diagnosed. Pulmonary embolism was deemed unlikely due to the left-sided post-operative normalisation, persistence of right-sided V/P mismatches, and the lack of clinical symptoms. Conclusion Pulmonary artery compression may mimic pulmonary artery embolism in lung perfusion scintigraphy and should be considered in bronchopulmonary tumour patients with hilar metastases and unilateral ventilation/perfusion mismatches affecting a complete lobe or even lung. Following the presented case, also bilateral segmental and subsegmental mismatches in patients with hilar metastases from non-bronchopulmonary cancer entities should be carefully evaluated.

An Extensive Case of Merkel Cell Carcinoma due to Fright of COVID-19

Merkel cell carcinoma (MCC) is a subtype of nonmelanoma skin cancer (NMSC) with increasing incidence. Clinically, MCC resembles other far less-aggressive NMSCs, and the pathogenesis is still not understood completely. Rapid diagnosis and treatment are essential to improve overall survival. We present a case report of a 74-year-old female, who had noticed a rapidly growing, oozing tumor on her right flank. She was hesitant to contact the dermatology ward where she had regular checkups as she was afraid of contracting COVID-19. This was in the beginning of the COVID-19 pandemic. At presentation, she had a large exophytic MCC on her right flank and multiple metastases. The disease was at a late stage, and palliative care was the only treatment option left. With this case, we wish to report a rather uncharacteristic location and size of an MCC tumor and suggest that fear of the pandemic and the COVID-19 lockdown has impacted dramatically on attendance of symptomatic patients.

Clinical and morphological case of lung cancer with generalized metastases to the internal organs

Lung cancer has occupied a leading position in the structure of cancer morbidity and mortality throughout the world for many years. Lifetime diagnosis is often difficult due to the absence of any defining signs of cancer, and it is quite difficult to track the first signs of lung cancer. This is justified by the fact that the lungs are completely devoid of nerve endings and the presence of 26% of healthy lung tissue is sufficient to provide the body with the required amount of oxygen. Prolonged absence of clinical manifestations leads to late seeking medical help, which is often fatal. Description of the case. A 65-year-old patient who died at home was referred for a postmortem examination. The sectional study revealed signs of peripheral cancer of the right lung with multiple metastases in all fields of the lungs, in the liver, spleen, pancreas, with no metastases in the lymph nodes. Histological examination revealed extensive areas of tumor tissue, consisting of solid structures with glandular differentiation of tumor tissue of various sizes and shapes, with round and oval atypical nuclei. There was a pronounced polymorphism of cells, with a large number of pathological mitoses. Thrombi were detected in the lumen of the segmental and small branches of the pulmonary artery. Thus, the presented case is of particular interest for practicing physicians due to the fact that with adenocarcinoma of the lung, there were no characteristic metastases to the lymph nodes. Hematogenous metastasis occurred with the development of generalized metastases to the internal organs.
