Abstract Background: Primary gastric melanoma (PGM) is a rare malignancy. Unlike skin melanoma which carries a definitive correlation to sun exposure, the pathogenesis of gastric melanoma is not well defined. It appears in the older age with median of 70 years and has no known risk factors. The diagnosis may be challenging due to non-specific symptoms, and endoscopy with tissue biopsy along with detailed physical examination ruling out skin and ocular lesions, and PET-CT, are the tools for establishing diagnosis. The prognosis for PGM is poor mainly due to late diagnosis. No detailed staging algorithm nor treatment protocols for PGM exists. Methods: A case series of all patients with PGM that were evaluated and managed by our surgical oncology service between 2011 and 2016. Data regarding diagnosis, imaging, pathologic evaluation and treatment protocols were collected and analyzed. Results: During study acquisition period, 3 cases with the diagnoses of PGM were identified. One patient was treated with aggressive surgery upfront, one patient was treated with more conservative surgical approach with delay from diagnosis to surgery, and one patient was not eligible for surgery due to age, medical and general condition. In 5 years of follow-up only the patient that had aggressive surgery survived. Conclusion: PGM carry very bad prognosis. We believe that aggressive surgery should be considered as the main component of the therapy plan without delay, for better clinical outcome and survival.

Abstract Objective To perform an in-depth assessment of cardiovascular and pulmonary outcomes in a series of 5 post discharged multisystem inflammatory syndrome (MIS-C) survivors. Methods Data were collected ≅1.9 month after hospital discharge at a tertiary hospital in São Paulo, Brazil. All patients (7-18 years; 3 females) fulfilled the MIS-C diagnosis according to CDC. The battery of tests included: 13 N-ammonia PET-CT imaging, standard echocardiography, brachial flow-mediated dilation using a Doppler ultrasound, cardiopulmonary exercise test, and blood markers. Results Upon PET-CT scans, two patients exhibited severe perfusion defect developed in the left ventricular cavity suggesting extensive myocardial ischemia, and one patient showed persistent mild pericardial effusion. Other two patients had endothelial dysfunction. All patients exhibited abnormal cardiopulmonary reserve during exercise (e.g., low VO2peak). Three patients had abnormal values for D-dimer and fibrinogen. Conclusion This study reveals novel pathological findings in MIS-C patients, which may help optimize treatment protocols in this condition.

Purpose: The aims of the present study were to: 1- critically assess the utility of L-3,4- dihydroxy-6-18Ffluoro-phenyl-alanine (18F-DOPA) and O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) Positron Emission Tomography (PET)/Computed Tomography (CT) in patients with high grade glioma (HGG) and 2- describe the results of 18F-DOPA and 18F-FET PET/CT in a case series of patients with recurrent HGG. Methods: We searched for studies using the following databases: PubMed, Web of Science and Scopus. The search terms were: glioma OR brain neoplasm and DOPA OR DOPA PET OR DOPA PET/CT and FET OR FET PET OR FET PET/CT. From a mono-institutional database, we retrospectively analyzed the 18F-DOPA and 18F-FET PET/CT of 29 patients (age: 56 ± 12 years) with suspicious for recurrent HGG. All patients underwent 18F-DOPA or 18F-FET PET/CT for a multidisciplinary decision. The final definition of recurrence was made by magnetic resonance imaging (MRI) and/or multidisciplinary decision, mainly based on the clinical data. Results: Fifty-one articles were found, of which 49 were discarded, therefore 2 studies were finally selected. In both the studies, 18F-DOPA and 18F-FET as exchangeable in clinical practice particularly for HGG patients. From our institutional experience, in 29 patients, we found that sensitivity, specificity and accuracy of 18F-DOPA PET/CT in HGG were 100% (95% confidence interval- 95%CI - 81-100%), 63% (95%CI: 39-82%) and 62% (95%CI: 39-81%), respectively. 18F-FET PET/CT was true positive in 4 and true negative in 4 patients. Sensitivity, specificity and accuracy for 18F-FET PET/CT in HGG were 100%. Conclusion: 18F-DOPA and 18F-FET PET/CT have a similar diagnostic accuracy in patients with recurrent HGG. However, 18F-DOPA PET/CT could be affected by inflammation conditions (false positive) that can alter the final results. Large comparative trials are warranted in order to better understand the utility of 18F-DOPA or 18F-FET PET/CT in patients with HGG.

Background:Giant cell arteritis (GCA) may affect the aorta and the large aortic branches and lead to dissections and aortic aneurysms. Tocilizumab (TCZ) treatment has the capacity to control aortic inflammation as has been demonstrated by CRP normalization and imaging data. However, limited data are available on the histopathological findings obtained from patients who underwent surgery because of aortic complications during TCZ treatment.Objectives:We report on 5 patients with aortitis who were treated with TCZ and developed aortic complications.Methods:We describe a retrospective case series of patients with GCA treated with TCZ, who presented in our clinic between 2011 and 2019. Three patients underwent surgery. Histopathologic examination was performed in specimen from all of them.Results:Five female patients were diagnosed with GCA (4/5) or Takaysu arteritis (1/5) involving the aorta, all them diagnosed by MR angiography and/or FDG PET CT scan. Three patients (one with aortic aneurysm, one with dissection) underwent surgery after having been treated with TCZ for seven weeks, nine months and four years, respectively. Imaging before surgery showed remission on MRI and/or PET-CT in all cases. At the time of surgery, all patients showed normalized CRP and ESR values. Histopathological evaluation of the aortic wall revealed infiltrates, consisting predominantly of CD3+CD4+ T cells. Enlargement of pre-existing aneuryms was observed in the other two patients 10 weeks and 4 months after discontinuation of TCZ, respectively. Both patients were not eligible for surgical intervention and died during follow-up.Conclusion:Our case series suggests that during treatment with TCZ, regular imaging is necessary in this patient population to detect development of structural changes such as aneurysms or dissections. Despite treatment, residual inflammation might persist which could contribute to eventual aortic complications.Disclosure of Interests:Andrea Rubbert-Roth Consultant of: Abbvie, BMS, Chugai, Pfizer, Roche, Janssen, Lilly, Sanofi, Amgen, Novartis, Peter Karl Bode: None declared, Thomas Langenegger: None declared, Claudia Pfofe: None declared, Thomas Neumann: None declared, Olaf Chan-Hi Kim: None declared, Johannes von Kempis Consultant of: Roche

68Ga-DOTATOC represents a useful tool in tumor contouring for radiosurgery planning. We present a case series of patients affected by meningiomas on who we performed 68Ga-DOTATOC positron emission tomography (PET)/CT pre-operatively, a subgroup of which also underwent a post-operative 68Ga-DOTATOC PET/CT to evaluate the standardized uptake value (SUV) modification after Gamma Knife ICON treatment in single or hypofractionated fractions. Twenty patients were enrolled/included in this study: ten females and ten males. The median age was 52 years (range 33–80). The median tumor diameter was 3.68 cm (range 0.12–22.26 cm), and the median pre-radiotherapy maximum SUV value was 11 (range 2.3–92). The average of the relative percentage changes between SUVs at baseline and follow up was −6%, ranging from −41% to 56%. The SUV was reduced in seven out of 12 patients (58%), stable in two out of 12 (17%), and increased in three out of 12 (25%), suggesting a biological response of the tumor to the Gamma Knife treatment in most of the cases. 68Ga-DOTATOC-PET represents a valuable tool in assessing the meningioma diagnosis for primary radiosurgery; it is also promising for follow-up assessment.

Abstract Introduction Heterotopic ossification of large joints is a commonly seen and described entity in Burn survivors. We have observed a rather uncommon phenomenon in a series of 4 Burn survivors who presented to our Burn center for scar treatment and open wounds many years after their injuries. A chronic, small, splinter-like subcutaneous irritation led to open wounds and infections in their burn scars. A similar condition is known as dystrophic calcinosis cutis in the dermatologic literature, but caused by calcium metabolism changes in otherwise healthy skin. Methods The demographics and history of illness was documented in all 4 patients. A literature review was performed. The calcified bone-like irritant was removed surgically in all patients, sometimes in more than one location. Pathologic evaluation was performed on the removed specimen. Strategies leading to healing of the wounds were evaluated. Results Four publications were found addressing this phenomenon in Burn scars, all case reports. All of our patients had undergone curettage of the lesions by a dermatologist in the past without resolution. All lesions were excised surgically and proved to extend subcutaneously far more extensively than the visible skin lesion. X rays proved not helpful in preoperative assessment of the extent. All wounds healed after the irritant was removed. Conclusions All lesions appeared to have formed along tendon or fascia remnants underneath the burn scars, exerting pressure on the overlying epithelium which eventually led to breakdown and necrosis. This finding prompted the term “heterotopic cutaneous ossification”. Chronic tension and inflammation were assumed in the etiology, rather than calcium metabolism abnormalities or systemic connective tissue disease, which were not present in these patients. Research is needed to establish the prevalence, cause, and prevention of this condition in Burn survivors.

Introduction: Topical corticosteroids (TC) are useful for treatment of various dermatological conditions in all age groups. Due to its cosmetic application TCs misuse is intertwined with fairness creams in our colour conscious society where people are obsessed with fair colour.   Aims and Objectives: To find the clinical presentations of steroid induced rosacea like-dermatitis on the face and to evaluate the purpose behind misusing TCs on the face.   Materials and methods: Descriptive prospective questionnaire-type case series study was approved by Institutional Ethical Committee of BPKIHS which involved 205 patients diagnosed as Steroid Induced Rosacea who consulted Dermatology OPD between March to June 2017.   Results: Among 205 patients enrolled, majority were from second to fourth decade (87.31%) of their life and maximum being females I.e. 91.2%. Around 97% of the study population were unaware of side effects of TCs. Most patients use Mometasone fuorate (58.04%) for melisma (88.29%). Friends acted as source of prescription (29.75%), followed by Pharmacist (24.88%) & Beauty centers (20%). Dermatologists prescribed TCs in only 6.34% cases. Sun exposure was identified as the triggering factor for steroid induced rosacea in 73.17% patients. Cheek was the commonest site involve in 92.19%, followed by forehead (65.36%), perioral area (46.83%), and chin (9.75%). Mixed type of lesions was the commonest lesion found in 52.20% patients, followed by diffuse facial erythema (36.09%), & telangiectasia (33.17%).   Conclusion: TCs misuse in the younger people for the sake of fairer skin with little or no knowledge about the adverse effects of this medication should be stopped.

Abstract Introduction Extraparotid Warthin tumor (WT) is a very rare entity, especially when synchronous with oral cancer (OC). Objective The present study presents a case series of extraparotid WTs detected in the surgical specimen of patients treated for OC. Methods From 2007 to 2016, 336 patients were operated for OC in our institution. Neck dissection was performed in 306 patients. Results In the 306 patients operated for OC whose necks were dissected, unexpected WTs were observed in 4 surgical neck specimens. In 3 cases, extraparotid WTs were responsible for tumor, node, metastasis (TNM) overstaging before surgery. Conclusion Extraparotid WTs may be discovered during neck dissection in ∼ 1% of OC patients, and they may mimic neck metastasis, especially in positron-emission tomography/computed tomography (PET/CT) imaging.

We present four cases of intravascular large B-cell lymphoma (IVLBCL), a rare malignancy with poor outcomes. The exclusive presence of lymphoma cells in blood vessels leads to a heterogenous presentation and poor diagnostic yield with traditional initial diagnostic tools. Timely diagnosis and treatment can lead to improved outcomes.
