Abstract
OBJECTIVE Co-occurring anti-tripartite motif-containing protein 9 and 67 autoantibodies (TRIM9/67-IgG) have been reported in only a very few cases of paraneoplastic cerebellar syndrome. The value of these biomarkers and the most sensitive methods of TRIM9/67-IgG detection are not known. METHODS We performed a retrospective, multicenter study to evaluate the cerebrospinal fluid and serum of candidate TRIM9/67-IgG cases by tissue-based immunofluorescence, peptide phage display immunoprecipitation sequencing, overexpression cell-based assay (CBA), and immunoblot. Cases in which TRIM9/67-IgG was detected by at least 2 assays were considered TRIM9/67-IgG positive. RESULTS Among these cases (n = 13), CBA was the most sensitive (100%) and revealed that all cases had TRIM9 and TRIM67 autoantibodies. Of TRIM9/67-IgG cases with available clinical history, a subacute cerebellar syndrome was the most common presentation (n = 7/10), followed by encephalitis (n = 3/10). Of these 10 patients, 70% had comorbid cancer (7/10), 85% of whom (n = 6/7) had confirmed metastatic disease. All evaluable cancer biopsies expressed TRIM9 protein (n = 5/5), whose expression was elevated in the cancerous regions of the tissue in 4 of 5 cases. INTERPRETATION TRIM9/67-IgG is a rare but likely high-risk paraneoplastic biomarker for which CBA appears to be the most sensitive diagnostic assay. ANN NEUROL 2023;94:1086-1101.

Abstract
Paraneoplastic cerebellar degeneration (PCD) is usually thought to have a subacute progression over several weeks. We report herein incidence and clinical features of hyperacute onset PCD, a vertebrobasilar stroke mimic. We performed a retrospective analysis of all suspected PCD cases referred to the Udine University Hospital between 2009 and 2017. Our center provides the only neuroimmunology laboratory for three provinces of the Friuli-Venezia Giulia region, Italy (983,190 people as of January 1, 2017). Inclusion criteria were (1) abrupt onset of neurological symptoms; (2) initial consideration of a vascular etiology; (3) final diagnosis of "definite PCD." We also carried out a systematic review of the literature in order to identify previous stroke-like PCD cases. Between 2009 and 2017, 24 patients received a final diagnosis of PCD. The age-standardized incidence rate of PCD was 0.22/100,000 person-years. Two cases (8.3%) had a stroke-like onset, with an incidence of 0.02/100,000 person-years. Additionally, 10 previously reported stroke-like PCD cases were identified. Among all cases (n = 12), 67% were female; median age was 51 years (range, 22-69). An associated cancer was discovered in all cases. Brain imaging was normal in most (75%) of the patients. Cerebrospinal fluid (CSF) analysis showed inflammatory alterations in 73% of the cases. Cancer treatment was more effective than immunotherapy in improving the neurological syndrome. Typical patients with hyperacute PCD are middle-aged women with normal brain imaging, inflammatory markers in CSF, and cancer. Surgery of the underlying cancer is probably the best treatment. PCD must be considered in the differential diagnosis of acute-onset ataxia and/or vertigo.

Abstract
Introduction Opsoclonus-myoclonus syndrome (OMS) is an inflammatory neurological disorder, often requiring a prompt medical evaluation. Among the diverse etiologies associated with OMS are autoimmune, infectious, paraneoplastic, and systemic diseases, and drug intoxication. Clinical Summary The case of a 36-year-old female with a disabling holocranial headache, sudden loss of consciousness, aggressive behavior, vertigo, and a personal history of somatoform disorder and major depression is presented here. After hospital admission, the patient developed sudden stereotyped movements in all four extremities and oculogyric crises compatible with OMS. Cerebrospinal fluid analysis, viral and autoimmune assays, as well as blood, urine, and bronchial secretion cultures, drug metabolite urinalysis, and tumor markers were all negative. Furthermore, brain computed tomography (CT) and brain magnetic resonance imaging, along with thoraco-abdominopelvic CT and electroencephalography, were also all negative. The patient suffered type one respiratory insufficiency after 72 h of hospitalization, requiring an endotracheal tube. After 13 days the patient suffered cardiac arrest. Necropsy was performed reporting lymph nodes with a poorly differentiated malignant neoplastic lesion, HMB-45, melan-A, vimentin, and S-100 positive, compatible with melanoma metastasis from an occult primary cancer. Discussion While the incidence of melanoma of unknown primary is between 2.6 and 3.2%, with a median overall survival ranging between 24 and 127 months, when melanoma patients develop OMS their survival is markedly decreased. Although only 5 cases of paraneoplastic OMS secondary to melanoma have been reported in the literature, all had a poor prognosis, dying within 8 months of OMS onset.

Abstract
A 58-year-old man with indolent metastatic BRAF mutant melanoma presented with several days' history of progressive ataxia and dysdiadochokinesia. His PET/computed tomography restaging scan indicated two new fluorine-18-fluorodeoxyglucose-avid mesenteric lymph nodes. Meanwhile, his MRI brain and whole spine were within normal limits. A lumbar puncture indicated an elevated protein level with a normal cell count and negative paraneoplastic antibodies. Because of the lack of an alternative differential, the diagnosis of paraneoplastic syndrome was made. He was started on high-dose corticosteroids as well as dabrafenib and trametinib. Despite this, his neurological symptoms continued to progress. Consequently, he was trialed on a course of intravenous immunoglobulin, which stabilized his symptoms. He continued to improve over several weeks, with near-complete resolution of all his neurological symptoms, and showed a complete radiological response of his disease. To our knowledge, this is the first reported case of paraneoplastic neurological syndrome with mixed neurology associated with BRAF mutant cutaneous melanoma that responded to BRAF targeted therapy.

Abstract
Described in 1962, the opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare, neurologically debilitating disorder with distinct characteristics that may begin in childhood or adult life. Although many cases remain without etiological diagnosis, others are related to neoplasms and infectious diseases. We report a 41-year-old previously healthy male with an 8-day history of headache, vertigo, nausea, vomiting, and nystagmus. After a normal brain computed tomography and lymphocytic pleocytosis in cerebral spinal fluid (CSF), intravenous acyclovir therapy was initiated in the emergency room. On the third day of hospitalization, the diagnosis of OMAS was made based on the presence of chaotic and irregular eye movements, dysarthric speech, gait instability, generalized tremor, and myoclonic jerks. In the face of his neurological worsening, ampicillin followed by nonspecific immunotherapy (methylprednisolone and intravenous immunoglobulin) was prescribed, with mild clinical improvement. After a thorough laboratory workup, the definite diagnosis of neuroborreliosis was established and ceftriaxone (4 g/daily/3 wks) and doxycycline (200 mg/day/2 mo) was administered. Toward the end of the ceftriaxone regimen, the neurologic signs substantially improved. We believe this to be the first case description of OMAS as clinical presentation of Brazilian Lyme disease-like syndrome (Baggio-Yoshinari syndrome).

Abstract
Among paraneoplastic neurologic disorders (PND), opsoclonus-myoclonus syndrome, so-called “dancing eye syndrome,” is a rare disorder combining multivectorial eye movements, involuntary multifocal myoclonus, and cerebellar ataxia. Although several paraneoplastic antibodies against postsynaptic or cell-surface antigens have been reported, usually most patients are serum antibody negative. We report a 65-year-old patient with opsoclonus-myoclonus syndrome revealing a small-cell lung carcinoma. If serologic antineuronal anti-body screening was negative, autoantibodies against glutamic acid decarboxylase (anti-GAD) were positive. Despite the specific anticancer treatment and high dose corticosteroids, the patient developed a severe and progressive encephalopathy and died 10 days later.

Abstract
Paraneoplastic opsoclonus is well described in neuroblastoma. In the adult oncologic population, opsoclonus is seen usually within the context of opsoclonus–myoclonus ataxia and is associated most strongly with small-cell lung cancer. Patients with paraneoplastic opsoclonus are often seronegative. Patients with gynecologic malignancies are known to be predisposed to paraneoplastic syndromes; however, we describe the first case of paraneoplastic opsoclonus in association with endometrial cancer.

Abstract
PURPOSE OF REVIEW The significant increase in cutaneous melanomas over the past 30 years has led to studies resulting in advances in their diagnosis, staging, surgical treatment, and adjuvant therapies. Similar approaches have been investigated in patients with far rarer malignant melanomas of the female genital tract. This review will summarize the current state of knowledge on the incidence, causes, presenting symptoms, prognostic factors, therapeutic approaches, and outcomes, site-by-site, for primary melanomas of the vulva, vagina, urethra, ovary, and the uterine cervix. RECENT FINDINGS Surgery remains the initial treatment of choice for localized melanomas of the female genital tract, with less radical, organ function preserving resections demonstrating similar control rates compared with more radical surgical approaches in vulva and possibly vaginal melanomas. Radiation therapy may play a role in the treatment of patients with close resection margins, regional nodal metastasis, or unresectable tumors. Sentinel lymph node studies, positron emission tomography and computed tomography scans for staging and evaluation of response, and adjuvant chemo or biochemotherapy warrant further investigation. SUMMARY The results of treatment for female genital tract melanomas remain poor. Although surgery remains the initial treatment of choice for localized disease, adjuvant local-regional, and systemic therapies are needed.

Abstract
Paraneoplastic cerebellar degeneration (PCD) is a rare nonmetastatic complication of a carcinoma. It is typically mediated by antibodies generated against tumor antigens. These antigens are the same proteins as expressed on Purkinje cells within the cerebellum; immune activation in the central nervous system (CNS) results in the syndrome. A 56-year-old woman with stage IIIC serous ovarian carcinoma diagnosed 3 years prior developed progressive limb ataxia. Serum anti-Yo antibodies were positive, confirming the diagnosis of PCD. Treatment with plasmaphoresis, intravenous immune globulin, and immune modulation with corticosteroids and tacrolimus was unsuccessful. Although the syndrome can be debilitating and treatment options are limited, it may also be an example of a successful host immune response in certain cases.
