587, p less then  0.0001) and mEVs were strongly associated with PD (r = 0.919, p less then  0.0001), but gender had no effect on plasma mEV levels (p = 0.667). Parasite density was also exponentially related to patient delay. Gender (p = 0.667) had no effect on plasma mEV levels. During periods of low parasitaemia (PD = 72h), mEVs were 0.93-fold greater than in uninfected controls. As 75% (49/65) of patients had low parasitaemia levels (20-500 parasites µL-1), close to the detection limits of microscopy of Giemsa-stained thick blood films (5-150 parasites µL-1), mEV quantification by NTA could potentially have early diagnostic value, and raises the potential of Pf markers in mEVs as early diagnostic targets. © 2019 The Author(s).

A 60-year-old male with a 1-month history of right-sided facial pain and failed antibiotics therapy underwent head and neck CT scan that revealed a tonsillar mass. Tonsillar biopsy revealed squamous cell carcinoma, HPV-16 positive. PET-CT scan showed a significant activity in the right tonsillar mass along with prominent right level 2 lymph nodes and no distant disease. Definite surgery was deferred and he underwent 7 weeks of radiation therapy with concurrent weekly Cisplatin. PET scan 8 weeks later showed significant improvement in large right palatine tonsil mass; however, a new FDG-avid cardiac mass of right ventricle. An echocardiogram showed an ejection fraction of 59% and a large mass in the apical portion of the right ventricle. Cardiac MRI confirmed a 9 cm right ventricular mass. Complete resection of the cardiac mass was unsuccessful; a partial tumor debulking provided adequate sample for pathologic examination, which was consistent with metastatic squamous cell cancer, p16+, clinical-stage T4aN1M1. Surgical intervention was not performed; instead, he received a palliative radiation therapy to his right-sided cardiac mass with concurrent Keytruda immunotherapy. Unfortunately, the evening of successfully completing his last therapy, he was found unresponsive and subsequently expired. Although tonsillar carcinoma metastasis to the myocardium is rarely coupled with its atypical presentations, clinicians should consider early echocardiogram evaluation for possible metastatic disease so as to provide early interventions. © 2019 The Author(s).

Unlike the stomach or the ileum, the jejunum is a rare site for primary extranodal lymphomas, given the scarcity of lymphoid tissue. Due to its location, inflammation in the jejunum may not be visualized on routine imaging or endoscopy, making jejunal lymphoma difficult to diagnose. Case Description We present a case of a 90-year-old male with 1 week of intractable emesis, initially thought to be due to viral gastroenteritis. His symptoms never improved and he underwent serial CT imagings in addition to esophagogastroduodenoscopy. MRTX849 manufacturer A stomach biopsy and a diagnostic paracentesis did not reveal any malignant cells, but a CT enterography revealed significant jejunal inflammation with obstruction. After a month of hospitalization, a jejunal biopsy was obtained, which showed proliferation of neoplastic B cells. He was ultimately diagnosed with primary jejunal diffuse large B cell lymphoma. Discussion Chemotherapy and surgical resection are typically the definitive treatment for extranodal lymphoma. Clinicians, however, must carefully consider the patient's functional and nutritional statuses before offering such interventions. This case was a diagnostic challenge and demonstrated a rare GI malignancy's convoluted mimicking nature. © 2019 The Author(s).

LCH lesions in the skull place the adjacent central nervous system (CNS) at risk for involvement, which can manifest as central diabetes insipidus (CDI) when there is infiltration of the hypothalamic-pituitary axis. We present a case of a 39-year-old female who presented with polyuria and polydipsia for 1 year and left-sided hearing loss, gait instability, and nystagmus for 5 days. She was found on laboratory evaluation to have CDI and underwent left cortical mastoidectomy for a destructive peripherally enhancing mastoid lesion seen on MRI brain. Pathology revealed CD1a and S100+ LCH and the patient was subsequently discharged to begin outpatient chemotherapy with vinblastine and prednisone. The patient's CDI was diagnostic of CNS involvement, making her LCH multisystem through the infiltration of both the skull and hypothalamic-pituitary structures. As CDI can be seen in up to 25% of single-system LDH, and up to 50% of multisystem cases, radiologic studies to evaluate for osteolytic skull lesions must be considered as part of the evaluation for LCH when CDI has been diagnosed. © 2019 The Author(s).

Case Summary A 55-year-old man with stage 1 follicular lymphoma and GERD on omeprazole presented with symptoms suggesting carcinoid syndrome. The only positive finding on workup was a markedly elevated level of chromogranin A and no carcinoid tumor was identified. Omeprazole was discontinued, following which his symptoms resolved and chromogranin A levels returned to normal. To the best of our knowledge, no symptoms have been previously reported in association with PPI-induced hyperchromograninemia. Discussion The reliability of chromogranin A as a marker for neuroendocrine tumors is of growing concern. The reasons for the associated symptomatology in this case are unclear but could involve physiologic effects of chromogranin A breakdown products. The role of pharmacogenomics in PPI metabolism is discussed as a potential explanation for the significant hyperchromograninemia. Conclusion The phenomenon of PPI-induced hyperchromograninemia is highlighted for providers especially in the context of neuroendocrine tumor diagnosis and surveillance.
