Hypercalcemia and Bone Metastasis in a Case of Large Cell Neuroendocrine Carcinoma With Unknown Primary.

Large cell neuroendocrine carcinoma (LCNEC) constitutes a rare subset of highly undifferentiated malignancies known for their aggressive nature. Although these tumors commonly originate in the lungs and gastrointestinal tract, their potential occurrence is not restricted to specific anatomical sites, giving rise to a variety of symptoms. Notably, cases of neuroendocrine tumors (NETs) with an unidentified primary source exhibit a graver prognosis and shorter survival periods compared to those with clearly identified origins.

Aplastic Anaemia Associated with Bendamustine Therapy - A Rare Side Effect.

Introduction: During treatment for malignant lymphoma, cytopenia can develop for several reasons. This can range from mild cytopenias leading to infection and bleeding to full-blown drug-induced aplastic anaemia. While aplastic anaemia affects individuals of all genders and ages, here, we describe aplastic anaemia after chemotherapy exposure to bendamustine in a 65-year-old female with non-Hodgkin's lymphoma.

Management of acute chest syndrome in patients with sickle cell disease: a systematic review of randomized clinical trials.

Introduction: Acute chest syndrome (ACS) accounts for the highest mortality in Sickle cell disease patients. Early diagnosis and timely management of ACS results in better outcomes. However, the effectiveness of most treatment modalities for ACS management has not been established.

Renal Tubular Acidosis an Adverse Effect of PD-1 Inhibitor Immunotherapy.

Immune checkpoint blockade therapy is gaining popularity among oncologists for treatment of solid and hematologic malignancies. The widespread use of these agents resulted in increasing incidence of renal immune-related adverse events. Reported renal toxicity described so far includes acute interstitial nephritis, minimal change disease, and immune complex glomerulonephritis.

Synchronous Pulmonary Neoplasms: A Chance Occurrence or is There More Than Meets the Eye?

Primary bronchus-associated lymphoid tissue (BALT) lymphoma comprises 5% of non-Hodgkin's lymphoma (NHL) and usually has an indolent course. Synchronous primary lung cancers with BALT lymphoma are seldom seen in patients with adenocarcinoma of the lung. Synchronous squamous cell carcinoma (SCC) and BALT lymphoma is an extremely rare occurrence.

Dasatinib-induced pulmonary arterial hypertension - A rare late complication.

Dasatinib is a dual Src/Abl tyrosine kinase inhibitor approved for frontline and second line treatment of chronic phase chronic myelogenous leukemia. Pulmonary arterial hypertension is defined by an increase in mean pulmonary arterial pressure >25 mmHg at rest. Dasatinib-induced pulmonary hypertension has been reported in less than 1% of patients on chronic dasatinib treatment for chronic myelogenous leukemia.

Rasburicase-induced methemoglobinemia: The eyes do not see what the mind does not know.

Rasburicase is indicated for the prevention and treatment of tumor lysis syndrome which can be a potentially life-threatening emergency. The drug has oxidizing potential and as an adverse effect, it can convert the ferrous form of iron in erythrocytes to its ferric form resulting in the formation of methemoglobin which makes the heme component incapable of carrying oxygen. Patients with glucose-6-phosphate dehydrogenase enzyme deficiency are at high risk of methemoglobinemia from oxidizing agents.

Systemic Combination Chemotherapy in Elderly Pancreatic Cancer: a Review.

Purpose: In recent years, significant progress in survival has been achieved using systemic combination chemotherapy in patients with pancreatic cancer. However, the elderly are largely underrepresented in clinical trials, and gains made from these may not necessarily apply to this important subgroup of patients. We review the currently available data regarding contemporary combination chemotherapy regimens, including FOLFIRINOX, gemcitabine plus nab-paclitaxel, nanoliposomal irinotecan plus 5-fluorouracil and leucovorin, and gemcitabine plus capecitabine, in elderly pancreatic cancer patients.

Eosinophilia as the presenting sign in pancreatic cancer: an extremely rare occurrence.

A case of pancreatic adenocarcinoma diagnosed following work up for eosinophilia is reported. A 68-year-old female was referred to our Hematology clinic for an absolute eosinophil count of 1869 per microliter. No allergic signs or symptoms were reported.

Systemic Mastocytosis with Smoldering Multiple Myeloma: Report of a Case.

Systemic mastocytosis (SM) is a disease characterized by a clonal infiltration of mast cells affecting various tissues of the body. It is grouped into six different subtypes according to the World Health Organization classification. It is called indolent systemic mastocytosis (ISM) when there is no evidence of end organ dysfunction, while the presence of end organ dysfunction defines aggressive systemic mastocytosis (ASM).

An Exceptionally Favorable Response to Etoposide and Cisplatin.

A 66-year-old female with multiple medical co-morbidities was diagnosed with limited-stage small cell lung carcinoma (SCLC) about 11 years ago, back in 2004. The patient was treated with concomitant chemotherapy and radiotherapy, along with prophylactic whole brain radiation. She received a total of four cycles of etoposide and cisplatin.

Calreticulin Mutated Essential Thrombocythemia Presenting as Acute Coronary Syndrome.

Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterized by a clonal expansion of megakaryocytes. ET can result in both arterial and venous thrombosis. Involvement of the coronary arteries has been reported.

Bleomycin-induced flagellate erythema in a patient with Hodgkin's lymphoma - A case report and review of literature.

Bleomycin is a glycopeptide used as a chemotherapeutic agent for lymphomas, germ cell tumors, and pleurodesis of malignant pleural effusions. The pulmonary toxicity of bleomycin is well known while the cutaneous side effects are uncommon and varies from generalized hyperpigmentation, sclerodermoid changes, erythema multiformae, and gangrene to flagellate dermatosis. Here we report a characteristic but rare side effect of flagellate erythema, which developed secondary to bleomycin in a 27-year old woman with Hodgkin's lymphoma after two cycles of treatment with adriamycin, bleomycin, vinblastine, dacarbazine regimen.

A Unique Case of Malignant Pleuropericardial Effusion: HHV-8-Unrelated PEL-Like Lymphoma-A Case Report and Review of the Literature.

Primary effusion lymphoma (PEL) or body cavity lymphoma is a rare type of extra nodal lymphoma of B-cell origin that presents as lymphomatous effusion(s) without any nodal enlargement or tumor masses. It belongs to the group of AIDS related non-Hodgkin's lymphomas. First described in 1996 in HIV infected individuals who were coinfected with Kaposi's sarcoma-associated herpesvirus (KSHV) or HHV-8 virus, it was included as a separate entity in WHO classification of tumors of hematopoietic and lymphoid tissue in the year 2001.

A 61-year-old man presented with myopathy, neuropathy, and inflammatory dermatitis responsive to chronic lymphocytic leukemia treatment.

Unlabelled: The prevalence of paraneoplastic neurologic syndrome in cancer is 0.01%. Neurological syndromes can be seen in chronic lymphocytic leukemia (CLL) and mostly present as either leukemic infiltration of the central nervous system (CNS) or progressive multifocal leukoencephalopathy.

A complete resolution of sialadenitis induced by iodine containing contrast with intravenous dexamethasone infusion.

Salivary gland enlargement following the administration of iodine is an extremely rare event, and the pathophysiology of iodine-induced sialadenitis is not yet fully known. The onset of symptoms can start within a few minutes to five days after contrast administration. The course of iodine-induced sialadenitis is extremely benign, and rapid resolution of symptoms is expected without treatment.

Achievement of three year remission with bevacizumab and irinotecan in recurrent glioblastoma multiforme: a case report.

A 34-year-old man presented to the hospital with right-sided headache. He was diagnosed with GBM. He underwent resection of the tumor with placement of carmustine impregnated wafers.

A patient with multiple synchronous gliomas of distinctly different grades and correlative radiographic findings.

Background: Multiple gliomas represent approximately 2 to 5% of all high-grade gliomas which are categorized as multifocal or multicentric depending on the timing, location and pattern of spread. We present a patient with bi-hemispheric, noncontiguous, low- and high-grade gliomas proven by biopsy. She underwent surgical excision and radiotherapy, but unfortunately succumbed to her disease shortly thereafter.

Effect of parathyroid hormone and teriparatide on immune function of human adherent and non-adherent leukocytes.

Clinical data indicate that patients with hyperparathyroidism due to chronic kidney disease have abnormal immune function. We evaluated the direct effect of parathyroid hormone (PTH) and two 1-34 peptide fragments of PTH on immune function in activated leukocytes from healthy donors. IL-6 and IL-8 were measured from supernatants from phytohemagglutinin-activated non-adherent and lipopolysaccharide-activated adherent leukocytes in the presence of PTH and the two peptides using ELISA.

Pseudoleukocytosis secondary to hepatitis C-associated cryoglobulinemia: a case report.

Introduction: Laboratory tests play a central role in assessing a patient and orienting the diagnostic evaluation. We report a case where the discrepancy between the manual and automatic cell count gave a hint to the final diagnosis.

Case Presentation: A 55-year-old Caucasian man, known to have hepatitis C, was admitted with acute respiratory failure secondary to acute pulmonary edema and diffuse petechial rash of the lower extremities for the previous 2 months.

Adoptive cellular immunotherapy for the treatment of malignant gliomas.

Unlabelled: The median survival for adults with recurrent primary malignant gliomas is 56 weeks following surgery, radiation, and chemotherapy. Generally, reoperation can extend the median survival an additional 26-32 weeks. We have developed an aggressive treatment program that utilizes low doses of interleukin-2 (IL-2) combined with ex vivo activated killer cells (LAK) infused via an indwelling catheter placed into the surgical resection cavity.

Treatment of recurrent glioblastoma multiforme using fractionated stereotactic radiosurgery and concurrent paclitaxel.

Despite the progress in neurosurgery and radiotherapy, almost all patients treated with malignant gliomas develop recurrent tumors and die of their disease. Eighty-eight patients (median age 56 years) with recurrent glioblastoma (median tumor volume 32.7 cm3) were treated with noninvasive fractionated stereotactic radiosurgery and concurrent paclitaxel used as a sensitizer.
