Thrombocytopenia is a frequent complication of cancer may be due to a variety of causes including malignancy itself, acute disease processes, or cancer therapy. Systemic cancer therapy is the most common cause of thrombocytopenia in cancer patients observed nearly two-thirds of patients with solid tumors. Thrombocytopenia with traditional chemotherapy agents is most frequently the result of megakaryocyte cytotoxicity. Oxaliplatin is a platinum derivative commonly used in gastrointestinal malignancies and is associated with drug-induced immune thrombocytopenia...

Background: Chronic neutrophilic leukemia (CNL) is an extremely rare myeloproliferative neoplasm (MPN). Due to the difficulty in its diagnosis, the diagnostic criterion was just recently revised in 2016. CNL is defined as: A clonal disorder with sustained primary neutrophilia, with normal neutrophil maturation, that does not meet other MPN criteria, as well as no identifiable mutations of the PDGFRA, PDGFRB or FGFR1 or PCM1-JAK2 genes, and, either, the presence of a CSF3R mutation, or if absent, the presence of sustained neutrophilia (> 3 months), splenomegaly and no other identifiable cause of reactive neutrophilia including the absence of a plasma cell neoplasm, or, if present, demonstration of myeloid cell clonality by cytogenetics...

Intracardiac metastases in the absence of inferior vena cava involvement is a rare occurrence in patients with metastatic renal cell carcinoma (mRCC). There is limited evidence regarding the efficacy and safety of standard treatment modalities for mRCC patients with intracardiac metastases. Presence of intracardiac metastases is known to indicate poor prognosis and may potentially increase risk of treatment-related complications. Recent advances in RCC management have integrated nivolumab, a programmed death-1 (PD-1) receptor inhibitor, as a preferred treatment option in the second-line setting after failure of prior anti-angiogenic therapy; or in combination with ipilimumab, an anti-Cytotoxic T-lymphocyte antigen-4 antibody as first-line therapy for intermediate to poor risk patients with mRCC...

Background: Continuous therapy targeting human epidermal growth factor receptor 2 (HER2) is recommended until disease progression for patients with HER2-overexpressing (HER2+) metastatic breast cancer. Prolonged stable disease has been observed with such maintenance therapy using trastuzumab, but the frequency of these cases remains low. Whether combined maintenance therapy with two different HER2-targeted agents could improve the rates of durable progression-free survival compared with trastuzumab alone is under investigation...

Angioinvasive lymphomatoid papulosis (LyP) type E is a rare variant characterized by angiocentric and angiodestructive features with CD30+ CD8+ lymphocyte infiltration. In rare cases, LyP type E is concomitant with mycosis fungoides, but there is no English report that describe LyP type E developing from parapsoriasis en plaque. In this report, we described a case of angioinvasive LyP (type E) developing from parapsoriasis en plaque, in which we employed immunohistochemical staining for the investigation of its pathomechanisms...

Background: Thyroid carcinoma generally has a good prognosis. The main focus of current research on thyroid carcinoma is to increase the accuracy of preoperative diagnosis of thyroid nodules. When the result of fine needle aspiration biopsy (FNAB) is indeterminate, clinicians often have doubts in determining the surgical management. Objective: Protein BRAF expression analysis can help improve the accuracy of FNAB and optimize the management of differentiated thyroid carcinoma...

Background: Carcinoma ex pleomorphic adenoma (CXPA) is a rare histologic subtype of lacrimal gland and submandibular gland cancer. Currently, there is no standard treatment for metastatic CXPA, although some case reports have explored the role of targeted agents in chemotherapy. A few histopathologic analyses have shown that some of these tumors overexpress human epidermal growth factor receptor-2 (HER2), suggesting a potential role for HER2-based therapy. We report here two cases of metastatic CXPA that were treated with trastuzumab-based chemotherapy (IRB approved) with rapid and significant responses...

Among the differential diagnoses that should be considered in acute respiratory failure (ARF) are infectious processes, autoimmune diseases, interstitial pulmonary fibrosis, and pulmonary neoplasia. Timely diagnosis of lung neoplasia is complicated in the early stages. An opportune diagnosis, as well as the specific treatment, decrease mortality. ARF occurs 1 in 500 pregnancies and is most common during the postpartum period. Among the specific etiologies that cause ARF during pregnancy that must be considered are: (1) preeclampsia; (2) embolism of amniotic fluid; (3) peripartum cardiomyopathy; and (4) trophoblastic embolism...

Introduction: Due to the beginning of the use of immunophenotypic and cytogenetic techniques, new nosological forms of lymphoproliferative diseases have appeared over the past few decades. According to the WHO classification (2008), today there are more than 50 known lymphoproliferative diseases. Case Presentation: We present the case of a 51-year-old man with lymphoproliferative syndrome. Our patient underwent morphological and immunohistochemical investigations of biopsy materials from the right inguinal lymph node...

Background: Lymphomatosis cerebri (LC) is a unique form of primary central nerves lymphoma (PCNSL), which presents as diffuse infiltration of lymphoma cells characteristically in the white matter rather than tumor formation. However, the involvement of central nervous system (CNS) is unclear because of the lack of contrast enhancement. Case Presentation: We treated a 53-year-old woman with LC and brain lesions resembling neuro-Behcet's disease. She had a past history of acute uveitis and current symptoms of somnolence and gait disturbances progressing for one month...

With advances in new cytotoxic drugs and molecular-targeted drugs, the prognosis of patients with metastatic colorectal cancer (mCRC) has improved. However, physicians often hesitate to administer intensive standard regimens to elderly patients with mCRC. Recently, first-line regimens that are effective in and well-tolerated by patients who are not eligible for intensive chemotherapy have been established. However, the therapeutic strategies to adopt after the failure of first-line treatment for patients who are not eligible for intensive chemotherapy remain unclear...

Background: Acute myeloid leukemia (AML) is the most common leukemia in adults. According to the French-American-British (FAB) system, monocytic leukemia is classified as M5. Myeloid sarcoma further occurs in 3-5% of AML. This is defined as an extramedullary tumor of myeloid cells in the lymph nodes, soft tissues, periosteum, bone, central nervous system (CNS), spinal cord, intestine, mediastinum, prostate, uterus, or ovaries. Case Presentation: Here, we describe the case of a 29-year-old female who presented with fever, swelling of gums, neck pain, and weakness, which had persisted for 1 week...

Mantle cell lymphoma (MCL) is a rare form of non-Hodgkin lymphoma (NHL), responsible for 2.8% of all NHL cases within the United States. The majority of patients with MCL present with advanced disease, 10-20% of which have extra-nodal involvement at diagnosis. The gastrointestinal presence of lymphoma can lead to gastrointestinal perforation, resulting in significant morbidity from peritonitis and sepsis while prolonging hospitalizations and delaying treatment. In this case we discuss a 55-year-old male with newly diagnosed MCL who developed peritonitis 9 days after initiation of dose reduced rituximab due to gastrointestinal perforation...

Although crizotinib shows marked antitumor activity in anaplastic lymphoma kinase (ALK) rearrangement-positive non-small-cell lung cancer (NSCLC) patients, all treated patients ultimately develop resistance to this drug. Isolated central nervous system failure without progression at extracranial sites is a common progression pattern in ALK rearrangement-positive NSCLC patients treated with crizotinib. Here, we report the success of crizotinib combined with whole-brain radiotherapy in an ALK rearrangement-positive NSCLC patient who developed leptomeningeal carcinomatosis and progression of multiple brain metastases...

Advanced head and neck squamous cell carcinoma, after locoregional treatment and multiple lines of systemic therapies, represents a great challenge to overcome acquired resistance. The present clinical case illustrates a successful treatment option and is the first to describe the use of photodynamic therapy (PDT) with Redaporfin, followed by immune checkpoint inhibition with an anti-PD1 antibody. This patient presented an extensive tumor in the mouth pavement progressing after surgery, radiotherapy, and multiple lines of systemic treatment...

Two randomized studies of symptom monitoring during chemotherapy or during second line treatment and follow-up via web-based patient-reported outcomes (PROs) was previously demonstrated to lengthen survival. We are presenting here a patient with advanced and recurrent lung cancer who was followed for 4 years by PROs for relapse and adverse events detection. We report how the web-mediated follow-up helped to detect dangerous pulmonary embolism, relapse and pseudo-progression to immunotherapy by self-reported symptom tracking and specific algorithms triggering notifications to medical team, allowing early management of events...

Clear cell carcinoma is the most common form of renal cell carcinoma (RCC). Metastatic RCC is poorly responsive to treatment and has a bleak prognosis. Newer systemic agents have improved outcomes. Furthermore, their interaction with radiation treatment (RT) may provide further therapeutic options. RCC is considered to be radioresistant, however we report the case of a patient with progression on targeted therapy and immunotherapy who achieved a substantial and sustained local, and possibly abscopal, response to low dose palliative radiation therapy...

Photo-recall phenomenon is a rarely recognized adverse event of chemotherapeutic agents. The physiopathology of this entity is unclear. We have reported a 56-year old breast cancer patient with severe photo toxicity recalled 5 months after the initial sunburn by one course of adjuvant docetaxel treatment. However, being given right diagnosis and proper managements the patient could be able to complete her adjuvant chemotherapy according to the planed time schedule, without any delay. Our case may be explained by the theory that long-lived memory T-cells may remember former skin damage and cross-react with cytotoxic drugs...

Background: Esophageal cancer (EC) with unexpected metastasis (UM) to unusual sites have been increasingly reported. EC with metastasis in general has a very high mortality and morbidity rate, and those with UM to unusual sites present another specific field that needs to be further studied in order to understand and manage the presentation. An extensive systematic review was recently completed regarding this field which identified characteristics and findings concerning patients with EC with UM sites...

Standard therapy for radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC) is multi-targeted kinase inhibitors (m-TKIs), represented by sorafenib and lenvatinib. One of the main target molecules of m-TKIs is vascular endothelial growth factor receptor (VEGF-R). m-TKIs are known to cause adverse reactions such as hypertension and proteinuria as a class effect. In particular, proteinuria is thought to result from vascular endothelial damage and podocytopathy in glomeruli, and the development of thrombotic microangiopathy (TMA) has been reported for VEGF inhibitors...
