Primary pleomorphic sarcoma of the left atrium is a rare tumor. There is no actual evidence of the management of this pathological entity, so the main treatment is individualized, surgical management being the cornerstone of the treatment. We present a 78-year-old female who had a clinical picture of heart failure, documenting an atrial mass of the left atrium, with high-grade pleomorphic sarcoma revealed in histopathology. The tumor was surgical removed, with no clinical evidence of residual mass. The tumor recurred again within 3 years, to which the patient succumbed...

The patient was a 69-year-old male who had started experiencing acute-onset pain in both shoulder joints and edema of both hands and feet. His symptoms progressively worsened within 1 month. Laboratory data indicated elevated CRP and erythrocyte sedimentation rate despite the normal range of antinuclear antibodies and rheumatoid factor and normal organ function. Furthermore, imaging data of the hand indicated synovitis without bone erosions. Meanwhile, chest CT revealed a lung tumor, leading to a diagnosis of primary lung adenocarcinoma with EGFR mutation (cT2aN3M0, stage IIIB)...

A 73-year-old man, followed for prostatic hyperplasia, developed submandibular gland cancer. Initially, because of the concurrent presence of elevated serum prostate-specific antigen (PSA) and multiple bone metastases, he was clinically determined as having stage IV prostate cancer in addition to stage II submandibular gland cancer, and radical surgery for his submandibular gland cancer was performed first. However, subsequent detailed examinations of the prostate gland showed no prostate cancer, and a diagnosis of advanced submandibular gland cancer with increased PSA and multiple bone metastases was established...

The antiproliferative treatment options for neuroendocrine tumors (NET)/neuroendocrine carcinomas of the gastrointestinal tract critically depend on the proliferation rate, evaluated by immunohistochemical staining for Ki-67. According to their grading, tumors are treated with somatostatin analogs, mTOR inhibitors, or cytotoxic substances. This case illustrates downgrading of a primarily highly proliferative NET achieved by a variation of cytotoxic chemotherapy regimens, followed by a combination therapy using everolimus together with lanreotide...

We report a 74-year-old female who presented to the emergency department complaining of bruising and stroke-like symptoms. She underwent a negative stroke work-up but was found to have profoundly low platelets and splenomegaly on examination. An abdominal CT scan was ordered, showing pelvic lymphadenopathy. Lymphoma was suspected. However, subsequent bone marrow and lymph node biopsies showed no evidence of this. She was treated for immune thrombocytopenia purpura (ITP) to no avail while a lymphoma work-up continued...

Until a few years ago, metastatic melanoma had a poor prognosis with limited treatment options. These therapeutics options and thereby median survival have increased obviously over 5 years with the arrival of immunotherapeutic drugs like ipilimumab, nivolumab, and pembrolizumab. Nowadays, ipilimumab is often used in patients with metastatic melanoma. In this paper, we report a case of a 68-year-old man who developed, and eventually died of, herpes encephalitis after introducing ipilimumab as treatment for metastatic melanoma...

An elderly lady was diagnosed with primary hyperparathyroidism after being admitted to hospital with pyelonephritis and constipation. A sestamibi parathyroid scan demonstrated increased uptake in the upper mediastinum, suggesting an ectopic mediastinal parathyroid adenoma. The 4-mm adenoma was successfully removed through a mini-sternotomy incision using a gamma probe to identify the gland from the surrounding tissue. The patient made an uneventful recovery.

Brenen P Swofford, Tomislav Dragovich
Gastroesophageal cancer is the sixth leading cause of cancer-related death worldwide. The 2 most common histologies are squamous cell carcinoma and adenocarcinoma, which has seen an increase in incidence correlating with an increase in obesity in developed countries. Gastroesophageal adenocarcinoma has a preponderance to metastasize early, making it a highly lethal cancer with a low 5-year survival rate of ∼15-25%. Therefore, for the majority of patients, treatment focuses on palliation and prolongation of survival...

José Domingo Saavedra Ramírez
El linfoma de células T/natural killer extranodal ("extranodal natural killer/T-cell lymphoma", ENKL) nasal es un linfoma no Hodgkin (LNH) agresivo y poco común para el cual no se ha establecido un tratamiento de referencia claro, especialmente en el escenario de la enfermedad recidivante/refractaria. Debido a su rareza, no se han llevado a cabo ensayos aleatorizados específicamente en ENKL nasal; sin embargo, los informes de caso y las series de caso pequeñas ofrecen un conocimiento importante sobre nuevos tratamientos potenciales...

In phase II/III trials, cutaneous side effects of pazopanib were reported in less than 20% of patients, with only 1-3% being grade 3/4. We present a case of a 66-year-old man with a previous history of left nephrectomy for a stage II clear cell renal carcinoma. Approximately 18 months later, recurrent disease in the lungs, mediastinum, and left psoas and bulky abdominal/pelvic nodal metastasis were documented. He was initially treated with pazopanib 800 mg q.d. and 1 week after starting this therapy, the patient presented with palpable purpura on his ankles...

Regorafenib, an oral multikinase inhibitor, was approved in September 2012 by the US Food and Drug Administration for the treatment of patients with metastatic colorectal cancer progressing on standard therapies. Here, we describe the clinical history of a 63-year-old male patient who was treated with regorafenib in the pivotal CORRECT trial. The patient was initially diagnosed in November 2008 with nonmetastatic KRAS-mutated (exon 2, codon 12) rectal cancer. He underwent successful surgery and was treated with 5 cycles of adjuvant chemotherapy...

We report the unique case of a 61-year-old male patient with known pancreatic incidentaloma who additionally developed 3 other histologically different tumors: left sphenoid wing meningothelial meningioma, basal cell carcinoma of the occiput, and right occipital lobe glioblastoma multiforme. The latter were totally removed with a favorable clinical outcome. The patient's family history was unremarkable, and no data on any previous head and neck irradiation were found.

A 93-year-old female was transferred to the emergency ward of our hospital due to disturbance of consciousness and hypotension. Computed tomography showed bilateral pleural and pericardial effusion without evidence of tumor masses or lymphadenopathy. Cytodiagnosis of pleural effusion revealed proliferation of atypical lymphoid-like cells with pan-B surface markers. We suspected primary effusion lymphoma-like lymphoma; however, the monoclonality of these cells was not confirmed. Cytodiagnosis of bone marrow revealed lymphoma cells with monoclonal B-cell markers...

The number of patients with multiple primary malignancies has been increasing steadily in recent years. In the present study, we describe a unique case of an 81-year-old woman with 5 metachronous and synchronous primary malignant neoplasms. The patient was first diagnosed with an endometrium adenocarcinoma in 1997 and a colon adenocarcinoma in 2002. Eleven years after her colon surgery, in 2013, the patient presented with 3 other primary malignancies within a 4-month time span: an invasive malignant melanoma on the lower leg, an invasive mucinous breast carcinoma in the right breast, and a pleomorphic spindle cell sarcoma on the left upper arm...

Solitary fibrous tumor of the pleura is a rare and usually benign primary neoplasm arising from mesenchymal cells of the submesothelial tissue. We present here the case of a patient diagnosed with CD34-positive advanced malignant solitary fibrous tumor of the pleura whose disease failed to respond to combination cytotoxic chemotherapy agents, but demonstrated a prompt near-complete response to checkpoint blockade treatment using the anti-programmed death (PD)-1 monoclonal antibody pembrolizumab, based on tumor molecular profiling revealing tumoral expression positivity for both programmed death-ligand 1 (PD-L1) and PD-1...

Breast cancer is the most common tumor among women, and approximately 6% of the patients have de novo metastatic breast cancer. Occult breast cancer accounts for only 0.1-0.8% of the cases and most commonly presents with axillary lymphadenopathy. Scalp metastases are rare and have been described as a sign of progression or widespread metastatic disease. Here, we describe a rare case of de novo metastatic breast cancer to the scalp as the single site of spread and without an identifiable primary breast tumor...

NUT (nuclear protein of the testis) midline carcinoma (NMC) is a rare, poorly differentiated neoplasm with dismal prognosis. Though NMC are often metastatic by the time of presentation, cutaneous metastases have not been well described in the literature. We report a case of NMC in a patient who presented with grouped well-demarcated tender non-ulcerated erythematous nodules on the right mid-back. The lesions were initially diagnosed and treated as herpes zoster. Following failure to improve with antiviral therapy, imaging and skin biopsy revealed that the lesions were in fact cutaneous NUT carcinoma...

Ten years after his last treatment for diffuse large B-cell lymphoma, a seemingly healthy, 64-year-old man presented for his lymphoma-related follow-up. Ultrasound revealed an impressive tumor in the right adrenal gland. Due to recurrent cancer therapies in the past, this seemed highly suspicious of a second malignancy, such as primary adrenal carcinoma. Surprisingly, histology disclosed a very different but rare cause for this pseudotumorous lesion.

Docetaxel constitutes a widely used chemotherapeutic agent as a first-line treatment for several neoplastic diseases. One of the most common side effects induced by this drug is polyneuropathy, which among other symptoms can cause gait disbalance. However, in exceptional cases gait disturbances could be related to docetaxel-induced hydrocephalus, a rare event that up to the present has been overseen throughout the medical literature and should be meticulously differentiated from polyneuropathy, since its clinical features, treatment, and prognosis differ drastically...
