Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...

We present a cancer nanomedicine based on acidic pH targeted gold nanorods designed for multispectral optoacoustic tomography (MSOT). We have designed gold nanorods coated with mesoporous silica and subsequently capped with chitosan (CMGs). We have conjugated pH-sensitive variant 7 pHLIP peptide to the CMGs (V7-CMG) to provide targeting specificity to the acidic tumor microenvironment. In vitro, treatment of S2VP10 and MiaPaca2 cells with V7-CMG containing gemcitabine resulted in significantly greater cytotoxicity with 97% and 96...

We report a surgical case of retroperitoneal paraganglioma. A paraganglioma is a catecholamine-producing tumor originating in the chromaffin cells of the sympathetic ganglion. It is a kind of pheochromocytoma which occurs on the outside of the adrenal gland. The patient was a 72 year old male with a history of hypertension and a pacemaker implantation. A mass in the ventral side of the right iliopsoas muscle was detected during a routine contrasting computed tomography (CT) examination for checking his pacemaker...

RATIONALE: Pulmonary spindle cell carcinoma (PSCC) is a highly malignant carcinoma that often exhibits the histopathological characteristic of cell pleomorphism. PATIENT CONCERNS: Here, we report a PSCC case in a 59-year-old woman with multiple metastases. The pathological manifestation of this case did not show high-grade pleomorphism or atypia, and was easily mimicked by other borderline or low-grade malignant tumors such as an inflammatory myofibroblastic tumor (IMT)...

BACKGROUND: Ganglioneuroma (GN) is a rare benign tumor arising from the neural crest cells. The reported incidence of GN is one per million population. As a primary retroperitoneal tumor, it constitutes only a small percentage of 0.72 to 1.6%. GN can arise de novo or as a result of maturation of a neuroblastoma either spontaneously or after chemotherapy. The most common location is the posterior paraspinal mediastinum, retroperitoneum, neck and adrenal gland. However, GN can potentially occur anywhere along the peripheral autonomic ganglion sites...

OBJECTIVE: Primary retroperitoneal mucinous tumors (PRMTs) are rare epithelial neoplasms arising in the retroperitoneal space whose pathogenesis is poorly understood. To date, only single-case reports and small case series on diagnosis and management of these tumors exist. The aim of this first-time meta-analysis was to provide more reliable data to inform the management of PRMTs. METHODS: Database searches were conducted to identify case reports and case series between the years of 1975 and 2015...

Leiomyoma of deep soft tissue is a rare type of benign smooth muscle tumor that mostly occurs in the retroperitoneum or abdominal cavity of women, and about which very little genetic information exists. In the present study, eight leiomyomas of deep soft tissue were genetically analyzed. G-banding showed that three tumors carried rearrangements of the long arm of chromosome 12, three others had 8q rearrangements, the 7th tumor had deletion of the long arm of chromosome 7, del(7)(q22), and the 8th had aberrations of chromosome bands 3q21~23 and 11q21~22...

BACKGROUND: Primary tumors in the presacral (retrorectal) space are extremely rare in adults, with an estimated incidence of 0.0025 to 0.014 in large referral centers. Congenital varieties are most common and comprise two thirds of these tumors. Primary retroperitoneal sarcomas in the pelvic region are extremely rare. We report the ultrasound and the corresponding Computed Tomography (CT) features of a rare presacral fibrosarcoma in an adult woman, in whom the diagnosis was confirmed by a CT-guided biopsy...

Most commonly, histologic transformation (HT) from follicular lymphoma (FL) manifests as a diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). Less frequently, HT may result in a high-grade B-cell lymphoma (HGBL) with MYC and B-cell lymphoma protein 2 (BCL2) and/or BCL6 gene rearrangements, also known as "double-hit" or "triple-hit" lymphomas. In the 2016 revision of the World Health Organization (WHO) classification of lymphoid neoplasms, the category B-cell lymphoma, unclassifiable was eliminated due to its vague criteria and limiting diagnostic benefit...

A 40-year-old man complaining of abdominal distention was referred to our hospital. Computed tomography of the abdomen demonstrated a very large abdominal mass with fat and calcification. The size of the mass rapidly increased from 30cm to 40cm over two weeks. The tumor was removed and diagnosed by pathological examination to be a retroperitoneal mature cystic teratoma that contained a 40-cm long, mature intestinal tract-like cyst, together with bone marrow and fat. The rapid growth of the tumor may have been caused by an increased secretion in the cyst...

BACKGROUND: While margin-negative resection remains the cornerstone of therapy for retroperitoneal sarcoma (RPS), the impact of adjuvant chemotherapy (AC) on overall survival (OS) remains poorly understood. METHODS: The National Cancer Data Base was queried for patients undergoing curative-intent resection of primary non-metastatic RPS (2004-2013). Multivariable modeling identified factors associated with AC receipt. Cox regression identified covariates associated with OS, and AC and surgery alone (SA) cohorts were matched 1:1 by propensity scores based on these covariates...

Testicular seminoma is the most common malignant tumor of the testis. It classically manifests as a painless mass. Radiologic evaluation with high-frequency ultrasonography (US) is critical for diagnosis. Seminomas are usually homogeneously hypoechoic masses at US. In challenging cases, magnetic resonance (MR) imaging may help confirm that a mass is intratesticular and provide data for local staging. Computed tomography (CT) provides valuable information for staging, including the presence and size of retroperitoneal lymph nodes...

Cystic trophoblastic tumor (CTT) is a rare testicular germ cell tumor (GCT) predominantly seen in post-chemotherapy patients. It is prognostically similar to teratoma and requires no additional chemotherapy in the absence of a nonteratomatous GCT component. We report a case of metastatic CTT in a patient with primary testicular teratoma without prior chemotherapy. Retroperitoneal lymph node metastases contained teratoma, embryonal carcinoma, and CTT. The CTT was β-hCG positive and SALL4 negative by immunohistochemistry (IHC)...

The case involves a 34-year-old who underwent surgical removal of a retroperitoneal paraganglioma adjacent to the left kidney lower pole, and visualized by CT and MRI. The (123)I-MIBG scan was positive for this lesion and, in addition, another more caudal uptake, of smaller size and intensity, was observed at L5 level. It was not considered for removal, due to its lack of morphological definition. One week after the surgery, the patient presented with difficult-to-control high blood pressure. A second (123)I-MIBG scan was performed...
