BACKGROUND: Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has become a common treatment approach for disseminated appendiceal neoplasms. Systemic absorption of intraperitoneal chemotherapeutics may lead to drug-induced toxicity, most commonly neutropenia. Mitomycin C has been the most commonly used chemotherapeutic in HIPEC for the past several decades. CASE PRESENTATION: Here, we describe a rare pulmonary complication secondary to intraperitoneal administration of mitomycin C...

Diffuse-type tenosynovial giant cell tumor (TS-GCT) is categorized as a locally aggressive but non-metastasizing neoplasm according to the WHO classification. Herein, we report an extremely rare case of a 41-year-old woman who developed multiple metastases from diffuse TS-GCT with benign histological features. The patient complained of a painful buttock mass and imaging studies revealed a soft tissue tumor of the buttock and multiple pulmonary nodules. The buttock tumor was excised and the final diagnosis was extra-articular diffuse-type TS-GCT...

Pulmonary alveolar proteinosis (PAP) is classified as autoimmune, secondary, or genetic. We herein describe a 69-year-old man with autoimmune PAP, simultaneously diagnosed with myeloproliferative neoplasm (MPN). Two years after the diagnosis, the MPN progressed to acute myeloid leukemia, and the patient died from an alveolar hemorrhage during remission induction chemotherapy. Throughout the clinical course, no progression of PAP was observed, despite the progression to leukemia. There are few reports of autoimmune PAP with hematological malignancy, and this case demonstrated that an evaluation for GM-CSF autoantibodies is important for distinguishing the autoimmune and secondary forms of PAP, even if the patient has hematological malignancy...

The ribs are frequently affected by blunt or penetrating injury to the thorax. In the emergency department setting, it is vital for the interpreting radiologist to not only identify the presence of rib injuries but also alert the clinician about organ-specific injury, specific traumatic patterns, and acute rib trauma complications that require emergent attention. Rib injuries can be separated into specific morphologic fracture patterns that include stress, buckle, nondisplaced, displaced, segmental, and pathologic fractures...

Inflammatory myofibroblastic tumor(IMT)is a rare neoplasm. IMTs are found in a number of locations throughout the body, but splenic involvement is uncommon. One case of splenic IMT is described. A 42-year-old woman presented with anterior chest pain and was found to have a splenic mass by computed tomography(CT). Fluorine-18-FDG-PET showed no FDG accumulation in the spleen. Magnetic resonance imaging(MRI)at 6 months follow-up showed an increase in the size of the tumor. We performed splenectomy for a suspected malignant tumor...

Objective: The halo sign consists of an area of ground-glass opacity surrounding pulmonary lesions on chest CT scans. We compared immunocompetent and immunosuppressed patients in terms of halo sign features and sought to identify those of greatest diagnostic value. Methods: This was a retrospective study of CT scans performed at any of seven centers between January of 2011 and May of 2015. Patients were classified according to their immune status. Two thoracic radiologists reviewed the scans in order to determine the number of lesions, as well as their distribution, size, and contour, together with halo thickness and any other associated findings...

We describe a case of cardiac cavernous hemangioma with coexisting pulmonary cavernous hemangiomas and hepatic hemangioma. A 35-year-old woman who had previously received a living donor liver transplant to cure giant hepatic hemangioma was seen because of chest pain. A cardiac neoplasm and multiple pulmonary nodules were detected. The tumor was surgically removed, and biopsy specimens were taken from the lung nodules. Histopathologic examination confirmed that both lesions were cavernous hemangiomas. The patient was discharged without adverse events postoperatively...

INTRODUCTION: Primary pulmonary meningiomas (PPMs) are very rare neoplasms, and we reported the first multiple case of PPMs in 1998. Usually, PPMs are slow-growing tumors with a good prognosis. Herein, we reported a rare multiple case of PPMs with an extremely long clinical course. PRESENTATION OF THE CASE: An 84-year-old Japanese woman with a history of multiple PPMs histologically confirmed as having a right-sided slowly growing lung nodule for 20 years. In 2010, we also reported the additional clinical course in the initial case 10 years after surgery implying a benign biological nature...

The cell origin of primary pulmonary mucinous epithelial tumors includes goblet cells, tracheobronchial mucous glands, the mucous cell metaplasia of ciliated and Clara cells, etc.There are benign, low-grade malignant potential and malignant tumors in this category. The benign tumors encompass mucous gland adenoma and mucinous cystadenoma. Ciliated muconodular papillary tumors are thought to be of low grade malignant potential or uncertain malignant potential neoplasm, while colloid adenocarcinoma and mucinous adenocarcinoma are malignant tumors...

Vera P Krymskaya, Francis X McCormack
Lymphangioleiomyomatosis (LAM) is a rare, low-grade, metastasizing neoplasm that arises from an unknown source, spreads via the lymphatics, and targets the lungs. All pulmonary structures become infiltrated with benign-appearing spindle and epithelioid cells (LAM cells) that express smooth-muscle and melanocyte-lineage markers, harbor mTOR-activating mutations in tuberous sclerosis complex (TSC) genes, and recruit abundant stromal cells. Elaboration of lymphangiogenic growth factors and matrix remodeling enzymes by LAM cells enables their access to lymphatic channels and likely drives the cystic lung remodeling that often culminates in respiratory failure...

As leukemic transformation of myeloproliferative neoplasms (MPNs) worsens the clinical outcome, reducing the inherent risk of the critical event in MPN cases could be beneficial. Among genetic alterations concerning the transformation, the frequent one is TP53 mutation. Here we show that retroviral overexpression of Jak2 V617F mutant into wild-type p53 murine bone marrow cells induced polycythemia vera (PV) in the recipient mice, whereas Jak2 V617F-transduced p53-null mice developed lethal leukemia after the preceding PV phase...

BACKGROUND: Neuroendocine carcinoma of the gynecologic tract is rare and poses a significant clinical challenge because of tumor heterogeneity and lack of standardized guidelines for treatment. Ovotestis refers to the histology of a gonad that contains both ovarian follicles and testicular tubular elements. Ovotesticular disorder of sexual development occurs in fewer than 10% of all disorders of sexual development. Gonadal tumors with malignant potential occur in 2.6% of all cases of ovotesticular disorder of sexual development...

BACKGROUND: Primary cardiac angiosarcomas are rare, but they are the most aggressive type of primary cardiac neoplasms. When patients do present, it is with advanced pulmonary and/or cardiac symptoms. Therefore, many times the correct diagnosis is not made at the time of initial presentation. These patients have metastatic disease and the vast majority of these patients die within a few months after diagnosis. Currently the treatment choices are limited and there are no targeted therapies available...

MicroRNA (miRNA) is involved in the progression and metastasis of diverse human cancers, including breast cancer, as strong evidence has been found that miRNAs can act as oncogenes or tumor suppressor genes. Here, we show that miR-494 is decreased in human breast cancer specimens and breast cancer cell lines. Ectopic expression of miR-494 in basal-like breast cancer cell lines MDA-MB-231-LUC-D2H3LN and BT-549 inhibits clonogenic ability and metastasis-relevant traits in vitro. Moreover, ectopic expression of miR-494 suppresses neoplasm initiation as well as pulmonary metastasis in vivo...

Pulmonary Hamartomas (PH) are benign tumour-like lesions of lung with an uncommon occurrence and pose a diagnostic challenge on chest radiograph. Fine Needle Aspiration Cytology (FNAC) can lead to a definitive diagnosis as well as distinguishes these from malignant lung mass. Most of the patients are asymptomatic and incidentally detected on routine chest radiographs. We report a case of pulmonary hamartoma where the patient was symptomatic and a possibility of malignant neoplasm was considered until the FNAC concluded the diagnosis...
