A 20-year-old Japanese woman with a history of pulmonary atresia was referred to our hospital after the detection of an abnormal mass in the right lung and mediastinal lymphadenopathy. A cytological specimen obtained by transbronchial brushing indicated that the pathological diagnosis was non-small cell lung cancer. During the follow-up period, the tumor spontaneously regressed. At four months after the diagnosis, she experienced sudden bleeding from the small intestine. The histological characteristics of the small intestine tumor were compatible with the cytological characteristics of the lung tumor...

Primary hepatic malignancies are less common than metastatic diseases, but a recognition of these lesions is important for diagnosis and treatment planning. Magnetic resonance imaging (MRI) provides the most imaging information to diagnose lesions noninvasively and to narrow differential diagnoses. This paper reviews the imaging findings of chronic liver disease and primary hepatic malignancies, including hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (CCA), epithelioid hemangioendothelioma, hepatic angiosarcoma, and primary hepatic lymphoma...

Intrahepatic chlangiocarcinomas (CCs), the second most common primary malignant liver tumours, usually occur in non-cirrhotic liver, and can be classified into three types based on gross morphology: mass-forming; periductal infiltrating; and intraductal growing. Among them, mass-forming intrahepatic CCs are the most common type and characterized by homogeneous mass with an irregular but well-defined margin with peripheral enhancement on late arterial phase and delayed enhancement in central portion of tumours corresponding to the fibrous stroma...

The diagnosis of radiation-associated angiosarcoma is challenging and there are overlapping clinicopathological features between radiation-associated benign, atypical and malignant vascular lesions. It has been shown convincingly, that the majority of radiation-associated angiosarcomas are characterised by amplification and subsequent overexpression of MYC in contrast to benign and atypical vascular lesions. Given the fact that epigenetic changes play an important role in carcinogenesis and loss of histone H3K27 trimethylation (H3K27me3) has been found in a number of malignant neoplasms including malignant peripheral nerve sheath tumours, especially when associated with previous radiotherapy, we evaluated the immunohistochemical reaction pattern for H3K27me3 in 49 vascular lesions and control cases: normal skin and benign vascular lesions not associated with previous radiotherapy, radiation-associated benign, atypical and malignant vascular lesions and angiosarcomas not associated with previous radiotherapy...

One challenging feature of head and neck pathology is that a dizzying array of spindle cell lesions occurs here which ranges all the way from reactive, very aggressive forms to malignant lesions. Leiomyosarcoma is one such malignant tumour of mesenchymal origin exhibiting smooth muscle differentiation; presenting generally nonspecific signs and symptoms. Here we present a case of leiomyosarcoma in a 21 year old female patient associated with single reddish pink swelling present in the posterior right maxillary tuberosity region with moderate facial asymmetry...

INTRODUCTION: Molecular profiling (MP) has been used as a technique to identify treatment regimens for individual patient's cancer. The results of MP has been used to guide targeted therapy specific to each patient's tumor that resulted in a longer progression free survival (PFS) compared to the last conventional treatment. This study aims to provide further data to delineate the PFS of patients who get treated with targeted therapy based on MP. METHODS: A retrospective chart review was performed...

Based largely on retrospective analyses and a handful of prospective case reports, pharmacological inhibition of the beta adrenergic receptors using beta blockers has shown clinical anti-cancer efficacy in reproductive cancers, as well as angiosarcoma and multiple myeloma. Because of the potential promise of beta blockers as an adjunct to standard anti-cancer therapy, it is imperative to identify other tumor types expressing beta adrenergic (β-AR) receptors so future preclinical and clinical studies can be directed at the most promising tumor targets...

Indeterminate dendritic cell tumor (IDCT) is a proliferation of CD1a+, S100+ and langerin- histiocytes with a generally benign course. Here, we describe a case of a 90-year-old male who developed skin lesions on his scalp mimicking angiosarcoma and lymphadenopathy. He died six months after the onset of skin lesions despite of months' radiotherapy. Pathological examination ruled out scalp angiosarcoma and showed a high Ki-67 index. The appearance of skin lesions and lymphadenopathy led to challenges in diagnosis and the development of a treatment plan...

Atypical vascular lesions (AVLs) of the breast are rare cutaneous vascular proliferations that appear as flesh-colored or erythematous papules or macules in women who have undergone radiation treatment for breast carcinoma. These lesions can develop in the irradiated area up to 20 years after the radiation treatment but most commonly occur within 3 to 6 years. The general consensus agrees on the benign nature of AVLs; however, their identity as benign lesions has been a source of controversy over the years, with some investigators proposing that AVLs may be a precursor lesion to postirradiation angiosarcomas...

Acquired progressive lymphangioma (APL), or benign lymphangioendothelioma, is an unusual entity derived from vascular structures. Clinically and histopathologically it may resemble Kaposi's sarcoma and well-differentiated angiosarcoma, causing a diagnostic problem. We report an individual with APL initially diagnosed with Kaposi's sarcoma who underwent unnecessary laboratory testing. Imiquimod 5% cream stopped the progression of the lesion. Awareness of this rare entity may prevent patients from undergoing excessive testing...

Phyllodes tumors are uncommon fibroepithelial neoplasms of breast. Heterologous sarcomatous differentiation of malignant phyllodes tumor (MPT) is a rare phenomenon as shown in the literature. Herein we report a series of nine cases from a tertiary care centre in Eastern India. Patients demographic data and clinical details were obtained from the medical records. Histopathology and immunohistochemical studies were analysed and diagnosed accordingly. Out of 38 cases of PT, 13 were found to be MPT, of which 9 cases showed heterologous differentiation in the form of angiosarcoma, fibrosarcoma, undifferentiated sarcoma, extensive squamous differentiation and with lipomatous metaplasia...

We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration...

BACKGROUND: Angiosarcomas are rare and aggressive soft-tissue sarcomas. The only potential curative treatment is complete surgical excision. This study reports the outcome of isolated limb perfusion (ILP) with high-dose melphalan and tumour necrosis factor α for locally advanced angiosarcoma. MATERIAL AND METHODS: All patients who underwent an ILP for angiosarcomas between 1991 and 2016 in three tertiary referral centres were identified from prospectively maintained databases...

Angiosarcoma is an aggressive vascular sarcoma with an extremely poor prognosis. Due to the relative rarity of this disease, its molecular drivers and optimal treatment strategies are obscure. DICER1 is an RNase III endoribonuclease central to microRNA biogenesis, and germline DICER1 mutations result in a cancer predisposition syndrome, associated with an increased risk of many tumor types. Here we show that biallelic Dicer1 deletion with aP2-Cre drives aggressive and metastatic angiosarcoma independent of other genetically engineered oncogenes or tumor suppressor loss...

Cutaneous angiosarcoma (cAS) is a rare malignant neoplasm with variable clinical presentation. Although a distinct vascular tumour, cAS shares many overlapping histopathological features with other vasoformative and epithelioid tumours or 'mimickers'. cAS shows aggressive behaviour and carries a grave prognosis, thus early diagnosis is of paramount importance to achieve the best possible outcomes. Recently, several genetic studies were conducted leading to the identification of novel molecular targets in the treatment of cAS...

Scalp defect management is complicated secondary to reduced laxity in the scalp and forehead area. For reconstruction of larger defects with exposed bone and loss of the periosteal layer, free flap reconstruction is one option for single-stage surgery, although the procedure is lengthy and includes the possibility of flap loss. We successfully performed a single-stage reconstruction of a large scalp defect using a combination of artificial dermis, split-thickness skin graft, and full-thickness skin graft following wide excision of a cutaneous angiosarcoma, and present our method as one option for the treatment of large oncologic surgical defects in patients who are poor candidates for free flap surgery...

Primary pulmonary angiosarcoma is extremely rare. It is often characterized by a clinically indolent course and delayed diagnosis. To date, there have been <20 cases reported. By far, little article correlates the clinical presentation, the imaging findings with the pathology. The authors present a case of middle-aged gentleman with primary pulmonary epithelioid angiosacroma which we initially thought as tuberculosis (TB) infection. A 60-year-old gentleman, with a history of 6 months on and off blood stained sputum, was admitted for an episode of massive hemoptysis...
