“…The Public Works Department of Kaohsiung City pioneered responding to extralegal construction as it pursued eco-building advocacy. Based on Kaohsiung’s Green Building Autonomous Regulations, a law initially enacted to enable rooftop solar power installations, the department launched the ‘Kaohsiung House’ programme in 2014 to expand the city’s greening intervention while fulfilling other goals: ‘To respond to decreasing population and prevailing extralegal construction in addition to climate change relief, we initiate a city-led housing reconfiguration movement inspired by a green-building trend’ (Su et al, 2016: 28). A Kaohsiung House is a green architectural prototype that incorporates rooftop solar panels, green-roof garages and vertical greenery and emphasises enlarging terraces and balconies to increase open space and amenities while providing the functions previously fulfilled by extralegal construction.…”

Despite its significance in informing inclusive political interventions in informal settlements in different political economic contexts, the urban informality literature falls short in exploring state intervention in or policy responses towards desire-based informal housing forms characterised by extralegal construction. This article uses Kaohsiung City in Taiwan as a case study to explore how the local government has collaborated with the private sector to govern the extralegal construction prevailing in community buildings. These interventions include the use of rooftop solar power systems aimed at remodelling existing buildings and green building design prototypes created to prevent future informalities. Using an urban political ecology lens, I analyse how the municipality appropriates the values and properties of solar power systems and green architecture to unite actors, relating extralegal construction to urban metabolism. I develop the concept of ‘metabolic coordination’ to show how the state coordinates actors, resources, technologies and capital to embed an internal circuit of funding flows governing extralegal construction in a larger external circuit of capital circulation consisting of growing solar photovoltaic and green housing markets. The adopted lens of urban political ecology interrogates three interrelated aspects of embedding informality in renewed urban space: municipal interventions remaking informalities, property-led greening of informalities and its negotiation, and inequality in accessing interventions. The city uses pragmatic and adaptive approaches to control extralegal construction. These approaches allow the city to leverage informality for growth and sustainability. However, the governing schemes create new forms of injustice and inequality.

Primary angiosarcoma of the kidney: case report and comprehensive literature review

et al. 2019

AbstractPurposeAngiosarcoma (AS) is an aggressive malignant tumour of endothelial origin, most frequently compelling the skin. The kidney is a rare site of primary occurrence of AS with a quite challenging diagnosis and poor prognosis, mainly due to its raw metastasising power. We described our first case of AS treatment. A comprehensive literature review in this field is also carried out.Patients and methodsWe report the case of a 56-years-old man with radiological appearance of an 11 cm poor vascularised left renal mass. The pre-operative imaging ruled out distant metastases and inferior vena cava thrombosis. Thus, after radioembolization, we performed a transperitoneal open radical nephrectomy with regional lymphadenectomy with the removal of the middle portion of the ileo-psoas muscle, followed by two lines of adjuvant chemotherapy. We analysed all the papers concerning primary kidney AS until December 2018.ResultsEstimated intraoperative blood loss was 200 mL with an operative time of 100 minutes. No postoperative complications were recorded, with the patient discharge in the 8th postoperative day. The pathological assessment showed a pT3a N0, M0 tumour compatible with AS of the kidney. An immune-histochemical study showed a vascular positive for CD31, CD34, Fli-1 with a Ki-67/Mib 1 of 50%. One month after surgery the patient began adjuvant chemotherapy with gemcitabine. After 45 days from surgery, a Computed Tomography scan showed lung and liver metastases with disease relapse in the left kidney lodge. The response to the first-line treatment was excellent, unlike the second-line, encountering a chemo-refractory disease. The cancer-specific survival was of 15 months. We included 66 cases in our review.ConclusionThis is the first case of treatment of kidney AS performed at our Institute. Our findings added new information about the unclear biology and progression of this subset of tumours, demonstrating an abysmal prognosis.

Primary vascular tumours of the kidney are rare and may pose diagnostic difficulties because of their similar clinical, morphological, and immunohistochemical features. This article summarizes the clinical and pathological features of primary renal angiosarcoma and anastomosing haemangioma of the kidney including epidemiology, genetics, and prognosis. Renal anastomosing haemangiomas are benign neoplasms characterized by anastomosing capillary-sized vascular channels. These tumours are rare, with about 75 cases reported in the literature. Most anastomosing haemangiomas are found incidentally on ultrasound, computed tomography, or magnetic resonance imaging. Common symptoms include abdominal pain, haematuria, and abdominal mass. Renal anastomosing haemangiomas are characterized by recurrent mutations in GNAQ and GNA14 genes. The prognosis of anastomosing haemangioma is excellent. Primary renal angiosarcomas are malignant tumours showing endothelial differentiation. To date, 76 cases have been described in the literature. Primary renal angiosarcomas are frequently symptomatic. The clinical features of renal angiosarcomas are similar to those of renal anastomosing haemangiomas, including abdominal pain, haematuria, and abdominal mass. Angiogenesis-related genes and vascular-specific receptor tyrosine kinases such as KDR, TIE1, SNRK, TEK , and FLT1 are upregulated in angiosarcomas. Primary renal angiosarcomas are highly aggressive neoplasms with a poor prognosis despite surgical treatment, chemotherapy, radiotherapy, or targeted therapy.
