RESUMO
ABSTRACT: Cutaneous reactive angiomatoses encompass a spectrum of conditions driven by underlying occlusive vasculopathy. We present 2 cases of reactive angioproliferation in the context of end-stage renal failure (ESRF) manifesting as painful cutaneous ulceration. The first case demonstrates histologic features of diffuse dermal angiomatosis. The second case illustrates a nonspecific pattern of vascular proliferation which does not conform to any of the classically described subtypes, therefore reinforcing the concept of a spectrum of histopathologic changes in reactive angioproliferations. Diffuse dermal angiomatosis has been described in ESRF alone and in association with calciphylaxis, a life-threatening condition. Recognizing the patterns of reactive angioproliferation in the context of ESRF therefore has clinical relevance. Earlier identification may facilitate mitigation of risk factors and improve prognosis.

Enteropathy-associated T-cell lymphoma (EATL) is a rare but potentially fatal cause of diarrhoea and weight loss. EATL commonly presents with abdominal pain, diarrhoea and weight loss, but can also present with complications such as bowel obstruction and perforation. It is a tumour of intraepithelial lymphocytes that occurs in a relatively young population. It is the most common neoplastic complication of coeliac disease, but can occur with no prior diagnosis of coeliac disease. This case demonstrates the difficulties that can be faced in diagnosing this disorder, particularly when there is no preceding history of coeliac disease. Early diagnosis is of utmost importance in order to start treatment before the effects of malnutrition increase the risk of complications from chemotherapy. Hence awareness of the condition among general medical physicians, to whom it will often present first, is essential. However, even with prompt diagnosis, outcomes for this condition remain poor.
