Breast angiosarcoma may occur de novo, or as a complication of radiation therapy, or chronic lymphedema secondary to axillary lymph node dissection for mammary carcinoma. Both primary and secondary angiosarcomas may present with bruise like skin discoloration, which may delay the diagnosis. Imaging findings are nonspecific. ⋯ Follow up: no further complications were detected during regular check-ups. However, 12-years later, patient reported significant changes at breast region which was exposed to radiation during treatment of original tumour. In this article, we describe the clinical presentation, imaging and pathological findings of secondary angiosarcoma of the breast after radiotherapy (Fig. 2, Ref. 26).

Soybean (Glycine max), mistletoe (Viscum album) and red clover (Trifolium pratence) have been argued to have anti-cancer effects. In the present study it was aimed to investigate possible effects of these plant extracts on the activities of DNA turn-over enzymes, namely adenosine deaminase (ADA) and xanthine oxidase (XO) in cancerous and non-cancerous gastric and colon tissues. ⋯ Our results suggest that aqueous soybean, mistletoe and red clover extracts may exhibit anti-tumoral activity by depleting hypoxanthine concentration in the cancer cells through XO activation, which may lead to lowered salvage pathway activity necessary for the cancer cells to proliferate in the cancerous colon tissue. Some foods like soybean, mistletoe and red clover may provide nutritional support to medical cancer therapy through inhibiting and/or activating key enzymes in cancer metabolism (Tab. 4, Ref. 33).

The aim of this study was to evaluate the effect of dexmedetomidine (100 µg/kg-ip) on liver ischemia and reperfusion (I/R) in rats. ⋯ All the results suggest that dexmedetomidine has beneficial effects on liver ischemia/reperfusion stress (Tab. 1, Fig. 2, Ref. 49).
