Malignant melanoma of the rectum is an extremely rare disease. It typically presents in the fifth or sixth decade predominantly in female sex. The first symptoms are nonspecific such as bleeding, anal mass or pain. A timely diagnosis of melanoma is made even more difficult due to lack of obvious pigmentation and histologically amelanotic. Anorectal malignant melanoma spread along submucosal planes and are often beyond complete resection at the time of diagnosis. Prognosis is very poor. We present a rare case of malignant melanoma of rectum in a 21-year-old male, who was diagnosed at advanced stage, and a case of malignant melanoma in a 50-year-old male, who underwent abdominoperineal resection with permanent colostomy. Anorectal malignant melanoma is difficult to diagnose and prognosis is poor.

Abstract Urban landscapes have the potential to conserve wildlife. Despite increasing recognition of this potential, there are few collaborative efforts to integrate ecology and conservation principles into context-dependent, spatial and actionable design strategies. To address this issue and to encourage multi-disciplinary research on urban human–wildlife interactions, we ask the following questions. To what extent should design and planning actions be aligned with urban ecology in the context of a compact city? How can wildlife conservation meet the seemingly conflictual demands of urban development and public preference? To answer these questions, we refer to the relevant literature and a number of design projects. Using the compact tropical city of Singapore as a case study, we propose 12 design strategies. We encourage designers and planners to strengthen the links between wildlife and urban dwellers and promote wildlife conservation within cities.
