ABSTRACT A male 15-year-old captive Siberian tiger (Panthera tigris altaica) developed pelvic limb hypermetry over the past 10 years. Recently, an ulcerated black nodule located caudally to the right ear was observed. The animal was submitted to surgery for removing the tumor, but died during anesthetic recovery. At necropsy, another infiltrative nodule was observed caudally to the right ear. Histologically, both nodules corresponded to melanocytic neoplasia, varying from heavily pigmented to amelanotic, with metastasis to mediastinal lymph nodes, spleen and lung. Lipofuscinosis and corpora amylacea were histologically observed in the central nervous system. Macroscopic and histologic findings confirmed the diagnosis of skin metastatic melanoma in a captive adult Siberian tiger.

Multiple sclerosis (MS) is an autoimmune disabling disease of the central nervous system, and can lead to a wide range of symptoms. Although the most common form of MS is relapsing-remitting, most of the patients also will develop disability in the future due to the natural course of the disease.1,2 The disease onset mostly occurs in 27 years of age.3 Therefore, considering the symptoms and complications of the disease, it can virtually affect the whole life of the patient. Unfortunately, there is not any accurate study of the opinions of patients with MS regarding their illness. However, in the daily work of treatment, one of the well-known cases of severe discomfort expressed by patients is the fear of future disability. This issue is aggravated when a person starts to lose abilities. When the patient experiences disability in walking and a decrease in his/her daily activities, thinking about the future becomes one of his/her major concerns. Most patients express these concerns in their visits. However, a patient who has other abilities such as poetry, writing a story, or painting, can more effectively portray concerns. The painting reported here is the allegorical view of a patient about her disability. The patient is a 37-year-old woman who has had MS for 15 years. Her illness started with the right eye optic neuritis. She has had six attacks during this period and, after 9 years, her disease entered the secondary progressive phase. Her symptom in this stage was the weakness of the right lower extremity, which was gradually deteriorating such as difficulty in walking. Now, she is unable to walk without help. This disability has affected all aspects of her life, and has greatly diminished her quality of life. She has been interested in drawing since childhood, and has drawn as a non-professional artist. One of her paintings reported here (Figure 1), according to the patient herself, reflects her perception and grief over her progressive disability. She believes that she should say goodbye to her ability and good days of the past. She painted herself as someone (when she could walk unrestrictedly) moving away along with a balloon
