Lipoma is a benign tumor composed of proliferation of mature fat cells interspersed by fibrous connective tissue, blood vessels and muscles, delimited by a thin capsule. Although it represents a mesenchymal neoplasm most common human body, are rare occurrences in the oral cavity. Presents clinical and histopathological variables that do not alter their prognosis. The pathogenesis is still uncertain, although some authors consider heredity and endocrine disorders as possible causes. Occurs with greater prevalence in obese people, although their metabolism is completely independent of the normal body lipid metabolism. The clinical diagnosis of oral lipoma is the view of a nodular mass, soft, asymptomatic, flat surface, without ulceration and limited growth. The continuing growth of the lesion may cause difficulty in chewing, speech, dental adaptation and change in facial aesthetics of the patient, requiring surgical excision of the lesion. The final diagnosis is by histopathological examination. Aims to present a literature review and clinical cases of a retrospective study of 61 cases of lipomas diagnosed in pathological service between 1978 and 2009, among the 10 573 reports during that same period. It emphasizes the special cases of large lipomas of the maxillofacial region, and the importance of early diagnosis of these lesions. A dental surgeon should be able to diagnose lipomas in an early stage in the maxillofacial area avoiding a massive growth of these lesions.

The transitional cell carcinoma is usually located in the trigone region of the bladder, and shows nonspecific clinical signs of the lower urinary tract such as hematuria, strangury, pollakiuria and urinary incontinence. The urethral and ureteral obstructions occur in some cases. Etiological factors such as endogenous and iatrogenic have been listed as the cause of disease. The objective of this report is to describe the process and treatment of two cases of transitional cell carcinoma presented simultaneously in two dogs, mother and daughter, that showed hematuria and post-renal azotemia, both with tumor in the trigone of bladder. After partial cystectomy ureteroneocistostomia, the diagnosis of transitional cell carcinoma was confirmed by histopathological analysis of bladder tissue. Patients received firocoxib as adjuvant to surgery. It is concluded that the surgical procedure associated with the use of specific anti-inflammatory COX-2 provided a better quality of life in both patients.
