A dermatofibroma is associated with the dimple sign; by applying lateral pressure, there is a central depression of the dermatofibroma. Although typical dermatofibromas cause little or no discomfort, itching and tenderness can occur. Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms. [5]
The cemento-ossifying fibroma is hard and fibrous, most frequently seen in the jaw or mouth, sometimes in connection with a fracture or another type of injury. Other fibromas: chondromyxoid fibroma , desmoplasmic fibroma , nonossifying fibroma , ossifying fibroma , nuchal fibroma , collagenous fibroma , fibroma of tendon sheath , perifollicular ...
Lip reconstruction may be required after trauma or surgical excision. The lips are considered the beginning of the oral cavity and are the most common site of oral cancer. Any reconstruction of the lips must include both functional and cosmetic considerations. The lips are necessary for speech, facial expression, and eating.
Another autoimmune skin disease which can occur in dogs is vitiligo. In addition to humans, vitiligo can be found in a variety of animals, including cats, horses, and dogs.

Many times an implantable Doppler probe or other devices can be installed during surgery to provide better monitoring in the post-operative period. The Doppler probe can be removed before discharge from the hospital. Usually the harvest of a "free flap" is performed in such a fashion to cause the least amount of disability.
Oral submucous fibrosis (OSF) is a chronic, complex, premalignant (1% transformation risk) condition of the oral cavity, characterized by juxta-epithelial inflammatory reaction and progressive fibrosis of the submucosal tissues (the lamina propria and deeper connective tissues).
