Leiomyosarcomas of the skin and subcutis are extremely rare, however, although this diagnosis may be made based on light microscope features reminiscent of smooth muscle differentiation (Cooper and Valentine, 2002). A subcutaneous leiomyosarcoma has been reported in a cow and in a Peruvian squirrel monkey (Brunnert et al., 1990; Hanzaike et al., 1995). A dermal intravascular leiomyosarcoma has been reported in an adult cat (Jacobsen and Valentine, 2000). Solitary dermal leiomyosarcoma has been found in ferrets (Mikaelian and Garner, 2002). This paper describes a case of subcutaneous leiomyosarcoma in a pigeon.
