[First description of canine leproid granuloma in Germany: 2 case reports].

Using cytology, histopathology, and DNA sequencing the diagnosis of canine leproid granuloma (CLG) was made in 2 dogs. The dogs were presented with nodular skin lesions on the head and pinnae. CLG is caused by nontuberculous mycobacteria that have not yet been finally classified. To date, this disease has been reported in Australia, New Zealand as well as North and South America, however no case reports have been published in Germany until now. In both cases, a combination of surgery and long-term drug administration (rifampicin, clarithromycin, doxycyclin and local application of clofazimin) was chosen and successfully eliminated the granulomas.
