The lesions of the affected muscles are usually detected during dissection after slaughter. DPM causes significant economic losses in the poultry meat industry. The purpose of this study was to investigate the gross and microscopic findings in a housereared broiler flock with DPM. In this study, the pathological findings of 12 house reared 100-120-day-old broilers with DPM were examined. All birds were clinically healthy but hemorrhages and green discoloration were detected on the pectoral muscle mass during dissection. Samples were collected from the lesioned muscles for a histopathological examination, which revealed necrosis, hyalinization, and hemorrhage. Inflammatory cell infiltration and atrophy of breast muscles was present in some cases. DPM was diagnosed based on gross characteristics and microscopic findings.
