ABSTRACTCutaneous lymphoma was clinically, histopathologically and immunohistochemically detected in a 1.5-year-old male peafowl in this case. Histopathologically, intradermally located diffuse cutaneous lymphoma composed of atypical lymphoblastic cells and exhibiting a pattern of follicular development was diagnosed on the right buccal area of the peafowl. Positive reaction with CD3 and CD20 antibodies confirmed the diagnosis immunohistochemically.Key Words: Peafowl, cutaneous lymphoma, immunohistochemistry, CD3, CD20 ÖZETBİR TAVUS KUŞUNDA KUTANOZ LENFOMA OLGUSUBu olguda; 1,5 yaşındaki erkek tavus kuşunda klinik, histopatolojik ve immunohistokimyasal yöntemlerle kutanöz lenfoma belirlendi.
