“…In humans, thymomas usually present in the fourth to fifth decade but can occur at all ages without sex predisposition [3]. In dogs and cats, thymomas are also found in older animals [4], and they are rarely reported in avian species and have only been documented in an African grey parrot ( Psittacus erithacus ),[5] a finch (unspecified species), [6] domestic chickens,[7,8] a budgerigar ( Melopsittacus undulatus ), [9] and a Java sparrow ( Padda oryzivora ) [10]. …”

Thymoma is a primary mediastinal neoplasm arising from or exhibiting differentiation towards thymic epithelial cells, typically with the presence of non-neoplastic lymphocytes. A 13-year-old male Mynah bird (acridotheres tristis) was presented for evaluation of a 2.3 × 1.5 × 1.0 cm mass in the left ventrolateral cervical region. The clinical signs, radiology, cytohistopathology and immunohistochimy findings related to the thymoma are presented. These findings indicated that the tumor was a type AB thymoma according to the World Health Organization (WHO) and veterinary classification. Thymomas are rarely reported in avian species and this is the first report in a Mynah bird.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1159525819982779.

“…An epithelial thymoma was reported in budgerigar (Melopsittacus undulates) (9). Another case of thymoma was reported in female Java sparrow (Padda oryzivora) (10). Another case of thymoma was reported in five chickens associated with thymoma caused by Marek's diseases virus infection (11).…”

A 2-year-old rooster local breed suffered from anorexia, emaciation with an abnormal large mass in the lateral side in the cervical region was attended to Veterinary Teaching Hospital belong to College of Veterinary Medicine, Mosul University. After physical examination a movable and friable mass was recognized in the cervical region, the case sends for surgical intervention. Gross examination of the removed mass showed a friable, pale, will capsulated with hemorrhagic areas. Microscopically, the mass included three types of tumors. Squamous cell thymic carcinoma characterized by the presence of keratin pearl. Lymphoma that characterized by atypical polymorphic lymphocytes, vesicular nucleus, and pyknotic nucleoli, while cytoplasm appears eosinophilic to granular with ill-define borders. Lipoma which appears as irregular shape of adipocytes that lack their nucleus, with scattered infiltration of pyknotic lymphocytes. This is the first pathological report of mixed tumor of the thymus gland in rooster that composed from squamous cell thymic carcinoma, lymphoma and lipoma.

“…Lymphoma has been described in birds in the orders Anseriformes, Charadriiformes, Columbiformes, Ciconiiformes, Galliformes, Passeriformes, Psittaciformes, Strigiformes, Sphenisciformes, Pelecaniformes, and Struthioniformes. [6][7][8][9][10][11][12][13][14][15] Thymomas, classified histologically as either epithelial or lymphocytic, are rarely reported in avian species and have only been documented in an African grey parrot (Psittacus erithacus), a finch (unspecified species), domestic chickens, budgerigars (Melopsittacus undulatus), Java sparrow, 16 and a red-tail common mynah bird (Acridotheres tristis). 17 Thymoma is the main differential diagnosis for thymic lymphoma and can be easily confused because they are sometimes accompanied to a greater or lesser degree by small lymphocytes.…”

“…17 Thymoma is the main differential diagnosis for thymic lymphoma and can be easily confused because they are sometimes accompanied to a greater or lesser degree by small lymphocytes. 16 In this Java sparrow, the diagnosis of lymphoproliferative diseases was straightforward, but further investigation into the type of lymphocyte malignancy and to differentiate thymoma from thymic lymphoma requires special staining techniques. Immunocytochemistry using monoclonal antibodies against cell-surface glycoproteins is frequently used to differentiate between B-and T-lymphocyte malignancies in dogs, 18 and similar assessments can be used in birds.…”

A 4-year-old Java sparrow (Lonchura oryzivora) was diagnosed with thymic lymphoma based on the results of histopathologic evaluation and immunohistochemical staining of a Tru-cut biopsy sample. The bird was treated with chlorambucil (2 mg/kg PO) twice per week for the first 18 weeks, and the mass size, activity level, appetite, bowel function, and body weight were monitored weekly. At week 19, the bird became ill and anorexic, and the chlorambucil treatment was discontinued. The neoplasm grew rapidly during weeks 20 and 21, and the chlorambucil treatment was resumed at week 23. At week 28, the bird's overall condition worsened and the chlorambucil treatment was discontinued because no additional reduction in mass size had occurred. At week 29, prednisolone (2.2 mg/kg) was administered orally every 12 h for 31 weeks. At week 61, the patient became acutely ill, exhibiting anorexia and a decreased level of physical activity, and the owner elected to euthanatize the bird. This is the first report of long-term management of thymic lymphoma in a Java sparrow.
