RETRACTED ARTICLE: Cervical type AB thymoma (Mixed) tumour diagnosis in a mynah as a model to study human: clinicohistological, immunohistochemical and cytohistopathological study

Abstract

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.

“…In some studies, the fine needle aspiration cytology specimens contained many individual bizarre, multi-nucleated, and/or giant cells having hyperchromatic pleomorphic nuclei, prominent nucleoli, and relatively abundant cytoplasm, admixed with numerous mitotic figures in a hemorrhagic or inflammatory background in human. A small amount of sheet-like or three-dimensional clusters of malignant cells coexisted [ 26 - 30 ].…”

Long-term Management of Thymic Lymphoma in a Java Sparrow (Lonchura oryzivora)

“…[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. 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.…”

“…3,14,15,19,20 Also, a cervical type AB thymoma (mixed) tumor was diagnosed in a mynah with the help of clinicohistologic, immunohistochemical, and cytohistopathologic study. 17 In humans, cytokeratin profiles are used to differentiate thymic lymphoma from thymoma. 1 A positive treatment response was reported in an umbrella cockatoo (Cacatua alba) with B-cell lymphoma, 3 and chlorambucil treatment failed in a great horned owl (Bubo virginianus) with disseminated T-cell lymphoma.…”
