Abstract

ABSTRACT Lymphoma is the most common lymphoproliferative disorder in cats. However, cutaneous lymphomas are uncommon in this species and can be classified as epitheliotropic or non-epitheliotropic. Epitheliotropic lymphomas are typically of T-cells and have tropism for epidermis and/or adnexal epithelium. Non-epitheliotropic lymphomas can be of either T-cell or B-cell and involve predominantly the dermis. The present study describes a case of multifocal cutaneous anaplastic large T-cell lymphoma. The skin nodules were multiple and variable in size, alopecic and erythematous in appearance and randomly distributed. Immunohistochemistry revealed positivity for the CD3 antigen, consistent with T-lymphocytes. This neoplasm should be remembered whenever multiple cutaneous nodules are observed in cats.

猫皮肤间变性大T细胞淋巴瘤一例报告
摘要淋巴瘤是猫最常见的淋巴增生性疾病。然而,皮肤淋巴瘤在该物种中并不常见,可分为上皮样或非上皮样。嗜上皮性淋巴瘤通常是T细胞,对表皮和/或附件上皮具有嗜性。非上皮性淋巴瘤可以是T细胞或B细胞,主要累及真皮。本研究描述了一例多灶性皮肤间变性大T细胞淋巴瘤。皮肤结节多发,大小不等,外观脱发、红斑,随机分布。免疫组织化学显示CD3抗原阳性,与T淋巴细胞一致。只要在猫身上观察到多个皮肤结节,就应该记住这种肿瘤。
