Bowenoidin-situ carcinoma 皮肤原位癌 Bowenoid in-situ carcinoma (also termed multicentric squamous cell carcinoma in-situ) is a neoplastic transformation of keratinocytes that remains localized above the epithelial basement membrane. Lesions appear most commonly on haired skin of the head, neck and proximal limbs. Lesions are often multifocal, well- circumscribed, hyperpigmented, hyperkeratotic macules and plaques that may be ulcerated and crusted. Non-sun-induced lesions are considered to have a viral etiology, and papillomavirus DNA was identified in the majority of lesions in one study. In 2016, Felis catus papillomavirus type 2 (FcaPV-2) was isolated from aggressive, disseminated BISCs in two unrelated Devon Rex cats. High FcaPV-2 copy numbers and FcaPV-2 gene expression were detected in the majority of lesions, including those in the pulmonary parenchyma. 皮肤原位癌(也称为原位多中心鳞状细胞癌)是位于表皮层基底膜上方的角质细胞的一种肿瘤性转化。病变最常见于头部、颈部和四肢近端的有毛皮肤上。病变通常是多灶性,界限清楚,色素沉着,角化过度的斑和斑块,可能是溃疡和结痂。非日光诱导的病变要考虑病毒性病因,在一项研究中,在大多数病变中确定有乳头状瘤病毒DNA。2016年,从两只无血缘关系的德文莱克斯猫的侵袭性弥散性BISCs(皮肤原位癌)中分离出猫科动物乳头状瘤病毒2型(FcaPV-2)。在大多数病变中,包括肺实质病变中,FcaPV-2拷贝数和FcaPV-2基因表达较高。 |
Cutaneous horns 皮角 Cutaneous horns are cylindrical masses of hard keratin that extend from the center of paw pads (Figure 1). In some affected cats, horns have also been found on the nasal planum and eyelids. Cutaneous horns have been reported in FeLV- negative cats; however, they were located just ventral to the nail bed on the digital pads only. The diagnosis of cutaneous horns can be made on FeLV status and clinical presentation alone, although histopathology is confirmatory. Immunohistochemical staining for FeLV antigen gp70 is positive in cases associated with FeLV infection. 皮角是从爪垫中心向外延伸的圆柱形硬角质块(图1)。有的患猫在鼻面和眼睑上也发现了皮角。有报道称,在FeLV阴性的猫身上有皮角;然而,它们仅位于甲床腹侧的爪垫上。皮角的诊断可以根据FeLV的状态和临床表现单独作出,尽管组织病理学可以证实。FeLV抗原gp70免疫组化染色阳性。 |

Feline infectious peritonitis 猫传染性腹膜炎 Feline infectious peritonitis (FIP) is an almost invariably fatal systemic disease caused by mutation of a feline enteric coronavirus (FCoV) combined with an ineffective immune response. The disease is associated with disseminated pyogranulomatous vasculitis. Cutaneous lesions are rare. In four published reports, small (2–9 mm) variably erythematous and crusted papules were present over the trunk, neck and proximal forelimbs. Cytologic and histopathologic samples revealed pyogranulomatous inflammation.In one of these cases, FCoV infection was confirmed on biopsy sections using immunohistochemistry to identify viral antigens within macrophages. 猫传染性腹膜炎(FIP)是一种由猫肠道冠状病毒(FCoV)突变引起的全身性致死性疾病。该病与弥散性脓性肉芽肿性血管炎有关。皮肤病变很少见。在四份已发表的报告中,在躯干、颈部和前肢近端上存在小的(2~9毫米)多样的红斑和结痂性丘疹。细胞学和组织病理学检查显示脓性肉芽肿性炎症,其中一例在活检切片上用免疫组织化学方法确定巨噬细胞内的病毒抗原,从而确诊FCoV。 |
