Hemangiosarcoma Associated with Polypropylene Suture in a Cat

Abstract

Background:Sutures plays an important role in wound repair by providing hemostasis and support for healing suture. Synthetic non-absorbable like polypropylene suture materials induce minimal tissue reaction. Polypropylene has not been associated to neoplasms in domestic animals. The aim this study is to describe the first case of polypropylene suture induced hemangiosarcoma in an abdominal wall of a feline. Case: A 13-year-old female domestic shorthair cat was presented with a ventral abdominal subcutaneous mass. Clinical examination revealed a firm, rough, and irregular, approximately 6 x 4 cm subcutaneous mass involving the caudal ventral abdomen. A complete blood (cell) count (CBC) was within normal limits. Leukemia and FIV tests were negative; and the results of a chemistry panel revealed elevated creatinine (valor: 2.0 reference range: 0.5-1.9). Abdominal ultrasound revealed a large mass of mixed echogenicity in the mid-ventral abdomen cranial to the bladder, measuring approximately 6 x 4 cm in the middle line with suture deeply embedded within mass suggesting foreign body reaction or neoplasm. There was evidence of sutures (hyperechoic lines) along the caudal abdominal wall extending into the mass. Records indicated that ovariohysterectomy procedure was performed 12 years previously at the same clinic and the closure of the abdominal wall was made with polypropylene sutures. No other abdominal surgery was performed in this cat. A fine-needle aspirate of the mass and contrast-enhanced computed tomography was not performed due to owner's finance restrains. The cat was referred to surgery and the mass was excised. No evidence of metastasis was noted during surgery. Histologically, the neoplastic cells were oval to round with granular cytoplasm and vesicular nucleus and exhibited moderate cellular and nuclear pleomorphism.

Canine and feline haemangiosarcoma

“…49 Rare occurrences of HSA secondary to foreign material (such as steel staples and polypropylene suture) have also been documented in cats. 50,51 At the time of initial evaluation, HSA may be solitary, multifocally distributed within an organ or widely disseminated with metastasis. The typical gross appearance of HSA is non-encapsulated and poorly circumscribed, and friability can lead to complications associated with tumour rupture and spontaneous haemorrhage.…”

Adenocarcinoma de pulmón en felinos

“…O caso relatado por Corgozinho et al (2015), refere-se a um caso de metástase incomum de um felino onde a avaliação histopatológica concluiu a presença de um adenocarcinoma pulmonar broncogênico com metástase para pele. (Romanucci et al, 2018) descreveram um caso de adenocarcinoma pulmonar difuso de padrão micropapilar em uma felina de 12 anos.…”

“…Os sinais clínicos mais comuns estão associados ao trato respiratório e alguns sinais não respiratórios podem ocorrer, assim como claudicação relacionada à metástase nos dígitos, conhecida como síndrome "dígito-pulmonar" (Little, 2016). As neoplasias pulmonares primárias em gatos são raras, sendo bastante agressivas, com tendência a provocar metástases (Corgozinho et al, 2015).…”

Adenocarcinoma Pulmonar Felino associado com bronquite supurativa acentuada – relato de caso

“…Tumores pulmonares primários em gatos são raros. Contudo, a ocorrência vem aumentando provavelmente em decorrência do aumento da expectativa de vida, da melhora nas técnicas de diagnóstico e pelo maior contato com poluentes atmosféricos (Corgozinho et al, 2015). Gatos domésticos apresentam uma incidência superior às demais espécies, com taxa variando de 0,69-0,75% das afecções em felinos (Wilson, 2017).…”

“…Os tumores pulmonares primários são mais comuns em animais geriátricos (Lourenço et al, 2024) e os sinais clínicos na apresentação dependem da extensão do envolvimento pulmonar, da presença de metástases e da associação com síndromes paraneoplásicas (Corgozinho et al, 2015).…”
