Use of a carbon dioxide laser to treat ceruminous gland hyperplasia in a cat

Practical relevance: Chronic otitis can be one of the most frustrating diseases to manage for a small animal practitioner. While it occurs less commonly in the cat than the dog, it is no less challenging. The purpose of this review is to discuss the common and uncommon causes of chronic otitis in the cat within the clinical framework used for diagnosis and treatment. The focus is on diseases that affect the ear canal, rather than those restricted to the pinnae. Clinical challenges: Otitis is multifactorial, which complicates management. A common clinical mistake is to focus solely on treating the infection present. Only by addressing all factors will a clinician successfully control chronic otitis. For the purposes of this review, the authors have adopted the established model of separating primary, predisposing and perpetuating causes of otitis. Primary factors are those that directly cause otitis (inflammation); predisposing factors are those that put the patient at risk for development of otitis; and perpetuating factors are those that result in ongoing clinical signs of otitis or that prevent clinical resolution. Audience: This review is aimed at veterinarians who treat cats and particularly those with an interest in feline dermatology and otology. Equipment: While many practitioners rely on a hand-held otoscope, a video-otoscope can be very helpful for the diagnosis and treatment of chronic otitis. Evidence base: This review presents up-to-date information regarding the diagnosis and treatment of chronic otitis in cats, with emphasis on the most recent peer-reviewed literature.

“…Apesar da ablação com laser ser a mais recomendada conforme citado na literatura consultada, visto que reduz os danos teciduais assim como a formação de cicatrizes e deformação do pavilhão auricular (Boord, 2006;Duclos, 2006;Corriveau, 2012;Miller et al, 2013), a remoção dos cistos com bisturi elétrico também se mostrou eficaz. De acordo com os tutores do animal, não houve recidiva dos nódulos nos últimos três anos.…”

“…No entanto, criocirurgia, excisão cirúrgica com bisturi elétrico ou cauterização química também são eficientes (Boord, 2006). Sem a remoção completa do cisto as chances de recorrência aumentam consideravelmente (Boord, 2006;Duclos, 2006;Corriveau, 2012).…”

Neste trabalho, os autores relatam o caso de um gato Persa, macho, de cinco anos e meio de idade, atendido na Cidade do Rio de Janeiro apresentando nódulos auriculares diagnosticados por histopatologia como cistomatose ceruminosa. Por tratar-se de uma afecção pouco comum, de etiologia desconhecida e fácil resolução, os autores objetivaram divulgá-la, descrevendo os principais sinais clínicos e tratamentos. Como terapia, foi realizada a excisão cirúrgica dos cistos com bisturi elétrico e não houve recidiva nos últimos três anos. Sugere-se que os cistos benignos podem malignizar, além de dificultarem o asseio do conduto auditivo levando ao acúmulo de cerúmen e, consequentemente, a infecções secundárias (otite externa) por proliferação microbiana.

“…The nomenclature for this condition can be confusing, and terms such as sebaceous or ceruminous cysts, 5–7,14,15 apocrine cystadenoma, ceruminous cystadenoma, 8 apocrine cysts, apocrine hidrocystomas, 8,13,16 sweat gland cysts of the skin, 5,6,11,12 melanotic ceruminous cysts, 17,18 ceruminous gland adenomas, ceruminous gland cysts, 19 ceruminous gland hyperplasia, 19,20 ceruminous cystomatosis 21,22 and epitrichial cystadenomas 15 have all been used. We have previously used the term ‘cystomatosis’ in abstracts.…”

Objectives This study aimed to understand epidemiological factors associated with feline cystadenomatosis, including signalment and papillomavirus PCR status. Cystadenomatosis is an uncommon condition primarily involving the ceruminous and apocrine skin and ear glands. Methods This was a retrospective case series. Clinical records from 2011 to 2019 from a tertiary referral hospital in Boston, MA, USA were screened for cases, and case data were re-evaluated and analyzed. The total patient pool contained 65,385 individual cats, of which 797 were referred to the dermatology service. Medical records and biopsy specimens were reviewed; the information collected included signalment, clinical signs, physical examination and diagnostic tests, comorbidities and histopathologic findings. PCR was performed on biopsy specimens to test for papillomavirus DNA. Results The cystadenomatosis population consisted of 57 cases (7.1% of total cases referred to the dermatology service) with 105 affected ears. Twenty-seven cases (48 ears) were confirmed via histopathology; four cats (7%) exhibited clinically cystic lesions on the periocular, periorbital and perianal regions; only one cat did not have pinnal lesions. Domestic shorthair cats were most often affected. Relative risk for cystadenomatosis was 2.24 times higher in male cats. In 48 cats (84.2%), ears were bilaterally affected. Seven cats (12.3%) had malignant neoplasia, which included: inflamed adenocarcinoma (n = 5); mast cell tumor (n = 1); or squamous cell carcinoma (n = 1). PCR testing on biopsy specimens from 24 cats revealed feline papillomavirus type 2 DNA in only four cats. Conclusions and relevance Cystadenomatosis was more prevalent in senior non-purebred cats, over-represented in male cats and did not appear to be associated with papillomavirus, feline infectious peritonitis, feline immunodeficiency virus/feline leukemia virus status or other identifiable illnesses. Further studies are needed to investigate the causes of cystadenomatosis.
