Feline minor salivary gland adenocarcinoma: retrospective case series and literature review.

CASE SERIES SUMMARY: Salivary gland adenocarcinoma, of major or minor salivary gland origin, is an uncommon tumor in cats. This article describes the clinical features, morbidity and survival rates of four cats with salivary gland adenocarcinoma arising from minor salivary gland tissue. Medical records from a private multicenter dentistry and oral surgery practice were reviewed for the period between 2007 and 2021. Four cats were included in this retrospective case series study, with oral masses on either the right or left caudal mandibular labial buccal mucosa. The inclusion criteria included a diagnosis of salivary gland adenocarcinoma in an anatomical location with lack of involvement of a major salivary gland, complete medical history and a follow-up of at least 6 months. The age range of the cats was 9-15 years; three of the cats were castrated males and one was a spayed female. Curative intent surgery was performed in three cats, whereas palliative surgery (debulking) owing to extensive soft tissue invasion was performed in one cat. Survival times were in the range of 210-1730 (mean 787) days. All four cats were euthanized owing to local recurrence and decreased quality of life, regardless of treatment modality. RELEVANCE AND NOVEL INFORMATION: There are limited documented studies reporting the prevalence of salivary gland neoplasia affecting minor disseminated glands in the oral cavity of feline patients. Salivary gland adenocarcinoma should be a differential in cats presenting with caudal labial masses. Surgical resection has been the recommended treatment for salivary gland neoplasia of major salivary gland origin. According to this current case series, we propose that early aggressive surgical treatment with wide surgical margins should be performed for cats with salivary gland adenocarcinoma of minor salivary gland origin. Surgery increased the quality and duration of life; however, each patient was euthanized owing to local recurrence and morbidity.

Intestinal Obstruction by Giant Meckel's Diverticulum.

BACKGROUND: Meckel's diverticulum is the most common congenital anomaly of the small bowel and is caused by the incomplete obliteration of the omphalomesenteric duct during the eighth week of gestation. METHODS: We report the case of a 51-year-old male who presented to the emergency department with epigastric pain, vomiting, and abdominal distension. Clinically, he had a high intestinal obstruction without any mechanical cause on computed tomography scan. A median laparotomy was proposed. RESULTS: An internal ileum hernia was identified twisted around a giant Meckel's diverticulum with a mesodiverticular artery, coursing from the base of the mesentery to the diverticulum. A small bowel segmental resection was performed, containing the diverticulum. Histology revealed a 15-cm long Meckel's diverticulum with no heterotopic mucosa. CONCLUSION: Small bowel obstruction due to an internal ileum hernia twisted around a giant Meckel's diverticulum with a mesodiverticular artery is very rare, and its diagnosis is challenging, requires a high level of suspicion, and it is only performed by exploratory surgery.

CONTEXTO: O divertículo de Meckel é a malformação congénita mais frequente do intestino delgado e deve-se ao encerramento incompleto do canal onfalomesentérico cerca da 8ª semana de gestação. MÉTODOS: Apresentamos o caso de um doente de 51 anos de idade que recorre ao serviço de urgência por dor epigástrica, vómitos e distensão abdominal. Apresentava um quadro clínico de oclusão intestinal alta sem evidência na tomografia computorizada de causa mecânica para a oclusão. Foi proposta laparotomia exploradora. RESULTADOS: Identificou-se uma hérnia interna de intestino delgado em torno de um divertículo de Meckel gigante cuja ponta estava aderente ao mesentério devido a persistência de uma artéria divertículo-mesentérica. Realizámos resseção segmentar de intestino delgado, contendo o divertículo. A anatomia patológica foi compatível com divertículo de Meckel com 15 cm sem presença de mucosa heterotópica. DISCUSSÃO: A oclusão intestinal de Intestino Delgado devido a hérnia interna em torno de um divertículo de Meckel gigante com persistência da artéria diverticulo-mesentérica é muito raro e o seu diagnóstico é dificil, requer alto nível de suspeição e só é feito após cirurgia exploradora.

Trichobezoar - A Rare Cause of Abdominal Mass and Gastric Outlet Obstruction.

The authors present the clinical case of a 14-year old girl with weight loss, anorexia, epigastric abdominal pain and postprandial vomiting with 5 months duration. There was a background of trichophagia for 2 years without evidence of alopecia or psychiatric history. The physical examination revealed an epigastric mass motionless, stony, with poorly defined limits, painful on palpation and about 7 cm diameter. Abdominal ultrasonography showed thickening of the gastric wall and antrum with gastric distension. The abdominal tomography scan and endoscopic examination revealed the presence of a bulky trichobezoar occupying almost the entire gastric lumen. It was decided to undergo gastrotomy and extraction of the bezoar. The postoperative period was uneventful.

Apresentamos o caso clínico de uma adolescente de 14 anos com emagrecimento, anorexia, epigastralgia e vómitos pós-prandiais com 5 meses de evolução. Apurou-se história de tricofagia com 2 anos de evolução mas sem áreas de alopécia ou antecedentes psiquiátricos. Apresentava massa epigástrica imóvel, pétrea, de limites mal definidos, dolorosa à palpação e com cerca de 7 cm de diâmetro. A ecografia abdominal mostrou espessamento da parede gástrica e do antro com distensão gástrica. Realizou tomografia abdominal e endoscopia digestiva alta que revelaram a presença de volumoso tricobezoar ocupando quase a totalidade do lúmen gástrico. Foi decidido realizar gastrotomia e extração do bezoar. O pós-operatório decorreu sem incidentes.
