Introduction
The aim of this paper is to conduct a retrospective study, in order to register and analyse clinical cases of adenomas and adenocarcinomas of perianal glands, which have been extracted surgically and have been confirmed with histopathological examination, and record their progress after a long lasting post surgery follow up.
Clinical cases
The 50 clinical cases that were chosen were patients from the Clinic, from the year 2000 until the year 2023, that were diagnosed with adenoma or adenocarcinoma of perianal glands with histopathological or cytological examination and had undergone a surgical procedure.
Results
Among these 51 cases, with an average weight of 12.2 kg, in adenomas and 11.75 kg in adenocarcinomas, an average age of 11 years in adenomas and 11.25 years in adenocarcinomas, there were 16 male neutered, 7 adenomas and 9 adenocarcinomas, 28 male non-neutered, 15 adenomas and 13 adenocarcinomas, 5 female neutered, 3 adenocarcinomas and 2 adenomas and 2 female non-neutered adenomas. Therefore, 26 were diagnosed with adenomas and 25 with adenocarcinomas. 17 cases involved adenomas with orchiectomy, while 13 cases involved adenocarcinomas with orchiectomy. Metastasis and chemotherapy were observed in 2 cases. Following a median follow-up of 8 years, 94.11% of adenoma cases and 66.66% of adenocarcinoma cases survived.
Conclusions
Perianal gland adenomas exhibit favorable outcomes post-surgical treatment and orchiectomy. However, perianal gland adenocarcinomas generally have an unfavorable prognosis.
