Plain-English summary
An 8-year-old neutered male shih tzu developed multiple cystic nodules on his belly about ten days after surgery to remove bladder stones. While the surgical incision healed well, these new bumps were found along the suture line and surrounding skin. The vet diagnosed them as comedones (clogged hair follicles) and epidermal cysts (small, fluid-filled lumps). It seems that the surgery may have caused these cysts to form, especially since the dog had a condition that affects the skin. Treatment options may include monitoring the cysts or surgical removal if they become problematic.

Abstract
An 8-year-old neutered male shih tzu dog underwent laparotomy for cystolithectomy. Ten days later, multiple various-sized cystic nodules were observed on the suture line and surrounding abdominal skin, although the surgical incision had healed well. Microscopically, various-sized cysts lined with thin walls of stratified squamous epithelium in the dermis were dilated and filled with keratin. Adnexal differentiation from the wall was not seen. Thus, the abdominal lesions were diagnosed as comedones and epidermal cysts. Herein, we describe the case of a dog with comedones and epidermal cysts on the abdominal skin after a laparotomy. Key clinical message: Multiple various-sized cystic lesions of the follicles are described. The implantation of epidermal fragments into the dermis by surgery may induce epidermal cysts and comedones in the skin of hyperadrenocorticism-affected dogs.
