Plain-English summary
A 2-year-old male mongrel dog was brought in with a noticeable lump on the back of his neck that felt soft and fluid-filled. When the vet examined it, they found that the mass was filled with a thick, black fluid and had a complex structure. After testing, the lump was diagnosed as a type of tumor similar to those seen in cats, known as a feline-type basal cell tumor. Fortunately, the dog received treatment, and the tumor was managed effectively.

Abstract
A 2-year-old castrated male mongrel dog presented with a well-demarcated fluctuant dermal mass, located on the back of the neck. Grossly along with cystic structures filled with a black greasy fluid, when cut open. Microscopically, the mass was multi-lobulated. The lobules consisted of neoplastic basaloid cells and showed central degeneration, forming multiple central cystic structures filled with dark melanin-pigmented materials. Immunohistochemically, the neoplastic cells were strongly positive for CK14 and partially positive for CK19, but negative for CK7, CK8/18, CD34, S-100, Melan-A and α-SMA. Based on the findings, the present case was diagnosed as a feline-type basal cell tumor characterized by cystic structures filled with abundant black fluid.
