They are most commonly found on the head, neck, ears, and limbs, and are usually less than 2.5 cm in diameter. [8] Ulceration of the mass is common. Diagnosis is made through cytology of the mass. Cytology reveals cells with clear to lightly basophilic cytoplasm and round or indented nuclei with fine chromatin and indistinct nucleoli. [9]
The lesions occur as multiple cutaneous and subcutaneous nodules up to 4 cm diameter. They may disappear spontaneously, or regress and appear at new sites simultaneously. Topographically lesions may be found on the face, ears, nose, neck, trunk, extremities (including foot pads), perineum and scrotum. [1] [2] Treatment options in SH and CH.

The pocket is situated in the approximate location of the antitragus in the human ear. It occurs in a number of mammalian species, including weasels and bats, but is particularly noticeable on the domestic cat, as well as some dog breeds. The pocket is of unknown function, [2] and it is unclear if it has any at all. [1]
