Plain-English summary
A 14-month-old male German Shepherd was brought to the vet because of a firm, chalky white mass measuring about 6 x 3 cm on his left back leg. After taking a sample from the mass, the vet found it was a condition called calcinosis circumscripta, which is a type of abnormal calcium buildup. The mass was surgically removed, and the diagnosis was confirmed through further testing. The dog recovered well after the surgery and is now doing fine.

Abstract
A 14-month-old, intact, male German Shepherd dog was referred for a 6 x 3-cm, firm mass in the left pelvic limb. Fine needle aspiration yielded chalky white material. May-Grünwald-Giemsa-stained smears showed a uniform background of amorphous, poorly stained, light-blue material and scattered foamy macrophages, a few naked nuclei, and cellular debris. The cytologic diagnosis of calcinosis circumscripta was confirmed by histologic evaluation of the surgically removed mass. In this report, we document the unique cytologic and histologic patterns of this uncommon tumor-like lesion.
