A 9-year-old male Yorkshire terrior with recurrent chronic otitis externa and otitis interna was referred to the Veterinary Medical Teaching Hospital of Seoul National University. Radiographic findings indicated mineralization around the right ear canal. A tan nodular mats, 1 cm in diameter. was noted near the tympanum after total ear canal ablation. Cytologically. the imprint smear of the cut surface of the mass produced clusters of cells with abundant and weakly basophilic cytoplasm, one small round nucleus and one or two nucleoli, mixed with both degenerate and non degenerate neutrophils. The location of the nuclei was eccentric, and some cells contained somewhat coarse black granules in their cytoplasms, on which the mass was diagnoted as ceruminous gland adenoma or hyperplasia associated with inflammation. Histopathologic examination of the tumor was compatible with a diagnosit of ceruminous gland adenoma. The patient is responding well to sugery and antimicrobial treatment.

Gross and light microscopic findings are described for 34 canine sweat gland neoplasms including tumors derived from apocrine gland in anal sac and ceruminous gland in ear. Affected dogs are usually 5.2 years and sex predilection have not been seen. Sweat gland carcinoma(n=19) is predominant type for sweat gland neoplsm, while papillary syringadenoma(n=2) and spiradenoma(n=2) are rare type in this study. Distinct patterns identified in cutaneous sweat gland carcinoma are tubular(n=7), solid(n=5), mixed(n=4), papillary(n=2) and signet-ring(n=1). Mixed tumors which are characterized by myxomatous and chondroid metaplasia are seen in cutaneous sweat and ceruminous gland. The carcinoma derived apocrine gland of the anal sac induces humoral hypercalcemia of malignancy in two dogs in this study. Histologically, apocrine gland carcinoma of the anal sac has distinct rossette formation.

A 12-year-old, female, Maltese dog was presented with otic signs, such as pruritus and malordorous discharge. Medical treatment of otitis externa had been carried out for several months at primary animal hospital. Radiography, ultrasonography (US), computed tomography (CT), fine needle aspiration (FNA), and histopathological examination were performed for the diagnosis of ceruminous gland adenocarcinoma. Total ear canal ablation and lateral bulla osteotomy were performed for excision of the tumor. Facial nerve paralysis developed after surgery is getting better through the acupuncture therapy.
