Abstract

Ceruminous gland cystomatosis is an uncommon non-neoplastic disorder arising from the meatus ceruminous gland. An 11-month-old male Himalayan cat was referred for evaluation of nodular eruptions on the concave pinna of both the ears that was not responding to antibiotics and anti-inflammatory agents. The condition was tentatively diagnosed as ceruminous gland cystamatosis based on the history and clinical signs, which was later confirmed by histopathological evaluation. The nodules were cauterized using electro-surgery unit under tramadol-xylazine-ketamine-diazepam anesthesia followed by medication using topical and systemic antibiotics and anti-inflammatory agents. The cat had an uneventful recovery except for mild scar formation at the cauterized site.
