title: Primary intratracheal lymphosarcoma in four cats.
abstract: Four cats presented with clinical signs suggestive of respiratory disease, including dyspnea, wheezing, cyanosis, inspiratory stridor, coughing, and gagging. Radiographs revealed intratracheal masses. Bronchoscopy allowed for lesion localization and collection of samples for cytopathological and histopathological evaluation, which confirmed a diagnosis of lymphosarcoma. Cats treated with systemic chemotherapy or radiation were able to achieve complete remission and long-term resolution of clinical signs.
