A ceruminous adenoma is a benign glandular neoplasm which arises from the ceruminous glands located within the external auditory canal. These glands are found within the outer one third to one half of the external auditory canal, more common along the posterior surface; therefore, the tumor develops within a very specific location.
Benign tumors take several years to develop and are more difficult to detect due to their freely movable nature. [6] The only indicator of benign tumors is self-trauma of a form called lick granuloma or "boredom sores", [7] which can be caused by excessive licking by the cat. [6] This is a sign that the cat is suffering from anxiety. [8] [9]
Ceruminous adenocarcinoma is a malignant neoplasm derived from ceruminous glands of the external auditory canal.This tumor is rare, with several names used in the past. [3] [4] Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), [1] [2] and ceruminous mucoepidermoid carcinoma.
Neuroendocrine adenoma middle ear (NAME) is a tumor which arises from a specific anatomic site, the middle ear. [1] NAME is a benign glandular neoplasm of middle ear showing histologic and immunohistochemical neuroendocrine and mucin-secreting differentiation (biphasic or dual differentiation).
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
The symptoms depend on the tumor's location and degree of invasion. For example, tumors in the gastrointestinal tract may cause vomiting, diarrhea, or weight loss. Tumors in the mouth may cause bad breath, difficulty swallowing, or lack of appetite. Tumors arising in the peripheral nerves may cause pain, lameness, or neurological symptoms.
A benign tumor is a mass of cells that does not invade neighboring tissue or metastasize (spread throughout the body). Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate. Benign tumors have relatively well differentiated cells.
Much like the speculation that cats love cream (adult cats are most often lactose intolerant), there are many questions surrounding dogs' ability to digest dairy products. Luckily, we are here to ...
