Vacuoles are more prominent in mucinous tumors but can be seen in serous tumors as well. Adenocarcinoma [ 1 ] ( / ˌ æ d ɪ n oʊ k ɑːr s ɪ ˈ n oʊ m ə / ; plural adenocarcinomas or adenocarcinomata / ˌ æ d ɪ n oʊ k ɑːr s ɪ ˈ n oʊ m ə t ə / ; AC ) is a type of cancerous tumor that can occur in several parts of the body.
Adenoma is a benign tumor of glandular tissue, such as the mucosa of stomach, small intestine, and colon, in which tumor cells form glands or gland-like structures. In hollow organs (digestive tract), the adenoma grows into the lumen - adenomatous polyp or polypoid adenoma.
The colorectal adenoma is a benign glandular tumor of the colon and the rectum. It is a precursor lesion of the colorectal adenocarcinoma ( colon cancer ). [ 1 ] [ 2 ] [ 3 ] They often manifest as colorectal polyps .
Tumor budding is a well-established independent marker of a potentially poor outcome in colorectal carcinoma that may allow for dividing people into risk categories more meaningful than those defined by TNM staging, and also potentially guide treatment decisions, especially in T1 and T3 N0 (Stage II, Dukes’ B) colorectal carcinoma.
Further treatment is managed similarly to other types of cervical cancer, such as performing an excision procedure in the form of a cold knife conization or a loop electrosurgical excision procedure (LEEP). Further surgical management depends upon the depth of tumor invasion. Invasive tumors may require chemotherapy and radiation treatment.
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.
Treatment options depend on the type of tumor and on its size: Prolactinomas (microadenomas and macroadenomas) are most often treated with cabergoline or bromocriptine (both dopamine agonists) as the first line of treatment. [68] Medical treatment usually effectively decreases tumor size as well as alleviates symptoms. [68]

Specialty: General surgery, gastroenterology: Symptoms: Usually asymptomatic: Usual onset: 50–60 years of age: Risk factors: Female gender: Treatment: Surgical resection (if symptomatic) Deaths: 0.1% [1]
