What type of neoplasm is characterized by inappropriate gland formation?

• A. Sarcoma
• B. Adenocarcinoma
• C. Carcinoma in situ
• D. Fibromatosis

Answer: (B)

Adenocarcinoma is a type of neoplasm that arises from glandular epithelial tissue and is characterized by the formation of inappropriate or abnormal glandular structures. This aberrant gland formation occurs due to the transformation of normal glandular cells into malignant cells, which disrupts the normal architecture and function of the tissue. In adenocarcinomas, these neoplastic glands can be poorly formed or exhibit irregular sizing and shapes, which is a hallmark of malignancy. The presence of inappropriate gland formation is significant in the diagnosis and classification of adenocarcinomas, as it indicates a departure from normal tissue behavior and can provide insight into the aggressiveness of the tumor. Understanding the histological characteristics, such as glandular architecture and cellular atypia, is critical for pathologists when distinguishing adenocarcinomas from other types of neoplasms.
