- Adenocancroid — A rare malignant tumor formation with a mixed structure, characterized by the simultaneous presence of adenocarcinoma (glandular) and epidermoid carcinoma (squamous) elements. This structural neoplastic form exhibits high biological aggressiveness and a rapid capacity for metastasis, requiring a complex therapeutic protocol based on surgery, chemotherapy, and radiotherapy.
- Adenocarcinoma — A form of malignant tumor (cancer) originating in glandular epithelial cells or in structures exhibiting secretory characteristics. This type of neoplasm can structurally develop in various internal organs, such as the stomach, colon, lungs, breast, or prostate, possessing a high capacity for local invasion and metastasis through the lymphatic or blood system.
- Adenosarcoma — An extremely rare mixed malignant tumor, characterized by the concurrent presence of a benign glandular epithelial component and a malignant mesenchymal (sarcomatous) stroma. This complex structural entity occurs most frequently within the female genital tract (especially in the uterine endometrium), requiring a rigorous histopathological diagnosis and an aggressive surgical therapeutic approach.
- Angiosarcoma — A highly aggressive and rare malignant tumorous formation, developed through the chaotic and atypical proliferation of endothelial cells lining the interior of blood vessels or lymphatic vessels. This well-defined structural oncological lesion can appear in any region of the body, but frequently affects the skin (especially the scalp), subcutaneous tissue, breast, liver, or spleen, being characterized by rapid progression, deep local infiltration, and a high rate of early metastasis.
