- Acanthoma — A benign cutaneous tumor formation characterized by the hyperplastic proliferation of keratinocytes within the stratum spinosum of the epidermis (acanthosis). This well-circumscribed lesion can manifest in various clinical and histological forms, the most notable being clear cell acanthoma (Degos) and acanthoma fissuratum, requiring microscopic differential diagnosis to exclude epidermal malignancies.
- 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.
- Aleukemia — A particular clinical form of leukemia characterized by the malignant proliferation of hematopoietic tissues, but in which the total number of leukocytes in the peripheral blood remains normal or even decreased, with tumor cells (blasts) being absent or extremely rare in the general circulation, although heavily present in the bone marrow.
- Anaplasia — A pathological cellular condition characterized by the complete loss of structural and functional differentiation of cells within a tissue, causing them to revert to a primitive, embryonic-like form. This phenomenon represents a major indicator of tumor malignancy, being associated with an accelerated rate of cell division, severe nuclear atypia, and a profound alteration of the normal architecture of the affected organ.
- Pathologist — A female physician specialized in pathological anatomy, the medical discipline concerned with the study of macroscopic and microscopic changes induced by diseases in cells, tissues, and organs. She analyzes biopsies, surgically excised specimens, and cytological products to establish definitive diagnoses of tumors and inflammatory conditions, playing a crucial role in guiding oncological treatment.
- Pathologist — A physician specialized in pathological anatomy responsible for diagnosing diseases based on the macroscopic examination of organs and the microscopic evaluation of tissues or cells obtained through biopsy or surgery. This specialist plays a decisive role in cancer staging, identifying autoimmune diseases, and performing clinical autopsies to determine causes of death.

- Anatomopathological — Pertaining to or belonging to pathological anatomy; related to the study of lesions and structural changes, either macroscopic or microscopic, caused in the organism by a specific disease. This term describes laboratory investigations, diagnostic techniques, or characteristics of pathologically altered tissues, essential for definitive medical confirmation.
- Pathology — A fundamental branch of medicine that deals with the study of macroscopic, microscopic, and molecular changes caused by diseases in the cells, tissues, and organs of the human body. This discipline plays a decisive role in the definitive diagnosis of tumors and inflammatory diseases through the interpretation of biopsies, surgical specimens, and cytological examinations.
