• Adenolipomatosis — A condition characterized by the benign, simultaneous, and excessive proliferation of adipose tissue within or around lymph nodes and glandular structures, leading to a diffuse enlargement of their volume. This histopathological structural phenomenon disrupts the normal architecture of regional soft tissue, generating palpable nodular formations that are often asymptomatic but can pose differential diagnosis challenges with simple lipomas or malignant lymphadenopathies.
• Adipofibroma — A benign tumor formation with a mixed histological structure, composed of a mixture of mature adipose tissue and proliferated fibrous connective tissue. This structural benign neoplasm occurs most frequently within the subcutaneous cellular tissue, internal organs, or the mediastinum, presenting a firm-elastic consistency and sharp demarcation from neighboring anatomical structures.
• Lipoma — A benign, well-circumscribed, and encapsulated tumor formation consisting of the localized proliferation of mature adipose cells; a very rare medical term used as a perfect synonym for the classic lipoma. This structural benign neoplasm develops within the subcutaneous cellular tissue or intermuscular spaces, presenting a soft, elastic consistency and a slow evolution, without tendencies for infiltration or malignancy.
• Adiposis — A pathological condition marked by the excessive, massive, and diffuse accumulation of fat within the subcutaneous connective tissue or around internal organs; this altered structural state (clinically known also as lipomatosis or severe obesity) can be caused by metabolic disorders, endocrine imbalances, or genetic factors, affecting normal mobility and cardiovascular functions.
• Angiolipoma — A benign tumorous formation of a mixed nature, structurally composed of mature adipose tissue (lipoma) and a well-defined, rich network of proliferated and often thrombosed blood vessels (angiomatous component). This histological lesion frequently occurs at the subcutaneous level, particularly on the forearms or trunk in young adults, clinically manifesting as firm, well-circumscribed nodules that, unlike classic lipomas, are often painful to the touch.
