False gigantism is a hereditary disease associated with excess fat deposition in the subcutaneous tissue, which has nothing to do with a true tumor, and appears against the background of certain diseases or nutritional imbalances. False gigantism is practically no different in appearance from true gigantism. Also, gigantism should not be confused with obesity or with metabolic diseases such as diabetes and hypothyroidism, in which the structure of the skin also suffers to some extent, such as in patients with diabetes.
True gigantism is a slowly developing malignant neoplasm characterized by abnormal proliferation of the connective tissue base of the dermis, which leads to excessive migration between the skin and the anatomical structure that it covers. Gigantomlo is commonly referred to as a tumor on the face, but can also develop anywhere on the body.
Possible clinical variants of giants. A giant can be (1) monomorphic, (2) multiform, or (3) mixed. Monormorphic tumors are those that have a typical appearance. These include angioma, nevus or fibroplastic giant. Multimorphic - appear in the form of several tumors of the same type or change in a progressive manner over time, an example of such a tumor is the melanocytic giant. But mixed tumors are giants, characterized by a combination of various forms of various neoplasms. The best known examples are synmodigitroma, mixed and keratoacanthoma.
