Desmoid tumor

Desmoid tumors are the most common among diffuse connective tissue neoplasms; characterized by infiltrative growth with minimal damage to surrounding tissues.

Histologically, there are two types of desmoid – benign and malignant. Over the past ten years, malignant desmoid tumors have for the first time begun to predominate over benign ones. Differences can also be identified through cytological and molecular genetic typing of tumors.

**Pathological anatomy and histology** Hyperplasia of the lamina propria of the mucous membrane of the abdominal cavity, reproductive tract, pelvis, and pericardium is known as lipoma, glandular hyperplasia and mesenchymal hypertrophy of the organ wall, i.e. There are fatty, glandular and fibrous types of tumor. What all these formations have in common is predominantly extramucosal localization of growth. * Dermoid tumors include the epidermis, hair, bones and teeth. A characteristic feature of dermoids is the possibility of transformation into more serious invasive heterotypic tumors - from epithelial or mesenchymal elements. Atypical dermatofibrosarcomas are very rare, but cannot be distinguished from benign fibrous tumors

Desmoid tumor is a rare disease that appears as a tumor arising from the connective tissue located near the muscles and joints. Typically, the tumor is diagnosed in people aged 40 to 60 years. The tumor develops unnoticed and slowly, and may not be as pronounced. Gradually, the desmoid tumor begins to impede muscle movement, worsening the person’s quality of life.

In addition, this disease can lead to the formation of fibrosis in the abdominal cavity and diaphragm.
