Dabska-type hemangioendothelioma is a rare type of vascular tumor that occurs in the skin and soft tissues of the body. It is also known as Dabska tumor or Dabska-type angiosarcoma. This type of tumor was first described by Maria Dabska in 1969 and was later recognized as a distinct entity in 1993.

Dabska-type hemangioendothelioma is more common in children and young adults, but it can occur at any age. It usually presents as a painless, slow-growing nodule or lump on the skin or subcutaneous tissues. The tumor may be reddish or bluish in color, and it may be accompanied by bruising or bleeding.

Dabska-type hemangioendothelioma (DHE) is a rare vascular tumor that typically affects children and young adults. It was first described by the Polish pathologist Maria Dabska in 1969. DHE is also known as Dabska tumor or papillary intralymphatic hemangioendothelioma.

DHE is characterized by the proliferation of abnormal blood vessels (angiogenesis) within lymphatic vessels. This results in the formation of papillary or polypoid structures that protrude into the lymphatic channels. The tumor cells are composed of endothelial cells, which are the cells that line blood vessels.

Types

There are several types of DHE, based on the location and the size of the tumor. These include:

Cutaneous DHE: This type of DHE is found on the skin or in the subcutaneous tissue (the tissue beneath the skin). Cutaneous DHE usually presents as a small, red or purple papule (a small, raised bump) or nodule (a solid, round lesion) that may be painful or tender to the touch.
Subcutaneous DHE: This type of DHE is found in the deeper layers of the skin, in the subcutaneous tissue. Subcutaneous DHE may present as a mass or a nodule that may be painful or tender to the touch.
Soft tissue DHE: This type of DHE is found in the soft tissues, such as the muscles or tendons. Soft tissue DHE may present as a mass or a nodule that may be painful or tender to the touch.
Bone DHE: This type of DHE is found in the bone. Bone DHE may cause bone pain, swelling, and tenderness.
Pulmonary DHE: This type of DHE is found in the lungs. Pulmonary DHE may cause coughing, shortness of breath, chest pain, and hemoptysis (coughing up blood).
Hepatic DHE: This type of DHE is found in the liver. Hepatic DHE may cause abdominal pain, jaundice (yellowing of the skin and eyes), and hepatomegaly (enlargement of the liver).
Other rare locations: DHE can also occur in other rare locations such as the breast, pancreas, spleen, lymph nodes, and central nervous system.

Causes

The exact cause of DTH is still not fully understood, but researchers have identified several potential factors that may contribute to the development of this tumor and possible causes of DTH.

Genetic mutations: Some cases of DTH have been linked to genetic mutations that affect the growth and division of cells. These mutations can be inherited or acquired.
Chromosomal abnormalities: Chromosomal abnormalities, such as translocations or deletions, have also been associated with DTH in some cases.
Exposure to radiation: Exposure to ionizing radiation, such as radiation therapy, may increase the risk of developing DTH.
Exposure to chemicals: Exposure to certain chemicals, such as vinyl chloride, may increase the risk of developing DTH.
Viral infections: Some studies have suggested that viral infections, such as human herpesvirus 8 (HHV-8) or human papillomavirus (HPV), maybe a risk factor for DTH.
Immune system disorders: Individuals with immune system disorders, such as HIV/AIDS or autoimmune diseases, may be at a higher risk of developing DTH.
Hormonal imbalances: Hormonal imbalances, such as those seen in pregnancy or puberty, may contribute to the development of DTH.
Trauma: Trauma to the affected area, such as a blow or injury, may trigger the development of DTH.
Chronic inflammation: Chronic inflammation in the affected area may increase the risk of DTH.
Lymphatic abnormalities: Abnormalities in the lymphatic system, such as lymphatic malformations, may be a risk factor for DTH.
Hemangiomas: Individuals with pre-existing hemangiomas may be at a higher risk of developing DTH.
Liver disease: Liver disease, such as cirrhosis, may increase the risk of developing DTH.
Blood disorders: Blood disorders, such as clotting disorders or anemia, may be a risk factor for DTH.
Obesity: Obesity may be a risk factor for DTH, although more research is needed in this area.
Age: DTH is more common in children and young adults, although it can occur at any age.
Gender: DTH is slightly more common in females than males.
Race: DTH is more common in individuals of Asian descent.
Family history: In some cases, DTH may run in families.
Immunosuppressive therapy: Immunosuppressive therapy, such as after an organ transplant, may increase the risk of developing DTH.
Unknown factors: In some cases, the exact cause of DTH may be unknown.

Dabska-type hemangioendothelioma is a rare tumor that can occur in different parts of the body. While the exact cause of DTH is still not fully understood, several potential factors have been identified, including genetic mutations, exposure to radiation or chemicals, viral infections, immune system disorders, hormonal imbalances, trauma, chronic inflammation, lymphatic abnormalities, hemangiomas, liver disease, blood disorders, obesity, age, gender, race, family history, immunosuppressive therapy, and unknown factors. If you suspect that you or someone you know may have DTH, it is important to seek medical attention as soon as possible for an accurate diagnosis and appropriate treatment.
