Epithelioid Sarcoma: Everything About A Rare, Slow-Growing Soft Tissue Cancer

Epithelioid Sarcoma is a soft tissue cancer that is rare in nature. It grows slowly in the host and patients who suffer from Epithelioid usually find growing tissue under their skin of a finger, hand, forearm, lower leg or foot. Moreover, it can grow in any area of the body. Epithelioid sarcoma has a high rate of recurrence and metastasis.

The disease has behavior to create recurrences and metastasis, therefore, affecting the regional lymph nodes, lung, bone, brain, and other locations, including the scalp. Epithelioid sarcoma typically begins with tiny growth of tissue. Painless firm development or lump.

It typically begins as a single development. Often, this sarcoma looks like ulcers that do not heal and appear to be an open wound in the body. So if you got such symptoms then you should rush to the hospital as soon as possible. What is the treatment of Epithelioid Sarcoma? Know about the Diagnosis in the following section.

Rare and Slow Growing Tissue Cancer Epithelioid Sarcoma

Epithelium sarcoma is a rare mesenchymal tissue soft tissue sarcoma, with epithelium characteristics. Research F.M. Enzinger’s clearly characterized Epithelium cancer in 1970. Moreover, A proximal version is noted where it occurs in the upper extremities. Also, some rare case has appeared where doctor noticed slow-growing of soft tissue in the pelvis, vulva, penis, and spine.

Histologically, epithelioid sarcoma forms nodules surrounded by bland, polygonal cells with eosinophilic cytoplasm, and peripheral spindling with central necrosis. In addition, Typically, epithelioid sarcomas release vimentin, cytokeratin, epithelial membrane antigen, and CD34, whereas they are generally negative for S100, desmin, and FLI-1. But usually positive stain for CA125.

In general, after initial treatment, epithelioid sarcoma has a high rate of relapse and continues to recur locally (at or near the original site of the tumor). The epithelioid sarcoma also shows lymphatic spread (in 22-48% of cases), and metastasis (in 21-63% of cases).

Epithelioid Sarcoma Symptoms And Diagnosis

Epithelioid sarcoma is a tumor that develops gradually and is relatively painless and often results in a long period of time between presentation and diagnosis. Besides, It is often misdiagnosed because of its ambiguity, mistaken as a persistent wart or cyst. It most often appears as a small, soft mass or a series of bumps in the distal limbs (fingers, hands, forearms, or feet).

Tissue biopsy is the preferred diagnostic method. A sentinel lymph node biopsy is often performed because of a high incidence of lymph node involvement. It may be difficult to diagnose epithelioid sarcoma, because it may be mistaken with other diseases with similar signs. An ulcer that is not healing on the skin, for example, could be mistaken for a skin infection.

The major test and procedures for Epithelioid Sarcoma include Imaging and Biopsy. There are also emerging medical approaches for the diagnosis, such as New Chemotherapies, Immunotherapies, Anti-angiogenic Therapies, and Targeted Therapies.


Given the level of information it offers, magnetic resonance imaging (MRI) is usually the imaging process. In addition, Other imaging techniques may sometimes be used, such as computed tomography (CT) or positron emission tomography (PET).


For examination in a laboratory, the doctor conducts a biopsy using a long, thin needle to take a sample of the suspected sarcoma or a larger lump. Besides, During surgery, a biopsy sample is occasionally removed. A pathologist analyzes the sample to determine if it is cancer and if so, doctor test the type and the aggressive nature of it.


There are several types of treatment available in the hospital. Nonetheless, the most effective procedure for epithelioid sarcoma is surgery. Here are some of the treatments that the patient usually follows.

Epithelioid Sarcoma Surgery

Surgery generally involves eradicating the soft growing tissue from the body part. Extracting cancerous cell and a buffer of underlying healthy tissue to help prevent a recurrence. In serious cases, there is a small risk that affected body part, Limb would need to be amputated. Well, surgeons try their best depending on the size, extent, and position of cancer.



Chemotherapy, Epithelioid Sarcoma: Everything About A Rare, Slow-Growing Soft Tissue Cancer

Chemotherapy is a strong treatment, a drug that is used to kill the cancer cells. It uses drugs to kill cancer cells. Chemotherapy seems to be less effective in the treatment of epithelioid sarcoma. Although it is sometimes used in addition to surgery or when cancer has spread.

Radiation therapy

Radio therapy

This Radiation therapy uses high energy beams to kill cancer cells, such as X-rays or protons. Sometimes, Radiation therapy shrinks the tumor and also reduces the risk of the cancer cell.  It helps to reduce the risk of recurrence after surgery.

Clinical trials

Clinical trials are New Treatment Research. This research provides an opportunity to try the new treatment options but it may not be clear about the risk of side effects.

Moreover, Clinical trials are tests or clinical-research studies. In addition, the aim of these prospective human biomedical research studies is to address specific scientific issues, including new treatments such as new vaccines, medications, dietary choices, etc.
