Where does malignant melanoma usually metastasize?

Melanomas are capable of metastasizing to both regional and distant sites. The most common sites of regional metastasis are nearby skin, sub-cutaneous tissue, and lymph nodes [48].

Can melanoma spread to the gallbladder?

Metastatic melanoma is an aggressive disease that can spread to many organs of the body. In rare cases, it can spread to the gallbladder causing secondary lesions, yet presenting with little to no symptoms. Therefore, most cases of metastatic melanoma lesions to the gallbladder go undiagnosed.

What is metastatic gallbladder adenocarcinoma?

Metastasis is the spread of cancer from the primary site (place where it started) to other places in the body. Metastatic gallbladder cancer may spread to surrounding tissues, organs, throughout the abdominal cavity, or to distant parts of the body.

What are symptoms of metastatic melanoma?

Metastatic melanoma symptoms

Fatigue.
Swollen or painful lymph nodes.
Weight loss.
Loss of appetite.
Trouble breathing or a cough that doesn’t go away.
Bone pain.
Headaches.
Seizures.

Can melanoma spread to the stomach?

Melanoma is the most common cancer to metastasize to the gastrointestinal tract; however, metastasis to the stomach is a rare occurrence.

How do you know if melanoma has spread to the liver?

If melanoma spreads to the liver, specific symptoms may include: Loss of appetite. Fatigue or lethargy. Jaundice (yellowing of the skin or whites of eyes)

What is the 5-year survival rate for stage 4 melanoma?

The 5-year survival rate as of 2018 for distant metastatic (Stage IV) melanoma is 22.5%.

Can melanoma spread to liver?

Melanoma usually spreads through the body’s blood vessels to the liver. Liver metastases are sometimes present when the original (primary) cancer is diagnosed, or it may occur months or years after the primary tumor is removed. After the lymph nodes, the liver is the most common site of metastatic spread.

What causes gallbladder adenocarcinoma?

Gallbladder and bile duct It’s not clear what causes gallbladder cancer. Doctors know that gallbladder cancer forms when healthy gallbladder cells develop changes (mutations) in their DNA. A cell’s DNA contains the instructions that tell a cell what to do.

What does a mass on the gallbladder mean?

Lumps in the belly If the cancer blocks the bile ducts, the gallbladder can swell. Gallbladder cancer can also spread to nearby parts of the liver. These changes can sometimes be felt by the doctor as lumps on the right side of the belly. They can also be seen on imaging tests such as an ultrasound.

Is metastatic melanoma always fatal?

Survival for all stages of melanoma around 90 out of every 100 people (around 90%) will survive their melanoma for 5 years or more after diagnosis. more than 85 out of every 100 people (more than 85%) will survive their melanoma for 10 years or more after they are diagnosed.

Is Stage 4 melanoma always fatal?

Prognosis: Stage IV melanoma is very difficult to cure as it has already spread to other parts of the body. However, a small number of people respond well to treatment, achieve No Evidence of Disease (NED), and survive for many years following diagnosis.

How does melanoma affect the digestive system?

Symptoms of a Digestive System Melanoma may be nonspecific, including blood in the stool, stomach pain, vomiting, diarrhea, weight loss and anemia (low red blood cell count). The cause of Digestive System Melanoma is not well understood.

What is a gastric melanoma?

Primary gastric melanoma is an uncommon malignancy that manifests with symptoms such as abdominal pain, nausea, hematemesis, and melena, as well as nonspecific symptoms of fatigue, anemia, and weight loss. Accurate diagnosis depends on biopsy and IHC staining for melanoma markers such as SOX10, S100, and HMB-45.

How often does melanoma spread to the liver?

Background Metastases to the liver are diagnosed in 10% to 20% of patients with American Joint Committee on Cancer stage IV melanoma.

Is Stage 4 melanoma always terminal?

How fast does metastatic melanoma spread?

How fast does melanoma spread and grow to local lymph nodes and other organs? “Melanoma can grow extremely quickly and can become life-threatening in as little as six weeks,” noted Dr. Duncanson. “If left untreated, melanoma begins to spread, advancing its stage and worsening the prognosis.”

What is the’gold-standard’treatment for metastatic melanoma of the gallbladder?

The “gold-standard” treatment of metastatic melanoma of the gallbladder remains unclear. We report two cases of patients with past history of cutaneous melanoma who developed visceral metastases. The first patient was asymptomatic and had a widespread disease with metastatic involvement of both the spleen and the gallbladder.

What is the prevalence of melanoma of the gallbladder?

Introduction Melanomas of the gallbladder (GB) are extremely rare. They can be primary or secondary, both associated with very poor prognosis but cannot be differentiated histologically. Reports from autopsies show that the prevalence of secondary (metastatic) melanomas to the GB is between 15% and 20% [1,2].

Is laparoscopic cholecystectomy necessary for the removal of melanoma metastasis in gallbladder?

Following multidisciplinary team meeting, it was decided to perform a laparoscopic cholecystectomy to remove the gallbladder metastasis. New occurrence of a melanoma metastasis in the gallbladder is extremely rare, especially in stable disease. The therapeutical concept must be discussed extensively in the present of this metastasized tumor.

What can a CT scan of the gallbladder show?

The scan can reveal GB wall thickening, an intramural mass if greater than 1 cm without acoustic shadow and distinguish between stones and probable benign small polyps [10–12]. The only drawback to this investigation is that it is user dependent and small lesions that may grow rapidly in only a few months will be missed initially.
