Malignant hepatic infiltration is a very rare cause of fulminant hepatic failure (FHF). Liver metastases are diagnosed in up to one-third of patients with advanced melanoma and are associated with a worse prognosis. To our knowledge, this is the first report that shows a FHF by diffuse melanoma infiltration in a patient with a breast cancer history. Interestingly, epidemiologic and genetic studies have suggested an association between breast cancer and melanoma. ,
A 44-year-old hispanic woman was admitted with a 2-week history of abdominal pain, jaundice, acolia, and coluria. She had a medical history of breast cancer 5 years earlier, which had been treated by total mastectomy plus axillary lymph node dissection, bilateral oophorectomy, and radiochemotherapy. Since then, she had been taking tamoxifen. At admission, the liver was palpable 10 cm below the right costal margin. Abdominal computed tomography showed marked hepatomegaly without focal lesions and an extensive infiltrative process [Figure 1]a. Due to the cancer history, hepatic metastasis of breast cancer was suspected, and a liver biopsy was indicated. Unfortunately, the patient's clinical course began to worsen rapidly and she died from FHF. Autopsy revealed that the liver, spleen and perihepatic lymph nodes were black-colored [Figure 1]b and c. Due to the fact that the metastatic malignant melanoma was considered, we investigated the whole body, including mucosal surfaces (e.g., gastrointestinal, genitourinary, and nasopharyngeal tract) and skin. Nevertheless, no primary site was found. Histologically, malignant melanoma cells had infiltrated diffusely into the liver, spleen and perihepatic lymph nodes [Figure 2]a and b and stained positively for HMB-45 and S-100 proteins and negatively for estrogen and progesterone receptors [Figure 2]c-f.

Diffuse hepatic melanoma infiltration is less common than other malignancies such as hematological malignancies and adenocarcinomas. , Taking into account that no nodular lesions are found by imaging studies, a noninvasive diagnosis is usually difficult and requires a high degree of suspicion. These cases have a high mortality rate and are often diagnosed postmortem, and death is a direct result of FHF.
Sometimes, melanoma occurs as apparent metastasis to lymph nodes or viscera with an unknown primary origin. This clinical presentation can be found in 3.7% of melanoma cases. Cutaneous malignant melanoma can have a partial or complete regression. Therefore, the possibility of a regressed skin lesion cannot be ruled out in our patient.
A bidirectional association between breast cancer and melanoma has been reported. , This raises the possibility of a common genetic predisposition for both tumors. CDKN2A mutation positive melanoma families have a 3.8-fold increase in frequency of breast cancer.  Furthermore, BCR2A mutation carriers have an increased risk of melanoma with a relative risk ranging from 2.58 to 99.4. , Interestingly, young female breast cancer patients and treatment with radiation have an increased risk for subsequent cutaneous melanoma. In our case, the patient had these two conditions.
In conclusion, awareness should be raised amongst clinicians of the potential association between these two malignancies and the need for careful screening of patients with melanoma or breast cancer history emphasized. This medical practice may detect early stages of the disease, so appropriate interventions can be done with a potentially curative treatment.
