Summary
Primary hepatic melanoma, a rare liver cancer, presents diagnostic challenges due to vague symptoms. This case highlights the importance of thorough investigation for accurate diagnosis and improved patient outcomes.
Area of Science:
- Hepatobiliary Medicine
- Surgical Oncology
- Dermatology
Background:
- Primary hepatic melanoma is an exceptionally rare malignancy.
- It is characterized by aggressive behavior and poor prognosis.
- Diagnosis is often delayed due to nonspecific clinical and imaging features.
Purpose of the Study:
- To report a rare case of primary hepatic melanoma in a young North Indian woman.
- To discuss the diagnostic challenges associated with this rare condition.
- To review existing literature to enhance awareness and understanding.
Main Methods:
- Case presentation of a 26-year-old female with abdominal pain.
- Utilized triple-phase computed tomography (CT) scan for abdominal imaging.
- Performed histopathological evaluation and immunohistochemistry on liver biopsies.
Main Results:
- CT scan revealed hepatomegaly and two liver lesions.
- Histopathology identified a malignant tumor with intracytoplasmic pigment.
- Immunohistochemistry confirmed the tumor as melanoma.
Conclusions:
- Primary hepatic melanoma is extremely rare and difficult to diagnose preoperatively.
- Low index of suspicion and nonspecific symptoms contribute to diagnostic challenges.
- This case underscores the need for comprehensive evaluation to differentiate from metastatic disease.
