**Core Concept**
Hepatocellular carcinoma (HCC) is a primary malignancy of the liver, and its clinical manifestations are often subtle and non-specific in the early stages. As the tumor grows, it can cause various symptoms and signs due to local invasion, metastasis, and systemic effects.

**Why the Correct Answer is Right**
Hepatocellular carcinoma can present with a wide range of clinical manifestations, including:
* Weight loss and anorexia due to tumor-related cachexia
* Abdominal pain and discomfort due to tumor growth and invasion of nearby structures
* Jaundice and ascites due to bile duct obstruction and portal hypertension
* Palpable abdominal mass
* Hepatomegaly and splenomegaly due to tumor infiltration and metastasis
* Anemia and thrombocytopenia due to tumor-related bone marrow suppression
* Hypoalbuminemia and coagulopathy due to liver dysfunction

**Why Each Wrong Option is Incorrect**
**Option A:** Not mentioned as a common manifestation of HCC.
**Option B:** Not a typical feature of HCC, although it can occur in advanced stages.
**Option C:** Not a direct manifestation of HCC, but can occur in patients with liver cirrhosis or other liver diseases.

**Clinical Pearl / High-Yield Fact**
Hepatocellular carcinoma is often asymptomatic in the early stages, and a high index of suspicion is required for its early detection. Patients with risk factors such as chronic liver disease, hepatitis B and C infection, and alcohol abuse should undergo regular screening with imaging modalities like ultrasound and CT scans.

**Correct Answer:** D
