**Question:** True regarding Felty's syndrome is all, EXCEPT:

**Core Concept:** Felty's syndrome is a rare complication of chronic inflammatory arthritis, particularly rheumatoid arthritis (RA), characterized by neutropenia (a decrease in neutrophil count), and enlargement of the spleen, leading to increased susceptibility to infections.

**Why the Correct Answer is Right:** Felty's syndrome is a specific condition that occurs in patients with RA, where the spleen enlarges and neutrophil count decreases. The correct answer should reflect the core concept of Felty's syndrome, which includes the association with RA and the characteristic features of splenomegaly and neutropenia.

**Why Each Wrong Option is Incorrect:**

A. Neutropenia is a common feature of Felty's syndrome, but option A is incorrect because it does not address the specific association with RA and the enlarged spleen.
B. Splenomegaly is a hallmark of Felty's syndrome, but option B does not address the relationship with RA.
C. Although RA is a key aspect of Felty's syndrome, option C is incorrect because it does not specifically mention the characteristic feature of neutropenia.
D. Neutrophil count is reduced in Felty's syndrome, but option D is incorrect as it does not address the relationship with RA and the enlarged spleen.

**Clinical Pearl:** Felty's syndrome is a critical aspect of the management of patients with RA, particularly when considering the risk of infections due to neutropenia. Prompt diagnosis and treatment can prevent severe infections and their complications.

**Correct Answer:** .

**Answer:** C. Although rheumatoid arthritis (RA) is a key aspect of Felty's syndrome, the correct answer focuses on the characteristic feature of neutropenia, which is not mentioned in option C. Felty's syndrome is characterized by the combination of rheumatoid arthritis and splenomegaly, along with neutropenia, leading to increased susceptibility to infections.
