All are true regarding Plummer Vinson syndrome,except –
**Core Concept**
Plummer-Vinson syndrome is a rare condition characterized by a triad of dysphagia, iron-deficiency anemia, and esophageal webs. It is a clinical entity that involves the upper gastrointestinal tract and is often associated with chronic iron deficiency.
**Why the Correct Answer is Right**
The pathophysiology of Plummer-Vinson syndrome is not fully understood, but it is believed to involve chronic iron deficiency leading to atrophy of the mucosa in the esophagus, which can result in the formation of esophageal webs. These webs are thin, membranous structures that can cause dysphagia, especially to solids. The iron deficiency can also lead to impaired wound healing and tissue repair, contributing to the development of esophageal webs.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a true statement regarding Plummer-Vinson syndrome. The condition is indeed associated with iron-deficiency anemia, which is a key component of the syndrome.
**Option B:** This option is incorrect because it is a true statement regarding Plummer-Vinson syndrome. Dysphagia is a common symptom of the condition, often presenting as difficulty swallowing solids.
**Option C:** This option is incorrect because it is a true statement regarding Plummer-Vinson syndrome. Esophageal webs are a hallmark feature of the condition and can cause significant symptoms.
**Option D:** This option is the correct answer because it is the statement that is not true regarding Plummer-Vinson syndrome. While the condition is associated with iron-deficiency anemia and dysphagia, it is not typically associated with diabetes mellitus.
**Clinical Pearl / High-Yield Fact**
Plummer-Vinson syndrome is often associated with a history of chronic iron deficiency, and patients may present with symptoms of dysphagia and weight loss. A high index of suspicion is necessary for diagnosis, as the condition is rare and can be easily missed.
**Correct Answer:** D.
