40-year-old immunocompromized patient presented with complaints of dysphagia. UGI scopy showed multiple ulcers in the distal esophagus. Biopsy from the esophagus showed the following. What is the diagnosis?
**Core Concept**
The patient's symptoms and biopsy findings suggest an opportunistic esophageal infection in an immunocompromised individual, highlighting the importance of considering fungal pathogens in patients with weakened immune systems.
**Why the Correct Answer is Right**
The presence of multiple ulcers in the distal esophagus, along with the patient's immunocompromised status, is highly suggestive of esophageal candidiasis. This condition is caused by the overgrowth of Candida albicans, a type of fungus, in the esophagus. The pathogenesis involves the adhesion of Candida to the esophageal mucosa, followed by the production of enzymes that break down the mucosal barrier, leading to ulceration.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while cytomegalovirus (CMV) can cause esophageal ulcers in immunocompromised patients, the biopsy findings would typically show characteristic viral inclusions and not the typical fungal morphology seen in candidiasis.
**Option B:** This option is incorrect because herpes simplex virus (HSV) can cause esophageal ulcers, but the biopsy findings would typically show characteristic viral cytopathic effects, such as multinucleated giant cells, and not the typical fungal morphology seen in candidiasis.
**Option C:** This option is incorrect because while esophageal tuberculosis can cause ulcers, the biopsy findings would typically show granulomatous inflammation and not the typical fungal morphology seen in candidiasis.
**Clinical Pearl / High-Yield Fact**
In immunocompromised patients, the presence of multiple ulcers in the distal esophagus should raise suspicion for esophageal candidiasis, and a biopsy should be performed to confirm the diagnosis.
**Correct Answer:** C. Candida esophagitis.
