# Toxic Megacolon: A Sequelae of Clostridioides difficile Infection in a Case of Necrotizing Fasciitis

## TL;DR

A 56-year-old man with necrotizing fasciitis developed toxic megacolon due to Clostridioides difficile infection, leading to his death due to delayed treatment.

## Contribution

This case highlights the rare but fatal complication of toxic megacolon in necrotizing fasciitis due to C. difficile.

## Key findings

- Necrotizing fasciitis can progress to toxic megacolon due to C. difficile infection.
- Delayed diagnosis and treatment significantly worsened the patient's outcome.
- Antibiotic use may disrupt gut microbiota, promoting C. difficile growth.

## Abstract

Necrotizing fasciitis is an illness that ascends quickly and affects the fascia, subcutaneous tissues, and deeper skin layers. To combat this infection, strong antibiotics are used along with prompt debridement. Frequent usage of such drugs is connected to antibiotic-associated diarrhea and colonic illnesses like colitis. High-spectrum antibiotic usage over an extended period of time can alter the gut microbiota, which promotes the growth of commensal bacteria including Staphylococcus aureus and Clostridioides difficile (previously known as Clostridium difficile) resulting in complications such as toxic megacolon. C. difficile infection can result in extreme inflammation and colon dilatation leading to toxic megacolon. In order to effectively treat necrotizing fasciitis, a timely diagnosis and vigorous management are essential; failing of which may have fatal consequences such as sepsis and even mortality. We present a case of a 56-year-old male, suffering from necrotizing fasciitis of the left lower limb which further complicated to toxic megacolon and caused mortality of the patient. Timely presentation and early diagnosis can be helpful in better prognosis, which in the context of this case was delayed; had the patient presented to the hospital earlier, there were chances of preventing mortality.
