Laryngeal and Subglottic Necrosis Following Long-Term Heroin Inhalation.

Area of Science:

• Otolaryngology
• Oncology
• Toxicology

Background:

• Nasal and palatal necrosis from cocaine use is documented.
• Laryngeal necrosis linked to heroin abuse is rarely described and previously unreported.
• Substance abuse is a significant factor in head and neck pathologies.

Purpose of the Study:

• To report a rare case of laryngeal necrosis secondary to heroin abuse.
• To highlight the importance of considering heroin abuse in the differential diagnosis of laryngeal necrosis.
• To emphasize the link between long-term substance abuse and the development of laryngeal malignancy.

Main Methods:

• Case presentation of a 48-year-old male with a history of heroin abuse.
• Laryngoscopic evaluation revealing necrotic debris on vocal cords and subglottic region.
• Surgical debridement for diagnosis and symptom management.
• Biopsy for histopathological examination.
• One-year follow-up revealing subglottic adenocarcinoma.

Main Results:

• The patient presented with symptoms of dysphonia and dyspnea due to laryngeal necrosis.
• Debridement provided subjective symptom improvement.
• A subglottic adenocarcinoma was diagnosed one year after initial presentation.
• Necrotic laryngeal tissue in patients with substance abuse warrants thorough investigation.

Conclusions:

• Heroin abuse should be considered in cases of unexplained laryngeal necrosis.
• Biopsy and debridement are essential for diagnosis and management of laryngeal necrosis.
• Long-term follow-up is critical due to the potential for malignancy development in patients with a history of substance abuse.
