OBJECTIVE: De novo occurrence of granuloma (granulation tissue) on the membranous vocal fold is not readily explained by usual causes of granuloma at the vocal process. We describe a series of patients.
STUDY DESIGN: Case series.
SETTING: Single academic institution.
METHODS: Cases were identified over a 16-year period. All patients exhibited granulation tissue on pathology. Demographic details, presentation, treatment, histology, and clinical outcomes were recorded.
RESULTS: Five patients (mean age: 74.0 ± 6.1 years, 40.0% male, 40.0% former smokers) underwent a biopsy. Persistent or recurrent granulation led to a second biopsy in 4 patients an average of 1423.5 days later, revealing a new diagnosis of squamous cell carcinoma (SCC) in situ in one and mild dysplasia in another. Further persistence or recurrence led to a third biopsy or excision an average of 302.3 days later in 3 patients, demonstrating SCC in situ in 1. An average of 2.5 biopsies were required with a mean time to SCC in situ diagnosis of 919.5 days from presentation. Two patients continued to demonstrate persistent granulation tissue on histology.
CONCLUSION: The membranous vocal fold is an atypical location for granuloma and portends a risk of occult malignancy. The occurrence of de novo granuloma at this site should prompt close long-term clinical surveillance with a low threshold for biopsy. Consideration should be given to tissue collection in the operating room to adequately sample the lesion's base. Concern should persist even after a negative biopsy, and serial observation with repeat biopsy as needed should be pursued.
