RESUMO
We report a rare case of extramedullary plasmacytoma (EMP) of the true vocal fold. Our patient, a 62-year-old woman, presented with dysphonia. On workup, fiberoptic laryngoscopy detected a lesion arising from the anterior half of her left true vocal fold. No evidence of other pathology was noted. The patient underwent radical radiotherapy, and the lesion resolved. Follow-up revealed no sign of recurrence. A type of myeloma, EMP is rare, especially in the larynx. To the best of our knowledge, our patient represents the sixth case of glottic EMP to be reported in the literature.

BACKGROUND: Mitomycin C (MMC) inhibits fibroblast proliferation. The objective of this study was to determine the efficacy of MMC in reducing frontal ostium stenosis after endoscopic sinus surgery. METHODS: A prospective open pilot study was conducted in 28 patients who had undergone one or more previous surgical interventions for frontal sinusitis. MMC solution was applied to the frontal ostial region via an endoscopic or combined endoscopic and external approach. Patency of the frontal ostium was evaluated endoscopically during regular follow-up. If restenosis was observed further, endoscopic application of MMC was undertaken. RESULTS: There were 17 men and 11 women (mean age, 51.7 years; range, 26-86 years). Mean number of applications was 1.5 (range, 1:3). Mean follow-up was 19 months (range, 6-32 months). Patency rate was 86%. CONCLUSION: Mitomycin appears to have an important role in reducing postoperative scarring, which may obviate the need for repeated and more extensive surgery.

Laryngo-onycho-cutaneous syndrome is a very rare entity found in Punjabi families. It affects the skin, nails, and larynx. Laryngeal involvement may cause lethal airway obstruction, and has in the past proved very difficult to treat. Mitomycin C is an antibiotic that acts as an alkylating agent, inhibiting DNA synthesis. It reduces fibroblast proliferation, and has previously been used to treat choanal atresia and laryngeal stenosis. We report an 18-year-old man with complete transglottic laryngeal stenosis secondary to laryngo-onycho-cutaneous syndrome. An airway was established by dissection with a bougie and sickle knife, and was initially maintained by the upper limb of a Montgomery T-tube. Laryngeal granulation tissue present on removal of the T-tube was treated with topical mitomycin C (2 mg/mL) applied for 4 minutes on two occasions with an interval of 1 month. A year later, the airway remained patent, with no granulation tissue.
