L. Lassaletta et al., SYNCHRONOUS GLOTTIC GRANULAR-CELL TUMOR AND SUBGLOTTIC SPINDLE-CELL CARCINOMA, Archives of otolaryngology, head & neck surgery, 124(9), 1998, pp. 1031-1034
We report the clinicopathologic findings in a case of coexistent glott
ic granular cell tumor and subglottic spindle cell carcinoma. There is
no evidence in this case that suggests malignant transition of the gr
anular cell tumor to malignant tumor. To our knowledge, this is the fi
rst report of synchronous granular cell tumor and subglottic spindle c
ell carcinoma.
