Given these benign findings, no further treatments were recommended.Ħ8-year-old male with a six month history of dysphoniaĢ.6 cm mass in the right vestibular fold and ventricleĦ3-year-old male with a several month history of snoring and dyspneaĢ.7 cm mass that was pedicled at the left aryepiglottic fold that ball-valved into the glottis causing partial obstructionĦ5-year-old male with a two week history of dysphonia, dyspnea and stridor These features together are diagnostic of a spindle cell lipoma. The adipocytes were uniformly mature and stained positively for S100 (data not shown). 3d and data not shown) more than 50% of stromal cells demonstrated loss of the phosphorylated retinoblastoma protein (pRb) (Fig. Regardless of pattern, the stromal cells stained uniformly positive for CD34 and negative for S100 (Fig. 3c), and (3) purely lipomatous areas (the least frequent pattern Fig. Adipocytes and stroma were present in three patterns: (1) an admixture of adipocytes with fibrous cords (predominant pattern Fig. 3a), consisting of mature adipocytes and uniform, bland spindle cells arranged in collagen-rich fascicles with occasional thick ropey collagen strands. Microscopic examination showed a fairly well-circumscribed mass underlying unremarkable squamous mucosa (Fig. The left supraglottic lesion measured 3.0 cm by 2.0 cm by 1.5 cm the right lesion measured 2.0 cm by 1.5 cm by 1.5 cm. Gross pathology of the lesions demonstrated soft, ovoid masses with red-tan to white-tan cut surfaces (Fig. He was subsequently decannulated prior to discharge with relief of airway difficulties and dysphagia. Both masses were excised endoscopically with CO 2 laser. In the operating room, the patient underwent tracheostomy followed by direct laryngoscopy, which revealed a left supraglottic mass encroaching on the left pharynx as well as a separate right supraglottic mass.
