case_images: During the first consultation, the protrusion of a well-defined elongated mass was confirmed via oral cavity with the Valsalva maneuver (Figure 1).

case_images: Under general anesthesia, intraoperative esophagoscopy was performed with identification of the pedunculated mass dependent on the left cricopharyngeal region and extrusion by means of an endoscopic loop; the lesion was resected from its pedicle with harmonic scalpel (Figures 2 and 3).

case_images: The histological analysis of the lesion revealed a 6 x 2.5 x 1.5 mm dependent soft-tissue, polypoid circumscribed lesion, lined by stratified squamous epithelium without dysplasia, constituted by spindle cells without atypia and mature adipose tissue, without observing atypical mitosis (Figure 4).

case_images: The immunohistochemical profile revealed positivity of spindle cells for CD34, negativity for S100, and a low proliferation with Ki57, which confirmed the diagnosis of spindle cell lipoma and revealed its benign behavior (Figure 5).
