The lipomas of oropharynx, hypopharynx, and larynx are so rare that up to now approximately there have been 100 cases reported. The lipomas are slow-growing lesions that are capable of reaching considerable dimensions and are often detected at a late stage. The symptoms can vary both in dimension and in location, semiobstructing the aerodigestive tract or exerting compression on adjacent structure. In this case, the lesion, which originated from the piriform sinus, was removed endoscopically urgently due to obvious signs of tissue suffering caused by stretching of the pedicle as a result of displacement of the mass. The two aims of this case report are to expose an interesting and rare case study mainly for an Emergency Room Specialist and an ENT (Ear, Nose, and Throat) Specialist involved in solving the problem and to demonstrate that the choice of an endoscopic approach is useful in order to have an optimal visualization of the lesion and to perform a total eradication. The use of endoscopic devices also allows a rapid postoperative recovery, compared to external access and optimum locoregional control in the follow-up procedures to prevent possible relapses.
HighlightsOssifying fibromyxoid tumor of soft parts (OFMT) has an uncertain histopathogenesis and is characterized by a peripheral bone shell embedded in a fibromyxoid matrix.Folpe and Weiss proposed a classification with “typical”, “atypical” and “malignant” variants.The exam revealed a right perimastoid mass formation (2.2 × 1.2 × 2 cm) with an oval morphology, extended right to the back of the external ear canal, characterized by the predominant calcific component.The cytoplasm is described as a poorly eosinophilic, arranged to form solid nests and cords immersed in abundant collagenous and/or myxoid stroma, interposed in a mature irregularly shaped trabecular bone.Considering that it is extremely rare, and the possibility of local metastasis especially for the malignant type, we believe that more studies are required for this “enigmatic” tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
