Rare Giant Pedunculated Liposarcoma of the Hypopharynx: Case Report and Review of Literature

Abstract

When base of the tumor is located in hypopharynx or cervical portion of the esophagus, and tumor is not aggressive, cervical approach is better, irrespective of the tumor size, except for cases in which an endoscopic approach is feasible.

An atypical lipomatous tumor mimicking a giant fibrovascular polyp of the hypopharynx

“…Endoscopic resection is useful when, as in this case, there is evidence of a tumor peduncle or potential for curative resection. [ 17 , 18 ] Other techniques include excision by lateral pharyngotomy, microlaryngoscopy, or total laryngectomy. The choice of excision technique depends on the accessibility and location of the mass, as well as the ability to resect with wide margins, among other factors.…”

“…[ 19 ] On review of cases in the literature, the majority of these masses has been resected by simple excision or lateral pharyngotomy. [ 18 ] There are reports of late recurrence of liposarcomas which means that long-term follow-up is necessary. The patient in this case was followed up until his death (from unrelated causes).…”

Giant pedunculated oesophageal liposarcomas: A review of literature and resection techniques

“…Endoscopic resection confers the benefit of being less morbid and invasive compared with conventional surgery, especially since the majority of such tumours are pedunculated giant oesophageal polyps arising from a single stalk. Endoscopic techniques described in the literature include (a) using a stabilising retraction suture placed with an endoscopic suturing device followed by division of stalk using ultrasonic shears [1], (b) using a snare with cutting and coagulation [10,13] (c) endoscopic submucosal dissection (ESD) with knife [12,16], and (d) application of hemoclips following diathermy [9]. The subsequent tumour then can either be removed transorally or retrieved via an oesophagotomy or laparotomy if it is too large.…”

Dedifferentiated Liposarcoma in a Giant Esophageal Polyp: A Case Report and Review of the Literature

“…The authors also proposed that surgery should be the primary treatment for patients with esophageal sarcoma due to the survival benefit [11]. A review of eight cases of pleomorphic sarcoma of the esophagus demonstrated a favorable response to radical resection of the tumor [12-13]. Riva et al described a case of an 81-year-old male with DDL who underwent lateral pharyngotomy and resection through a cervical incision, with no endoscopic recurrence at one year [13].…”

Based on our literature review and extrapolation from the above results, surgical or endoscopic resection can be considered as the treatment of choice for esophageal DDLs.…”
