Abstract
Mature teratomas are unique and generally benign neoplasms. They are derived from embryonic tissues and typically located within the gonadal region. Primary retroperitoneal teratomas are uncommon in adults and often challenging to treat, given their location and size. Here, we offer a rare case of a large primary retroperitoneal mature cystic teratoma, detected on abdominal ultrasound during the work-up of abdominal bloating and nausea and treated with robot-assisted laparoscopic excision in a 58-year-old male. In this report, we sought to describe the evaluation, treatment, and follow-up of this condition, as well as review the associated literature.
Highlights
Within the realm of neoplasms, teratomas are a rarity and consist of two or more cell types from the three germ layers [1]
Teratomas tend to occur in the gonads [2]; when extragonadal, they can occur at midline structures within the head, neck, mediastinum, sacrococcygeal regions, and retroperitoneum [1,2,3,4,5]
We present a rare case of a large primary retroperitoneal mature cystic teratoma in a 58-year-old male, successfully managed with robot-assisted laparoscopic removal
Summary
Within the realm of neoplasms, teratomas are a rarity and consist of two or more cell types from the three germ layers (endoderm, mesoderm, or ectoderm) [1]. We present a rare case of a large primary retroperitoneal mature cystic teratoma in a 58-year-old male, successfully managed with robot-assisted laparoscopic removal. As the patient had no improvement on medical therapy, an abdominal ultrasound was obtained which revealed a large renal cyst. How to cite this article Blazek A, Plambeck B, Lele S, et al (July 12, 2021) Robot-Assisted Laparoscopic Removal of a Large Primary Retroperitoneal Mature Cystic Teratoma in an Adult. The patient had a past medical history significant for a left, non-toxic thyroid nodule discovered on ultrasound in February 2021 He had no history of abdominal surgery or genitourinary operations. We performed a right robot-assisted excision of a cystic retroperitoneal mass. Findings are consistent with the diagnosis of a cystic teratoma
