Giant vulvar lipoma in an adolescent girl: a case study and literature review

A case of giant labia majora lipoma in an adult

Lipomas are common benign adipose tissue tumors but are infrequently found in the labia majora, especially at a large size. We report a case of a giant lipoma of the labia majora in a 37-year-old woman diagnosed by imaging methods and successfully treated by surgery. This case highlights the importance of considering lipoma in the differential diagnosis of labial masses and underscores the role of imaging in diagnosis. They need to be differentiated from liposarcoma or omental herniation into Nuck's canal. It also demonstrates the effectiveness of surgical management for large lipomas in sensitive areas, with attention to both medical and aesthetic outcomes.

Giant lipoma in the Retzius space resected under laparoscopy: A case report

Lipoma is a common type of benign soft tissue tumor that can occur in the shoulders, neck and back, in addition to other body parts. The Retzius space is a small anatomical space between the pubic symphysis and the bladder located extraperitoneally and filled with loose fatty connective tissue. Giant lipomas are rare in the Retzius space. A 61-year-old Chinese male arrived at Beijing Yanhua Hospital (Beijing, China) due to frequent urination, and CT scan images of the lower abdomen observed a large pelvic mass and left inguinal hernia. Preoperative clinical manifestations and auxiliary examination suggested that the tumor originated from the urinary bladder wall. The maximum tumor diameter was ~25 cm and abdominal pressure was increased. Therefore, laparoscopic pelvic tumor resection combined with inguinal hernia repair was attempted. Intraoperatively, the tumor was found to originate from the Retzius space and the postoperative pathological diagnosis was lipoma. The present case report may serve as a reference for minimally invasive treatment of this type of rare disease in future.

Unilateral Giant Vulvar Lipoma with Fat Necrosis Not Visualized on Magnetic Resonance Imaging (MRI)

BACKGROUND A subcutaneous lipoma is a benign tumor comprised of mature adipocytes. Clinically it presents as a soft, freely moveable, doughy mass that is typically painless and slow growing. Lipomas containing fat necrosis and corresponding palpable nodular elements are rare and suggest an alternative diagnosis. Lipomas in the vulvar region are rare and giant vulvar lipomas with palpable fat necrosis are unreported. CASE REPORT A 25-year-old patient presented with a 4-year history of an enlarging right vulvar mass with multiple small (<1 cm) firm nodules within the tumor. A pelvic MRI (magnetic resonance imaging) did not visualize the nodules but histopathologic examination revealed a benign lipoma containing fat necrosis and discrete areas of calcium deposition. CONCLUSIONS Fat necrosis can occur in vulvar lipomas and present with intratumor nodularity. MRI imaging, clinical findings and histology may be discordant.
