Cervical Cystic Lymphangioma in Young Adults: A Case Report and Literature Review

Cystic lymphangioma is a rare benign congenital malformation of the lymphatic system. It usually presents in childhood and rarely in young adults. Its management lacks consensus, and its prognosis varies depending on the location. We report a case of cervical cystic lymphangioma in a young adult with chronic left lateral cervical swelling. Examination revealed a high jugulocarotid swelling, non-pulsatile, and transilluminable. Radiographic exploration suggested a cystic lymphangioma. Histopathology confirmed the diagnosis. The patient underwent a sclerotherapy session, followed by surgical excision. Our case illustrates a rare presentation of cervical cystic lymphangioma in a young adult and aims to increase awareness of this rare entity and provide literature insights into its diagnosis and treatment in adult patients.

Cystic Lymphangioma of the Mesentery in an Adult: A Case Report and Literature Review

Lymphangiomas are rare benign cystic tumors. Surgical excision is the primary treatment, aiming for complete removal. Diagnosis relies on imaging and histological confirmation. Malignant transformation is exceptionally rare. We report a 25-year-old man admitted for peri-umbilical abdominal pain and an abdominal mass. Imaging revealed multilocular peritoneal cystic formations with infiltration of adjacent mesenteric fat. Laboratory findings were unremarkable, and exploratory laparotomy was performed. A voluminous cystic mass originating from the mesentery was discovered, requiring intestinal sacrifice for complete resection. Immediate postoperative recovery was smooth. Pathological analysis confirmed the diagnosis of mesenteric cystic lymphangioma. The patient had a favorable outcome with no tumor recurrence at a three-year follow-up. We emphasize the significance of complete surgical removal to prevent complications associated with cystic lymphangioma and reduce the risk of recurrence.

A ruptured mesenteric lymphangioma causing peritonitis: a case report

Cystic lymphangioma is a rare disease that is mainly diagnosed in childhood. When diagnosed, the lesion presents an indication for surgery due to the risk of serious complications. Herein, we report the case of a 32-year-old patient who presented to the emergency room for abdominal pain that developed 2 days before with worsening symptoms and abdominal pain in the last 24 hr. The computed tomography showed diffuse wall thickening of the jejunum and proximal ileum with mesenteric fat infiltration, a mesenteric collection, and a moderate volume of ascites extending into the pelvis. A laparotomy was performed, revealing diffuse chemical peritonitis with a crater-like lesion in the jejunal mesentery, secreting lymphatic fluid. The mesenteric lesion was then excised, and the histological examination showed a ruptured cystic lymphangioma. Lymphangiomas of the small bowel mesentery are rare and may be exceptionally associated with bowel occlusion or peritonitis.

Case report and literature review: Giant retroperitoneal cystic lymphangioma

Background

Cystic lymphangioma is a rare benign tumor of the lymphatic system, which is most commonly observed in the neck, head and armpit.Less than 5% of lymphangiomas occur in the abdominal cavity and even less in the retroperitoneum.

Case description

A 65-year-old male patient was diagnosed with an "abdominal mass that had persisted for 1 year, accompanied by abdominal pain, abdominal distension and dyspnea for 7 days". After abdominal computerd tomography, a giant multilobed abdominal lymphangioma was suspected, which squeezed the intestinal canal and was closely related to the inferior vena cava. The patient underwent an exploratory laparotomy, during which, it was found that the tumor formed extensive adhesions to the transverse colon, small intestine and pelvic wall, and enveloped the abdominal aorta, superior mesenteric artery, inferior mesenteric artery and inferior vena cava to varying degrees. It was diffcult to remove the cyst completely. Postoperative pathology confirmed the diagnosis of retroperitoneal cystic lymphangioma. The patient recovered well after the operation, was eating normally by 5 days postoperatively,and was discharged 10 days postoperatively.The patient was followed up 1 month after postoperatively and no evidence of recurrence was observed.

Conclusion

In this case, we report a patient with giant retroperitoneal cystic lymphangioma who underwent exploratory laparotomy combined with preoperative abdominal computerd tomography and acute abdominal pain, abdominal distension and dyspnea. Because of the large volume of the tumor and its close relationship with the superior mesenteric artery and other blood vessels, the surgeon used scissors to separate the tumor sharply and removed the whole tumor completely.

[Cystic hygroma of the neck in a young adult: about a case and literature review]

Cystic hygromas are congenital malformations affecting the lymphatic system. These are rare benign dyssembryoplastic lesions mainly affecting the head and neck, in particular the posterior triangle of the neck. They usually occur during childhood and exceptionally in adults. We here report a clinical case of cystic hygroma of the neck in a 22-year old subject.

Rare huge retroperitoneal cystic lymphangioma presenting as acute abdomen in an adult

Cystic lymphangiomas are rare benign tumors. Most are diagnosed in childhood and their presentation in adults is rare. Retroperitoneal cystic lymphangiomas constitute only 1% of lymphangiomas. Unfortunately the differentiation between cystic lymphangiomas and other cystic tumors is often not possible and surgery with histology is essential for confirmation of diagnosis. A 20-year-old lady with retroperitoneal cystic lymphangioma presented with acute abdomen. In the diagnosis of this patient, abdominal Ultrasound, CT and MRI scans were obtained.
