Systemic generalised lymphangiomatosis: unknown aetiology and a challenge to treat

A case report of a mesenteric cystic lymphangioma in a young adult woman presenting to the emergency room

BACKGROUND

Mesenteric cystic lymphangiomas (MCLs) are rare benign tumours seen in adults. The clinical presentation may vary from asymptomatic to acute abdominal pain with inexplicable abdominal pain, nausea and vomiting.

CASE PRESENTATION

In the current case report, a 22-year old, healthy women presented to the emergency room with acute abdominal pain in need of urgent surgical exploration. Histopathological examination revealed an mesenteric cystic lymphangioma.

CONCLUSION

In patients with inexplicable abdominal pain, the suspicion of MCLs and proper diagnostic strategies are important. The primary treatment of MCLs consists of radical surgical resection to prevent invasion in surrounding tissue. Tertiary referral centres should be consulted to support in the diagnosis, treatment and follow-up of MCLs.

Diffuse abdominal lymphangiomatosis without tumoral masses: a case report

Diffuse abdominal lymphangiomatosis is a rare and complex disease. It typically presents with non-specific gastrointestinal symptoms and characteristic cystic lesions or tumoral masses on imaging based on the literature to date. This report presents the rare case of a young man with an atypical form of diffuse abdominal lymphangiomatosis in the complete absence of cystic lesions or lymphangioma tumoral masses, thus presenting a unique diagnostic challenge. It was successively treated by surgery, gastric electrical stimulator, sirolimus, and imatinib.

Laparoscopy for evaluating mesenteric lymphangiomatosis: A case report

BACKGROUND

Lymphangiomatosis is an extremely rare disease with potential soft tissue, bone, and spleen involvement, which can be characterized by lymphangioma. Only a few cases of colon and mesenteric lymphangiomatosis have been reported. We report a case presenting with fatigue, periumbilical pain, and intermittent bloody stools. This patient underwent a series of examinations. Exploratory laparoscopy, in particular, yielded very valuable images and videos for this disease, which can provide evidence for the diagnosis of this disease.

CASE SUMMARY

The current patient had fatigue, periumbilical pain, and intermittent bloody stools. Colonoscopy indicated numerous variable-sized hyaline cysts in the colon. Submucosal puncture was performed during colonoscopy. The patient was readmitted to the hospital due to periumbilical pain. B-ultrasound and abdominal CT showed multiple hypoechoic nodules in the mesenteric area. Exploratory laparoscopy was performed, and histopathology revealed that D2-40 was positive. Based on auxiliary examination and laparoscopic biopsy, surgeons and pathologists reached the diagnosis of mesenteric lymphangiomatosis.

CONCLUSION

Clinicians need to comprehensively improve their knowledge of lymphangiomatosis, and the combination of clinical symptoms, histological characteristics, and colonoscopy biopsy findings should be considered to improve lymphangiomatosis diagnosis, thereby reducing misdiagnosis.

CORE TIP

Colon and mesenteric lymphangiomatosis is an extremely uncommon benign condition of unknown etiology and pathogenesis in adult patients. We report a case of mesenteric lymphangiomatosis in a 37-year-old woman who presented with fatigue, periumbilical pain, and intermittent bloody stools, as well as lesions in the kidney, spleen, and bones. This case provides new insights into the diagnosis and treatment of this disease.

Genetic and Molecular Determinants of Lymphatic Malformations: Potential Targets for Therapy

Lymphatic malformations are fluid-filled congenital defects of lymphatic channels occurring in 1 in 6000 to 16,000 patients. There are various types, and they often exist in conjunction with other congenital anomalies and vascular malformations. Great strides have been made in understanding these malformations in recent years. This review summarize known molecular and embryological precursors for lymphangiogenesis. Gene mutations and dysregulations implicated in pathogenesis of lymphatic malformations are discussed. Finally, we touch on current and developing therapies with special attention on targeted biotherapeutics.
