Focal hemolymphangioma of the rectum: A case report and literature review.

RATIONALE: Gastrointestinal hemolymphangiomas are very rare, especially in the rectum. Only 3 cases of rectal hemolymphangioma, all of which are diffuse lesions, have been reported in the English literature on PubMed. Our case is the first focal lesion of the rectum. It is important for radiologists to correctly identify the imaging features of rectal hemolymphangiomas. PATIENT CONCERNS: A 51-year-old woman visited our hospital because of intermittent constipation for 3 years. DIAGNOSES: Colonoscopy revealed a prominent lesion on the left anterior wall of the lower rectum. Transvaginal color Doppler ultrasonography showed that the posterior vaginal wall area had a mixed-echo mass, and blood flow signals of the dots and stripes could be seen. Pelvic magnetic resonance imaging showed that the cystic space-occupying lesion in the region between the left anterior wall of the lower rectum and the posterior wall of the middle and lower vagina had a clear boundary. INTERVENTIONS: The patient underwent surgery to remove the rectal lesions. The surgical specimen was finally diagnosed as local hemolymphangioma by pathological analysis. LESSONS: Localized hemolymphangioma of the rectum is very rare, and imaging examination is essential for the diagnosis and evaluation of the extent of lesion invasion.

Gastric lymphangioma. Diagnosis by endoscopic resection of a foreign entity.

The lymphangioma is a rare and very uncommon benign tumor at the gastric level. Its diagnosis typically involves imaging tests and endoscopy, and its treatment usually involves surgery. We present a case of an 82-year-old patient who presented with chronic anemia, with a large gastric polyp detected during the initial gastroscopy. Subsequently, an endoscopic resection was performed, confirming histologically that it was a lymphangioma.

Unexpected Axillary Lymph Node Uptake During Lower-Limb Lymphoscintigraphy in a Case With Vulvar Lymphangioma Circumscriptum.

ABSTRACT: Lymphoscintigraphy is a safe, minimally invasive, and well-established imaging modality for evaluating lymphatic drainage in patients with suspected lymphedema. We report a case of an 8-year-old girl with lymphangioma circumscriptum of the labium majora. She was referred to lymphoscintigraphy for swelling of the lower extremities. Scintigraphy showed widespread dermal backflow at bilateral lower limbs, aberrant uptake in the abdominal lymph nodes, and unexpected uptake in the right axillary lymph nodes.

Skull Base Fracture or Abuse Suspicion Based on Intraorbital Lymphangioma Secondary to Periorbital Hematoma.

Intraorbital lymphangiomas are among the orbital tumors that can cause sudden eye protrusion in children. In children with periorbital hematoma (panda eye sign), a skull fracture or abuse is likely first considered as the differential diagnosis. A 7-month-old boy presented to the ophthalmologist with complaints of swelling of the right upper eyelid, subconjunctival hemorrhage on the right ear side, and periorbital subcutaneous hemorrhage, which had appeared since the morning of the day before the visit. The eyeball did not protrude. Based on the interview and clinical findings, right eyeball contusion was suspected. The patient was then followed up for observation. Later, during the physical examination, the abovementioned symptoms were noted. Hence, the patient was admitted for a close examination based on the suspicion of skull base fracture and abuse. Contrast-enhanced magnetic resonance imaging (MRI) after admission revealed a multifocal cystic structure within the right intraorbital muscular cone. Thus, he was diagnosed with right intraorbital lymphangioma. Intraorbital lymphangioma may not show ocular protrusion, and this disease should be considered in cases where abuse is suspected, considering the periorbital subcutaneous hemorrhage.

[Lymphangioma of the scrotum].

INTRODUCTION: Lymphangioma (lymphatic malformation) is a congenital malformation of lymphatic vessels. According to the classification of the International Society for the Study of the Vascular Anomalies, there are macrocystic, microcystic and mixed types of lymphatic malformations. The typical location of the lymphangiomas is the area of large lymphatic collectors (head, neck, axillary areas), while the scrotum is not frequently affected. AIM: To present a rare clinical case of lymphatic malformation of the scrotum with successful minimally invasive treatment (sclerotherapy). MATERIALS AND METHODS: A clinical observation of a 12-year-old child with a diagnosis of "Lymphatic malformation of the scrotum" is presented. From the age of 4, there was a large lesion in the left half of the scrotum. In other clinic, a surgical removal with a diagnosis of "left-sided inguinal hernia", "spermatic cord hydrocele", "isolated left-sided hydrocele" was performed. However, there was a recurrence after the procedure. When contacting the Clinic of pediatrics and pediatric surgery, scrotal lymphangioma was suspected. The diagnosis was confirmed by magnetic resonance imaging. The patient underwent minimally invasive sclerotherapy using the drug "Haemoblock". After 6 months of follow-up, no relapse was seen. CONCLUSION: Lymphangioma (lymphatic malformation) of the scrotum is a rare urological pathology that requires specific diagnosis, in-depth differential diagnosis and treatment by a multidisciplinary team of doctors, including a specialist in the treatment of vascular pathology.

CONGENITAL LYMPHANGIOMA OF THE FOOT MIMICKING MULTIPLE VIRAL WARTS: DERMATOSURGICAL APPROACH WITH SECONDARY WOUND HEALING AND FAVOURABLE FINAL OUTCOME.

The problems with lymphangiomas in general stem from the fact that on the one hand they most often show an atypical clinical picture, and on the other hand their localization does not always allow the desired complete surgical removal. Lymphangiomas are rare and benign tumors of the lymphatic vessels. In the higher percentage of cases, they are defined as congenital malformations. The acquired type can manifest due to a variety of external factors, resulting in a benign distinct lesion, which can often be mistaken for another benign or malignant one. Although benign and even surgically treated , the recurrence rate is high. The pathogenesis of these tumours is unclear and is presumed to be due to an error in the fetal/embryonal development. Nosologically, these lesions belong to the group of so-called low flow lesions. Within the framework of their differentiation, it is important to distinguish them from hemangiomas and venous malformations, as although overlapping to some extent, at times- therapeutic options differ. This differentiation is most adequately accomplished by the application of MRI and Doppler, necessarily accompanied by histopathologic verification of the lesion. Spontaneous regression, although rare, occurs in up to 6% of cases. Surgical removal remains the safest method of treatment to date, and according to the literature this is possible in only 18 to 50% of cases. Often, however, the atypical clinical presentation of some of the lesions could be confusing for clinicians and could be the reason for prolonged and unsuccessful conservative or semi-invasive therapy. We present a 23-year-old patient with a history of complaints of more than 15 years in the form of itching, burning, and discomfort in the left foot area. The finding was treated under the diagnosis of viral warts with variable results and subsequent achievement of short-term remissions for no more than 5 -6 months. Due to an increase in pain symptomatology and an increase in the size of the lesion after the last cryotherapy, a skin biopsy was taken to confirm the diagnosis of lymphangioma. During hospitalization, the patient underwent MRI/Doppler of the vessels to determine the depth of infiltration and the presence/exclusion of communication to larger vascular formations for preoperative planning. Surgery was performed with secondary wound healing resulting in a favourable outcome.

Fluorescence imaging of lymphangioma circumscriptum of the vulva with aminolevulinic acid and target-type narrow band ultraviolet light.

Lymphangioma circumscriptum of the vulva is a rare lymphatic disorder. Defining the precise location of the lesion is required to select an appropriate treatment. Herein we present photodynamic diagnosis of lymphangioma circumscriptum of the vulva with aminolevulinic acid and target-type narrow band ultraviolet light device.

Creeping mediastinal lymphangioma transgressing anatomical compartments: A rare case in an adult female patient.

Lymphangiomas, also known as lymphatic malformations, are rare non-neoplastic lesions of vascular origin showing lymphatic differentiation. These are most commonly reported in children within the neck and axillary region; however, mediastinum remains the commonest site in adults whereby diagnosis is usually incidental on imaging done for non-specific symptoms. Radiologically, these lesions are well-defined multicystic non-enhancing masses, with CT attenuation values ranging from simple to complex fluid and fat. Being benign, these mostly present clinically either due to mass effect exerted on structures, secondarily infected or developing intra lesion haemorrhage. We present a rare case of mediastinal lymphangioma with secondary hilar and intrapulmonary extension in a middle-aged female presenting with occasional haemoptysis and shortness of breath. The patient underwent thoracotomy with complete dissection of the mediastinal tumour, per operative Bleomycin administration in pulmonary component, and made subsequent uneventful post-operative recovery.

Retroperitoneal lymphangioma as the final diagnosis of a middle-aged woman with abdominal pain: a case report.

BACKGROUND: Lymphangiomas are lesions attributed to congenital malformations of the lymphatic system, or acquired chronic obstruction of the lymphatic network due to trauma, radiation, surgical manipulation, inflammation, or infection. Overall, lymaphangiomas are rare, and particularly, retroperitoneal lymphangiomas are far more uncommon per reported cases. CASE PRESENTATION: A 49-year-old Iranian woman presented with a progressive abdominal pain since approximately 1 month before admission. She was found to have a retroperitoneal lymphangioma after a precise radiological and surgical workup. CONCLUSION: Retroperitoneal lymphangiomas are rare lesions, sometimes indistinguishable from malignant lesions originating from pancreas and adjacent organs. Complete surgical removal and histologic evaluation of the lesion is the gold standard of treatment and diagnosis.

Jejunal lymphangioma.

We herein report a case of jejunal lymphangioma. A CT scan showed non-enhancing cystic masses in the jejunum. Enteroscopy revealed multiple cystic swelling with whitish carpet-like villi. Histopathology disclosed dilated lymphatic channels, lined by a single layer of endothelial cells, which were positive for the lymphatic endothelial marker by the immunohistochemical staining. Clinical manifestations of intestinal lymphangioma are briefly discussed.

Review of diagnosis, differential diagnosis, and management of retroperitoneal lymphangioma.

Lymphatic malformation (LM) is the currently preferred term for what was previously known as lymphangioma. Retroperitoneal LMs are extremely rare, benign, cystic masses that arise from lymphatic vessels. They can be challenging to diagnose because they resemble other retroperitoneal cystic tumors. The development of treatment strategies for rare diseases, including retroperitoneal LM, requires the acquisition of new knowledge to enhance our understanding of the disease progression. Therefore, we present an update regarding fundamental and advanced issues associated with retroperitoneal LM. This review describes the epidemiology, histopathology, biomedicine, clinical manifestations, radiological features, differential diagnosis, and management of this lesion.
