A case of esophageal lymphangioma in a 75-year-old man who complained of worsening dysphagia is presented. Endoscopic ultrasound showed an echogenic pattern of honeycomb or grid-like multiple microcysts within the submucosa. The sagittal image of computed tomography showed a thickened esophageal wall and fluid retention in the proximal esophageal lumen. Magnetic resonance imaging showed a high signal intensity mass with a septate-like internal structure on T2-weighted imaging and short tau inversion recovery. The tumor was completely resected by endoscopic submucosal dissection. Esophageal lymphangioma is a rare submucosal tumor that can be precisely diagnosed by CT and/or MRI.

BACKGROUND: Lymphangioma is a malformation of superficial lymphatic vessels. Tongue lymphangiomas are relatively uncommon. Multiple treatment modalities have been reported, with variable treatment responses. Most of the traditional treatment modalities have a high recurrence rate.
METHODS: We describe the use of coblation in the management of lymphangioma circumscriptum of the dorsum of tongue in two patients. Radiofrequency ablation of oral lymphangiomas showed early postoperative oral intake and minimal postoperative pain. There was no recurrence of disease on 1 year follow up.
CONCLUSIONS: Improved wound healing, early postoperative oral intake and minimal postoperative pain, make radiofrequency ablation a highly valuable treatment modality for oral lymphangiomas and may be recommended as the treatment of choice.

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.

BACKGROUND: Lymphatic malformations are vascular developmental anomalies varying from local superficial masses to diffuse infiltrating lesions, resulting in disfigurement. Patients\' outcomes range from spontaneous regression to severe sequelae notwithstanding appropriate treatment. The current classification guides, in part, clinicians through the decision-making process, prognosis prediction and choice of therapeutic strategies. Even though the understanding of molecular basis of the disease has been recently improved, a standardized management algorithm has not been reached yet.
RESULTS: Here, we report our experience on five children with different lymphatic anomalies of the head and neck region treated by applying a multidisciplinary approach reaching a consensus among specialists on problem-solving and setting priorities.
CONCLUSIONS: Although restitutio ad integrum was rarely achieved and the burden of care is challenging for patients, caregivers and healthcare providers, this study demonstrates how the referral to expert centres can significantly improve outcomes by alleviating parental stress and ameliorating patients\' quality of life. A flow-chart is proposed to guide the multidisciplinary care of children with LMs and to encourage multidisciplinary collaborative initiatives to implement dedicated patients\' pathways.

Ovarian lymphangiomas are rare benign neoplasms characterized by the proliferation of lymphatic vessels within the ovarian tissue. While lymphangiomas can manifest in various anatomical locations, their occurrence within the ovaries is exceptionally uncommon, posing diagnostic and therapeutic challenges for clinicians. The aetiology of ovarian lymphangiomas remains elusive, with theories suggesting congenital malformations, lymphatic obstruction, or acquired lymphatic proliferation as potential contributing factors. The clinical presentation of ovarian lymphangiomas often includes nonspecific symptoms such as abdominal pain, swelling, or discomfort, leading to difficulties in early detection and diagnosis. Radiological imaging, particularly Ultrasound, CT (computed tomography) and MRI (magnetic resonance imaging), plays a crucial role in identifying these lesions and guiding subsequent management strategies. Despite their generally benign nature, ovarian lymphangiomas can attain significant sizes, causing complications such as torsion, rupture, or compression of adjacent structures. Surgical intervention, typically in cystectomy or oophorectomy, is frequently pursued to alleviate symptoms and prevent potential complications. This paper aims to comprehensively review the existing literature on ovarian lymphangiomas, addressing their clinical presentation, diagnostic challenges, and management strategies. By synthesizing available data, we seek to enhance our understanding of this rare entity, providing valuable insights for clinicians encountering similar cases. Improved awareness and knowledge of ovarian lymphangiomas are essential for timely diagnosis and optimal patient outcomes.

Cystic Hygroma (CH) also referred to as lymphangioma, is a cystic malformation of the lymphatic vessels that can occur anywhere in the body. Its incidence in adulthood is considered rare and its occurrence in the neck is even rarer and only a few case reports are available till date. We present a case of adult CH of the neck and the literature review of the same. A 30-year-old male presented with painless swelling in the left side of the neck of 2 years duration. Investigations showed a cystic mass on the left lower anterior part of the neck which was surgically removed in-toto with the intact capsule. The biopsy report confirmed the diagnosis. A differential diagnosis of CH should be considered when a cystic lesion is encountered in the neck of an adult, cytological and radiological evaluation is necessary for defining its location and diagnosis. Although various conservative modalities of management are available, they are employed only in certain situations, and surgical excision of CH is considered the gold standard. The chances of recurrence range from 15 to 20%.

This case report describes the management of a woman diagnosed with a retroperitoneal cystic tumor during pregnancy. The 29-year-old patient presented at 29 weeks of pregnancy with abdominal pain. A retroperitoneal tumor measuring 224 × 156 × 235 mm was identified on ultrasound and magnetic resonance imaging. The patient underwent cesarean section delivery of a healthy neonate at 37 weeks. Uncomplicated laparoscopic surgery was performed during the postpartum period, resulting in a histologic diagnosis of a retroperitoneal lymphangioma. A review of articles published between 2003 and 2023 on the diagnosis, management, and prognosis of gestational lymphangiomas was conducted using the PubMed, SCOPUS and SpringerLink databases. Ten articles, including case reports of lymphangiomas diagnosed during pregnancy, were identified. The most frequent location was the gastrointestinal tract, with no cases reported in the retroperitoneal area. A good perinatal outcome was reported in the majority of cases. Lymphangiomas are rare benign tumors that are even more uncommon during pregnancy. Watchful waiting can offer a good obstetric and perinatal prognosis.

Neoplasms of the tongue are relatively common, and the vast majority are epithelial in phenotype. Although uncommon, a diverse and distinctive array of mesenchymal neoplasms arises in this anatomic site. To increase our understanding of these lesions, we reviewed our experience of MNs of the tongue and described their clinicopathologic features. The pathology archives from 2005 to 2021 and the consultation files of one of the authors were queried for all MNs of the tongue. We reviewed the histologic slides and ancillary studies and obtained clinical data from the available medical records. Ninety-three cases were identified, and they form the study cohort - to our knowledge, this is the largest series of mesenchymal neoplasms of the tongue. Forty-eight patients were female, and forty-five were male, with a mean age of 51 years (range: 1-94 years). The tumors included 43 (46.2%) hemangiomas, 14 (15%) granular cell tumors, 8 (9%) lipomas, 4 (4.3%) schwannomas, 4 (4.3%) solitary fibrous tumors - all with low risk of progression based on risk stratification criteria, 2 (2.2%) lymphangiomas, 3 (3.2%) Kaposi sarcomas, 2 (2.2%) chondromas, 2 (2.2%) myofibromas, 1 (1.1%) solitary circumscribed neuroma, 1 (1.1%) perineurioma, 1 (1.1%) neurofibroma, 1 (1.1%) ectomesenchymal chondromyxoid tumor, 1 (1.1%) atypical glomus tumor with a NOTCH2 rearrangement and TLL2 mutation, 1 (1.1%) spindle cell rhabdomyosarcoma, 1 (1.1%) pleomorphic fibroblastic sarcoma, 1 (1.1%) malignant rhabdoid tumor, 1 (1.1%) leiomyosarcoma, 1 (1.1%) angiosarcoma, and 1 (1.1%) alveolar soft part sarcoma. Most of the patients underwent surgical excision, and 1 patient (with hemangioma) underwent embolization. On follow-up, the patient with spindle cell rhabdomyosarcoma developed postoperative numbness at the surgical site and was disease-free through 17 months of follow-up. The patient with leiomyosarcoma declined adjuvant radiation and developed metastasis to the lung at 22 months. The patient with alveolar soft part sarcoma had metastases to the lung at the time of diagnosis and received adjuvant chemotherapy. The remaining patients had no local or distant recurrence. MNs of the tongue are usually benign and characterized by either endothelial, adipocytic, or schwannian differentiation. The mainstay of treatment is surgical excision with the extent of excision determined by tumor type. Adjuvant therapy is reserved for high-grade sarcomas.

Isolated splenic lymphangiomas are rare benign lesions mostly seen in children are exceptionally rare in adults, often discovered incidentally due to their typically asymptomatic nature. This case report elaborates on the surgical excision of a rare splenic cystic lymphangioma in a 33-year-old woman, underscoring the diagnostic and therapeutic challenges these tumors pose. The patient\'s symptoms, abdominal pain and a palpable mass led to imaging through ultrasound and CT, which revealed a cystic splenic lesion. Total splenectomy was performed, revealing a large cystic mass, with pathological examination confirming a cystic lymphangioma. This case emphasizes the necessity of considering splenic lymphangiomas in adult patients presenting with splenic lesions. It also highlights the critical role of surgical interventions for definitive diagnosis and to prevent complications such as rupture and hemorrhage, thereby emphasizing on the complexity of managing rare splenic tumors.
