Byline: Aba F. Uba (1), Lohfa B. Chirdan (1) Keywords: Lymphangioma; Children; Head and neck Abstract: The management of cystic lymphangiomas (CL), especially in the head and neck region, presents challenges to the pediatric surgeon. This is a retrospective study of all children seen with lymphangioma at the Pediatric Surgical Unit of the Jos University Teaching Hospital from 1996 to 2004. There were 27 children, 14 (51.9%) were males and 13 (48.1%) were females (M:F=1.2:1), with ages ranging from 2 days to 5 years (median 5 months). Majority (84.6%) of the patients were below 1 year. The head and neck region was the most frequent site of involvement. There were three cases of lymphangioma circumscriptum. Six (54.5%) of the 11 children with cervical CL presented with complications including infection in 4, respiratory obstruction in 3, ulcerated lesion in 1 and intracystic hemorrhage with rapid increase in cyst size in 1. Twenty-three children had either surgical excision or marsupialization. The main complications were wound infections and respiratory obstructions, which led to five deaths. Six children had recurrences, some of which occurred at sites which were normal at the initial or previous excision. The mortality rate was high (34.8%), mainly due to respiratory obstruction and asphyxia in the head and neck lesions. Head and neck region was the most commonly involved site by CL. The management of CL at this site is associated with significant morbidity and a high rate of mortality.

* Splenic lymphangioma is a rare malformation of the splenic lymphatic channels, mostly seen in children. It is characterized by the presence of cysts, resulting from increases in the size and number of thin-walled lymphatic vessels that are abnormally interconnected and dilated. The condition may be restricted to the spleen, but in most cases it involves multiple organs (systemic lymphangiomatosis). The clinical picture is variable; small lesions are often incidentally detected through imaging studies, while larger lesions can result in compression of organs, causing pain or rupture even after minor trauma. Therefore, splenic lymphangiomas should be considered in the differential diagnosis of splenomegaly or left upper quadrant pain even among adults and should be immediately treated with splenectomy; delay in the therapeutic intervention can lead to life-threatening complications. (Arch Pathol Lab Med. 2015; 139:278-282; doi: 10.5858/arpa.2013-0656-RS), Lymphangiomas are benign malformations of the lymphatic system, usually found in the neck (75%) and axilla (20%) (1) and less commonly encountered in the orbit, mediastinum, adrenal gland, kidney, bone, [...]
