Efficacy of bleomycin for non-operative treatment of cervical lymphangioma in University of Ilorin Teaching Hospital, Nigeria

ABSTRACT

Background: Lymphangiomas are the developmental defects of the lymphatic channels, and they are most commonly found in the head and neck regions. Late presentation, rejection of surgery, and traditional scarification result in fatal complications. Surgical excision often thought to give immediate relief and aesthetic results is associated with damage to contiguous structures and recurrence, hence, the need for less invasive treatment modality. Objective: To assess the effectiveness of bleomycin sclerotherapy of cervical lymphangiomas. Materials and Methods: This is a prospective study of patients with cervical lymphangioma treated with sclerosant injection between January 2008 and December 2016. Preinjection ultrasound scan and initial ultrasound-guided aspiration of the fluid in the swelling (which many times is multiloculated) using a 20G cannula into a 10 ml syringe were performed. The cannula tip is retained in the space and intralesional injection of double-diluted bleomycin 0.5 i.u./kg body weight was given as outpatient at 2­4-weekly interval. Postinjection events were documented. The clinical assessment of the pre- and postinjection of sclerosant was performed. Result: A total of 23 patients were recruited, and six were females and 17 were males. All swellings were noticed at birth but median time at presentation was 17 days. All patients but one (95.8%) had complete clinical resolution after 1­4 courses of sclerotherapy for 4­16 weeks. Only one patient had residual nodule that required surgical excision. Redundant skin and hyperpigmentation from skin wrinkle were the early effects noticed in three patients; however, these were cosmetically acceptable to the parents. No recurrence was recorded. Conclusion: The treatment of cervical lymphangiomas with intralesional bleomycin injection is shown to be effective. It is safe and associated with no complication. This treatment modality and outcome was found to be acceptable to the parents of these children
