A Case Report on LUMBAR Syndrome in an Infant With Ulcerated Sacral Hemangioma and Spinal Dysraphism.

Infantile hemangiomas are the most common soft tissue tumors in infancy, most following a benign and predictable course. However, some hemangiomas, particularly those in the lower body, can indicate underlying syndromic anomalies, as seen in lower body hemangiomas and other cutaneous defects, urogenital anomalies, ulceration, myelopathy, bony deformities, anorectal malformations, arterial anomalies, and renal anomalies (LUMBAR) syndrome. This report presents the case of a term infant with a large superficial ulcerated sacral hemangioma and associated spinal dysraphism, including tethered cord, partial sacral agenesis, and intraspinal lipoma. The early multidisciplinary evaluation confirmed the diagnosis of LUMBAR syndrome, and the patient underwent surgical management of cutaneous discontinuities and initiated oral propranolol. Propranolol was effective in resolving the ulcerated component of the hemangioma. This case highlights the importance of recognizing lower body hemangiomas as markers for potential underlying anomalies, emphasizing the role of early diagnosis, comprehensive imaging, and multidisciplinary care in optimizing outcomes for this rare but complex syndrome.
