Cavernous Haemangioma of the Submandibular Triangle Eluding the Gland – A Case Report

Abstract

Abstract Rationale: Haemangiomas are benign vascular malformations. They are common neoplasms of infancy but seldom manifest at birth. Although common in the head & neck region, they are rare in the submandibular region. Despite being benign, surgical treatment is necessary if it causes significant functional or aesthetic compromise. Patient Concerns: The patient’s primary complaint was swelling in the submandibular region. Diagnosis: Initial examination and imaging studies were suggestive of sialolithiasis due to the presence of multiple calcifications. Ultrasonographic and magnetic resonance imaging were suggestive of haemangioma with multiple phleboliths. Treatment: Excisional biopsy was done without compromising the submandibular gland. A histopathological examination was done post-operatively to confirm the diagnosis. Outcomes: Post-operative recovery was uneventful and 6-month follow-up showed no recurrence. Take-away Lesson: This case highlights the importance of considering haemangioma in the differential diagnosis of submandibular region masses and emphasises the preservation of the submandibular gland when the extent of the lesion permits.
