RATIONALE: Presenting a rare case report of a giant multilobular lipoma in submandibular and submental spaces of anterior and lateral aspect of neck. PATIENT'S CONCERNS: The patient's main concern was persistent diffuse swelling in right lower face and neck region for 5–6 years. DIAGNOSIS: The lesion was diagnosed as multiple septate lipoma measuring 11.5 cm × 10.5 cm × 6.5 cm involving submandibular region and anterior triangle of the right neck following fine-needle aspiration cytology and radiological imaging. TREATMENT: Extraorally complete surgical excision was carried out through submandibular approach under general anesthesia. OUTCOMES: The patient's postoperative recovery was uneventful. The patient was followed up on a monthly basis for 6 months. No recurrence was observed. The patient was satisfied with the treatment. LESSONS: Lipomas should be considered as a rare differential diagnosis for anterior neck swelling. Biopsy is not necessary to confirm the diagnosis. Surgical excision remains the mainstay of treatment following final diagnosis through imaging modalities.
