Lumps and bumps

A lipoma is a soft benign tumour of adipose tissue. Lipomas usually occur singly, but may be multiple. They are commonly subcutaneous, but can be intramuscular. Lipomas are normally painless. If the tumour is tender, then it is more likely to be an angiolipoma. Rarely, liposarcomatous change can occur in a benign lipoma. There is a higher index of suspicion for malignant change if the lesion is large, rapidly growing or painful.

Our patient showed significant fatty overgrowth of the lesion, and the possibility of angiolipoma was considered. However, angiolipoma is often presented as multiple subcutaneous nodules of mature fat with a variable amount of capillary vessels without larger vessels histologically.11 IMH can be classified histologically based on the vessel size of the predominant vessels, including small vessels, large vessels and mixed types.12 Our patient was diagnosed with a mixed type of IMH involving the eyelid, and both clinical and radiological features of the initial MRI were compatible with capillary hemangioma. In comparison to infantile capillary haemangioma, which usually regresses with or without treatment,13 our patient’s upper eyelid mass persisted and responded poorly to intralesional steroid injections and required debulking surgery. Kim et al.6 reported a case of IMH involving the Muller muscle who showed no response to oral corticosteroid and eventually required surgical debulking with no sign of recurrence 3 months after the procedure.

Lipomas are common benign soft tissue tumors composed of mature white adipocytes. Lipoma, along with angiolipoma, spindle cell lipoma, pleomorphic lipoma, hibernoma, chondroid lipoma and lipoblastoma are categorized as benign lipomatous tumors [1]. Based on the depth of lesion, lipomas can be classified into superficial and deep lipomas. Superficial lipomas are typically asymptomatic and frequently found in the upper back, neck, shoulder and abdomen. Approximately 5–8% of lipomas present as lipomatosis, which lesions are microscopically indistinguishable from solitary lesion.
