Abstract
BACKGROUND
Angiolipoma is a rare benign tumor composed of mature adipocytes and proliferative capillary networks, most frequently found in the extremities. Occurrence in the nasal region, particularly at the alar base, is exceedingly rare, with no prior cases documented in the English-language literature.
CASE SUMMARY
A 59-year-old Korean lady presented with painless, progressive swelling of the right nostril of the right nasal alar base. Radiologic evaluation revealed a well-circumscribed, enhancing 10 mm mass without bony erosion or intranasal extension. The lesion was successfully excised via a local alar sulcus approach under local anesthesia. Histopathological examination revealed a well-encapsulated lesion composed of mature adipose tissue interspersed with variably sized blood vessels. Immunohistochemical staining confirmed vascular smooth muscle positivity for α-smooth muscle actin within the vascular walls, consistent with the diagnosis of angiolipoma. No atypia, mitosis, or infiltration was identified. The surgical course was uneventful, with cosmetic and functional results, with no evidence of recurrence at follow-up.
CONCLUSION
This is the first published case to widen the morphological spectrum of nasal angiolipomas and underscores the relevance of including angiolipoma in the differential diagnosis of vascular-appearing nasal tumors. Complete surgical excision provides good cosmetic and functional benefits with a low chance of recurrence.
Core Tip: This is the first published case to widen the morphological spectrum of nasal angiolipomas, particularly at the nasal alar base and underscores the relevance of including angiolipoma in the differential diagnosis of vascular-appearing nasal tumors. Complete surgical excision provides good cosmetic and functional benefits with a low chance of recurrence. It also provides an overview of the surgical technique for reconstruction of alar base defects. This case adds valuable insight to the literature and encourages heightened clinical suspicion for accurate diagnosis and optimal surgical management.
