Anisometric cell lipoma: Insight from a case series and review of the literature on adipocytic neoplasms in survivors of retinoblastoma suggest a role for RB1 loss and possible relationship to fat-predominant ( “fat-only”) spindle cell lipoma

The term “anisometric cell lipoma” (ACL) has been proposed recently by Evans for a lipoma variant characterized by striking variation in size and shape of adipocytes but little or no cytological atypia. One patient with multiple ACL had a history of retinoblastoma. The current study analyzed six patients with ACL (4 males and two females aged 34 to 87years; median, 58); all seen in consultation. Five patients presented with solitary and one with multiple subcutaneous masses measuring 5 to 9cm (median, 7.5cm).
