Angiomyofibroblastoma (AMF) is a rare, slow-growing and usually asymptomatic benign mesenchymal tumor that pre-dominantly arises in the genital tract, vulva, perineum and pelvis in women, while angiomyofibroblastoma-like (AMF-like) tumors develop in the inguinal region, scrotum and perineum in men(1). They usually arise in the 5th–6th decade of life. This type of tumor is derived from perivascular stem cells and has capacity of lipoid and myofibroblastic differentiation. AMF-like

Angiomyolipoma (AML) is a benign tumor consisting of abnormal vessels, smooth muscles, and fatty tissue. It accounts for 0.3–3% of all renal masses and is the most common type of benign kidney tumors(1). About 80% of AMLs present as isolated entities(2), but they are also frequently associated with tuberous sclerosis complex (TSC)(3). AML is radiologically classified into three subtypes according to the amount of fat which is quantified by CT or MRI: fat-rich AML, fat-poor AML, and

As a consequence, they can be associated with immune-related adverse events (irAEs) due to loss of self-tolerance, including rare cases of immune-related cytopenias.
