Mutations in the fibroblast growth factor-receptor gene 2 (FGFR2) gene have been implicated in numerous diseases, including nevus comedonicus (NC) and naevoid acne that have somatic missense mutations in FGFR2 in the affected tissue. A patient presented in our department with unusual, innumerable large comedones throughout his back reminiscient of NC, as well as multifocal hidradenitis suppurativa and acne. Topical and systemic treatments were unsuccessful. Whole exome sequencing of blood-derived DNA detected a germline mutation in FGFR2 that was predicted to be damaging. This could explain the multifocal and severe nature of the disease. We suggest screening other, phenotypically similar patients for FGFR2 mutations. Our findings, once confirmed independently, could indicate that therapeutic modulation of FGFR signaling in the acne tetrad could be effective.
