Nevus Sebaceous of Jadasson (SNJ) has been reported with various coexisting benign and rarely with malignant neoplasms. We present a case of SNJ with five benign epidermal and adnexal neoplasms, some of them with unusual features. Histologically, all of the typical findings of SNJ appear in our case along with a) a focal area of basaloid proliferation (tumour of the follicular infundibulum), b) more desmoplastic area with features of desmoplastic trichilemmoma and c) a nodular area with cytological features of trichilemmoma. In addition d) apocrine adenoma and e) syringocystadenoma papilliferum were present in adjacent areas. There were no features of malignancy. In summary, we report a complex case of SNJ with five unusual and concurrent neoplastic variants.
