Brooke-Spiegler Syndrome
Brooke-Spiegler Syndrome v Uncommon syndrome with autosomal dominant inheritance pattern v Variable expression and penetrance v More severe phenotype in women v Mutiple cutaneous adnexal neoplasms v Cylindromas, spiradenomas, trichepitheliomas on head and neck
Clinical Presentation v Begins during second or third decade v Cylindromas, spiradenomas on scalp v ‘Turban tumors’ when numerous v Trichoepitheliomas more common on face v Progressive increase in size and number
Genetics v Autosomal dominant mutation affecting epidermal appendages v CYLD gene on chromosome 16 q 12 -q 13 v CYLD functions as a tumor suppresor v CYLD inhibits NF-κB transcription factor in the TNF-α signaling pathway, regulating cell growth
Differential Diagnosis Familial cylindromatosis v Multiple familial trichoepithelioma v Rombo syndrome v – – – v Vermicular atrophoderma - Milia Basal cell carcinomas - Hypotrichosis Peripheral vasodilation/cyanosis - Trichoepitheliomas Bazex syndrome – – – Follicular atrophoderma Basal cell carcinomas Hypohidrosis - Hypotrichosis - Trichoepitheliomas
Prognosis v Psychologic impact due to physical disfigurement v Rare malignant transformation of trichoepitheliomas into basal cell carcinomas – -Low metastatic potential v Rare malignant transformation of cylindromas and spiradenomas – -Local infiltration and distant metastases reported v Increased risk for salivary and parotid gland adenomas and adenocarcinomas
Treatment v v v v Excision Dermabrasion Electrodessication Cryotherapy Radiotherapy Laser- Argon, erbium: Yag, CO 2 Medical therapy with sodium salicylate and prostaglandin A 1 is under investigation – -Inhibit NF-κB activiation v Monitor for clinical signs of malignant transformation
