Brooke-Spiegler Syndrome Quyn Sherrod, MD; Miguel Gutierrez, MD; Keith Carlson, MD UCLA/WLA VA Division of Dermatology David Geffen School of Medicine Los Angeles, California
History • 39 year-old, healthy, Caucasian male • Multiple lesions on face and scalp beginning at 10 years old • Nonpainful, nonpruritic • Previous paranasal biopsy consistent with trichoepithelioma • Mother with similar presentation
Brooke-Spiegler Syndrome • Uncommon syndrome with autosomal dominant inheritance pattern • Variable expression and penetrance • More severe phenotype in women • Mutiple cutaneous adnexal neoplasms • Cylindromas, spiradenomas, trichepitheliomas on head and neck
Clinical Presentation • Begins during second or third decade • Cylindromas, spiradenomas on scalp • ‘Turban tumors’ when numerous • Trichoepitheliomas more common on face • Progressive increase in size and number
Genetics • Autosomal dominant mutation affecting epidermal appendages • CYLD gene on chromosome 16q12-q13 • CYLD functions as a tumor suppresor • CYLD inhibits NF-κB transcription factor in the TNF-α signaling pathway, regulating cell growth
Differential Diagnosis • Familial cylindromatosis • Multiple familial trichoepithelioma • Rombo syndrome • Vermicular atrophoderma - Milia • Basal cell carcinomas - Hypotrichosis • Peripheral vasodilation/cyanosis - Trichoepitheliomas • Bazex syndrome • Follicular atrophoderma - Hypotrichosis • Basal cell carcinomas - Trichoepitheliomas • Hypohidrosis
Prognosis • Psychologic impact due to physical disfigurement • Rare malignant transformation of trichoepitheliomas into basal cell carcinomas • -Low metastatic potential • Rare malignant transformation of cylindromas and spiradenomas • -Local infiltration and distant metastases reported • Increased risk for salivary and parotid gland adenomas and adenocarcinomas
Treatment • Excision • Dermabrasion • Electrodessication • Cryotherapy • Radiotherapy • Laser- Argon, erbium:Yag, CO2 • Medical therapy with sodium salicylate and prostaglandin A1 is under investigation • -Inhibit NF-κB activiation • Monitor for clinical signs of malignant transformation
