Cylindroma transforming into basal cell carcinoma in a patient with Brooke-Spiegler syndrome.

ABSTRACT: BACKGROUND:Brooke-Spiegler syndrome is a rare condition with a predisposition to develop cutaneous adnexal neoplasms, especially cylindromas, trichoepitheliomas and spiradenomas. Malignant transformation of cylindromas is rare. In such cases usually cylindrocarcinomas develop within these lesions. We present an unusual case of basal cell carcinoma developing within a preexisting cylindroma. MAIN OBSERVATIONS:58-year-old woman with a 30-year history of multiple dermal cylindromas extensively involving her scalp was referred for dermatological treatment. The patient reported that one of the long-lasting lesions, 5.5 cm in size, ulcerated within the foregoing few weeks. Histopathology confirmed cylindromas and basal cell carcinoma within the ulcerating tumor. Surgical excision of largest cylindroma tumors led to cosmetic and functional improvement. Magnetic resonance and computed tomography showed tumor infiltration into the skull lamina externa. Metastases were excluded by chest radiography and abdominal ultrasound examination. CONCLUSION:Patients with Brooke-Spiegler syndrome should be followed-up for malignant transformation of skin tumors to prevent deep penetration and possible metastases.

Project description:Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs), odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies). Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm) are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull) are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5-10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling). Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome). Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser ablation, photodynamic therapy and topical chemotherapy. Radiotherapy should be avoided. Vitamin A analogs may play a preventive role against development of new BCCs. Life expectancy in NBCCS is not significantly altered but morbidity from complications can be substantial. Regular follow-up by a multi-specialist team (dermatologist, neurologist and odontologist) should be offered. Patients with NBCCS should strictly avoid an excessive sun exposure.
