FRIEDRICH Department of Oral and Maxillofacial Surgery, Eppendorf University Hospital, University of Hamburg, Germany Abstract. This case report describes the diagnosis and Case Report therapy of a patient with a 40-year history of multiple potato-like tumours growing in the head and neck region. Patient. A seventy-five-year-old woman was referred to the The tumour proved to be a cylindroma, associated with Department of Oral and Maxillofacial Surgery from the calvarian defects. Further facial tumours were diagnosed as Department of Dermatology, Eppendorf University Hospital, trichoepitheliomas. This association of findings was for treatment of an extensive cylindroma of the entire scalp. pathognomonic for Brooke-Spiegler’s syndrome. Complete The patient first sought for medical advice in the University work-up of the resection specimen excluded any malignant Hospital 4 years previously but had refused any surgical transformation of the tumour. A long lasting history of treatment (Figure 1). On presentation, the patient was in cylindroma and evidence for bone destruction, not associated generally good condition. The primary reason the patient with a malignant transformation, is extremely rare in decided to seek surgical treatment was an ill-fit of her wig Brooke-Spiegler’s syndrome. (Figure 2). The patient’s medical history showed an early onset of the enlargement of the skin of her skull and the development Cylindroma is a slow growing, benign tumour of the skin (1), of potato-like tumours about 40 years earlier. At the same time, affecting preferentially the head and neck region, especially she noticed a growing baldness in the area of tumour growth the capillitium and forehead (2, 3). The term “turban tumour” and started wearing a wig. The patient could not provide is used to describe the topography of the tumour and its information about her family history because she and her sister pathognomonic size (4-10). A turban tumour can grow to an had been adopted as very small children and never knew their enormous size (covering the whole scalp) and cause severe parents.

Thus, the possibility of hereditary or sporadic be affected by cylindromas (11, 12), which may also occur tumour development could not be established. exclusively outside of the head and neck area (1, 13). To date, At the time of attendance, the tumour had grown circular there has been no report on bone destruction associated with around the capillitium, infiltrated both auricles, and further the occurrence of a turban tumour. Indeed, it is generally tumours of the head and neck area had grown on her chin and accepted that bone defects in a cylindroma are signs of neck.

The scalp was completely excised under general anaesthesia so that the tumour could be resected. The resection slices were 28 cm × 18 cm × 6 cm and 30 cm × 20 cm × 6 cm, respectively. The maximum diameter of single nodules was 8 cm. In this first operation, the bone was left intact in order to gain histological information of the tumour Figure 4.

A patient with a turban-like tumour was first reported by Surgical resection of the tumour masses with Ancell (17). The clinicopathological features of cylindroma reconfiguration of the auricle and outer meatus has were described in detail by Spiegler (3) and Brooke (5). The prompted acceptable results (7, 12). cylindroma of the skin arises from eccrine or apocrine glands To the Author’s best knowledge, there has been no prior (18). The tumour forms thick layers of collagen-rich report of a cylindroma of the head and neck region (turban extracellular matrix (11, 19, 20). tumour) where evidence was presented for multiple lesions The medical history of patients with cylindroma usually of the calvarium and definitive exclusion of malignant covers years or even decades of their life.

The solitary type is Acknowledgements usually of sporadic origin, whereas the multiple-lesion type is often a predominantly inherited disease (12).
