title: Two unusual tumours of the gastrointestinal tract in a patient with tuberous sclerosis.
abstract: A 16 year old girl with an established diagnosis of tuberous sclerosis presented with a 1 year history of swelling of the left cheek. A 2 cm diameter tumour was excised which showed histological features of a solid variant of a minor salivary gland basal cell adenoma. One year later during laparotomy and excision of multiple renal angiomyolipomas, a 5 cm diameter subserosal tumour was found at the hepatic flexure of the colon. Examination of biopsy material revealed a leiomyoma. This case is presented to demonstrate two tumours that have not to the authors' knowledge been previously described in a young patient with tuberous sclerosis. Although the association may be coincidental, these tumours could represent two rare associations of tuberous sclerosis.
