Since the first description of the classic triad of adenoma sebaceum, epilepsy and mental retardation by Vogt, various manifestations have been added to the clinical picture of Bourneville-Pringle disease or tuberous sclerosis. Diagnosis, therapy and potential complications of the more frequent manifestations are summarized. Since even oligosymptomatic patients may develop dangerous complications, the importance of thorough examination is emphasized.

The authors describe three cases of familial acrocephalosyndactyly (ACS) in two boys (9 and 3 years of age) and in their 7.5-year old sister. In addition, irregularities in skull and limbs were found in the 46-year old father as well as in two other children, i.e., two girls, 14 and 4 years of age. The mother (46 years-old) and the remaining four 4 boys (12-, 9-, and 7-years-old), as well as the youngest child, a son, 1-year-old) did not show any deviations. The diagnosis of the Saethre-Chotzen syndrome in six members of one family was based on the finding of a typical skull deformation (oxybrachycephalia), low hairline, flattened nasofrontal angle, lateral deviation of the nasal septum, facial dysmorphy, prolapse of upper eyelids, antimongoloid placement of palpebral fissures, protruding eyes, hypertelorism, dysmorphy of auricles, imperfect hearing, highly arched palate, improper dentition, and characteristic skin syndactyly of hands and feet. In addition, deformed chest, weight and height deficiency, significant mental retardation, as well as, in the boys, true cryptorchidism were found. Radiological examination showed, in all affected members of the family, intensified digitate impressions within the whole fornix of the skull, large and deep sella turcica, underdeveloped frontal bone and upper jaw bone, untypical syndactyly of hands and feet, and the partial bifid of distal phalanges of the great toes, not described previously in the Saethre-Chotzen syndrome. In the differential diagnosis, other forms of ACS, i.e., Apert, Vogt, Pfeiffer, Summitt, and Herrmann-Opitz syndromes, were not found. Manifestation of the described symptoms transferred autosomally, dominantly, and with a similar degree of expression in 6 of 11 members of one family, leads us to think that they are the consequence of a fresh mutation revealed in the father.

Tuberous sclerosis (Bourneville-Pringle disease) is an genetic autosomal dominant disease, but in over 50% cases there are new spontaneous mutations. During this disease visceral hamartomas do tend to develop in various tissues. Earlier it was considered that in order to set a diagnosis the knowledge of Vogt's triade was required (angiofibroma, epilepsia, mental retardation). But new not typical forms occur, that do not contain all the above mentioned three elements. The phenomenon is connected with the appearance of a new mutations of the gene or with a variable gene penetrance. In these study case we present a 21-year old patient who shows the fully blown symptoms of Vogt's triad and her father who only has hypopigmented macules on his back.

Subependymal giant cell astrocytoma (SEGA) is usually associated with tuberous sclerosis (TS) and believed to originate from subependymal nodules. We report a rare case of SEGA in a patient lacking symptoms of TS. Radiological findings, including CT and MRI, were characteristic of SEGA, but the preoperative diagnosis was difficult due to the fact that no other features of TS were present. TS has been classically characterized by the clinical presence of Vogt's triad of seizure, facial angiofibroma and mental retardation, however, few cases present with all of these manifestations. In 1998, Roarch et al. proposed new clinical diagnostic criteria for the TS complex based on the clinical and radiographic features of TS. According to these criteria, our case is classified as a "possible" TS complex. There have been previous reports of SEGAs without any obvious features of TS, but it is still controversial as to whether these reports represent a forme fruste of TS. To determine a strict diagnosis of SEGA, additional genetic studies are needed. The possibility of SEGA should be considered whenever an intraventricular tumor near the foramen of Monro is found, regardless of other clinical features of TS.

Case Report. A nine-year-old patient with a diagnosis of tuberous sclerosis (with no pathological record) that showed calcifications at the brain level. Besides, the case showed the Vogt triad (epilepsy, mental retardation, and sebaceous adenoma). The patient clinically showed a volume increase of hard consistency, without suppuration and no sessile that included the following teeth 73, 74, and 75. Cone beam computed tomography (CBCT) was obtained, and it displayed a delimited unilocular lesion. After surgical excision, the histopathological report was desmoplastic fibroma (DF). It was observed that the patient had an aggressive recurrence of DF at four months after surgery treatment. Due to these clinical findings, resective osseous surgery and curettage were carried out. It is uncommon to find these two pathologies together (DF and tuberous sclerosis). Since DF is a benign pathology but very invasive and destructive, it is necessary a constant follow-up examination due to a high recurrence frequency.
