of pituitary carcinomas are non-functioning but PRL&#44; ACTH&#44; GH and TSH secreting carcinomas have also been described&#46; Regarding somatotroph carcinomas&#44; 11 patients have been reported since the beginning of the century<span class="elsevierStyleSup"> 1-9</span>&#46;

He was studied in another medical center in 1990 to investigate the cause of a confusional state and the diagnosis of acromegaly due to a GH secreting pituitary macroadenoma was made &#40;fig&#46; 1&#41;&#46; He was operated in 1990 by subfrontal way&#46; The postoperative magnetic resonance imaging &#40;MRI&#41; showed tumoral persistence because of the patient was irradiated with 50 Gy&#46; In 1993&#44; the patient complaint of loss of vision in the left eye and the MRI showed a very large tumour with suprasellar invasion and hydrocephalus&#46; Another adenomectomy by subfrontal way was then necessary to partially remove the tumour&#46; </p><p class="elsevierStylePara"><img src="1741.GIF" width="229" height="350"></img></p><p class="elsevierStylePara"> In 1994&#44; at the moment of the first visit to the hospital&#44; the hormonal values of the patient were GH 3&#46;7 &#181; g&#47;l and IGF-I 420 ng&#47;ml &#40;normal range &#60; 400 ng&#47;ml&#41; with abnormal suppression of GH &#40;GH &#62; 2 &#181; g&#47;l&#41; following an oral glucose load&#46; In August 1994&#44; the patient developed neurological alterations as loss of vision in the left eye&#44; disturbance of intellectual function and somnolence&#46; It was necessary another surgery because the MRI showed an important tumoral regrowth&#46; Three months after the craniotomy&#44; MRI showed an important cyst involving tumoral nodes in the left hemisphere and the patient underwent stereotaxic radiosurgery with a total dose of 1&#44;000 cGy &#40;fig&#46; 2&#41;&#46; Endocrine investigations revealed GH levels of 6 &#181; g&#47;l and IGF-I 708 ng&#47;ml&#46; The patient did not present GH paradoxical responses after infusion of TRH &#40;250 &#181; g i&#46;v&#46;&#41; or GnRH &#40;100 &#181; g i&#46;v&#46;&#41;&#46; Treatment with somatostatin analogues was then initiated &#40;lanreotide 0&#46;03 g i&#46;m&#46;&#47;28 days&#41; and after 3 months of therapy&#44; GH and IGF-I levels decreased to 2 &#181; g&#47;l and to 325 ng&#47;ml respectively&#44; and normal suppression of GH after an oral glucose load was observed&#46; The patient continued with the same treatment but in the sixth month of therapy an unexpected recurrence was observed&#46; In fact&#44; GH levels raised to 14 &#181; g&#47;l with IGF-I to 925 ng&#47;ml and the patient developed neurological alterations as progressive weakness in the lower limbs and abnormal gait&#46; MRI demonstrated a large tumoral mass in the anterolateral part of the frontal lobe and an enlargement of the posterior cyst &#40;fig&#46; 3&#41; and in October 1996&#44; the patient underwent his forth surgical procedure by subfrontal way&#46; The excision was nearly complete except for tumoral tissue around cavernous sinus&#46; Following surgery&#44; MRI scan of the brain revealed 4 tumoral deposits&#46; Three of them localised in the frontal lobe and the other one&#44; in the cavernous sinus&#46; Then&#44; the patient received near 1&#44;000 cGy in each deposit by stereotaxic radiosurgery&#46; Nowadays&#44; the patient follows periodic controls in order to detect another recurrence&#46; Endocrine investigations have shown normal levels of GH and IGF-I &#40;0&#46;5 &#181; g&#47;l and 314 ng&#47;ml&#44; respectively&#41; so the patient does not receive any medical treatment&#46; Last MRI&#44; performed after 1 year of the last adenomectomy&#44; shows tumoral nodes of approximately 1 cm of diameter around the cyst in the left frontal lobe&#46; He has also undergone a <span class="elsevierStyleSup">99</span>Tc octreotide scintiscanning that has not shown evidence of somatostatin receptors&#46; Gastrointestinal tract examination&#44; chest X-ray film&#44; gallium scintigram and abdominal ultrasonography have not revealed any metastatic lesion&#46; </p><p class="elsevierStylePara"><img src="1742.GIF" width="229" height="377"></img><img src="1743.GIF" width="229" height="377"></img></p><p class="elsevierStylePara"> Histological studies of the resected specimen from the last three craniotomies were similar&#44; showing high pleomorphism in cytoplasms and in nucleus&#46; The tumour was poorly vascularizated with diffuse arrangement of well-defined polygonal cells&#46; Cellular cytoplasms were large with a high number of acidophilic granules&#46; Mitotic activity was increased in some areas of the tumoral pieces&#46; There were not signs of vascular invasion&#46; No cells were obtained from the liquid in the cyst&#46; </p><p class="elsevierStylePara"> In all the tumoral pieces&#44; immunocytochemistry staining demonstrated presence of positive cells for GH and absence for the rest of pituitary hormones&#46; As it has been proposed that indices of cellular proliferation be increased in invasive adenomas an often high in carcinomas<span class="elsevierStyleSup">10</span>&#44; the expression of Ki67 antigen was evaluated&#46; This antigen is a proliferation marker selectively expressed during G1&#44; S1&#44; G2 and M phases of the cell cycle&#46; The presence of p53 tumour suppressor gene was also studied because is thought to play a role in the development or evolution of adenohypophysial neoplasms&#46; In 1993&#44; there were not positive cells for these markers but surgical pieces of 1995 and 1996 showed positivity for both of them&#46; In 1995&#44; the proliferating cell nuclear Ki67 antigen was present in 2&#46;0&#37; of cells and p53 in 1&#46;6&#37; of cells&#46; In 1996&#44; Ki67 was present in 1&#46;5&#37; of cells and p53 in 1&#46;0&#37; of cells&#46; </p><p class="elsevierStylePara"><span class="elsevierStyleBold">DISCUSSION</span></p><p class="elsevierStylePara"> Earlier literature considered locally aggressive tumours to be malignant&#59; however&#44; current classification describes these lesions as &#34;invasive adenomas&#34;&#46; Pituitary carcinomas are distinctly uncommon and diagnosis is normally made when metastasis appear in a patient with a pituitary adenoma but the period between the onset of the primary lesion and distant metastasis tends to be long &#40;4 to 19 years&#41;<span class="elsevierStyleSup">3&#44;10</span>&#46; Therefore&#44; defining the difference between invasive pituitary adenoma and pituitary carcinoma only when metastasis appears could be a matter of time&#46; In fact&#44; the clinical course of most reported cases of pituitary adenocarcinoma has been one of progressive intracranial expansion of a pituitary neoplasm with metastatic lesions discovered post-mortem<span class="elsevierStyleSup">5</span>&#46; As in the case described before&#44; in all pituitary carcinomas producing GH&#44; the patients had previously diagnosed pituitary tumours with features of acromegaly&#46; All primary tumours were large&#44; with suprasellar extension&#44; requiring a transcranial surgical approach&#46; Primary resection was incomplete in all cases&#44; with residual tissue remaining in the cavernous sinus and&#47;or adherent to the frontal lobes&#46; As a result&#44; all patients also received treatment with radiotherapy&#46; In spite of the diagnosis of malignancy in pituitary lesions being usually made when metastasis appear&#44; the aggressive behaviour of the pituitary lesion in this patient allows to suspect and adenoma to carcinoma transformation&#46; In fact&#44; 3 tumoral recurrences despite surgery&#44; radiotherapy and medical treatment are unusual in other GH pituitary adenomas&#46; With regard to hormonal activity&#44; GH levels seemed to be under-control after three months of therapy with somatostatin analogues but an unexpected recurrence induced an important raise of the hormonal levels&#46; This agrees with previous observations that tumour suppression may not ocurr with somatostatin analogues&#46; Moreover&#44; this patient presented a negative <span class="elsevierStyleSup">99</span>Tc octreotide scintiscanning after the last craniotomy&#46; </p><p class="elsevierStylePara"> Histopathological criteria are also unhelpful in determining the malignant potential of pituitary tumours because pleomorphism&#44; abundant nuclei and increased mitotic activity are commonly seen in benign pituitary adenomas and some tumours with metastasis have very regular histology&#46; However&#44; it has been hypothesed that the presence of proliferation indices as well as p53 immunoreactivity suggests the diagnosis of pituitary carcinoma and appears to be of prognostic significance<span class="elsevierStyleSup">11</span>&#46; In fact&#44; an alternative definition of pituitary carcinoma based on increased mitotic activity&#44; high proliferation indices and the presence of p53 staining has been proposed<span class="elsevierStyleSup">10</span>&#46; In the case described before&#44; neither Ki67 nor p53 were expressed in 1993 but became present in subsequent surgical pieces&#46; A clear correlation between positivity of these indices and tumoral malignancy has not been demonstrated but the presence of these indices can indicate a more aggressive behaviour of the tumour&#46; </p><p class="elsevierStylePara"> The definition of pituitary carcinoma requires the demostration of metastasis&#59; however the presence of an aggressive behaviour as in the case described before suggests the diagnosis and appear to be of prognostic significance&#46; In order to confirm this hypothesis it would be necessary to survey closely the clinical evolution of this patient and other cases with similar behaviour&#46; </p>"
