This report deals with the follow-up diagnostic evaluation of 18 patients previously treated for adrenal cortical carcinoma. The role of computed tomography is emphasized. Nine patients had adrenalectomy and the other 9 had adrenalectomy and ipsilateral nephrectomy. The left kidney and adrenal were removed in 8 patients. The patients were evaluated for 2-59 months with an average follow-up of 16 months. Of the 13 patients (72%) who had recurrent or metastatic disease, 8 experienced local recurrence in the adrenal fossa, 2 of whom had associated renal involvement. The recurrence was seen in 5 patients in the left and in 3 patients in the right side. Metastases occurred in the lung (7 patients), liver (3 patients), peritoneum (2 patients), paraaortic lymph nodes (3 patients), and bone (1 patient). At the time of the discovery of recurrence or metastases, 5 patients presented with lung metastases found on chest x-rays, 3 had recurrent Cushing's syndrome or hypertension, 3 had abdominal pain, 1 had weight loss, and 1 was asymptomatic.

Nineteen patients with fungal splenic abscesses included 16 with leukemia, one drug user, one patient with Cushing's syndrome, and one without predisposing causes. Fifteen had persistent fever; six had esophageal or mucocutaneous candidiasis. Abdominal pain occurred in seven patients, splenomegaly occurred in six, and left abdominal mass occurred in one. Three chest x-ray films showed left pleural effusions; two had elevated left hemidiaphragms, two had left-sided infiltrates, and one was normal. Sixteen of 17 technetium Tc 99m sulfur colloid scans were abnormal, as were 15 gallium citrate Ga 67 scans. Two computed tomographic studies revealed splenic defects. Candida was the cause in 15 cases, Aspergillus was the cause in three cases, and Blastomyces dermatitidis was the cause in one case. Sixteen patients underwent splenectomy, 12 receiving postoperative antifungal therapy. Fifteen survived regardless of underlying disease or hepatic microabscesses.

Information about epidemiology, natural history and prognostic factors of adrenocortical carcinoma in Italy is extremely scarce. We report here 35 patients of adult age who were referred to our institution in the last two decades. Nine patients had non functioning, and 26 had functioning tumors. In non-functional tumors initial symptoms were abdominal pain in 90% of cases, fever, weakness, malaise, weight loss in 30%. Only one patient was asymptomatic. Of patients with functioning tumors, 18 presented with Cushing's syndrome, 6 with Cushing's syndrome and virilization, 1 with Cushing's syndrome and feminilization and 1 with hyperaldosteronism. Twenty-two of all cases (63%) had metastases at diagnosis; most frequent sites were lung, liver and distant lymph nodes. The results of tumor staging, according to MacFarlane system, were: stage I, 1 patient (3%); stage II, 10 patients (28%); stage III-IV, 24 patients (69%). Twenty-six out of 35 patients underwent removal of the mass with complete adrenalectomy. Twelve patients received mitotane alone; 8 mitotane and chemotherapy; 5 chemotherapy alone; 2 radiotherapy associated with mitotane or chemotherapy; 1 anthalgic radiotherapy. Survival time ranged from 1 to 108 months. One-year survival rate was 60%, and 5-year survival rate was 10%. Lower survival rate compared with that reported from other countries is probably related to the referring of patients at very advanced stages of disease. Early recognition and referral, in addition to optimization of therapeutic protocols by multicenter studies, may improve prognostic aspects.

In order to evaluate the utility of laparoscopic adrenalectomy for Cushing's syndrome, the results of 6 laparoscopic adrenalectomies for Cushing's syndrome were compared with those of 34 other laparoscopic adrenalectomies, consisting of 7 pre-Cushing's syndromes, 13 primary aldosteronisms, and 14 non-functioning adrenal tumors. The results were also compared with 5 open adrenalectomies for Cushing's syndrome. The results of the laparoscopic adrenalectomies for Cushing's syndrome were as follows: the mean operating time was 216 +/- 46 min, and the mean estimated blood loss was 180 +/- 194 ml. From the third patient, an ultrasonic surgical system was used and the estimated blood loss decreased significantly. The ultrasonic surgical system, together with a more experienced surgical technique, also cut down the operating times. During surgical intervention, 2 complications occurred; a hemorrhage of more than 500 ml in one patient, and splenic injury in another, which was treated by compression. Postoperative complications occurred in 2 patients; paralytic ileus in one, and abdominal pain due to the pneumoperitoneum in the other. All patients except 2 patients with vertebral fracture began oral intake and ambulation 1 to 4 days postoperatively, and resumed normal daily activity on postoperative day 5 to 7. Compared with the laparoscopic adrenalectomies for the other adrenal tumors, the operating time and estimated blood loss in the Cushing's syndrome patients was not substantially different, though postoperative recovery was slightly longer. When compared with the open adrenalectomies, the operating time was longer, but the postoperative recovery period was significantly shorter. We conclude that with careful surgical intervention, experience of technique, and the introduction of proper equipment, a laparoscopic adrenalectomy for Cushing's syndrome can be performed as less-invasively as a laparoscopic adrenalectomy is for the other adrenal tumors. Furthermore, our findings suggest that laparoscopic adrenalectomy for Cushing's syndrome is likelier to have better postoperative results than conventional procedures, including a more rapid recovery to normal daily activity.

A 43-year-old female patient underwent abdominal ultrasonography and CT scan because of uncharacteristic abdominal pain. A 3-cm homogeneous adrenal tumor was diagnosed. The endocrine tests revealed an adrenal preclinical Cushing's syndrome (PCS). Due to the latent hormone excess we decided to operate on the adrenal tumor. Since the tumor was small, laparoscopic adrenalectomy was performed. Histological evaluation showed an adrenocortical tumor of undetermined nature. Four months later the patient presented with a metastasizing cortisol- and androgen-producing adrenocortical carcinoma (ACC). After pretreatment with ketoconazole to suppress the biosynthesis of adrenal steroids under substitution with hydrocortisone, we reduced the tumor load by surgery. Postoperatively we continued ketoconazole and started o, p'-dichlorodiphenyldichloroethane as well as chemotherapy with doxorubicin and suramin. However, the patient died from ACC 7 months after adrenalectomy. It is known from several reports that PCS may persist clinically silently or may progress to full-blown Cushing's syndrome. This is the first time a malignant course of PCS is described. Independent of the initial therapeutic strategy of PCS, i. e. surgery or regular follow-up visits, we must be aware that also relatively small adrenal tumors can harbor malignancy.

Adrenal cortical carcinoma (ACC) is a rare neoplasm that affects all age groups, with a bimodal peak of incidence, in young individuals in the first decade or two of life and in older subjects in the fifth to seventh decades. It may be clinically "functional" with Cushing's syndrome, virilization, or feminization, or it may be "nonfunctional." We report on the case of a 42-yr-old woman who complained of abdominal pain and a large adrenal tumor measuring 20 cm in size. No endocrine symptoms were observed. Laboratory tests showed increased levels of adrenocorticotropic hormone (ACTH), serum cortisol, and urinary free cortisol. Cytohistologic features were typical of ACC. A striking presence of hyaline cytoplasmatic globules was seen in cytologic smears and histologically, being immunoreactive for vimentin, consistent with an intracellular store of intermediate filaments. The tumor showed high proliferative activity (40%) with Ki-67 and negativity for p53, cerbB2, and bcl-2. Although hyaline globules are more frequent in pheochromocytomas and other neoplasms, they may also be present in ACC. These globules may be observed in cytologic smears. Also, the identification and immunohistochemical characterization of these hyaline globules in metastases may be useful in determining the origin of primary occult tumors. Diagn. Cytopathol. 1999;21:394-397.

RU-486's primary use as an abortifacient stirs controversy in the US. Changes in US policy have opened the door for RU-486 to be made available for research. The Population Council plans on conducting a multicenter clinical trial of RU-486 involving at least 2000 women. This is the first step to obtaining possible approval from the Food and Drug Administration. RU-486 alone has an effectiveness rate of inducing abortion between 80 and 90%. When taken 36 to 48 hours before a prostaglandin (PG) analogue, the rate climbs to about 95%. Possible side effects of RU-486 and the analogue are bleeding, abdominal pain, and cardiovascular problems (rare). More than 100,000 women in France have undergone the RU-486/PG analogue regimen. RU-486 also has contraceptive qualities. If taken every day during the week before ovulation, it prevents ovulation. 12 days of RU-486 administration followed by 10 days of administration of a synthetic progestin also suppresses ovulation. Taking RU-486 during the last 10 to 12 days of the menstrual cycle alters the endometrium, thereby preventing implantation. A single dose of RU-486 during the late luteal phase is about 80% effective at bringing on menses. The aforementioned effects of Ru-486 demonstrate that it may be an effective postcoital contraceptive. Besides, RU-486 has fewer side effects than other postcoital contraceptive regimens. Further, RU-486 softens and dilates the cervix, thus it can be used to induce labor and ease delivery. Evidence suggests that RU-486 may be used to treat hormone-dependent breast tumors, Cushing's syndrome, meningiomas, and endometriosis.

We reported the outcomes of computed tomography (CT)-guided percutaneous acetic acid injection therapy for functioning adrenocortical adenomas. With the patient in a prone position, the puncture needle was inserted vertically downward into the adenoma with frequent CT scanning. After confirmation by pilot injection with contrast medium, a small aliquot of 40-50% acetic acid was injected and repeated. Between 1997 and 2002, 18 sessions of CT-guided injection therapy, including one session of ethanol injection, were performed on 10 patients (five patients with primary aldosteronism and five patients with Cushing's or subclinical Cushing's syndrome) without any complications except transient upper abdominal pain during the acetic acid injection. The follow-up period ranged from 5-69 months. The treatment resulted in almost an extirpation of the adrenocortical hyperfunction in seven patients after one or two sessions. CT-guided percutaneous acetic acid injection might be a simple, cost-effective, and far less invasive treatment for small functioning adrenocortical adenomas.

We present a 54-yr-old woman with ectopic corticotropin syndrome caused by a neuroendocrine tumor of the pancreas. At initial presentation, the patient suffered from diarrhea, heartburn, and nonspecific abdominal pain. There was no evidence of Cushing's syndrome. A neuroendocrine tumor in the head of the pancreas with metastases into peripancreatic lymph nodes was diagnosed and completely resected. Fourteen months later, abdominal computed tomography and scintigraphy with (111)In-labeled octreotide suggested relapse of the tumor. The patient again had no evidence of Cushing's syndrome. A second in toto tumor resection was performed. Another 8 months later, the patient developed forgetfulness, depressive episodes, muscle weakness, new-onset hypertension, hypokalemia, plethora, diabetes mellitus, polyuria, and weight loss. Endocrine testing suggested a source of ectopic ACTH production. An octreotide scan showed an intense uptake ventromedial of the left kidney, an area that showed a mass lateral of the superior mesenteric artery on abdominal magnetic resonance imaging. A complete pancreatectomy with splenectomy and left-sided adrenalectomy were performed. At this second relapse, this neuroendocrine tumor clinically had changed its hormonal profile. Immunohistochemically, in contrast to primary tumor and first relapse, we found strong immunostaining for ACTH in tumor cells of the second relapse and a MIB-1 index greater than 20%. To our knowledge, this is the first report describing a pancreatic neuroendocrine tumor that started to secrete ACTH de novo at the time of the second relapse after two former complete tumor resections. This case underscores the pluripotency of neuroendocrine tumor cells and the importance of keeping in mind a possible shift in hormone production during tumor evolution and progression.

A 38-year-old woman with history of prior adrenalectomy for Cushing's syndrome presented with intermittent right lower quadrant (RLQ) abdominal pain, nausea, bloating, and non-bloody diarrhea for 2 months. Symptoms were not related to her menstrual periods. Examination revealed only an ill-defined mass in the RLQ. Investigations for infectious causes, inflammatory bowel disease, and carcinoid tumor were negative. Computed tomography (CT) demonstrated a terminal ileal mass with mesenteric stranding and dilatation of the proximal bowel. At laparotomy, a fibrotic, terminal ileal mass with matted adhesions involving the mesentery and retroperitoneum was resected. Histopathological examination identified multiple foci of endometriosis extending from the serosal surface into the mucosa of the terminal ileum. Immunostaining revealed E- and P-cadherin, but not N-cadherin immuno-positivity. Mucosal involvement without cyclical menstrual symptoms and intestinal obstruction is an unusual presentation of intestinal endometriosis. Although the mechanism of endometriosis is not clear, the role of cell adhesion molecules such as cadherins has received attention. Increased expression of E- and P-cadherin and decreased N-cadherin expression in our patient demonstrates differential expression of these cadherins in endometriotic tissue. Future studies may investigate patterns of differential expression of these cadherins in a series of cases to elucidate the mechanisms of migration of endometriotic tissue.
