[Pulmonary epidermoid carcinoma in a 22-year-old patient with multiple cutaneous metastasis].

The authors present one clinical case of lung epidermoid carcinoma with several concurrent features which are uncommon in relation to this type of neoplasia. Consequently, the age of the patient (22), the lack of known risk factors, the histologic type (little differentiated squamous) and an aggressive biologic behaviour of the tumour, preceded of multiple cutaneous metastasis, are circumstances that make this clinical case exceptional. The more significative aspects present at lung carcinoma included in this age group respect to others are analyzed.

Atypical carcinoid of larynx: presentation with scalp metastases.

A case of atypical carcinoid tumour of the larynx in a 72-year-old woman is presented. The neoplasm was located in the supraglottic region and was first manifest by metastases to the scalp. The presence of amyloid-like material and calcitonin-positive cells were features that resembled medullary carcinoma of the thyroid. Clinically, it pursued an aggressive course that led to death 58 months after diagnosis. The literature is reviewed, particularly that regarding the differential diagnosis.

Meningioangiomatosis and oligodendroglioma in a 15-year-old boy.

A case of meningioangiomatosis occurring in a 15-year-old boy is reported. The patient did not show signs of neurofibromatosis on physical examination, and his medical history included only one previous episode of loss of consciousness, which was accompanied by a self-limited focal seizure. The lesion was associated with an oligodendroglioma and was incidentally discovered during the macroscopic sampling of the neurosurgical specimen. The literature relating to this uncommon entity is reviewed and discussed. To the best of our knowledge, the concurrence of meningioangiomatosis and oligodendroglioma has not been documented previously.

Small intestinal stromal tumour with skeinoid fibers. Immunohistochemical study of two cases with CD 34 expression.

The presence of the so-called "skeinoid fibers" in stromal tumours of the gastrointestinal tract is a rare event. The exact origin of this puzzling group of neoplasms still remains controversial. Despite all, the recognition of this histologic feature in routine practice is important for its presence seems to carry histogenetic implications. The authors report the histopathologic findings of two of such cases both occurring in the jejunum of a male aged 48 and a woman, 64. Their positivity with CD 34 antigen is enhanced, for this peculiar immunophenotype help to distinguish them from other stromal tumors in the small bowel. Additionally, the literature is reviewed and commented.

[Rothmund-Thomson syndrome and osteosarcoma].

BACKGROUND: The Rothmund-Thomson syndrome is a hereditary dermatosis frequently accompanied by less well-known non dermatologic features including osteogenic sarcoma. CASE REPORT: A girl developed the classical dermatologic features of the Rothmund-Thomson syndrome since the first months of life. When she was 6 years old, she suffered from painful limitation of motion of her left leg. X-rays, MNR imaging and bone scintigraphy showed typical features of osteosarcoma of the distal portion of the femur. Diagnosis was confirmed by histologic examination through open biopsy. The search for metastatic lesions was negative. The patient was given chemotherapy and the tumor was resected 45 days later followed by postoperative chemotherapy. CONCLUSION: About 12 similar cases of osteosarcoma have been reported in patients with the Rothmund-Thomson syndrome. A review of literature allows to recognize some peculiar features of such association.

Well differentiated neuroendocrine carcinoma of the breast. A case report.

A neuroendocrine breast carcinoma occurring in a 79 year-old woman is presented. The case presented typically as a single nodule in the upper and outer quadrant of her right breast and showed a pure histology consisting exclusively of organoid nests of well differentiated cells that mimicked those of carcinoid tumors of the lung. The literature is briefly reviewed and commented. In the light of this review, we conclude that the issue of carcinomas with neuroendocrine differentiation in breast pathology is controversial and its terminology somewhat debatable.

Basaloid-squamous cell carcinoma of the larynx and hypopharynx. A clinicopathologic study of 7 cases.

During a 16-year period (1974-1989), a retrospective review of 468 surgical specimens of laryngectomy yielded 7 cases (0.66%) of basaloid-squamous cell carcinoma. They were all males between 42 and 63 years of age. Four cases were supraglottic and one transglottic. The other two arose in the left pyriform sinus and vallecula, respectively. At diagnostic time, 4 cases were Stage III and 2 Stage IV, only one being Stage II. Glanz index of histologic malignancy was high (> 5) in most cases (6/7). Mitotic rate was also high (22-78 mitoses/10 HPF). Lymph node metastases were documented at diagnosis in 5 cases, 3 of them presenting with extracapsular extension. One case developed liver metastases. During the follow-up, lymph nodes of the neck were again metastasized in 4 cases, and stomal recurrence was present in another one. Death of disease was confirmed in 5 cases after 10 to 35 months of follow-up. Overall survival was 28.5% after 3 years.

[Hepatic disease associated with human immunodeficiency virus infection: anatomo-clinical study].

OBJECTIVE: To study the spectrum of liver disease in the infection by the human immunodeficiency virus (HIV) and to assess the usefulness and indications of liver biopsy. PATIENTS: Fifty eight HIV seropositive patients (48 intravenous drugs users) were prospectively studied by means percutaneous liver biopsy, because of hepatic biological alterations, hepatomegaly or fever of unknown origin. RESULTS: Chronic hepatitis was the most common diagnosis, which was found in up to 20 patients (34%) (12 had chronic active hepatitis). Most of them were caused by hepatitis C virus (90%). Hepatic granulomatosis was diagnosed in nine patients (15%), all of them among the subgroup of 19 patients (47%) studied because of fever of unknown origin. Granulomas were thought to be caused by mycobacteria in eight cases (seven tuberculosis, one Mycobacterium avium-intracellulare. Mycobacteria were isolated in culture in four patients whose histologic findings were inspecific. Other representative diagnosis were liver cirrhosis in eight patients, lymphoma in two, alcoholic hepatitis in one and candidiasic hepatitis in one. The diagnostic yield of liver biopsy was 79%. CONCLUSIONS: Liver biopsy is a useful method in the diagnosis of these patients, specially if they present with fever of unknown origin or hepatic biological alterations. In this study chronic active hepatitis was the most common finding, while hepatic granulomatosis was so in patients with fever of unknown origin.

Gliosarcoma. Case report with immunohistochemical study.

A typical case of gliosarcoma in a 74 year-old woman is reported. The exact origin of sarcomatous areas of this tumor has been a matter of debate. Our immunohistochemical findings, using a panel of antibodies (GFAP), vimentin, keratins, F-VIII related antigen, muscle specific actin, KP-1 and HMB-45), support its undifferentiated nature. The literature concerning this topic is reviewed and briefly discussed.

Extraskeletal myxoid chondrosarcoma. A clinicopathologic and immunohistochemical study of two cases.

Two extraskeletal myxoid chondrosarcomas arising on the left lower extremity of two women, aged 48 and 72 years, respectively, are reported. One case mimicked clinically an organized hematoma. By light microscopy, they showed a lobular architecture. Anastomosing cords of cells lying in a myxoid background were the histologic hallmark. Based on conventional criteria, they were classified as neoplasms of low (G1) and intermediate (G2) grade malignancy. Both cases were strongly positive for S-100 protein and vimentin. Follow-up confirmed the low aggressiveness of this entity.

A case of Whipple's disease presenting as supraclavicular lymphadenopathy. A case report.

A case of Whipple's disease occurring in a 63-year-old woman is reported. Cervical lymphadenopathy and vague constitutional symptoms were soon followed by diarrhea and weight loss. Supraclavicular lymph node exeresis suggested the initial diagnosis, which was confirmed by intestinal biopsy. The concurrence of cystic spaces, PAS-positive foamy histiocytes and epithelioid granulomas is considered by the authors to provide a useful histological clue in the diagnosis of lymph node involvement in Whipple's disease. Pathologists must be aware of such an un-conventional presentation of this rare entity and therefore include it within the differential diagnosis of cervical and/or axillary lymphadenopathies.

Localized fibrous tumor of the pleura. Report of two cases with immunohistochemical study.

The light microscopy and immunohistochemical findings of two new cases of localized fibrous tumor of the pleura are reported. Both cases remained asymptomatic. One of them was incidentally found in a 69 year-old male during a thoracotomy for adenocarcinoma of the lung. The other was discovered in a 51 year-old woman in the course of a routine chest X-ray. Bundles of tightly packed benign fibroblasts within a collagen-rich stroma were the histologic hallmark. Bizarre cells and prominent sclerosis were extensive features in the first case. Only vimentin showed diffuse positive immunostaining in proliferating cells. Our results support the fibroblastic origin proposed for this lesion.

[Acute severe hepatic insufficiency caused by carbamazepine].

Acute liver toxicity caused by carbamazepine is a well known though infrequent event. Severe toxicity with hepatocellular insufficiency is even more rare. A case is presented of a patient who suffered of partial epilepsy on treatment with valproate and carbamazepine, who was admitted because of severe acute liver insufficiency attributable to carbamazepine. He had started treatment with the latter drug two weeks earlier, when he developed fever, jaundice, rash and signs of encephalopathy in association with elevation in serum transaminases levels and a decrease in prothrombin index (24%). Discontinuation of both antiepileptic drugs, together with the usual supportive measures, was followed by a complete resolution. Valproate was restarted without complications. Liver biopsy suggested acute hepatitis of drug-related origin. Granulomas or steatosis were not found. The histologic picture together with the relation between carbamazepine administration and the development of hepatotoxicity allow us to dismiss valproate as the possible causal agent of this patient's disease. Therefore, we believe it was an acute hepatocellular failure secondary to carbamazepine.
