[Simple thyroid cyst].

Simple or true thyroid cysts are very rare. We only have found one case in which colorless and acellular transparent fluid has been found by means of the fine needle aspiration puncture (FNAP). We report the case of a 33 year old female who first presented with a rapidly growing thyroid nodule. The thyroid scintigraphy revealed the existence of a cold nodule and the ultrasonography showed a lesion having a cystic appearance. The FNAP was performed and was both diagnostic and therapeutic in this case.

[Pulmonary inflammatory pseudotumor. Its diagnosis by fine-needle aspiration puncture].

Cytological characteristics are reported in the case of a 20-years-old male with pulmonary inflammatory pseudotumor (PIP) diagnosed by fine-needle aspiration (FNA) and later confirmed histologically. The patient presented a large tumor on the lower lobe of the right lung with hemoptysis, hemothorax and secondary acute anemia. The clinical-pathological profile of PIP are reviewed, along with diagnostic problems arising from the morpho-structural characteristics of the disease.

[The diagnostic value of liver aspiration puncture with echographic control].

OBJECTIVE: To correlate liver fine needle aspiration (FNA) diagnosis with histopathological diagnosis and clinical evolution. DESIGN: Retrospective analysis of liver FNA validity, evaluating sensitivity, specificity and predictive value of the method in correlation with the clinical evolution and biopsy results. RESULTS: Malignancy was diagnosed in 46 cases (20 hepatocarcinomas and 26 liver metastases), and benign lesions in 24 patients. Ten additional cases were excluded on the grounds of insufficient material or the impossibility of establishing clinico-histological correlation. There were 6 false-negatives and one false-positive. The overall accuracy of the method was 90% with a sensitivity of 88.2% and specificity of 94%. The positive and negative predictive values of the method were 97.8 and 75%, respectively. CONCLUSIONS: Liver FNA is efficient in cases of suspected liver tumoration. The technique proved particularly useful in the present series in diagnosing liver metastases, often allowing the establishing of tumor origin.

[Angio-invasive disseminated aspergillosis: autopsy diagnosis in leukemic patients].

We report on two patients with acute lymphoblastic leukemia in induction chemotherapy, who developed a sepsis which led, in both cases, to death following the appearance of neurological symptoms suggesting CNS affectation. Autopsy revealed an angioinvasive disseminated aspergillosis affecting lungs, brain, myocardium, kidneys, thyroid glands in both cases, and endocardium, urinary bladder, lymph nodes, alimentary tract, nasal sinuses in one of the cases. Microbiology study of necropsic tissue showed Aspergillus flavusoryzae and likewise Candida albicans in one case. The latter finding suggest a combined fungal sepsis caused to candida and aspergillus.

[Neoplasms of the Meckel diverticulum. Apropos of 2 new cases].

We present two new cases of cancer in a Meckel's diverticulum, representing 3.3% of the complicated Meckel's diverticula encountered in our department. The first case was a carcinoid tumor encountered in a pathology study of an inflamed Meckel's diverticulum, and the second case was a leiomyosarcoma on a Meckel's diverticulum that presented as diverticular perforation. We emphasize the advanced age of the two patients and review the cases reported in Spain and in the Western literature.
