Primary pure squamous cell carcinoma of the breast diagnosed by fine-needle aspiration cytology: a case study using liquid-based cytology.

Pure primary squamous cell carcinoma (SCC) is an extremely rare type of breast tumor. We report one of such cases in a 32-year-old woman, diagnosed by fine-needle aspiration cytology (FNAC). Aspiration smears were characterized by squamous cells, both isolated and in aggregates, at various stages of maturation. The tumor was excised, and the histologic sections confirmed the cytologic diagnosis. Pure primary SCC of the breast has a distinctive cytomorphologic appearance, and diagnosis of this tumor by FNAC is possible. For its diagnosis, the exclusion of SCC of local cutaneous structures and metastasis of distant squamous carcinoma are mandatory.

[Imiquimod in treatment of palpebral mycosis fungoides]. / Imiquimod como tratamiento de la micosis fungoide palpebral.

CLINICAL CASE: Our patient was a 37-year-old male with palpebral mycosis fungoides, the most common T-cell cutaneous lymphoma. He had been treated previously with topical corticosteroids. We treated him with Imiquimod cream (5%) three times a week. DISCUSSION: A clinical improvement was obtained with this drug, so we believe immuno-modulating agents need to be considered in the treatment of palpebral mycosis fungoides, especially because of its capacity of being a reflection of leukaemia.

Malignant retroperitoneal paraganglioma with intranuclear vacuoles in a fine needle aspirate. A case report.

The cytologic findings in fine needle aspiration smears and cell blocks from a malignant retroperitoneal paraganglioma with subsequent histologic confirmation are described. The aspirate contained clusters of cells with ill-defined borders, often varied in size, round or oval nuclei and marked anisokaryosis. An unusual feature was the presence of prominent intranuclear vacuoles in some cells. The histologic and ultrastructural findings, as well as the results of histochemical and immunodiagnostic staining, are also presented.

Report of three cases of Wunderlich Syndrome secondary to renal adenocarcinoma, hydronephrosis and non-filar blood dyscrasia, highlighting its uncommon etiology. Brief review of the etiopathogenic, diagnostic and therapeutical aspects, pointing out the relevance of renal ultrasonography and, most specially, abdominal CAT to achieve a definitive diagnosis and to determine the attitude to follow, trying to use conservative surgery whenever possible, although our three cases were treated with nephrectomy.

[Infrequent retroperitoneal tumor: benign schwannoma]. / Tumor retroperitoneal infrecuente: Schwannoma benigno.

Case report of a retroperitoneal benign Schwannoma diagnosed accidentally during ultrasound scanning for a different pathology and treated by surgical exeresis. The diagnostic and therapeutic features of this rare neoplasia are reviewed.

The different clinical, diagnostic and therapeutic aspects of this neoplasia are discussed.

[Chromophobe renal carcinoma. Case report]. / Carcinoma cromófobo renal. Aportación de dos casos.

Human chromophobe renal cell carcinoma is an infrequent neoplasm, recently descripted (1985). It is very important to separate it from the renal cell carcinoma due to its better prognosis. Presentation of the clinical, radiographic and histological features of two cases of chromophobe renal cell carcinoma, diagnosed and treated in our Centre.
