[Pleural deciduoid mesothelioma: A report of 3 cases and a review of the literature]. / Mesotelioma deciduoide pleural: presentación de 3 casos y revisión de la literatura.

Deciduoid mesothelioma is an uncommon histological variant of epithelial mesothelioma which is extremely clinically aggressive. We report 3 cases of pleural caducoid mesothelioma in women of 75, 74 and 23 years of age. All patients presented with dyspnoea, vomiting and pelvic pain. Their imaging studies showed nodular pleuropericardic thickening, a parietal pleuropericardic solid mass and a large thoracic mass, respectively. Only one of them could be treated with chemotherapy, surgery and radiotherapy. Post diagnostic survival was 24 days, 1 month and 17 months respectively (mean 6.2 months). We describe the clinicopathological and immunohistochemical findings together with a review of the relevant literature.

[Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia with tumorlet formation: A case report and review of the literature]. / Hiperplasia difusa idiopática de células neuroendocrinas pulmonares con formación de tumorlets: presentación de un caso clínico y revisión de la literatura.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia is an infrequent lesion recently classified by the WHO as preinvasive. It can present with the formation of tumorlets (neuroendocrine cell groups up to 5 mm) which result in a typical histological and radiological image. We report a case of a 67-year-old women who presented with a chronic cough. The CT scan showed bilateral minute, multiple pulmonary nodules. A biopsy revealed a diffuse idiopathic pulmonary neuroendocrine cell hyperplasia with several tumorlets. After two years of follow-up, imaging studies showed no significant changes.

[Physiopathology of vulvar elephantiasis of filarial origin. A case report]. / Fisiopatología de la elefantiasis vulvar de origen filarial. A propósito de un caso.

Genital filariasis is an uncommon infectious entity in the western world. It has characteristic clinical features and a well-recognized endemic area that causes typical histological alterations. We report a case of a 32-year-old woman, a native of Mozambique, who presented with vulvar elephantiasis as a pendulous tumor with a maximum diameter of 15cm. A large part of the genital mass was resected. Microscopically, hyperkeratosis with irregular acanthosis, a notable thickening of dermis with dense fibrosis and inflammatory clusters of patchy distribution, mostly made up of plasma cells, was seen. Since the parasite was not observed, an exclusion diagnosis was made, as frequently happens with this lesion.
