[Alveolar hemorrhage in mixed cryoglobulinemia associated with hepatitis C virus infection]. / Hemorragia alveolar en el seno de una crioglobulinemia mixta asociada a infección por el virus de la hepatitis C.

Alveolar hemorrhage in mixed cryoglobulinemia associated with hepatitis C virus infection. A 61 year-old woman with type II mixed cryoglobulinemia associated to hepatitis C virus infection has suffered alveolar hemorrhage with multiple pulmonary infiltrates, purpura, glomerulonephritis and polyneuropathy. The respiratory and kidney findings resolved with prednisone, but glomerulonephritis reappeared when interferon-alpha treatment was started and prednisone was reduced. This is the third case of alveolar hemorrhage and glomerulonephritis associated with mixed cryoglobulinemia reported in the literature. The lung involvement in mixed cryoglobulinemia is reviewed. The clinic manifestations (asthma, pleural effusion, hemoptysis or pulmonary fibrosis) are uncommon, but the lung involvement is very frequent if roentgenographic signs and necropsy findings are assessed.

[Monostotic fibrous dysplasia of the upper maxilla. A case report]. / Displasia fibrosa monostótica de maxilar superior. Presentación de un caso clínico.

Fibrous dysplasia is a rare bone condition characterized by the replacement of healthy bone by fibrous tissue and different grades of bone metaplasia. It may affect one (monostotic) or more bones (polyostotic). We present the case of a patient with monostotic fibrous dysplasia of the upper maxilla and analyze the clinical characteristics, diagnostic and therapeutic aspects, and the bibliography of the disease.

[Laryngeal neuroendocrine carcinoma. Report of a clinical case]. / Carcinoma neuroendocrino de laringe. Presentación de un caso clínico.

A case of neuroendocrine small cell carcinoma is described in a 79 year-old male. This tumor is an unusual laryngeal carcinoma (the incidence is slightly lower than 1% of all carcinomas) with an aggressive biological behaviour. This work analyzes its clinical, pathological, therapeutical and evolutive aspects, and compare this case to those reported in the literature.
