[Cervical metastasis of squamous cell carcinoma of unknown origin: experience at Hospital de Sant Pau, Barcelona, Spain]. / Metástasis cervical de carcinoma escamoso sin primario conocido: experiencia en el HSCSP.

Between 1984 and 1992, 18 cases of cervical metastasis of squamous cell or anaplastic carcinoma (1% of all head and neck tumors) were seen at the Hospital de la Santa Creu i Sant Pau (Barcelona, Spain). Fifteen patients underwent radical surgery: 1 N1, 4 N2A and 10N3, N1 and N2A patients underwent surgery followed by radiotherapy. The 10 N3 patients began with neoadjuvant chemotherapy (cisplatin and 5-fluorouracil), then 8 had radical neck dissection and 2 had palliative radiotherapy. The primary tumor was found in 11%. The 5-year survival rate was 40% in N1+2A and 11% in N3. Chemotherapy did not improve survival in advanced disease, but it facilitated neck dissection and selection of the group with the prognosis.

Cytologic diagnosis of extrapulmonary Pneumocystis carinii infection in pleural and ascitic fluid. Report of a case in a patient with the acquired immunodeficiency syndrome.

We present a case of an extrapulmonary Pneumocystis carinii infection in a human immunodeficiency virus-positive patient undergoing prophylactic treatment with pentamidine. The diagnosis was established in pleural and ascitic fluid, and the patient died before starting specific systemic treatment. We discuss the cytologic differences between pulmonary and extrapulmonary infections and the importance of careful screening for this pathogen in immunosuppressed patients.
