A computerised, retrospective study of 818 patients with sarcoidosis was analysed to study the prognosis of each individual manifestation of the disease. The good prognosis of erythema nodosum, acute arthritis and bilateral hilar lymphadenopathy was confirmed, though 16 per cent of patients presenting with erythema nodosum pursued a chronic course.

Epithelial polyps of the prostatic urethra are an uncommon and histologically heterogeneous group of lesions. We review the clinical and histologic features of a series of seven such polyps. Six were composed of prostatic-type epithelium. In five instances the epithelium was entirely histologically identical to that of normal prostate. One case contained(More)
A case of fatal myeloencephalopathy secondary to accidental intrathecal administration of vincristine is reported in a 16-year-old boy. He underwent a progressive ascending chemical meningoencephalitis leading to coma, and died 36 days after the injection. Multiple samples of cerebrospinal fluid (CSF) and serum were assayed for vincristine sulfate. CSF(More)
Polyclonal antisera against chitin and chitin oligomers were used to stain Pneumocystis carinii by the immunoperoxidase technique in Formalin-fixed, paraffin-embedded sections of four human lung biopsies and in alcohol-fixed, paraffin-embedded cell blocks of two bronchioloalveolar lavage specimens from infected human patients. In all cases, the antisera(More)
PURPOSE We report a case of small-cell undifferentiated carcinoma with neuroendocrine (SCUCN) of the gallbladder in a 67-year-old man who presented with suspected cholelithiasis. Treatment included a cholecystectomy and a 4-cycle course of etoposide and carboplatin. CONCLUSIONS Small-cell undifferentiated carcinoma with neuroendocrine features of the(More)
We describe 17 atypical carcinoid tumors of the lung that are histologically intermediate between small-cell undifferentiated carcinoma and typical carcinoid tumor. Atypical carcinoid tumors have a distinctive microscopic pattern of nests, trabeculae, and ribbons of intermediate-sized, moderately pleomorphic cells that lack the nuclear molding and dense(More)
A 77-year-old man had a papillary neoplasm of the prostatic urethra removed by transurethral resection. Light microscopically, much of the tissue consisted of a benign villous polyp lined by prostatic epithelium. An adenocarcinoma with cells that resembled those of uterine endometrial carcinoma was also present within the villous polyp. Using(More)
