Two cases of suprasellar papillary craniopharyngioma are presented. The tumors are exclusively composed of well-formed papillary squamous epithelium and show morphologic homogeneity. There is no palisading basal layer in squamous epithelium. Clinical and radiologic findings, exclusive occurrence in adult and lack of calcification, are much different from conventional craniopharyngioma. Differences between papillary craniopharyngiom and conventional craniopharyngioma are discussed.

Endobronchial tuberculosis is granulomatous inflammation of the bronchial mucosa characterized by bronchial ulceration due to caseous necrosis. There is a good chance to expectorate cellular components of granulomas in the sputum. The author studied a cytologic series from 46 patients with endo-bronchial tuberculosis confirmed on fiberoptic bronchoscopic biopsy. The cytologic series consisted of 32 sputa, 41 washings, and 17 bronchial brushings, and were carefully screened for elongated epithelioid cells, Langhan's type giant cells, other multinucleated giant cells and caseous material. Elongated epithelioid cells were demonstrated in 9 sputa (28.1%), 30 bronchial washings (73.2%) and 11 brushing smears (64.7%). Langhans' giant cells were observed in two of 32 sputa (6.2%), six of 41 bronchial washings (14.6%) and four of 17 bronchial brushings (23.5%). The caseous materials were noted in 19 of 32 sputa (59.4%), 32 of 41 bronchial washings (78.0%), and 14 of 17 bronchial burshings (82.4%). It appeared that the pertinent cellular components of granulomas in sputa or bronchial secretions indicated a strong evidence of endobronchial tuberculosis of the lung.

BACKGROUND: Uterine leiomyoma is the most common pelvic tumor, occurring in 20-25% of women in reproductive age. Gonadotropin releasing hormone agonist (GnRHa) has been reognized as a temporary medical management for this disorder. The etiology of these tumors is unknown but it has been shown that the insulin-like growth factors (IGF-I, IGF-II) are promoters of growth in nongynecologic tumors. Several recent studies have suggested the possible role of IGFs in human leiomyoma growth. The IGF binding proteins (IGFBPs) are believed to modulate actions of IGF and to have IGF-independent actions. The purpose of this study was to evaluate the type of IGF and IGFBP which may be involved in leiomyoma growth and to investigate a possible IGF related mechanism of action of GnRHa. METHOD: The IGFs and IGFBPs were measured by double antibody radioimmunoassay, western ligand blot and immunoprecipitation in the tissue cytosols of normal uterine myometria (n=15), nontumorous myometria adjacent to a leiomyoma and leiomyoma from patients nontreated (n=15) and treated (n=10) with GnRHa. RESULTS: The mean IGF-I and IGF-II level were significantly higher in leiomyoma from untreated patients than in the adjacent myometrium and normal myometrium but no significant differences in these IGF levels between normal myometrium and adjacent myometrium were noted. The IGFBP-2, IGFBP-3 and 26kDa IGFBP were detected variably but IGFBP-4 was consistently present in all tissues. There were no significant differences in the relative intensity for IGFBP-4 and the frequency of IGFBPs between leiomyoma, adjacent myometrium and normal myometrium from untreated patients. The IGF-I, IGF-II levels and the relative intensity of IGFBP-4 in leiomyoma from GnRHa-treated patients were significantly lower than those in untreated patients, but these levels in the adjacent myometrium were comparable. The frequency of each IGFBP in leiomyoma and the adjacent myornetrium from GnRHa-treated patients did not significantly differ from untreated patients. CONCLUSION: Both IGF-I and IGF-II are involved in the growth of leiomyoma and GnRHa may in part act to decrease size of leiomyoma by regulating the local levels of IGF-I, IGF-II and IGFBP-4.

OBJECTIVES: To test the hypothesis that the endometrial stromal cells from patients with endometriosis responds differently to the insulin-like growth factor (IGF) compared with those from patients without endometriosis. METHODS: IGFs in peritoneal fluid (PF) from patients with endometriosis(n=18) and without endometriosis(n=12;control patients) were measured by radioimmunoassay. Endometrial stromal cells from patients with endometriosis and control patients were cultured in serum free media(SFM) in the presence or absence of PF or IGF-I(0.25-25 ng/ml) or IGF-II(5-50 ng/ml) and the proliferation of endometrial stromal cells were evaluated by [3H] thymidine incorporation test. All statistics were performed by ANOVA test and student's t-test. RESULTS: When added to SFM, IGF-I(1-25 ng/ml) increased thymidine incorporation in both endometrial stromal cells from patients with endometriosis and control patients in dose dependent manner and IGF-II(5-25 ng/ml) gave similar response in latter cells but not in former cells. Within low IGF-I(less than 100 ng/ml) PF group or high IGF-I(more than 100ng/ml) PF group, the type of endometrial stromal cells did not result in any difference in thymidine incorporation. However, regardless of the source of stromal cells, high IGF-I PF group produced a greater extent of thymidine incorporation than low IGF-I PF group in patients with endometriosis but not in control patients. Also, thymidine incorporation was higher in high IGF-I PF group of former patients than in the same group of latter patients. PF induced higher thymidine incorporation in endometrial stromal cells than the same levels(0.25-2.5 ng/ml) of IGF-I directly added to SFM. CONCLUSIONS: The effects of IGF-I in PF on endometrial stromal cells are similar regardless of their source and IGF-I is one of several growth factors that may participate in the growth of endometrial stromal cells in pelvic endometriosis.
