  • solitary peripheral ciliated glandular papillomas of the lung a report of 3 cases
    The American Journal of Surgical Pathology, 2008
    Co-Authors: Shinsuke Aida, Ichiyo Ohara, Hideyuki Shimazaki, Sho Ogata, Yuichi Ozeki, Seiichi Tamai
    Abstract:

    : We report 3 cases of solitary papillomas located in peripheral regions of the lung that are extremely rare in the literature. The patients were 75-year-old and 72-year-old men and a 53-year-old woman. One patient complained of recurrent hemoptysis. The other 2 had no symptoms, but abnormal nodular shadows were revealed by chest radiographs during a health check. The maximum diameters of the tumors were 1.0, 1.4, and 1.1 cm, respectively. The 3 tumors gave almost the same histologic findings. Papillomatous fronds lined by a Stratified Columnar Epithelium were seen in the lumens of peripheral bronchi, bronchioles, or alveoli. The Stratified Columnar Epithelium consisted of ciliated, mucous, and basal cells. The neoplastic Epithelium extended to the alveolar region and showed a similar appearance to bronchioloalveolar or papillary type adenocarcinomas. For differential diagnosis, it is noteworthy that endobronchiolar papillomatous fronds constantly exist and spreading along alveolar walls is limited in adjacent alveoli in peripheral papillomas. The presence of ciliated cells and basal cells is considered an important finding to suggest benign character of the lesion.

  • HISTOMORPHOLOGICAL OBSERVATION ON TESTES AND EPIDIDYMIS OF YAK (BOS GRUNNIENS)
    International Journal of Pure and Applied Zoology, 2019
    Co-Authors: Deka A, Deori S, Paul, Chakravarty P
    Abstract:

    In present study, one pair of testes and epididymis of Yak (Bos grunniens) was utilized. In cross section of testes, tunica albugenia, tunica vasculosa layer along with cross section of seminiferous tubules were observed. The cross section of seminiferous tubules contained basement membrane, sertoli cells, spermatogonia, spermatids and spermatocytes. The Sertoli cells were pyramidal shaped and rest on basement membrane. The spermatogonia were found among the Sertoli cells. In the cross section of epididymis of pseudo Stratified Columnar Epithelium, stereo cilia, lumen of seminiferous tubules and smooth muscles were observed. The size of the lumen of the seminiferous tubules were larger compared to the size of the seminiferous tubules of testes.
