Pyelocaliceal diverticulum is a well recognized uncommon entity, usually noted incidentally on excretory urography by lack of clinical symptoms, About 500 cases had been reported with similar entity till 1975. We report 6 cases of stone-containing pyelocaliceal diverticula and additional one case and the literature has been reviewed briefly.

Infectious disease consultation contributes to optimal antibiotic use as well as improved treatment outcomes in many infectious diseases, especially severe infections like bacteremia. However, communication and language matter in consultations between clinicians. Communication barriers are even more complex among professionals who speak Korean, since there are significant challenges for practicing medicine while relying on language translations. This review aims to address some of the components that should be included in infectious diseases consultations for Korean-speaking specialists.

Growth stimulatory/inhibitory factors and their receptors are the important mediators of control of epithelial cell proliferation and differentiation. The aim of this study was to observe the distribution of epidermal growth factor receptor (EGFR) and transforming growth factor-beta1 type II receptor (TbetaRII) during carcinogenesis of oral squamous cell carcinoma (OSCC). Formalin fixed, paraffin embedded tissue from 25 oral leukoplakias (OL) and 15 OSCC was immunostained by avidin-biotin complex method. In OSCC, the carcinomatous area and the adjacent dysplastic/ hyperplastic area were examined. In OL, the hyperplasia and the epithelial dysplasia were examined. Monoclonal anti-EGFR Ab and polyclonal anti-TbetaRII Ab were applied. EGFR was mainly expressed in the basal layer and was increased with epithelial dysplasia in OL. TbetaRII was not detected in the basal cell layer and dysplastic area in OL. In contrast, the dysplastic area adjacent to OSCC showed positivity in the entire layer including the dysplastic area. In all cases of OSCC, both EGFR and TbetaRII showed positive reactions. EGFR was increased with the progression to the malignancy, and the expression pattern of TbetaR II was altered to be positive in the basal cell layer with progression to malignancy. These results suggest that the expression of EGFR appeared to be an early event and TbetaR II may be related to malignant transformation during oral carcinogenesis. The expression pattern of EGFR and TbetaR II may contribute to predict the risk of the development of carcinoma in oral premalignant lesions.

Partial Unilateral Lentiginosis (PUL) is a rare pigmentary disorder characterized by the numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of PUL. A 38-year-old woman had asymptomatic discrete small hyperpigmented macules that were scattered on the T7~L1 dermatomes on the left side of her trunk and were clearly demarcated in the midline on both anterior and posterior sides. In the other case, an 18- year-old woman had hyperpigmented macules that were scattered on the left neck, shoulder, and anterior chest. Other anomalies including neurofibromatosis, neurologic anomalies, and multiple lentiginous syndrome were not related in both cases. We report two cases of PUL having no other anomalies.

Pleomorphic xanthoastrocytoma is a rare tumor, presenting superficially over the cerebral hemispheres of young subjects. We report a case of Pleomorphic xanthoastrocytoma of the cervical cord in view of its unusual location. The patient is a 20-year-old female, presenting with left neck pain radiating to the left shoulder one month before the admission. Magnetic resonance imaging revealed a high signal lesion in the upper cervical cord lower brainstem in T2 weighted image. On operation, intramedullary tumor was present and it was relatively well delineated. Near-total removal of the spinal cord mass was done. Microscopically, the tumor was composed of pleomorphic astrocytes, which were spindle-shaped with cytoplasmic processes and hyperchromatic nuclei. Other cells were round with vesicular nuclei and abundant eosinophilic cytoplasm. A few giant cells were seen. Despite the marked pleomorphism, mitosis or necrosis was not encountered. Scattered foamy cells were also seen, which showed negative staining in GFAP immunostaining in contrast to other GFAP-positive tumors cells.
