Angiolymphoid hyperplasia with eosinophilia: report of a large-sized scalp lesion

In this report, a case is presented with large recurrent, benign, vascular and proliferative lesion on the scalp. Complete surgical excision of the tumor mass and split thickness skin grafting of the defect had favorable results with no recurrences after 24-month follow-up.     

Examination of the dermal lymphatics in psoriasis⋆

In recent years, research on the aetiology of psoriasis has focused on immune aetiopathogenesis. However, in the last few years, research on the immunoloogical changes in psoriasis has failed to mention the lymphatics. Also, studies emphasizing the importance of the dermal lymphatics have neglected the lymphatic changes seen in psoriasis. Therefore, we decided to put this matter back on the agenda. Skin biopsies from 20 patients with psoriasis vulgaris were examined lymphatically by light microscopy using the orcein stain. We found a considerable increase in both number and dilatation in the lymphatics of psoriatic plaques, compared with both the clinically uninvolved skin of the psoriatic patients and also the skin of the control group.     

Dysembryoplastic neuroepithelial tumor in the left lateral ventricle.

Extracortical location of dysembryoplastic neuroepithelial tumor (DNT) is rare. We present a case of DNT localized in the left lateral ventricle of a 21-year-old female patient. Magnetic resonance imaging of the brain showed a round mass lesion in the floor of the anterior horn of the left lateral ventricle. The lesion was hypointense on T (1)-weighted images and slightly hyperintense on T (2)-weighted images without contrast enhancement. Total removal of the yellowish-white colored soft tumor was performed through a transcallosal approach. Histologically, the tumor was of simple type of DNT that was composed of small oligodendrogliocytes clustered tightly about perivascular spaces with neurons floating in mucoid pools showing an eosinophilic fibrillary matrix in the background. The recognition of DNT with an unusual location in lateral ventricle has therapeutic and prognostic significance since DNT is curable by surgical excision and radiation therapy is of no obvious benefit.     

Pulmonale Verkalkungen infolge einer Escherichia-coli-Pneumonie

We report a neonate (gestational age 24 5/7 weeks) who developed severe sepsis with Escherichia coli pneumonia on the 11th day of life. Nine weeks after the initial diagnosis of E. coli pneumonia, calcifications in the right lung were diagnosed. After intermittent antibiotic therapy for 98 days, invasive ventilation for 47 days, and nasal CPAP (continuous positive airway pressure) for 65 days, the infant was discharged on supplementary oxygen therapy.
