BACKGROUND: Trichoblastoma is a rare benign skin appendage tumor constituted mostly of follicular germinative cells. It can arise on any part of the body except the palms, soles, nail units and mucosal membranes. No case of it in breast skin has been reported before. Furthermore, fine needle aspiration cytology findings on this lesion have not been described before. CASE: A 76-year-old female presented with a firm nodule in her left breast. The tumor was well demarcated, about 1.5 cm in diameter. Fine needle aspiration cytology revealed clusters composed of relatively uniform cells with a high nuclear/cytoplasmic ratio. In the midst of some clusters, the tumor cells had a more abundant cytoplasm. Fibrocellular interstitium or dense cyanophilic acellular material occasionally was attached to them. The tumor cells had oval or fusiform nuclei that had fine, evenly dispersed chromatin. To exclude a diagnosis of breast cancer, it is important to recognize that the clusters are composed of basaloid cells with focal squamous eddies and that there is at least focally peripheral palisading. The histopathologic diagnosis was trichoblastoma. CONCLUSION: Fine needle aspiration cytology can distinguish trichoblastoma from malignant diseases of the breast and may be used to diagnose the lesion in conjunction with clinical findings.
A new computer program is reported that provides work schedules for nursing staff. Designed to run on the NEC PC-9801 personal computer using the N88-BASIC(86) interpreter, this program is intended for use by the senior nurses of each ward and removes most of the manual burden of staff work scheduling. The word work schedule can be created in only 90 seconds by the program and allows for individual nursing staff requests for particular work assignments.
