The spatiotemporal control of cell divisions is a key factor in epithelial morphogenesis and patterning. Mao et al (2013) now describe how differential rates of proliferation within the Drosophila wing disc epithelium give rise to anisotropic tissue tension in peripheral/proximal regions of the disc. Such global tissue tension anisotropy in turn determines the orientation of cell divisions by c...

Sarcomas, or tumors derived from the connective-tissue elements, are rare among the malignancies of the lip. The only available statistics as to sarcoma of the lip are from the Gottingen Pathological Institute, where 2 cases were found among 1,248 sarcoma cases (0.16 per cent). No mention was made as to whether the lesions were on the vermilion border, and the type of sarcoma is not specified. ...

Adenoma of the non-pigmented epithelium of the ciliary body (ANPCE) is a relatively uncommon lesion usually presenting in the non-pigmented epithelium of the ciliary body, which belongs to the neuroectodermal origin. Histologically, this tumor consisted of sheets, cords, and tubules occasionally forming glandular configurations. The cells of the tumor had abundant eosinophilic cytoplasm with ro...

PURPOSE We report on the histopathology and clinical features of 21 cases of feline conjunctival melanoma. METHODS A total of 18 cases are from the COPLOW collection and three cases from Antech Diagnostics. We tabulated the location of the tumor, pigmentation, cell shape, mitotic index and presence of multinucleated tumor cells. Surveys were sent to referring ophthalmologists to obtain furthe...
