purpose: to define the demographic and clinical features of eyelid masses at a referral hospital over a 10-year period. methods: this is a retrospective record-based study on patients with eyelid masses during the above-mentioned period. data on epidemiologic and clinical features and therapeutic approaches were collected and analyzed. results: 551 patients were included in the study from which...

skin cancer has a broad and burdensome impact on the health and well-being of iranian and account for substantial health care costs to the nation. the first most common form of skin cancer is basal cell carcinoma (bcc); followed by the squamous cell carcinoma (scc) and the incidence of malignant melanoma (mm) is lower but is fatal. kaposi sarcoma (ks) is a tumor caused by human herpes virus 8. ...

background and objective: basal cell carcinoma (bcc) and squamous cell carcinoma (scc) are two common tumors of the skin. in some cases, distinction between bcc and scc can be difficult. this study aimed to clarify this uncertainty through immunohistochemical analysis. in this respect, epithelial membrane antigen (ema) and ber-ep4 are the two immunohistochemical markers on which we focus in dif...

odontogenic keratocysts (okcs) are one of the most frequent features of nevoid basal cell carcinoma syndrome (nbs). it is linked with mutation in the ptch gene. partial expression of the gene may result in occurrence of only multiple recurring okc. our patient presented with nine cysts with multiple recurrences over a period of 11 years without any other manifestation of the syndrome.

clinical and histopathological features of basal cell carcinoma (bcc) may differ according to the type of carcinogen involved. bcc arising from radiotherapy treatment has high incidence and its clinical and histopathological features may be different from bccs caused by other carcinogens. the aim of our study was to investigate any possible association between specific histopathological or clin...

Although basal cell carcinomas and squamous cell carcinomas are clinically and pathologically distinct, the molecular basis for these differ ences is not clear. We have used polymorphic microsatellite markers to determine the pattern and extent of chromosome losses in a series of 44 basal cell carcinomas and 47 squamous cell neoplasms of the skin. Basal cell carcinomas showed a distinctive alle...
