Abstract
Systemic sclerosis is a generalized disorder of connective tissue, in which the pattern of disease extent, progression and outcome is heterogenous. To determine clinical features, disease extent and progression, we studied our patients in two phases of disease early (the first 3 years) and late phases (after 6 years of disease). 19 patients had diffuse cutaneous and 34 patients had limited cutaneous scleroderma. In patients with diffuse cutaneous scleroderma, disease progression has occurred mostly in the early phase of disease, but in patients with limited cutaneous scleroderma, disease progression was slow and incidious, so disease progression has occurred mostly in the late phase of the disease, thus raynaud's phenomenon, telangiectasia, hyperpigmentation and esophagitis were observed more in the late phase of the disease (statistically significant). In comparison of two groups, early and extensive organ involvement was observed in patients with diffuse cutaneous sclerodema.

Abstract
Squamous cell carcinoma, a cancer of keratinocytes origin, mostly involves sun-exposed areas of the skin. To study the pathologic and demographic features of this disease, records of 395 patients of squamous cell carcinoma of skin and lip were reviewed. Most of the patients (83%) aged 40 years or more at the time of diagnosis. Respectively, 74.4% and 75.8% of cases with skin and lower lip carcinoma were men, but in upper lip cases frequencies of both sexes were equal. The number of patients referred from western and north-western provinces were much more than those of other provinces of the country. The most frequent histologic stage was grade I (53% and 58.8% in skin and lip carcinoma, respectively), showing that most patients visit physicians early enough, and are diagnosed in early stages of the disease.
