Clinical forms of basal cell carcinoma
Basal cell carcinoma is characterized by very heterogeneous from a clinical standpoint, which can sometimes make diagnosis difficult. Its most common location is on the face. It has a slow growing and painless, although as noted earlier, the evolution can produce invasion and destruction of adjacent structures.
The most common presentation is as pearly papule with teleangiectasia on its surface, which tends to be localized in the medial canthus, nose, or forehead. Corresponds to 95% of basal cell carcinomas. In the evolution may ulcerate in the center of the lesion, although the edges remain pearly papules features. In some cases the ulceration occurs early and massive way, then called ulcus Rodens, a less frequent but more aggressive.
Other clinical forms are:
* Basal Cell Carcinoma sclerodermatous: Board shiny smooth, flat and sometimes depressed slightly ill-defined borders resembling morphea. Sometimes we can see the look on their margins teleangiectasia pearl and typical of this tumor. Characteristically, the growth in depth of these lesions over the limits that we see clinically.
* Superficial Basal Cell Carcinoma: a raised red plaque with scaly surface, which is typically located in the trunk. Sometimes it can appear as multiple lesions in this case being generally related to previous exposure to arsenic.
* All clinical forms of basal cell carcinoma can appear as pigmented lesions, making it difficult differential diagnosis with melanoma.
