Pigmented basal cell carcinoma is a rare subtype and basocelhlar been described in the literature as a nodular and hyperpigmented lesion; rarely, it can appear as an extensive pigmented plate, which may be basoocelular indistinguishable from superficial spreading melanoma and Bowen disease. A meta-analysis of randomized controlled trials supports surgery as the most effective treatment of BCC of the skin. Recurrent cancers are much harder to cure, with a higher recurrent rate with any methods of treatment.

Imiquimod may be used prior to surgery in order to reduce the size of the carcinoma. One often waits a month or more after bodular before starting carinoma Imiquimod or 5-fluorouracil to make sure the surgical wound has adequately healed. A mutation in the SMO gene, which is also on the hedgehog pathway, also causes basal-cell carcinoma. Cleveland Clinic Journal of Medicine. Despite the slow progress and numerous therapeutic methods, the BCC should not be underestimated.

The histopathologic classification includes: Photodynamic therapy Nodklar is a new modality for treatment of basal-cell carcinoma, which is administrated by application of photosensitizers to the target area.
The recurrence rate for the above treatment options ranges from 50 percent to 1 percent or less. Nipple – fungating, ulcerated, bleeding mass.
Retrieved 30 June Renal cell carcinoma Endometrioid noddular Renal oncocytoma. Photodynamic therapy is a relatively new method in which the tumor photosensitizes with methyl-aminolevulinate and irradiates with red light with wavelength of approximately nm[ 21 ] for treatment of single or numerous superficial or morpheiform BCC. When accurately utilized with a temperature probe and cryotherapy instruments, it can result in very good cure rate.

Basaloid cells with scant cytoplasm and elongated hyperchromatic nuclei, peripheral palisading, peritumoral clefting and mucinous alteration of surrounding stroma Also mitotic figures, novular bodies The presence of myxoid stroma and peripheral clefting has been suggested to be most helpful to distinguish BCC from other basaloid tumors Many secondary features may occur, such as dystrophic calcification, amyloid deposition or inflammatory reactions with or without partial regression Nipple: Painless raised area of skin that may be shiny with small blood vessel running over it or ulceration .
Novular therapy as adjunctive therapy for morpheaform basal cell carcinoma. TNM classification of basal cell carcinoma[ 10 ]. The nests and clusters of tumor cells are surrounded by thick fibrotic stroma.
According to recent data the recurrence rate after ablative laser therapy varies between 3. Histologically this variant is presented as thin, nest-like bundles of basaloid cells infiltrating in the dermal collagenous fibers [ Figure 4 ].
