Polypoid basal cell carcinoma.
Summary of "Polypoid basal cell carcinoma."
The basal cell carcinoma is a malignant tumor which originates from the epidermal stem cells. The polypoid basal cell carcinoma is an uncommon variant. We report on a 70-year-old man with a red nodule on his left breast. Clinical and histopathologic criteria led to the diagnosis of polypoid basal cell carcinoma. This variant is characterized by exophytic, polypoid growth. Histologically, the aggregates of tumor cells are usually limited to the polypoid zone.

Medical and Biotech [MESH] Definitions
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
A skin carcinoma that histologically exhibits both basal and squamous elements. (From Dorland, 27th ed)
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A heterogeneous group of sporadic or hereditary carcinoma derived from cells of the KIDNEYS. There are several subtypes including the clear cells, the papillary, the chromophobe, the collecting duct, the spindle cells (sarcomatoid), or mixed cell-type carcinoma.
A surgical technique used primarily in the treatment of skin neoplasms, especially basal cell or squamous cell carcinoma of the skin. This procedure is a microscopically controlled excision of cutaneous tumors either after fixation in vivo or after freezing the tissue. Serial examinations of fresh tissue specimens are most frequently done.
