Basal cell carcinoma with collagenous crystalloids.
We describe here a unique feature seen in a case of conventional basal cell carcinoma of the skin. In the central portion of the tumor, clusters of collagenous crystalloids composed of radially arranged needle-shaped fibers were found. Such distinct extracellular matrix deposits may occur in rare cases of pleomorphic adenomas and myoepitheliomas of salivary glands, but to the best of our knowledge, they have never before been described in basal cell carcinoma of the skin.
